The new module series, which will be available from the third quarter of this year, features a power output ranging from 370 to 380 W and an efficiency of 21.2% to 21.7%.

The panel's temperature coefficient is -0.26% per degree Celsius and the manufacturer offers a 25-year product guarantee and a 25-year power output guarantee. The panels are said to be able to operate at 92% of their original performance at the end of the guarantee period.

Furthermore, the Japanese module maker launched a black version of the same module in a series with a power output of between 360 and 370 W and efficiency ranging from 20.6% to 21.2%. “The new modules are the latest technological evolutions in our roadmap of innovative solutions designed with homeowners' and installers' needs in mind,” the company said in a statement.

Moreover, Panasonic said the cabinet of its Evervolt battery has been improved to stack more batteries and store more energy in a smaller space. “The improved cabinet will be 29x47x18 inches, 22 square inches smaller than the previous EverVolt battery storage model,” it explained. “In addition to offering both the AC- and DC-coupled options, the battery storage system can be scaled down to as little as 11kWh of energy storage or expanded to 102kWh.”

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.
