When is a charge controller needed ?
I haven't found cheap/free 2nd hand solar panels yet, but thanks to Gascort I'm thinking about building my own... then I'm imagining where to put put these cells and so how to design the shape of the panels...
One question I have : when is a charge controller needed ?
My current cases are :
I think that in both cases, the panels are too weak to damage the 50Ah 12V batteries. From which wattage does a charge controller is needed ?
Earth absorbs 1.8 t CO2/head/yr, while a French generates 6.2 t CO2/yr
