Reading solar panel label.

A common mistake that inexperienced solar power engineers make is not understanding the solar module labeled values. This temperature is critical because all solar panels lose efficiency as they heat up. The panel temperature is the temperature that the actual solar panel itself will get to when it is on your roof. 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. As cell technology improves so do efficiency ratings. Here are a couple of examples. Installers engineers and designers should consider efficiency ratings.

A spec sheet also provides information about the assumptions used to create a panel s operating. On the lower part of the label there are icons of all the certifications this specific panel has passed. We ll go over an example of how to size a system with the details. Right below the electrical ratings indicate the major performance output characteristics of the panel.

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. Now you can read the label of a solar panel and figure out what each of the specs are. Sw manufacturer solarworld 255 watt poly q cells q peak g4 1 product line of polycrystalline module 295.
