One point to note about Solar PV arrays is that when a string inverter is used, each panel will only perform to its weakest component. Therefore, if one panel is shaded (for example, by a chimney), then every panel in that array will act like it is shaded. This is a very important point to note when designing your system. To overcome this issue, you can have a split string inverter (two separate strings) or use micro inverters which mean that each and every panel will perform independently of each other – planning and foresight can significantly improve your system!
