5 Signs Your Solar Plant Needs an Audit

A solar system that was performing well at installation can quietly lose efficiency over time. Here are five signs it might be time for a professional audit.

1. Your generation has dropped noticeably compared to the same period last year, even after accounting for seasonal variation.

2. You notice visible dust, bird droppings, or debris accumulation on panels that hasn't been cleaned in months.

3. Your inverter displays error codes or has been showing reduced efficiency readings.

4. Parts of your array appear to be in shade for longer periods due to new construction or tree growth nearby.

5. It's been more than 2-3 years since your last professional inspection.

A Solar Plant Audit from Greennub identifies the root cause of underperformance using thermal imaging, IV curve tracing, and detailed generation analysis — giving you a clear action plan to restore performance.
