Solar water pump systems are perfect for swimming pools, or reservoirs like those used for livestock and agriculture. They operate during the daytime, and turn on automatically once there is enough sunlight. Because solar water pumps are independent of a utility grid, they're a perfect solution for isolated rural locations.

NREL Solar Pump Cost Comparison
The U.S. National Renewable Energy Laboratory (NREL) has developed a sophisticated simulation program that optimizes the most economic energy choices per specific project inputs. In this example, NREL has used HOMER (Hybrid Optimization Model for Electric Renewables) to model choices for a pumping system that is designed to pump 5,000 gallons per day from a total depth (head) of around 100 feet. It compares a solar array of 1900 watts against a 4 kW diesel generator. Both power an equivalent pump of approximately 1 horsepower.
The table below shows the cost comparison over a lifetime of 20 years.
