Finding an unshaded spot is best, but sometimes shading is unavoidable. Some solar panel systems can minimise the impact of shading using ''optimisers''. Solar optimisers help improve the overall performance of your solar panel system. So, if one panel is shaded, it doesn''t impact how much electricity the other panels can generate.
