Optimal Conversion of Solar Energy of Statically Mounted Systems in India
In this paper, the optimum energy conversion conditions of stationary panels are calculated at different latitudes for 180 days of a year to cover various angular orientation of sun’s rays on the earth. On a given day, the incident energy flux of the sun is resolved into three components, and the conversion efficiency is based on the flux normal to the panels. The efficiency of conversion is measured with respect to a solar tracking process. The number of days in a given year are divided into two groups – one between the winter solstice and the spring equinox, and another between the spring equinox and the summer solstice.
The results show that, there exist two maxima, one for each of the two periods. By setting the panels at each of these maxima significant (of the order of 5% over the single optimal setting condition also derived in this work) improvement in energy conversion can be achieved.
