| Abstract | Solar energy varies by season, by atmospheric layer, and even by hour. Solar heat collectors transform solar energy into electricity by absorption of the photons into a semiconducting crystal lattice. Several types of solar heat collectors and photovoltaic cells are presented and discussed in the report. The use of photovoltaic cells to provide energy for water pumps was begun in 1978. The output of the pump varies with the amount of sunlight reaching the cells; therefore, a battery for storing the energy is a necessary part of the photovoltaic pump system. The characteristics, specifications and technical performance of several types of photovoltaic pumps are discussed in detail. A detailed economic analysis is presented, comparing cost effectiveness with diesel and hand pumps. A case study of three photovoltaic pumps in Ethiopia is presented in Appendix A. |
