To calculate the required solar panel capacity for a solar pump system, you need to consider the power requirements of the pump, the average sunlight hours in your location, and any additional energy losses. Firstly, determine the power consumption of the pump in watts. Then, calculate the daily energy requirement by multiplying the pump's power consumption by the number of hours it operates daily. Next, divide this daily energy requirement by the average sunlight hours to obtain the minimum solar panel capacity needed to meet the pump's demand. Finally, account for any energy losses due to factors like inefficiencies or shading to ensure you have sufficient solar panel capacity to operate the pump efficiently.
