How many watts is the efficiency of a solar circulation pump

How efficient is solar water pumping?

Zaky et al. (2020) proposed an efficient and cost-effective solar pumping system in a laboratory-scale model. The Solar Photovoltaic (SPV) water pumping systems test performance is achieved to maximum efficiency of 28–65 % for AC pumps and 8–60 % for DC pumps , .

How much water does a solar water pump use?

Similarly, the temperature variation recorded and used for simulation ranges from 15 °C (59 °F) to 40.5 °C (104.9 °F), and the quantity of water required is 36 lit/day for 1 acre of land. Fig. 8 shows the solar water pump performance for Theni district.

What is the efficiency of solar water pump in Kanchipuram?

The solar system efficiency obtained is 83.2 %, the pump efficiency 51.8 %, and the performance ratio 68.9 % for the average annual solar radiation of 5.85 kWh/m 2. Fig. 4. Solar water pump power performance analysis Kanchipuram.

What is the performance ratio of solar water pumping system?

The overall comparative performance of the solar water pumping system for the study region is presented in Table 7. The performance ratio of this research is 68.9 %, whereas, in another study, the performance ratio was reported as 54 % , and it is an efficient system compared to earlier studies.
