TIPS
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.
