The optimal solar panel tilt angle equals your latitude, facing true south (Northern Hemisphere) or true north (Southern Hemisphere). At 40° latitude (New York), set panels to 40° tilt.
A solar water pump sizing calculator is an online tool that estimates: Pump power (Watts) → how much energy your pump needs. Battery capacity (Amp-hours) → storage needed to keep water flowing during cloudy days.
Solar panels turn sunlight into electricity but aren't as efficient as we'd like. Cloud cover can significantly decrease the efficiency of solar panels. On a sunny day, they produce only about.
