My solar panel is putting out more energy than my batteries can hold on a sunny day. I had to add more batteries to increase the capacity. That also means more possible energy use for me at night.

I now have five 10 Amp Hour batteries hooked up. That equals about 600 watts of total energy capacity. Theoretically, I could run my netbook for 15 hours on a full charge. Of course, it is winter now and the sun doesnt shine all the time so I will never reach that capacity. But in the summer, I will probably have more energy than I could use.

My living room light and my aquarium are now running full time on solar energy.
