Framed solar module with special glass and Sunpower cells of the highest quality class.
Equipped with rear contacts and delivered in a noble black anodized aluminum frame.
With a particularly low temperature coefficient and the special internal circuitry for a high open circuit voltage, this solar module allows more energy yield*) even at higher temperatures as well as in twilight.
The connection is made via prepared, 0.9m long cables with MC4 connectors.

*Improved temperature coefficient ensures 25% less power loss due to heating (compared to conventional panels). To explain: the manufacturer's performance specification always refers to 25 degrees cell temperature. However, a panel in the sun will easily reach 70°C, which results in significantly less power. In winter, on the other hand, a panel may well provide more power than originally specified by the manufacturer due to the low temperatures. These panels offer more power even at higher temperatures as well as in twilight. Responsible for this are the cells used, which are significantly more sensitive to a broader light spectrum. This means that charging is possible earlier in the morning and longer in the evening. With an efficiency of 24.2 %, this solar module permanently generates more energy than comparable models on the market.
