Japanese electronics manufacturer Panasonic has launched an all-black residential heterojunction panel series that is compatible with its Evervolt lithium-ion storage solution for residential solar installations.
The new module series, which will be available from the second quarter of this year, features a power output ranging from 420 to 430W and an efficiency of 21.7% to 22.2%.
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 reportedly able to operate at 92% of their original performance at the end of the guarantee period.
Furthermore, the Japanese module maker launched a smaller version of the same module in a series with a power output of between 390 and 400 W and efficiency ranging from 20% to 20.5%.
“Both new models are covered under Panasonic’s EverVolt AllGuard All System Warranty when purchased with EverVolt ESS 2.0, which covers solar panels and battery storage when bundled together,” the manufacturer said in a statement. “The EverVolt AllGuard All System Warranty covers product performance and labor across all major system components, including 25 years of coverage for Panasonic solar panels; 25 years for the racking system; 10 years for the inverter and 10 years for Panasonic EverVolt 2.0 ESS.”
Panasonic 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.

Do these stated backup capabilities make sense? Shouldn’t they depend on load? If nothing is on in your home, even the mini should last a lot longer than 3 hours. Am I missing something here?
