Called EverVolt Solar Modules, the new panels will initially be available in two product series in the U.S. market, starting from February. A standard series includes two modules with power outputs of 360 W and 370 W and efficiency ranging from 20.6% to 21.2%, while a second, black series comprises two products with outputs of 350 W and 360 W, and efficiency of 20-20.6%.
All the four modules have a temperature coefficient of -0.26%, which Panasonic claims is one of the industry's lowest. “With one of the industry's lowest annual degradation rates, power output of at least 92% is guaranteed after 25 years,” the manufacturer stated.
The modules are based on n-type half-cut cells with heterojunction technology, which are said to result in minimal low-induced degradation (LID) and potential-induced degradation (PID).
Panasonic had launched its EverVolt storage system in September 2019. The battery has a storage capacity ranging from 5.7 kWh up to 34.2 kWh. The 5.7 kWh ‘mini’ version of the storage system has an average back-up capability of three hours, the 11.4 kWh standard option six hours and the 17.1 kWh ‘plus' product nine hours.
This copy was amended on 04/01/20 to reflect the standard products have power ratings of 360 W and 370 W, rather than both being rated 370-380 W, as previously stated. The black products have ratings of 350 W and 360 W, rather than both having 360-370 W output, as previously reported.
