Electricity Storage Unit as An Opportunity for Renewable Energies
Burdens on the climate and environment, finite reserves and the constant risk of supply bottlenecks: Fossil fuels have a lot of disadvantages. Nevertheless, a large proportion of electricity in this country still comes from coal, oil and natural gas. Although the switch to renewable energies is a declared goal of many governments, progress is slow.
Too slowly for some. And so private individuals, companies and municipalities are gradually taking their energy supply into their own hands. Photovoltaic systems (also called solar generators or simply PV systems) are an excellent way to secure your own power supply in a climate-friendly and sustainable way.
The first step to buying a home battery solar system is to inform yourself comprehensively. By reading this page, you are on the right track. To ensure that you are optimally prepared for the next step - the actual purchase of the solar storage system - we have put together a few more helpful tips.
What is Home Battery Backup System?
The sun is pure energy and in all likelihood its fuel will last for several billion years. So it is only logical to use this energy here on earth. One well-known possibility is photovoltaic systems. These convert the radiation emitted by the sun into electricity by means of lithium solar battery. Because the systems are available in all sizes, they are suitable for private households as well as for large-scale projects.
Photovoltaics Deliver Energy Unevenly
Despite everything, PV systems do have one small "downside": Depending on the weather, time of day and season, different amounts of solar radiation reach the system. As a result, more energy than needed may be available on sunny days. At night or when the sky is gray, on the other hand, electricity production falls below the demand limit.
In both cases, there is the option of using the public power grid. On the one hand, you can feed your surplus electrical energy into the general grid for a fee. On the other hand, you can fall back on the grid supply and buy additional electricity as needed. However, these solutions are neither financially nor environmentally efficient.
If you want to make your power supply as sustainable and self-determined as possible, a home battery for solar can help. As the name suggests, this device stores the (surplus) electricity from your photovoltaic system. Afterwards, the electrical energy is available at any time and you can call it up as needed. The public grid only comes into play again when your lithium solar battery is completely full or empty.
In this way, you can make your power supply independent to a large extent. The size of your photovoltaic system, the charging capacity of your electricity storage unit and your individual electricity consumption determine how independent you are from the public grid.
You may only store energy from your PV system in your home battery solar system, not from the public grid.
Determine Exact Power Needs of Your Residential It is important to choose the correct storage capacity. To do this, you should look at how much electricity your home has consumed over the last five years. From these figures, you can calculate the average annual consumption and make projections for the next few years. Be sure to take into account possible developments, such as starting and growing a family. You should also take future purchases into account (e.g. an electric car or a new heating system). Optionally, you can get support from someone who has the expertise to determine your electricity needs.
Balance the Size of Your Home Battery Backup Systems Precisely Based on the determined power demand, you can choose the optimal home battery storage capacity for you - you already know the disadvantages of an inappropriately sized storage. However, in addition to the power demand, the size (or rather capacity) of your PV system also plays a decisive role. As a rough rule of thumb: Per kilowatt peak (the unit for the maximum power) of your PV system, the lithium solar battery should offer 1 kWh capacity.
Decide whether you prefer AC-coupling or DC-coupling
You can connect your home battery backup systems to your PV system in two ways: either on the alternating current (AC) side or on the direct current (DC) side. Both options have advantages and disadvantages.
Through AC Coupling:The home battery storage unit and the PV system are connected via the house's AC grid. As the solar panels produce DC electricity, the system's inverter converts it to AC. The inverter of the home battery backup system then converts it back to DC. When you use the stored energy in your home, it is converted back to AC. This is a large conversion process and efficiency is therefore compromised. However, AC-coupled storage systems have one decisive advantage: they are installed independently of the PV system and are therefore particularly suitable for retrofitting.
Hybrid Storage: This home battery solar system combines AC and DC systems. This means that no external inverter is required and the PV modules are connected directly to the storage system.
