I am looking into buying a portable solar charger for my laptop, but can't find any information on how long these products are supposed to last. I know thin film panels usually only have warranties for 5-10 years in normal solar panels (versus longer lifespans with the crystalline panels). ...

What is the amount of solar energy required to drive a 250 pound cart with a 250 pound person 10 miles? How many square feet of recharged paneling would be required?
If you are willing to go slowly enough, all you need from the solar panel is enough to overcome static ...

I have an ~18v solar panel and a ~15v wind turbine. Sometimes one generates more voltage than the other. How would I get both of them to charge one ~12v battery? I can't just connect them in parallel with diodes, because in that case, only the higher voltage source gets ...
