Overview
Economic
Viability Of Photovoltaic Water Pumping Systems
Abstract
A
comparison of the economic viability of photovoltaic and diesel water pumping
systems is presented for system sizes in the range 2.8 kWp to 15 kWp. Actual
performance data from installed systems are employed for the base case.
Sensitivity analysis is carried out to generalize results for other locations
and conditions. The effect of system oversizing due to the mismatch of water supply
and demand patterns on the economic viability of PV water pumping system is
illustrated based on real
data and three-year operational experience of eight installations. Investment
prospects in PV water pumping applications for different selling price
scenarios of water have been investigated.
