Solar Pump System Design.xmcd
Design a solar pump system for a 150 ft well located in Santa Maria, CA, which pums at least 1200 gallons per day. The worst month (December) insolation at the site is 4.9 Peak Sun Hours. (or 4.9 kWh/m
Use Jacussi SJ1C11 pump.
Use Siemens SR100 15-V PV Modules (rated current 5.9A)
(Q) Size the PV array for the pump system.

1. Required Pumping Rate (Qgpm):
gpm
2. Pump Power Input Calculation (Pw)
W
3. Number of 15-V 5.9-A PV modules.
4. Number of Parallel PV calculation.
5. Estimation of the actual water pumped
gpd
This is more than 1200 gpd required so the design meets the project goal.
