How shading impacts your solar system performance in East of England
Even small amounts of shading can disproportionately reduce solar output. A shadow covering just one cell in a string can reduce the output of the entire string. New tree growth, nearby construction, or seasonal changes in sun angle can all introduce shading that didn't exist when your system was installed.
East of England has a maritime climate with 4.1 peak sun hoursper day. The UK's cooler temperatures benefit panel efficiency but shorter daylight hours affect annual output.
