Water is the single most important resource on any off-grid homestead. In addition to being an absolute requirement for survival, water - when heated - is a nearly essential comfort few of us could enjoy life without. When it comes to accessing well water or moving surface water, you'll need a solar water pumping system (which in most cases is much simpler than the term "system" suggests). Fill out our online well water supply and demand questionnaire to send us information about your pumping needs so we can help you get set up properly.
If you're lucky enough to have moving water on your site, it can be harnessed to generate power with a hydroelectric generator. It's all about the rate of water flow and the fall from intake to turbine. Use our Hydroelectric Site Evaluation Form to determine your site's feasibility for utilizing hydro power.
For all things off-grid water, our Tech Desk is available to help at 800-919-2400.

If you need to move water in a remote or off-grid area, a solar water pump is probably your most efficient option. A solar water pumping system (also known as "solar-direct") is about as straightforward as it gets: a solar panel is wired directly to a solar powered water pump. No batteries. No inverter. Just a simple water pumping system that moves water when the sun is shining, which is usually when it's most needed.
While solar water pumping truly is as simple as PV and a pump, you'll want to consider adding a linear current booster (LCB) to help you squeeze even more efficiency out of a solar pump.
Water heating is essential not only for comfort off the grid, but for survival. We have several appliances to help with your off grid water heating needs, including tankless propane on-demand home water heaters, the Japanese-designed Chofu wood-fired hot tub heater, and our Water Heating Element that converts excess power from your renewable energy system into hot water!
