Protecting Your Investment. Maximizing Performance.

@) PURPOSE 
Photovoltaic (PV) systems are a significant investment that can 
provide decades of renewable energy when properly maintained. 
In Hawaii, intense UV radiation, salt air, humidity, wind, and rain 
can impact system performance and longevity. 
This guide helps you perform a safe visual inspection, identify 
developing issues early, and know when professional evaluation 
or maintenance may be needed. 
IMPORTANT: 
This guide is for visual inspections only. 
Do not remove panels, disconnect electrical 
components, or open electrical equipment unless 
you are trained and qualified to do so.

If storm damage is suspected, assume 
damaged electrical components may 
be energized. 
STEWARDSHIP PRINClf)LE 
Electricity and roof work both 
present hazards. A safe visual 
inspection is far more valuable 
than taking unnecessary risks. 
During this inspection you are evaluating the visible condition of 
the photovoltaic system and the surrounding roof area.
