The inspection generally include factors such as: Visual Inspection: Visual inspection of solar panels include checking for visible defects, such as cracks, discolouration, scratches, or dents on the solar module, as well as any abnormalities in the framing or glass, junction box, and wiring.
Why does a quality solar panel have a lower energy production rating?
A quality panel has a lower tolerance of energy production rating because it will produce closer to its advertised energy production. This is the amount of energy the solar pales drop when at a specific temperature. If the coefficient is high, the panel produces less energy at the rated temperature. A temperature coefficient below 0.5% is good.
How to choose a solar panel?
It is helpful to decide what type of panels you want before comparing brands and panel features. A standard solar panel may have a 12-14 percent efficiency rating, whereas a high-efficiency solar panel may approach 20% efficiency. Efficiency is essential. It tells you the percentage of sunlight that the panel will capture.
