How shading impacts your solar system performance in New South Wales
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.
New South Wales has a temperate climate with 5.2 peak sun hours per day.
