Tennessee (TN)
How shading impacts your solar system performance in Tennessee
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.

Self-check tip:
Check panels at different times of day. New tree growth or structures may cast shadows that didn't exist when the system was installed.
