How does shading affect Solar Panel Electricity Output?The simple answer is a lot. The more detailed answer is that it depends on your inverter setup. If you had separate strings on the inverter or micro inverters then the impact of shading on panels can be mitigated and generation from the unshaded panels maintained.
For shading such as below with a telegraph pole casting a shadow over the panels in winter this would be a suitable option to optimise the output of the unshaded panels.