Through DC coupling: In contrast, DC-coupled home battery solar systems are less flexible and are mainly suitable for new PV systems. They are connected to the PV system on the DC side. The electricity is only converted when you discharge the home battery backup power supply. This means that there are fewer losses. In addition, only one inverter is required. This saves you components, which is why the DC storage units take up less space. Installation is also less complex. At the same time, however, there is an upper limit regarding the size of compatible systems.
Storing Energy for Short and Long Periods
At the same time, you can relieve the public grid with some home battery solar systems: so-called home battery solar systems provide so-called control power and help to guarantee the stability of the grid frequency.
Together with mobile storage units - which are mainly used for seasonal energy storage - home battery solar system belong to the type of short-term storage units. These are batteries, either lead-acid or lithium-ion battery based (more on this later). Their energy storage is not designed for longer periods of time. Rather, they store electrical energy for only a few seconds, minutes, or hours at most. You can't accumulate a "stockpile" of solar energy this way, but you can bridge sunless days and night very effectively.
Long-term storage of large masses of energy is comparatively difficult. There are also long-term storage systems that only run through a few cycles a year. However, these are usually complex power-to-gas plants (here, in simplified terms, energy is stored in hydrogen or methane) and large hydroelectric storage plants - not solutions that can be considered for private households.
Control power is something like a reserve. In the event of grid disturbances, it secures the necessary power supply for end consumers.
In this page, we refer exclusively to short-term storage for private domestic use.
Know the Properties of Lead-acid and Lithium-ion Batteries
With modern home electricity storage systems, you have a choice between two battery technologies: Lead-acid and lithium-ion batteries. Which one you choose depends on your personal preferences. Both technologies have their advantages - and their shortcomings.
Lead batteries are the classic of the battery world. They have been around for more than a century, which is why they are used in everything from car batteries to emergency generators. You can dispose of them just as easily. In addition, lead batteries are less expensive than their lithium-ion competitors. The main disadvantage of lead batteries - apart from their significantly higher weight - is their short service life. This is often less than 10 years or around 3000 charging cycles. One reason for this is the high charging and discharging currents. In addition, lead batteries wear out more easily: Discharging them by more than 50 % damages the battery. To protect the battery, the BMS therefore limits the energy drain to half of the gross capacity. With a lead battery, you should therefore always buy twice as much capacity as you actually need. Furthermore, lead-acid batteries need forced ventilation to remove any gases that may occur. Their system efficiency is around 70 %.
Lithium-ion batteries have enjoyed increasing popularity for several years. This is no coincidence: with a service life of around 10 to 20 years and 6,000 charging cycles, their potential service life is far longer than that of lead batteries. Their maximum depth of discharge is also impressive - instead of the 50 percent of lead batteries, 80 to 90 % is possible. Their efficiency is 90 %. And they have a higher energy density, which means they can store more energy per kilogram. With the same capacity, lithium-ion batteries are thus lighter and more compact than a suitable counterpart made of lead. They are also considered to be safe to operate and uncomplicated to install. So what exactly is the disadvantage of this battery technology? Lithium-ion batteries are significantly more expensive than lead batteries. However, their price is falling continuously. The more widespread the technology becomes, the cheaper lithium-ion batteries will be in the future.
You may only store energy from your PV system in your home battery backup systems, not from the public grid.
Consider Whether You Want To Store The Current in Single-phase or Three-phase
AC and DC are not the only differentiating criteria for electricity. The number of phases is also relevant. Usually, three-phase alternating current flows in the public grid. This means that three individual currents flow, slightly offset from each other. This makes the current stronger - three-phase alternating current is therefore colloquially (incorrectly) referred to as strong current.
The strong three-phase alternating current makes sense above all in places with high energy demands, for example in industrial plants or transport systems. In the average household, however, at most the stove requires such strong current. Normal household appliances are content with the weaker single-phase current. You should therefore consider whether you want to store the electrical energy from your PV system in single-phase or three-phase form.
