Reading solar panel label.

Now you can read the label of a solar panel and figure out what each of the specs are. Here are a couple of examples. This temperature is critical because all solar panels lose efficiency as they heat up. On the lower part of the label there are icons of all the certifications this specific panel has passed.

The panel temperature is the temperature that the actual solar panel itself will get to when it is on your roof. We ll go over an example of how to size a system with the details. Stay tuned and we ll have an upcoming blog post on how these specs all come together. Approximate voltages to determine nominal voltage of solar panels.

That means that the solar panel has to be no hotter than 25 c to produce its rated max power. We discuss what they mean and common errors made with them. The solar panel description usually starts with the name of the manufacturer then the category of solar module and afterward the solar panel wattage. Installers engineers and designers should consider efficiency ratings.

Right below the electrical ratings indicate the major performance output characteristics of the panel. A spec sheet also provides information about the assumptions used to create a panel s operating. As cell technology improves so do efficiency ratings. The example photo of a solar pv label indicates name and address of the manufacturer and the solar module type blackened.
