Solar thermal energy is one of renewable energy sources which are expected to contribute to reduction of CO_2 emission. Promotion of using solar thermal energy is effective for reduction of CO_2 emission in residence and business. In this paper, a simple flat plate solar collector is made for evaluation its performance of solar energy collection. In the field measurement of location the collector on open space, heat losses are evaluated with measuring temperature at each component of the collector. From the experiment, it is revealed that heat losses by convection at air layer and radiation from collector plate and the reduction of heat losses is essential for improvement of the heat collection efficiency. In the condition of pressure reduction of air layer, it is confirmed that its performance is comparatively improved.
