A~ract--In order to design and realize a solar chimney of greatest efficiency for drying agricultral products, we have investigated the natural convective flow between two heated vertical plates. The equations of continuity, momentum and energy are solved by a finite difference method, taking into a

β¦ Synopsis
A~tract--The effect of solar radiation and temperature on the performance of solar panels was tested in order to improve the power output of the panels. A system comprising of two stages was used : a water circulation system was found to be necessary to overcome the degradation in Vo~ with panel temperature and at the same time, an alcoholic solution of a number of fluorescent substances were tested to enhance the output power of a monocrystalline silicon solar panel, by modification of the solar radiation spectrum towards a region where the silicon response is more favourable.
