Here’s a look at the components that went into our off-grid strawbale dispensing location in Pittsboro, NC.

Solar Panel: Used from Ebay. We bought a 20 watt BP/Solarex panels for $90 with mounting brackets. A new 20 watt panel will run about $180 without a mounting bracket. A 10 watt panel is about $90, so it is important to know how much you will be pumping to size appropriately.

Mounting Bracket approximately $40 new.
