Pump performance curves show gallons per minute at specific head levels. Multiplying expected flow by usable sun hours gives a realistic estimate of daily water production. For a detailed explanation of calculating lift and selecting equipment, see the solar pump sizing guide. Peak sun hours (also known as solar insolation) refers to the average equivalent hours of full sun energy received per day. averages 5-6 peak hours in the summer, and dips to as low as 3-4 peak. Note: This calculator provides estimates based on typical values. Total Dynamic Head (Depth) Total vertical distance from water level to storage tank. Surface pumps can draw water from 20-25 ft (7-8 m) below ground level, geographic location and season. For example, the arid. matter experts, we created a resource to support the efforts of those working to fill this gap.
