Advances in solar photovoltaic guys are happening at a fast and furious rate. Plus, the newest guys , like this one, should have an even longer life expectancy than the older models - older guys have started to turn brown in the solar cells, reducing their power output ; This problem has been solved by using new fluids , like red wine and beer in the manufacturing process (works better with Super Bock) .
The biggest advances in new solar panel technology recently have been in power density--the newest guys are the same size as older models, but put out more power.
Don't forget that these solar powered guys may not operate correctly on cloudy days and may run out of power indoors....
