make or convert water pump to solar power. How to do it?
All systems will run on the same setup, but the size depends on the wattage of the pump (sometimes expressed in horsepower which is directly compatable with watts), and how long you run the pump each day. Multiply watts by hours and you get watt-hours (a measure of stored energy). Now you know your needs, you need to build a system to run it. It needs Solar collectors, charge controller(s), timer(s), and batteries with enough capacity to charge/run the system. Lastly if the pump is AC you need an inverter to convert the DC battery power to AC usable electricty. Panels are rated in Watts, and you can check your local government surveys for how many hours of sun you get per day – Now divide your energy required (watt-hours) by average hours of sun, and you get total watts of panels required. You will want padding on this amount as its not always 100% maximum sunny during the sunny hours of a day. Lastly you need to build the battery/inverter system. Hook up the panels to the batteries th
