For light-duty use, such as charging phones, LED lights, or a small fan, a 100W to 150W solar panel is often enough for a 12V 50Ah or 100Ah battery.

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.

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.

To charge a 150AH battery in about 6 hours, you need around 450 watts of solar panels. This estimate assumes 15% efficiency. Always factor in these elements for accurate calculations.
