Lead acid battery are the most common form for solar battery
storage currently on the market.
Battle-tested, thousands of the world's people have used large of lead-acid batteries with solar electricity to
remove their need to be
connected to the traditional electricity grid.
The most common setup of lead acid batteries you'll see is usually
some kind of rural household installing a bank of batteries + solar
panels,
because it's cheaper than paying $30,000 to get the grid extended
all the way to their house.
However, some people who have normal access to the grid still elect
to go off-grid with a big bank of lead acid batteries.
