Reading Solar Panel Label

On the lower part of the label there are icons of all the certifications this specific panel has passed.

Reading solar panel label.

This temperature is critical because all solar panels lose efficiency as they heat up. The example photo of a solar pv label indicates name and address of the manufacturer and the solar module type blackened. The panel temperature is the temperature that the actual solar panel itself will get to when it is on your roof. Now you can read the label of a solar panel and figure out what each of the specs are.

Approximate voltages to determine nominal voltage of solar panels. As cell technology improves so do efficiency ratings. Installers engineers and designers should consider efficiency ratings. Stay tuned and we ll have an upcoming blog post on how these specs all come together.

On average solar panel efficiency ranges from 15 to 20 with some panels as high as 23. Stay tuned for more. We ll go over an example of how to size a system with the details. Sw manufacturer solarworld 255 watt poly q cells q peak g4 1 product line of polycrystalline module 295.

Here are a couple of examples. A common mistake that inexperienced solar power engineers make is not understanding the solar module labeled values. The solar panel description usually starts with the name of the manufacturer then the category of solar module and afterward the solar panel wattage. We discuss what they mean and common errors made with them.
