About Residential Battery Backup Power Systems:

The residential energy storage system is a smart solution that can store the power of the solar panel on the battery for you to use when you need it at home!

The natural combination of solar energy and battery energy storage systems brings huge economic and environmental benefits. This is the perfect solution for homeowners who want true energy independence and control of electricity. Solar cell storage allows you to generate, store and manage your energy use. During a power outage, you have a reliable home power supply that allows you to control everything-you can choose the amount of power to back up. The battery system allows your solar system to take full advantage of changing electricity prices and monopolistic public utility policies to add value and energy security to your home.

In the past few years, residential energy storage devices have increased dramatically, exceeding 200% per year-and are expected to continue to grow rapidly. Many users have seen the huge benefits of using solar energy, especially in some areas with unreliable power grids, where the electricity generated by solar panels is sufficient for them to survive the power outage, and the increase in the probability of bad weather has promoted more Many families have demand for residential energy storage batteries.

Technology based on lithium-ion batteries is advancing, so the cost of lithium-ion batteries used in energy storage batteries is also falling. From 2015 to 2021, the cost per kilowatt-hour of residential energy storage has been reduced by more than 15% every year. For families who have not yet installed residential energy storage batteries, it has also greatly increased their enthusiasm for renewable energy!

In general, residential energy storage batteries not only reduce the risk of power outages and other problems, but also reduce environmental carbon pollution, and also greatly reduce the cost of electricity for users.

Residential energy storage also plays an important role in smart home systems. New residential energy solutions will be launched soon to meet the broader needs of the power sector for decarbonization, the use of decentralized renewable energy, and the continued electrification of transportation. Smart homes have the potential to completely change the way people interact with their homes. Energy storage systems can help smart home systems to better manage household appliances and make people's lives more modern and intelligent.

Why Choose Solar Panels + Residential Battery?

Although solar panels can reduce your investment in the grid to a certain extent, they cannot store excess solar power. Therefore, choosing a residential battery energy storage system can reduce your use of the grid to a greater extent. , The combination of solar energy and energy storage system can turn your house into a micro-grid, which can achieve self-sufficiency in electricity for a short time!

Solar energy and residential energy storage are business opportunities for each other. As solar penetration rates increase, states and solar companies are turning to energy storage batteries. Residential energy storage can use arbitrage to stabilize electricity prices, manage evening energy slopes, reduce the risk of power curtailment, provide black start capabilities, and provide backup power.

As the manufacturing industry expands to support grid applications and electric vehicles, the cost of lithium-ion batteries (the most common type of storage paired with solar energy) has dropped rapidly. Smart residential energy storage systems launched by more companies can help users allocate solar energy storage power to the greatest extent and enable system owners to use solar panel power for more hours of the day.

Many solar companies see storage as an opportunity for business growth. Although standalone solar definitely has a lot of room for growth in most states, the long-term success of the solar industry and its ability to expand to more than 20% of total power generation depends on cost-effective storage integration.

If you have solar panels or are looking to install solar panels, you want to make the most of your energy system. Installing a home backup battery system for the excess power generated by the battery panels is a good way to improve the all-day performance of the power generation system. The following are the main benefits of residential energy storage batteries.

Self-use of Solar Energy-For homeowners, self-use of solar energy is the most important application of residential energy storage systems. Energy storage allows homeowners to store excess energy generated by solar panels during the day and use it at night. For some utility customers who do not provide net metering, this may be a good choice.

Off-grid-solar Off-grid households need energy storage batteries. Modern battery energy storage systems far exceed the capabilities of marine lead-acid batteries used by pioneers of solar DIY in the past few decades. Modern systems are easier to install, easier to configure, more scalable, cheaper to store per kilowatt hour, and more secure.

Emergency Backup-Residential battery energy storage provides peace of mind to keep the power on during a power outage. Regardless of whether solar energy is used, energy storage can safely and seamlessly replace small generators, which are one of the main causes of carbon monoxide poisoning in the United States.

Residential Energy Storage and Grid

According to EIA's international energy statistics, in 1990, the total amount of solar power generation in 11 countries was about 400 million kWh. In 2019, 218 countries and the US territories generated about 699 billion kWh. The top five producers of solar power generation in 2019 and their percentages in the world's total solar power generation are:


United States-15%

Japan – 11%

India –7%

Germany –6%

In the first quarter of 2021, 281.5 MW was installed in the US energy storage market, an increase of 115% over the first quarter of 2020. In terms of FTM deployment in 2021, the first quarter is expected to be the smallest quarter. This is an unprecedented year, with many planned storage projects in multiple states coming online. The increase in energy storage in the US energy storage market in 2025 will be five times the increase in 2020, and FTM energy storage will continue to contribute 75-85% of the new MW each year.

The scale of residential energy storage is also taking up an increasing share of the energy storage market. Although some households use solar systems to generate electricity every day, they may not necessarily use the electricity stored in the battery every day, or they can’t use it up at all. The entire amount of electricity in the home’s energy storage battery. Therefore, more and more people are considering how to make residential energy storage to help local utility companies make the grid more cost-effective, reliable, resilient and safe.

Power grids in many regions are under increasing pressure. Grid assets are aging. Intermittent sources of renewable energy generate more and more electricity and require more load balancing. The incidence of severe weather is rising. These trends are exacerbating bottlenecks and congestion points in the energy delivery system, leading to rising costs and potentially increasing the probability of local power outages.

Instead, the increasing number of residential energy storage is a breakthrough in establishing public utility companies. In some states in the United States, pilot programs have been launched to allow utility companies to pay households equipped with batteries to use part of their stored electricity when the system is under pressure. Home and small business photovoltaics are not part of the power distribution system, but are basically indoors, where large amounts of electricity are used, some may be output to the system through meters, which initially measure the electricity extracted from the grid for charging. On the one hand, the electricity feedback of residential energy storage to the grid can alleviate the electrical power of the grid, but it also benefits these enthusiasts who like to use renewable energy and reduces their economic expenditure on home solar storage systems. Let public utility companies and individual users benefit from it!
