We have a well- 350 ft deep , the pump is at 240 ft deep and casing is 105 ft. We live at the top of a fairly lrg hill. We are currently 100% electric. We have propane as a backup energy for heat and generator. So far what we have looked at is looking like it will cost $1500-$2000 +when we figure in the costs of pipe and all the misc equipment. We considered a cistern system but dh says with our location so high (house is at very top of hill) that it won't work. We have also considered using solar cells with a battery and using an inverter but it seems from dh's study that it wouldn't necessarily work for the well if converting from DC to AC 220-240v. Does anyone else have ideas on how to do this? Things we have overlooked or cheaper sources for material? Our generator is powerful enough to power the pump but we would like a backup plan that doesn't rely on fuel. thanks in advance !
