We are down here in our basement. It's not
very comfortable but we need the space because
here, what you see there, is our golf car
batteries. You can use different kind of batteries.
There are much more sophisticated ones, but
they are much more expensive so we choose
just to get golf car batteries. Some of them
are even recycled from someone who didn't
need it any more. One of these batteries is
about fifty-five dollars. Why do we use golf
car batteries? A golf car battery is a deep
cycle battery. That means it can store a lot
of energy but it's not able to give it away
in a short moment. In a car you have a battery
that needs full power when you turn around
your key. In a golf car battery you want to
have a battery that you can drive for a long
time. The same idea we have here because we
want to store the electricity we get for as
long as possible because we never know when
the sun is shining or when the wind is blowing.
That's kind of a huge storage and the more
batteries you have the more storage you have.
