Pumping Water for Irrigation Using Solar Energy Page 8 Figure 8b. Net present cost comparison for power sources for irrigation for land area of 5 ha (12.4 ac) as price of photovoltaic system is decreased and price of fuels is increased. The $1.00/Wp photovoltaic system was competitive with a diesel system at a 270 percent increase of the 1989 price of diesel to $4.63/gallon. CLOSING REMARKS The use of photovoltaic power for irrigation is a well- matched application of solar energy supply to energy need, because both the plant water needed and the availability of water supplied by a photovoltaic system depend upon the solar irradiance available. Complete utilization of all of the solar power available, however, without an energy (battery) or fluid power (elevated water storage tank) storage unit is impossible for two reasons: 1) Solar energy will be available on days when no additional water is required by the plants, i.e., a sunny day after a rainstorm. 2) Since the ratio of ETp to fluid power is greater in the summer months than the winter months in Florida, the photovoltaic system must be oversized for the winter months to guarantee an adequate water supply for the crop during the summer months. The vegetable winter growing season of Florida (September - May) was used for the irrigated area example in this paper. The efficient application of photovoltaic power to an irrigation system requires that the solar power availability pattern at the application site match the annual crop water need closely and that the crop growing season be lengthy to utilize the photovoltaic system as much as possible throughout the year. Since the increase in price per increase in unit power output of a photovoltaic system is greater than that for a diesel, gasoline, or electric system, photovoltaic power is more cost competitive when the irrigation system with which it operates has a low total dynamic head. For this reason, photovoltaic power is more cost competitive when used to power a micro- irrigation system as compared to an overhead- sprinkler system. In conclusion, photovoltaic power for irrigation is cost competitive with traditional energy sources for small, remote applications, if the total system design and utilization timing is carefully considered and organized to use the 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,PDF Image | Pumping Water for Irrigation Using Solar Energy
