COMPUTATIONS OF DAILY SOLAR RADIATION ON INCLINED SURFACES

摘要

The quantity of solar radiation impinging on the surface of materials is of extreme importance to scientists concerned with outdoor weathering of materials. Forecasting this solar radiation load and its effects is difficult because of the many factors (astronomical, atmospheric, and material surface conditions) that may alter the quality and quantity, and hence the effects of the incoming radiation. This report deals with the theoretical computation of the angle at which samples of materials should be exposed if they are to receive maximum solar radiation, taking into consideration only the uniqueness of the astronomical and surface position factors. Data summaries are presented that show the amount of radiation impinging on the surface of materials inclined at different angles for worldwide locations.
