Solar energy can help farmers save money, reduce pollution and increase their self reliance. Because farming can be very energy intensive, small-scale solar technologies can help farmers meet their energy needs and reduce their dependence on fossil fuels. Some of these technologies also help increase productivity and product quality. Solar technologies can be used to provide space and water heating or to generate electricity to provide power for a variety of applications. Depending on the price of electricity in the local area, solar electricity can be economical even fifty feet from a grid connection, depending on the application. Solar powered electric fence equipment can be moved from one remote location to another, eliminating the need for running and maintaining a diesel or gasoline powered generator. A solar electric system is reliable and versatile. Basic components include the panel, the battery and a charge controller to keep the battery from overcharging. These systems can be used with efficient light fixtures, ventilation fans, pond aerators and deicers, and small appliances or other equipment with small motors (see Solar Electric Applications table on page 3).