For the majority of private residential, single-phase storage is sufficient. The technical implementation is easier and cheaper. If your photovoltaic system is particularly large and powerful, or if you want to operate several energy-intensive devices, three-phase storage is a possibility. It is best to get advice on this decision from BSLBATT with expert knowledge.
Invest in quality and benefit from a long service life! PV systems can operate reliably for many years and even several decades. In the best case, you don't want to have to replace your lithium solar battery bank system during this time - or at least as rarely as possible.
New Construction and Retrofitting of an Home Battery Solar System
Be it due to neglect, lack of awareness or for financial or space reasons: Not always a solar home battery is installed directly during the new construction of a photovoltaic system. This is not a bad thing. Because normally it is no problem to retrofit a solar power system with a home battery backup system. However, it is more advantageous to plan the PV system directly with home battery backup systems.
What a Solar Home Battery Means for Your Household
Many operators of private PV systems do not even consider electricity storage for home when building their new system. One part does not even know that this possibility exists. The other is often not aware of how immense the difference is with such a device.
SOLAR HOME BATTERY MEANS INDEPENDENCE
Because you make yourself even more independent of the public power grid: Instead of an average of 30 % without electricity storage batteries, with electricity storage batteries you get an average of 50 % of your electricity from solar energy. With an exemplary consumption of 4000 kWh per year, that's 2000 kWh.
In addition to the financial aspect (at a price of 30 cents per kWh, you can save 600 dollars every year in our example), the "climate protection" factor is also an additional motivator. The more energy you can use from your PV system, the higher your personal share of green electricity. In any case, it is worth considering an electricity storage unit from the outset when planning a photovoltaic system.
Without home battery backup power supply, your surplus solar energy is fed into the public grid. From an economic point of view, a home battery solar system pays off especially if the feed-in tariff is lower than your electricity price.
Mounting the Home Battery Solar System
There is another reason why it is advisable to include an solar home battery storage in the planning as early as possible: the devices require a lot of space. They are available in various sizes and in most cases there are also suitable solutions for retrofitting. But if you plan ahead, you can assign the solar home battery storage the optimal location right from the start.
Consider Dimensions and Weight
Think about where the electricity storage battery will not get in the way and where it will fit in perfectly aesthetically (although this is of course of secondary importance). By taking measurements, you'll find out where there's room for the device in the first place.
Do not forget that in addition to the dimensions, the weight of a solar power storage unit is also considerable. The floor on which the device is placed should be stable and able to withstand the weight of the solar power storage unit without any problems. A popular location is the basement or the house connection room near the meter cabinet. However, other rooms are also possible, such as the garage.
BSLBATT designs and manufactures POWER STORAGE UNITS of different sizes and weights for different residential and small business electricity needs.
Installation Should Only Be Carried Out by Professionals
Buy a electricity storage battery, plug it in and you're done? Unfortunately, it's not quite that simple. From planning to transport to installation, the installation of an electricity storage battery is not for amateurs. Get professional support and have your electricity storage batteries delivered and connected by specialists.
After all, simply installing the electricity storage battery is not enough - technical adjustments may be necessary, such as replacing the inverter of your PV system. Ideally, you will find a specialist company that offers maintenance contracts in addition to installation and issues you with a storage passport.

Maintenance of an Solar Home Battery Bank
Trust is good, control is better - this wisdom also applies to solar home battery bank. Qualitative models in particular generally require little maintenance. Nevertheless, you should have your solar home battery bank checked by a specialist once a year. If you operate the solar battery storage commercially, you are even obliged to do so.
This is What Maintenance Looks Like
During maintenance, the home battery solar system is checked for proper functioning. Among other things, the specialist checks
The general condition: Are there any visible damages? Is there a risk of moisture, dirt or dust deposits? Are warning and information signs in their intended positions?
The safety: Are all covers and connections in place? Are protective measures still active? Are there any weak points?
The environment: Are the ambient conditions (for example, the temperature) still optimal? Is the ventilation sufficient? Have there been any modifications?
