This charges 12 or 24 volt batteries. Power can be used as DC or converted to AC power. Greater nozzle pressure and larger volume of water onto the wheel from more downhill fall produces more power. Sites with more down hill fall are more desirable. They need less water, use smaller pipe, cost less to install, and fare better in dry years.
Solar cells convert sunlight to electricity within wafer thin cells.
This a very intelligent alternative to high-cost electricity. Siemens residential power modules use quality single crystal cells grown in a cylindrical crystal. For savings, these cells are not trimmed square to fit tightly in the module, but are left rounded for less waste of cell material and larger cells. Each module has a 10 yr. factory warranty. Power inverters convert DC from your battery to 120 volt AC household power to use AC lights, outlets and appliances anytime, without starting a generator.
