4.4 Modelled performance – including the well pump<br />
General results from the model<br />
Annual energy available from PV 8820 kWh/y<br />
Annual hours run 2357 h/y<br />
Average hours run per day 6.46 h/d<br />
Annual water production 960 m 3 /y<br />
Average daily water production 2.63 m 3 /d<br />
Overall annual average specific energy 8820/960 = 9.19 kWh/m 3<br />
The annual energy available from the PV (8820 kWh/y) is unaffected by the addition of the well pump to the model. But, a<br />
considerable proportion of this energy is now used by the well pump, and so the annual water production predicted by the model is<br />
reduced from 1200 m 3 /y to 960 m 3 /y. This is reflected in the substantial increase in the overall specific energy, from 7.35 kWh/m 3 to<br />
9.19 kWh/m 3 .<br />
