This results in less power loss during summer heat compared to typical PERC panels (usually 0.35-0.40%/°C). - **Comprehensive 25-year AllGuard warranty** - The warranty simultaneously covers product, power performance, and labor (AllGuard/TripleGuard program) for 25 years, with a guaranteed minimum power output of 92% after that period - a broader scope of coverage than the standard linear warranty offered by many tier-1 manufacturers. - **Partial shading resilience** - The half-cut cell layout combined with HJT technology limits the impact of partial shading (chimneys, dormers, trees) on the whole string's output, improving production stability under real rooftop conditions. - **Full Black aesthetic design** - The all-black frame, backsheet, and cell styling gives a uniform look on modern roofs, an important selection criterion for residential customers who prioritize installation aesthetics. ## Cons - **Production discontinued, no successor series** - Panasonic officially exited the solar and energy storage market in April 2025, ending the EverVolt line. Existing AllGuard warranties are still being honored, but the series is no longer available for purchase, and long-term service and spare-parts availability now depends on the post-exit support structure. - **Manufacturing outsourced to REC Group since 2022** - Panasonic stopped manufacturing its own cells and modules back in 2022, outsourcing production to REC Group, while its share of US solar installations fell from 35% in 2020 to just 6% by 2024. The premium brand was no longer fully backed by in-house manufacturing capacity during the series' final years on the market. ## About this series The Panasonic EVERVOLT Solar Module Black Series 360K/350K is designed to maximize energy generation from a limited roof area - making it ideal for situations where every square meter and the aesthetics of the installation are important. The modules are distinguished by their **full black design**, which ensures a consistent look on modern roofs, without any distracting frame or cell contrasts. A key advantage is the **HJT half-cut heterojunction technology**, which improves light conversion and operational stability in real-world conditions. In practice, this means **improved performance at high temperatures** and more predictable output when the sun heats the modules more intensely. Furthermore, the design supports **continuous operation even with partial shading**, which is important for chimneys, skylights, or nearby trees. This is the ideal choice for homeowners and small businesses who want high-quality premium modules and reliable operation - thanks also to the **long, comprehensive warranty** that covers not only the product but also its operating parameters. ## Notable figures - Efficiency of 20.6% matches the \*\*HJT 0-400W\*\* median - At 205.9 W/m² power density, roof space requirements are typical for \*\*HJT 0-400W\*\* panels - At -0.26%/°C, hot weather performance is typical for \*\*HJT 0-400W\*\* panels - 19.5 kg weight - 2.0 kg lighter than \*\*HJT 0-400W\*\* median (21.5 kg), reducing installation effort - Ranked #11093 out of 14005 panels for efficiency in the database ## Questions ### Is the Panasonic EVERVOLT Black Series 360K/350K still available for purchase? The EVERVOLT Black Series 360K/350K has been discontinued by Panasonic and is no longer in active production. Availability depends entirely on remaining distributor stock. If you need a similar all-black aesthetic with HJT technology, Panasonic's newer EVERVOLT PK Black Series 370/360W is the direct successor and is worth considering. ### What warranty does the Panasonic EVERVOLT Black Series 360K/350K come with? Panasonic provides a 25-year product warranty and a 25-year power output warranty. After 25 years of operation, at least 92% of the rated power output is guaranteed. This is among the most comprehensive warranties in the premium module segment and supports predictable energy yield calculations over the full system lifetime. ### How does HJT half-cut cell technology in the EVERVOLT Black 360K work in real-world conditions? HJT (heterojunction) technology stacks thin amorphous silicon layers onto crystalline cells, achieving a temperature coefficient of approximately -0.26%/°C. In practice, this means output losses on hot summer days are significantly lower than with standard PERC modules. The half-cut cell layout reduces resistive losses and improves performance under partial shading from chimneys, dormers, or nearby trees. ### What are the dimensions and weight of the EVERVOLT 360K panel, and is it manageable for a rooftop install? The EVERVOLT 360K measures 1721×1016×30 mm and weighs 19.5 kg. For a premium 360 W module, these are compact and manageable specs. A two-person rooftop installation on a pitched roof is physically feasible, but for warranty compliance and electrical safety, the work should always be performed by a certified PV installer. ### Does the all-black design of the Black 360K/350K series affect module efficiency? A black backsheet and black frame do marginally raise operating temperature compared to standard white-backsheet modules. In the EVERVOLT Black series, this effect is largely offset by the excellent HJT temperature coefficient of -0.26%/°C. The aesthetic benefit of a uniform rooftop appearance therefore comes at a minimal efficiency cost, making it a rational choice for design-conscious homeowners. ### Are the Panasonic EVERVOLT Black 360K/350K modules a good fit for a small roof with limited space? Yes, maximizing output from a limited roof area is a core use case for this series. The 360K module achieves approximately 20.6% efficiency, placing it at the top of its format class. Compared to standard PERC modules at 19–20% efficiency, this can translate to one or more additional watts per square meter across the array, which matters significantly on constrained roof sections. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/evervolt-black-series-datasheet-030000d91f93.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | -30 W, lighter, +2.5 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | -30 W, lighter, +2.5 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -40 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +40 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +40 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +2.4 pp, +5 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | +40 W, +2.0 pp, +15 yr warranty | | [Panasonic EVPV350K](https://comparepv.com/panel/panasonic-evpv350k) | 350 W | -10 W, -0.6 pp | | [Panasonic EVPV370](https://comparepv.com/panel/panasonic-evpv370) | 370 W | +10 W, +0.6 pp | | [Panasonic EVPV380](https://comparepv.com/panel/panasonic-evpv380) | 380 W | +20 W, +1.1 pp | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +80 W, +2.3 pp, +5 yr warranty | | [Mysolar USA MS440N-DHBA](https://comparepv.com/panel/mysolar-usa-ms440n-dhba) | 440 W | +80 W, +2.1 pp, +5 yr warranty | | [Jetion JT435SYk(B)](https://comparepv.com/panel/jetion-jt435syk-b) | 435 W | +75 W, +2.1 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/panasonic-evpv360k Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
