In recent years there has been considerable interest in developing flat-plate solar collectors for home heating needs. The typical collector configuration consists of an absorbing surface that is thermally insulated on the edges and on the back side. Solar radiation is transmitted through one or more glass cover plates before reaching the absorber. The collected energy is removed by circulating water through tubes that are in good thermal contact with the absorber. Identify all the energy exchange processes that influence the performance of the collector. Suggest design features that would increase collection efficiency.
