Based on our calculations and real-world conditions, you would need approximately 18 solar panels, each rated at 300 watts, to sufficiently power your well pump while accounting for various efficiency losses. Understanding the energy needs of your water pump is critical.

The distance between two rows of solar panels should be five to six inches. It is also recommended that you leave 1 to 3 feet of space between every second or third row.

A standard 1 HP (horsepower) water pump typically requires between 800 to 1200 watts of solar panels. This usually translates to three 400W panels or twelve 100W panels. The exact number depends on the pump type (AC or DC), its efficiency, and your location's sunlight conditions.

A range from 100 to 400 watts is generally considered appropriate for outdoor solar panels, depending on energy needs, location, and panel efficiency. Ideal wattage provides a balance between sufficient energy production and manageable installation and cost considerations.
