The Panasonic EverVolt Solar Module Black Series redefines efficiency standards through the use of advanced heterojunction cell technology (HJT), which minimizes energy losses at the silicon layer boundaries. These panels are a direct response to the problem of efficiency drops on hot days - they feature one of the market's lowest temperature coefficients, guaranteeing stable power production even in extreme sunlight. The unique design of the frame and deep black cells makes the installation nearly invisible on the roof, which will be appreciated by investors who value premium aesthetics without compromising on power. Unlike standard solutions, this series is characterized by exceptionally low degradation, offering users a power guarantee of at least 92% after 25 years. This is an ideal choice for homeowners with limited roof space, where every square meter must generate maximum yields. By choosing these modules, the investor gains confidence backed by comprehensive protection covering not only the hardware, but also performance and labor, which clearly distinguishes the offer from mass competition. An innovative water drainage system further prevents dirt accumulation, resulting in longevity and maintenance-free operation of the system for many decades.

Watch-outs
25 year performance warranty

Bottom 8% of the HJT 400-450 W segment, against a median of 30 yrs. Ranked 9,798th in the whole database.

-0.260 %/°C temperature coefficient

Bottom 23% of the HJT 400-450 W segment, against a median of -0.240.

What owners get
Highest efficiency in the segment

Efficiency of 21.6-22.2% exceeds all comparable 410 Wp peer modules (VDS Renewable 20.4%, Sunket 21%, Luxor Solar TOPCon 21.33%), delivering higher energy yield from the same roof area.

Industry-leading temperature coefficient

The HJT cells achieve a temperature coefficient of -0.24%/°C, one of the best results on the market, limiting power losses during heat and ensuring more stable output in hot climates.

Comprehensive 25-year warranty

The warranty covers product, power performance (min. 92% after 25 years), and labor simultaneously - Panasonic confirmed in April 2025 that despite exiting production, all existing warranties remain valid.

Premium 'Full Black' aesthetics

The deep black frame and cells create a uniform, nearly invisible look on the roof, a key advantage for residential installations where facade aesthetics matter to the investor.

Low long-term degradation

The guaranteed minimum of 92% of rated power after 25 years is clearly better than the typical 84-87% offered by standard PERC modules with a 25-year linear warranty.

Trade-offs
Production discontinued (April 2025)

On April 28, 2025, Panasonic announced its complete exit from the solar panel and energy storage business. The EverVolt Black series is no longer available for purchase, limiting future access to service, module replacements, and system components - despite commitments to honor existing warranties.

No bifacial variant

Unlike the competing Luxor Solar Eco Line TOPCon (410-430 Wp, Glass-Glass, bifacial option), the EverVolt Black series is monofacial only, excluding the additional albedo-driven yield available with light-colored surfaces or ground-mounted installations.

Common questions

6 answered
What is the power output warranty on Panasonic EverVolt Solar Module Black Series panels?
The EverVolt Black Series includes a 25-year power warranty guaranteeing at least 92% of nominal power output after 25 years — one of the strongest retention rates in the industry, compared to the 80–83% typically offered by standard modules. A separate 25-year product warranty covers manufacturing defects and material failures.
How do Panasonic EverVolt Black Series panels perform during hot summer days?
Thanks to HJT cell technology, EverVolt Black Series modules carry a temperature coefficient of -0.26%/°C, among the lowest in their class. This means significantly less power loss on hot days versus standard PERC panels. At a cell temperature of 65°C, these modules retain several percentage points more output — a measurable advantage in high-irradiance locations.
Is the Panasonic EverVolt Solar Module Black Series still available for purchase?
No. Panasonic officially announced the discontinuation of its entire EverVolt product line — solar modules and battery storage — in 2025. The EverVolt Black Series is no longer in production. All existing installations remain fully covered: Panasonic has confirmed it will honor all warranty obligations for installed and in-progress systems.
What are the real-world advantages of HJT technology in EverVolt Black Series over mainstream PERC cells?
HJT cells combine crystalline silicon with thin-film amorphous silicon layers, minimizing carrier recombination at cell boundaries. In practice: efficiency above 21%, lower temperature-related losses, and lower annual degradation than PERC. Over a 25-year system lifetime, HJT generates more kilowatt-hours per square meter, directly improving LCOE.
Are Panasonic EverVolt Black Series panels a good fit for a small roof with limited area?
Yes — with 410 Wp max power and efficiency above 21%, EverVolt Black Series modules are specifically well-suited to buildings with limited roof space. Fewer panels are needed to reach a target system output, reducing mechanical load on the roof structure and lowering BoS installation costs.
Does the all-black design of EverVolt Black Series affect panel performance?
The EverVolt Black Series features a uniform black frame, black backsheet, and deep-black HJT cells for a near-invisible rooftop appearance. The all-black aesthetic does not compromise performance — the 410 Wp HJT cells deliver full rated output, and the module's water drainage design prevents dirt buildup, keeping both efficiency and appearance stable over decades.
