[Greenbuilding] Self-Contained Solar Units

[Clarke Olsen]

Not common, but it does happen: lead acid batteries can explode. Happened to me a few months ago: I charged a car battery, 
not realizing that a lot of liquid had been replaced by hydrogen gas. With no hood, pieces flew car lengths in all directions!

They require maintenance, at least in the sense that they don't like being discharged all the way, and you have to keep an eye on what is going on with the charge/discharge cycles. The Tesla system uses lithium ion batteries, the same as in their cars. They are actually a whole bunch of small 18650 cells, which are also used in all the power tool batteries, laptops, etc., and is where the R&D money is going. They are more expensive, but don't care about being at partial charge, etc., and much more user friendly and longer lasting.
