Enphase — partial shading
Shading affects Enphase systems the same way it affects any solar equipment. New tree growth, nearby construction, or seasonal changes in sun angle can introduce shading that reduces output significantly.
Partial shading details
New tree growth, nearby construction, or seasonal shading patterns reducing output on part of the array.
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.
