Abstract :
This is a symposium of four talks by outstanding leaders in the field. Because this is the first program of this subject at our general meeting, it is designed to introduce the subject to the community of EE´s. The opening talk, in presenting an over-view, displays the scope and emphases of the ERDA program, factors that are little known outside the active participants in the field. The application to heating and cooling of buildings is the nearest one to widespread use and impacts a huge demand area. Silicon solar Cells are chosen as a fairly well-known representative of the solar electric technologies and in which significant advances are being mode. The final talk cover a number of interesting systems question that are both importatnt to field of solar electricity and likely to concern EE´s.
