Solar & Off-Grid

Solar pumping and off grid water guides for remote homes, farms, ranches, and boreholes far from the grid. Topics include solar submersible pumps, pump controllers, panel sizing, battery backup, generators, and payback calculations.

Solar pump sizing is unforgiving: too small and you get no water, too big and you waste money. These guides walk you through the calculations, with sun hours and units that work in any country.
