About Agricultural Solar Energy & Solar Irrigation Pump Calculator
Calculate solar photovoltaic (PV) generation potential for farms, greenhouses, and rural homesteads. Sizes rooftop or ground-mount solar arrays, calculates daily and annual kilowatt-hour (kWh) yield based on Peak Sun Hours (PSH), determines solar pump capacity, and projects financial grid-offset savings.
Key Capabilities & Features
- Solar array capacity sizing (kWp) based on daily electricity demand and Peak Sun Hours (PSH)
- Solar irrigation pump sizing engine matching hydraulic pump horsepower (HP) with required PV wattage
- System derate factor modeling (dust, temperature coefficient, inverter efficiency)
- Annual clean energy output (kWh), grid electricity savings, and carbon emissions avoided

Frequently Asked Questions
How many watts of solar panels are needed for a 5 HP agricultural water pump?
A 5 HP pump draws approximately 3.73 kW of continuous electrical power. Factoring pump motor startup surge and inverter derating, a 5 kW to 6 kW peak solar array is typically recommended.
