So looking to take my current well pump and want it to make it more reliable! I want to make it solar or wind power. We don't use a lot of water from from our well or we don't think we do less then 500 gallon a day. I want to buy a 2,500 holding tank and pressure pump also solar or battery. I want to get the solar for the pumps because of the power goes out I'm not getting any water. Like to buy the solar and 2,500 holding tank but maybe on 2027?
Hello, I am a retired US Navy submariner. After I retired, we bought 150 acres in rural Maine. {.. horribly long and detailed story, redacted here for the sake of your sanity. ] I am almost off-grid with solar-power, I also have grid access, it is a matter of flip one set of breakers to be on-grid, or flip another set of breakers to be off-grid. The power grid in this area, is extremely unreliable. In the past 20 years we have not recorded a single 30-day month that did not include the grid going down. When it goes down, it might be down for two hours, or it might be down for two weeks. Tell us about your water supply. Are you going to be drilling? Do you have any idea of how deep you must drill to find water in that spot?
Check out Grundfos solar well pumps. I think there are cheaper brands but with something a critical as water and as expensive to replace you want to go with a good brand. The Grundfos pumps have built-in MPPT to run on solar, but will accept 90-250 vols AC. They will also run on 30 - 300 volts DC. In a pinch where you have little solar and no grid power, you can run the pump on a portable generator. I've run mine on an old 3200 watt Harbor Freight bottom of the line pipsqueak. On solar I power mine with a fixed, home made rack of 10 Kyocera 51 watt panels that were manufactured in 1992. Used panels, although they may not perform as well as they did when new, will do just fine if you have enough of them. They generate 150-180 volts DC at about 3 Amps in full sun. The pump was installed set at 580 feet at my remote property (no grid power within 20 miles or so) in 2014, and it's been as reliable as you can get. Only one time it didn't run, and I found a loose connection, five minute fix. They make other models for use in wells where the water table is higher so you don't need to get that particular one.
