Reading Solar Panel Label

That means that the solar panel has to be no hotter than 25 c to produce its rated max power.
Reading solar panel label. A spec sheet also provides information about the assumptions used to create a panel s operating. Right below the electrical ratings indicate the major performance output characteristics of the panel. Stay tuned for more. The panel temperature is the temperature that the actual solar panel itself will get to when it is on your roof.
Sw manufacturer solarworld 255 watt poly q cells q peak g4 1 product line of polycrystalline module 295. Installers engineers and designers should consider efficiency ratings. This temperature is critical because all solar panels lose efficiency as they heat up. As cell technology improves so do efficiency ratings.
The solar panel description usually starts with the name of the manufacturer then the category of solar module and afterward the solar panel wattage. Here are a couple of examples. We discuss what they mean and common errors made with them. Now you can read the label of a solar panel and figure out what each of the specs are.
On the lower part of the label there are icons of all the certifications this specific panel has passed. On average solar panel efficiency ranges from 15 to 20 with some panels as high as 23. Stay tuned and we ll have an upcoming blog post on how these specs all come together. We ll go over an example of how to size a system with the details.
