Easy Solar Sizer vs Solar Pump

SolarSize helps you estimate the solar panels, inverter and battery you may need for water pumps, farms, container homes, rural houses, small shops and security cameras. Choose your location and use case, get simple offline results, panel direction, tilt guidance and clear safety warnings. No login, no subscription, no internet needed.

Solar Pump sizes battery-less solar pumping systems (direct to tank), built for the field. Tell it how much water you need and the head, and it computes the solar array size and the pump class — no need to know panels or electricity. WORKS OFFLINE All the math is local. No signal, no data needed — use it at the well, on the farm, anywhere. WHAT IT COMPUTES • The solar array needed (Wp / kW) • Suggested pump power in kW and HP • Design flow and pipe velocity • Total dynamic head (TDH) from your pipe and static head • The suggested pump class for your duty point • Daily system energy SIZED FOR THE WORST MONTH The system is sized on the peak sun hours of your region's lowest-radiation month, so it delivers water year-round — even in the cloudiest season. ESTIMATE YOUR WATER DEMAND Not sure of your m³/day? The app estimates it for you: • Livestock: dairy and beef cattle, pigs, poultry, sheep and goats, and more • Crops: by area and irrigation method (drip, sprinkler, furrow) Or enter the daily volume directly. 21 COUNTRIES, 3 LANGUAGES Available across all of Latin America plus Brazil, Australia and the United States — 21 countries, each with its region's real solar resource (NASA POWER, 20-year climatology). Switch between English, Spanish and Portuguese anytime. ADVANCED SETTINGS Fine-tune the pump-and-motor efficiency, array losses (derate) and well drawdown to match your case.
