Solar Water Pumping Project for commercial purposes

Kitui Mulutu Solar Water Pumping Project for commercial purposes
Pumping begins at 7:30am in the morning and ends at 6pm evening thanks to Trina bifacial solar panels. Trina144 half-cut cells 545W, bifacials PV modules generate power on both sides, with high efficiency is coupled to AC/DC pump (2.2kw/3HP, 255metres discharge 5,200L/h, outlet 1")
Mr. Musyimi (client) spent a staggering shs,700,000 for setting up solar system for pumping and a whopping shs.1 million for borehole drilling, totaling to shs.1.7million!
Projection:
The system fills 5pieces of 10,000L tanks in 9-10hrs under low light intensity of the Sun (assuming worst case scenario).
Selling 20L of water at shs.5
50,000L will generate shs.12,500 in a day (other factors kept constant).
In any single month, water consumption will generate shs375,000 or shs4.5million a year.
Return on Investment is well under 5months. Quite intriguing.
Location: Kitui County.
Lead Time: 2 days(for solarization)
Lead Time: 7 days( for drilling).
Project Costs: kes 700,000.(Solarization only)
System Life 12-13years.
Profit projections for 12years kes 600 million!
