Solar Energy Storage

Unfortunately, the technology to use alternative storage sources is not as abundant as the readily available as nickel cadmium and lead acid batteries. However, I did see some other types of batteries. Here are two web pages(http://poweredbysolarpanels.com/solar-energy-storage/ , http://www.mpoweruk.com/zebra.htm ) that go into more detail about the technologies. I like the one called the Zebra battery, the only down side to using them is that they cannot handle being undercharge. So, I don’t think that it would work at night time and the best bet would be nickel cadmium or lead acid.