The general functionality: Is the system working as expected? Do data backups and documentation run reliably? Do functions need to be updated or new regulations implemented?
The status of the lithium battery: Are resistance and voltage adequate? Does the capacity meet expectations? Is the temperature normal?
To check, the specialist performs various tests and measurements. Especially with modern models, a lot of information can be obtained by reading the data memory.
Maintenance must be performed by a certified professional. You can often sign a maintenance contract when you buy an home battery solar system.
Technology and Functionality of Solar Home Battery Systems
You now know what an solar home battery systems is and why it is a useful addition to PV systems. At this point, let's delve a little deeper into the matter and clarify the question: How does a solar home battery systems work anyway?
The Basic Principle of Home Battery Solar System
With its produced electricity, your photovoltaic system first supplies your household and the devices active in it, for example freezers or refrigerators. Without a home battery solar system, the surplus energy normally flows into the public grid. With a home battery solar system, you can use the energy at a later time if needed.
Powerful Lithium Solar Battery Storage
In principle, solar home battery bank is nothing more than a large lithium battery or, more precisely, an accumulator. Accordingly, you can fill up and discharge your storage again and again. Only after many thousands of cycles and after a certain age the functionality of the accumulator decreases.
Structure of The Lithium Solar Battery
The most common types of storage batteries are lead-acid and lithium-ion. In the main, they differ in the materials used. In the basic structure, however, they are the same: Two rod-shaped conductors (the electrodes) are located in a conductive liquid (the electrolyte). During charging and discharging, charged particles (the electrons) move from one electrode to the other. When the electrical energy reaches the battery, it is converted into chemical energy. In this way, it can be stored - at least for a few minutes to hours.
Economic Efficiency of an Home Battery Solar System
It is rare for an home battery solar system to be fully charged. This means that lithium solar battery usually operate at partial load and do not use their full capacity. How economical an home battery solar system is therefore depends on its low-load behavior - i.e. how the home battery solar system works when little electricity is used in the household. This is because lithium solar batteries cannot store energy forever. Under certain circumstances, the energy "expires," so to speak.
Capacity and Performance Should Match
Large home battery backup power supply with high storage capacity but low charging power, for example, tend to be less economical. On the one hand, it takes a long time to fully charge them. On the other hand, they can only deliver low power when demand is high.
Therefore, the storage capacity and the charging power should be approximately identical. Otherwise, the battery cannot work efficiently and takes too long to recharge.
Self-consumption Instead of Feeding Into The Grid
You should keep in mind: The electricity from your photovoltaic system is much cheaper than the electricity from the public energy grid. It is therefore advisable that you use as much of your solar power as possible yourself. A home battery backup system can help you to maximize the solar energy share of your electricity consumption. Per se, even a low-capacity storage system is therefore a plus for the economic efficiency of your PV system - and is worthwhile for financial reasons alone.
If you can only install a small home battery backup system for the time being, that is not a big deal. With BSLBATT Powerwall batteries, you can easily add, expand or replace lithium solar batteries at a later time.
What You Should Know About The Lithium Solar Home Battery Bank
The functioning of an lithium solar home battery bank is sober science and not witchcraft. Nevertheless, technical details and relationships can sometimes be difficult to understand - especially if you're not particularly tech-savvy, let alone well-versed in the fields of physics and chemistry. To help you find your way through the jungle of technical terms, we would like to explain the most important terms related to solar power storage.
Important Terms Around The Lithium Solar Home Battery Bank
The longer a lithium solar home battery bank is in use, the more it pays for itself. As with all technical devices, each of the components can wear out over time. However, what really determines the functionality of the lithium solar home battery bank is the lifespan. Depending on the model and manufacturer, it can be 5 to 15 years，BSLBATT Powerwall battery can provide ≥ 10 years of life, and our technology is still being updated, and the future is more than that.
