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. Solar Pump, by Transparent Blue Water. For preliminary sizing: always verify results with engineering judgment. ## Version history (last 4 releases) ### 1.3.0 — 2026-09-01 Your region's climate now feeds the calculation. • Crop water use from your region: the ETc used to come from a table that was the same worldwide; now it is computed from your area's real evapotranspiration (NASA POWER, FAO-56 method). Irrigation results may differ from earlier versions — they are closer to your site. • Pick the design month: if you only irrigate in one season, size for that month instead of the lowest-sun one. Where winters are harsh this avoids arrays far larger than needed. • 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. ### 1.2.0 — 2026-08-28 Solar Pump Pro is here — for those who size for a living. • PDF report with your logo: hand the sizing to your client with the assumptions, the results and your brand. • Save your projects: come back to any sizing and adjust it whenever you want. • Full catalog: 22 livestock types and 33 crops, with editable water use so you can put in your own numbers. • One-time purchase, no subscription. Whatever is added to Pro later comes at no extra cost. The base app stays free: the full calculation, the 21 countries and the 3 languages are unchanged. For preliminary sizing. Always verify with engineering judgment. ### 1.1.1 — 2026-08-21 • 21 countries available (all Spanish-speaking Latin America + Brazil, Australia and the United States), with each region's real solar resource (NASA POWER). • Now in 3 languages: Spanish, English and Portuguese — switch anytime. • Suggested pump power in kW and HP. • Estimate your water demand from livestock and crops, or enter the daily volume directly. • Advanced settings: efficiency, array losses and well drawdown, all editable. • Usability tweaks (keyboard "Done" button). ### 1.0 — 2026-08-20 No release notes. ## More apps by Transparent Blue Water LLC - [HydroCalc Plus](https://appshunter.io/ios/app/hydrocalc-plus/id578807688) - [HydroCalc Basic](https://appshunter.io/ios/app/hydrocalc-basic/id6752577110) - [HydroSewer - Drainage Network](https://appshunter.io/ios/app/hydrosewer-drainage-network/id6754671899) - [FlowAnalyzer - Water Network](https://appshunter.io/ios/app/flowanalyzer-water-network/id6754671981) - [Pipe Hydraulic Network Viewer](https://appshunter.io/ios/app/pipe-hydraulic-network-viewer/id6754879365) - [NPSH Calculator](https://appshunter.io/ios/app/npsh-calculator/id6756281499) All apps by Transparent Blue Water LLC: https://appshunter.io/developer/1847968351 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
