Despite the lower flow rate compared to AC pump and diesel pump, solar pump can operate every day for an average of 8 hours without the need of electricity power supply or diesel.

The three factors to consider when choosing a solar pump package:

1)How much water is needed per day? (On average, we estimated 40-50 litre of water per head per day would be sufficient).

2)What is vertical distance from the water standing level to the top of the tank? How much lift is required to pump up to the tank?

3)What is the total distance from the bore or dam to the water tank? If the distance is more than 1000m, pipe friction loss must be accounted for to calculate total head called Dynamic head (TDH).

Example: A farm in rural Australia has 50 heads of cattle and is looking for a solar bore pump to supply enough water for the cattle. The vertical lift from the water level to the top of the tank is 40m and the tank is within 1000m from the bore.

200 heads of cattle require about 10,000L of water per day and the vertical lift is about 40m. The distance between bore and tank is less than 1000m therefore friction loss due to long pipe distance is negligible. On average, there is 8 hours of sunlight per day to operate the solar pump, but there should be more than 10 hours of sunlight during most of summer season.

10000L / 8hrs = 1250L/h= 20.8L/min

The farm would need to look for a solar pump package that can pump approximately at least 5.2L/min at 40m total head. For this application, we would recommend our Tuhorse 3”500W solar pump with 4 solar panels which would pump up to 24L/min at 40m total head.