Relationship Between Charge Cycles, Depth of Discharge and Service Life
How long your lithium solar home battery bank lasts is influenced by the depth of discharge, the charging speed and the number of charge and discharge cycles. Each model behaves differently. To help you understand the lithium manufacturer's specifications for handling your solar battery storage, you should be familiar with the following two terms:
DoD (Depth of Discharge): This value describes the depth of discharge (also known as the degree of discharge) of your lithium solar home battery bank. A DoD value of 100 % means that the lithium solar home battery bank is completely empty. 0 %, on the other hand, means that the lithium solar battery is full.
SoC (State of Charge): The SoC value, which reflects the state of charge, is the other way around. Here, 100 % means that the lithium solar home battery bank is full. 0 % corresponds to an empty lithium solar home battery bank.
Depth of Discharge of an Solar Home Battery Bank
How is this information relevant to the lifetime of your solar home battery bank? Here is an example: In the lithium battery manufacturer's data sheet, the service life of the solar home battery bank is specified as 10,000 cycles at 80 % DoD. This means that the solar home battery bank should not exceed the DoD limit of 80 %. It must therefore never be completely discharged and should always have a residual charge of 20 %. This is the only way it can achieve its service life of 10,000 cycles. For example, if the Powerwall battery has a gross storage capacity of 5 kWh, only 4 kWh can be used in practice.
AVOID DEEP DISCHARGE AT ALL COSTS
On average, you should remove a maximum of 50 to 90 % of the stored energy in a discharge process. If the depth of discharge falls below that specified by the lithiuim battery manufacturer, deep discharge occurs. This can damage the battery and reduce its service life. However, the battery management system ensures that this does not happen.
By the way, you don't have to worry that the solar home battery bank will simply run out of power after the specified number of cycles: The solar home battery bank will still function after the specified number of cycles, but its capacity will only decrease.
In addition, the type of solar home battery bank or the material used also plays a role: This is subject to natural aging processes, which are indicated by the calendar service life.
Efficiency - how efficient the storage is?
You may have heard the term "efficiency" before, for example in connection with motors. In general, the efficiency indicates how efficiently a device converts or uses the supplied energy. In the case of electricity storage, the efficiency refers specifically to the question: How much of the electricity fed in from the PV system can actually be withdrawn afterwards?
This is because a certain amount of the energy fed in is de facto lost during the storage process. Strictly speaking, the energy is not lost, keyword "law of conservation of energy". However, it is converted into heat during storage and is therefore no longer available to you as electricity. Across the board, the efficiency of lithiuim solar battery storage systems is between 70 % and 95 %. However, it is important to distinguish between the efficiency of the lithium solar battery and the overall efficiency of the entire home battery solar system.
There is also the system efficiency. This is the total of all the efficiencies relevant to your PV system. In addition to the efficiency of the home battery storage system, this also includes the efficiency of the photovoltaic system itself, for example. After its conversion, the solar power passes through various stations (e.g. solar modules, cabling, inverters). Losses also occur in the process.
Everyone wants a PV system as well as an electricity storage system with high efficiency. Therefore, the efficiency is in many cases a decisive purchase argument. However, it is essential to pay attention to which of the efficiencies described above the respective information refers to!
C-rate Referred to as Power Factor
Another important specification is the so-called C-rate, also known as the C-coefficient. The C-rate reflects the discharge capacity and the maximum charge capacity of your home battery backup. In other words, it indicates how quickly the home battery backup is discharged and recharged in relation to its capacity.
How to understand the C-rate?
A coefficient of 1C means: the lithium solar battery can be completely charged or discharged within one hour. A lower C-rate represents a longer duration. If the C coefficient is greater than 1, the lithium solar battery needs less than one hour.
With the help of this information, you can compare home battery solar systems and reliably plan for peak loads (for example, from energy-intensive household appliances such as washing machines and dryers).
Self-sufficient Energy Supply with Home Battery Storage System and PV System
What exactly does self-sufficiency mean in the context of photovoltaics? And how can you achieve it?
