CONCLUSION Photovoltaic power for irrigation costs are competitive with traditional energy sources for small, remote applications, if the total system design and utilization timing are carefully considered and organized to use solar energy as efficiently as possible. In the future, when the prices of fossil fuels rise and the economic advantages of mass production reduce the peak watt cost of the photovoltaic cell, photovoltaic power will become more cost competitive and more common.
