About this app

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.

What’s new

Your region's climate now feeds the calculation.
• Crop water use from your region: now it is computed from your area's real evapotranspiration (NASA POWER, FAO-56 method).
• Pick the design month: if you only irrigate in one season, size for that month instead of the lowest-sun one. .
• The PDF report now states which month the system was sized for and which evapotranspiration was used.
• The PDF is saved with a recognizable name, ready to send to your client.
