Investigations aiming to assess the potential of photovoltaic systems relevant for the energy economy were carried through in Switzerland and were focused on the following points: description of the technical systems; development of a computer program to establish potential energy yields from photovoltaic systems for different seasons and locations in Switzerland; assessment of the surfaces possibly available for installation of photovoltaic systems; discussion of technical and energy economy aspects relating to the integration of solar energy systems into the existing public grid. Individual subjects dealt with are consumer categories for photovoltaic systems, the solar irradiation data of Switzerland, and solar cell technology (mode of function, electrical components, space requirements of solar cells, solar energy distribution, cost and losses of electric lines). Subsequent descriptions of photovoltaic systems indicate cost structure, environmental conditions, an Alpine photovoltaic power plant and photovoltaic systems to be installed on the roofs of buildings. The computer program is presented, estimates of the surface of available sites are given and influences on the Swiss energy economy are indicated; the economic efficiency of solar cell systems is finally discussed.
