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.

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.

• 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).
