Small-scale Off grid Solar PV: Installation Manual

A PV system is a great advantage over high energy costs.. My complaint is about the cost of replacing the lead-acid batteries.. Most lead-acid batteries have a projected life span of approx. five years... Where does the money come from for replacement when the time comes?.. A huge burden on poor people...
