The elevation of the installation site can significantly affect the performance of a solar pump. As the elevation increases, the atmospheric pressure decreases, resulting in a decrease in the boiling point of water. This can cause the pump to work less efficiently, as the lower boiling point can lead to the formation of air bubbles in the system, reducing its pumping capacity. Additionally, higher elevations may also lead to a decrease in sunlight intensity, reducing the solar pump's overall power output. Therefore, careful consideration of the installation site's elevation is essential to ensure optimal performance of a solar pump.
