Abstract
Ultimate focus of our study is to increase the efficiency of solar panel and its life time. The V-I characteristics, power calculations, variation of power with load, efficiency of solar panel are studied. The calculations are made at different timings, different heights and different days. From this study we can know the availability of sunlight during office hours, so that solar energy can be used for entire day without any hurdle. Solar panel efficiency can be known from calculation of Fill factor. Increased Fill factor increases efficiency of solar panel. By knowing maximum power, one can know the peak loads handled by solar panel .Solar panel peak power helps in preventing the photovoltaic panels from damaging, thus increasing the life time. From calculation of fill factor, we can also select the best solar cells from the available in market. From our study, we can also know watt peak, which is a measure of panels peak performance, it also tells amount of electricity solar panel produces. Watt peak information also tells about the best PV system out of many. V-I Characteristics at different temperatures and different loads helps us to optimize power characteristics, which can be known from Maximum power point of solar panel in full sunlight. If enough current is not taken from panel at a particular load, then power is not maximized, or if too much power is taken then voltage collapses and panel damages. The optimum current drawn is roughly proportional to amount of sunlight striking the panel. For best performance panel temperature must be low.