One 100 % Independence is Rare
Self-sufficiency in power supply means that you make yourself independent of the public grid. The more self-sufficient you are in supplying your household, the more electricity you get from your PV system and the less from the usual energy suppliers. The ideal case is a degree of self-sufficiency of 100 %: You are then completely independent in terms of electricity. In practice, however, it is hardly possible for private households to achieve this degree.
Difficult technical and meteorological conditions
On the one hand, you would need a very large plant. And very few people have the space. On the other hand, it is not possible to predict exactly when you can expect how much solar energy. This depends on the weather, the amount of sunshine, and the time of day and year - factors that are unpredictable after a certain point.
Complete independence from the grid operator is therefore the exception rather than the rule. And so most of the private system operators continue to rely on obtaining part of their household electricity from the public power grid.
PV systems that achieve a degree of self-sufficiency of 100 % are also called "stand-alone systems" or "off-grid systems" - their independence is thus already in their name. You'll usually find the larger versions of such systems in remote locations, such as mountain huts. But there are also off-grid systems in "civilization". Namely, wherever only small amounts of electricity are needed and wiring would be too costly in relation: for example, parking meters or electric fences.
Life of Cycles - How Long the Lithium Solar Battery Lasts?
You've probably come across the term "cycle" in other contexts as well. The word comes from the Latin "cyclus", which means nothing other than "circle". In the case of electricity storage, a cycle refers to a process of charging, storing and discharging energy. Lithium solar battery manufacturers of home battery solar systems and rechargeable batteries indicate the estimated service life of the respective device by means of the number of possible cycles - the so-called cycle number.
Strictly speaking, this refers to full cycles. This means that the full capacity of the battery is used when charging and that the battery is emptied to the maximum depth of discharge when drawing energy. However, this is a very theoretical scenario. In practice or in everyday use of the home battery backup systems, full cycles rarely occur. Often, the lithium solar batteries are not fully utilized and only partial cycles occur. These only correspond to a certain proportion of the possible full cycles. A solar home battery bank therefore normally manages more partial cycles than the full cycles specified by the lithium solar manufacturer (the service life of modern devices is around 5,000 to 10,000 cycles).
The number of cycles is not the only factor that affects the life of your Lithium home solar battery. Even when the battery storage unit is not in use, the battery ages. This is quite natural, which is why you cannot avoid replacing the battery after 15 to 20 years at the latest.
Storage Capacity - How Much The Solar Home Battery Can Store?
Storage capacity simply describes how much energy your home battery backup systems can store. While the efficiency and number of cycles can be described as "the higher, the better", the storage capacity is a bit more complicated. This is because the optimal storage capacity depends entirely on your individual situation and the electricity consumption in your household.
In short, this requires careful consideration. The capacity of your storage should be large enough to supply your household with electricity from sunset to sunrise. At the same time, you want to avoid unnecessary additional costs and collect as much of the feed-in tariff as possible. If the storage capacity is too small, it cannot store enough energy for the night. Then you have to buy expensive electricity from the public grid. For example, you need 300 kilowatt hours (kWh) more electricity each month than your home battery solar system can supply. At an electricity price of 30 cents per kWh, that's 90 dollars in avoidable additional costs.
TAs a rough guide, an average four-person household consumes about 4,500 kWh of electricity annually. An appropriate size for the lithium solar battery in such a case is 4 to 7 kWh.
Combination of PV System and Home Battery Storage System
Nevertheless, a photovoltaic system makes a huge difference. Even a self-sufficiency level of 30 % makes a significant difference, both financially and in terms of climate.
Achieve Maximum Self-sufficiency
With a more powerful system, you can achieve even more. And with an home battery solar system, you can make your power supply as self-sufficient as possible: With home battery solar system, 30 % quickly becomes 50 %.
Because the aforementioned unpredictability of weather and the like is then hardly a problem. Because the home battery solar system has saved electricity from "better times", it can easily bridge such energy deficits. This makes you even less dependent on the public power grid. At the same time, your household always has enough energy available - and can rely on a stable supply.
