solar panel preston

Solar Photovoltaic (Solar PV) systems are significantly impacted by shading as it can reduce the output of the PV array. Ideally the Solar PV systems should be located in a shade-free area. However most grid-connected systems are often located on-roofs in built locations, where shading is largely inevitable. There are many forms of temporary shading that can affect the performance of the solar panel preston including: snow, fallen leaves and general dirt. Nonetheless generally this loss of efficiency amounts to between 2 per cent and 5 per cent and can be overcome by paying careful attention to the arrangement and angle of the solar panel preston. A tilt of 12 degrees or more allows for the solar panel to self-clean, as greater tilts increase the flow of rain and thus helps to get rid of any potential shading blockages. By arranging the Solar PV modules horizontally this enables losses made by the shading to be reduced by half (in comparison to if it was positioned vertically).