Self-sufficient From the Start
As a rule, you can equip your photovoltaic system with an home battery storage system at a later date. However, in the case of new systems, it is worth planning with a home battery storage system from the outset. In this way, the system and the lithium solar battery can be optimally matched to each other. In addition, the installation costs are lower - after all, the installation company only has to come once.
And you also have a decisive advantage in terms of self-sufficiency: with home battery storage system, you can use your PV system as efficiently and environmentally friendly as possible from day one.
The electricity demand of your household is first covered by solar energy. Only when the power from your PV system is no longer sufficient, you draw energy from the public grid. You can therefore further increase your degree of self-sufficiency by reducing your electricity consumption with home battery storage system. For example, pay attention to your individual user behavior and preferably use energy-saving devices.
Why Home Battery Solar System is Good for The Climate and The Environment?
Instead of relying on fossil fuels, a photovoltaic system relies on the energy of the sun. Unlike finite resources such as oil, coal and gas, solar power will be available to us for another few billion years. A PV system alone is therefore a huge plus for your personal environmental balance. And with a lithium solar battery, you can improve your ecological footprint even further.
Save CO2 thanks to Electricity Storage Unit
Your home battery storage system keeps the electricity from your PV system until you need it. This allows you to exploit the full potential of your system - and reduce your energy requirements from the public grid to a minimum.
In addition, home battery backup systems can help reduce your CO2 emissions. However, the choice of device plays a crucial role here. Because even if solar power (and its home solar battery) is more or less CO2-free, the production of the home battery backup system still produces emissions. So it's important that you choose an efficient model. They can save up to 35 kilograms of CO2 a year and make up for their production emissions.
A truly sustainable home battery backup system with CO2-saving potential meets the following requirements:
It has low losses during charging, power delivery and standby mode.
It achieves an efficiency of over 95 percent during both charging and discharging.
Home Battery Solar System Supports the Energy Transition
The fact that something has to change in the way we use energy is becoming increasingly clear against the backdrop of climate change. Photovoltaics can make a decisive contribution to the urgently needed energy turnaround. Nevertheless, its triumphant progress is rather slow. One of the main reasons: Like wind power, photovoltaics supply energy irregularly.
With an home battery storage system, you can bring regularity to your solar energy supply, so to speak. This is because the home battery storage system also provides you with PV power when your solar system is not producing enough energy. In this way, you help to bring renewable energies such as solar power to the forefront and establish them as a viable supply alternative.
Advantages of an Electricity Storage System
If you have read this page carefully, you should now be clear: a home solar storage system is a worthwhile and sensible addition to any photovoltaic system. To make this clear again, we have summarized the three main advantages of solar power storage batteries.
You increase your own consumption and lower your electricity costs Without solar home battery, your surplus PV energy goes into the power grid. At times when there is little sunshine, on the other hand, you have to buy electricity from the public grid. Since the feed-in tariff falls and the electricity prices rise, this calculation does not work in your favor.
With solar home battery, you can use the maximum of your solar power yourself. This will improve your environmental balance and enjoy a lower electricity bill.
You make yourself independent of the public energy supply A PV system alone makes the power supply of your household a lot more self-sufficient. However, home battery backup power supply significantly improve your degree of independence. This is not only a benefit from a financial or air conditioning point of view: You can be sure that your electricity is really green and you don't have to worry about fluctuating energy prices.
You are doing something for the climate and the environment A considerable part of the world's electricity still comes from non-renewable energy sources. The generation of energy from fossil fuels produces the climate-damaging greenhouse gas CO2 - the main cause of global warming according to the current state of the science.
Photovoltaics, on the other hand, use the sun's energy to generate electricity. The more solar power you use, the more you improve your own carbon footprint. Home batteries for solar will help you with this. Since the devices are designed for a long service life of 5 to 15 years, replacement is rarely necessary - another clear plus for the environment.
