This is a leading result for half-cut PERC technology. - **Comprehensive 25-year AllGuard/TripleGuard warranty** - The warranty simultaneously covers product, power, parts, and labor for 25 years, with guaranteed power retention of at least 86% after that period. Panasonic committed to honor these terms despite exiting the PV market in April 2025. - **Low degradation via 100% PID-Free design** - The combination of half-cut PERC cells with full resistance to Potential Induced Degradation (PID) delivers one of the lower annual power-loss rates in the segment, resulting in more predictable energy yield over the module's lifetime. - **Better performance under partial shading** - The half-cut cell architecture limits production drops caused by shade from chimneys, trees, or roof elements during the day, which matters for typical single-family rooftop installations with irregular sun exposure. - **Reputation and experience of a tier-1 manufacturer** - Panasonic is a Japanese corporation operating since 1918, with a long history in photovoltaics and a recognized brand in premium markets (e.g., the US), historically translating into high build quality and tight process control. ## Cons - **Production discontinued - limited availability** - Panasonic exited the solar PV market on April 28, 2025, ending the entire EVERVOLT line, including the PK Black Series. Despite commitments to honor AllGuard/TripleGuard warranties, availability of service, spare parts, and replacement modules for claims will be limited. - **No bifacial technology** - The series uses only monofacial PERC cells, while the comparable competitor Solitek SOLID Bifacial (370 Wp, 19.57% efficiency) offers additional energy yield from the rear side of the module - a potential advantage lost when installing on bright ground surfaces or elevated racking. ## About this series The Panasonic EVERVOLT Solar Module PK Black Series consists of all-black panels designed for aesthetically pleasing rooftop installations and stable energy production in real-world conditions. The use of **half-cut cells with PERC technology** improves light utilization and reduces losses, which translates to high efficiency, especially in situations where every fraction of a roof area counts. A key feature is **improved performance under partial shading** - the series helps minimize energy losses when shadows from chimneys, trees, or roof elements appear during the day. In practice, this is a solution for single-family homes and small prosumer installations that need to operate reliably even in the summer, when the modules heat up significantly, thanks to **excellent temperature characteristics**. Another important argument for investors is the **long-term warranty**, which covers not only parameters but also durability, making it easier to compare with competitors that focus solely on nominal power. ## Notable figures - At 19.2% efficiency, this panel is on par with typical \*\*PERC 0-400W\*\* modules - At 191.8 W/m² power density, roof space requirements are typical for \*\*PERC 0-400W\*\* panels - Temperature coefficient of -0.34%/°C matches the \*\*PERC 0-400W\*\* median - At 19.5 kg, weight matches the \*\*PERC 0-400W\*\* median - In the top 92% for efficiency among all PERC panels ## Questions ### Is the Panasonic EVERVOLT Solar Module PK Black Series still available for purchase? No. Panasonic exited the solar panel market in 2023 and discontinued the entire EVERVOLT lineup, including the PK Black Series, ceasing sales across North America. The modules are no longer available as new stock from authorized distributors. Panasonic has stated it will continue to honor all warranties for previously installed systems. If you are looking for a comparable all-black PERC module, consider current offerings from other manufacturers. ### What warranty does the Panasonic EVERVOLT PK Black Series carry and what does it cover? The EVERVOLT PK Black Series comes with a 25-year product warranty covering defects in materials and workmanship, and a 25-year linear power warranty. Panasonic guarantees that after 25 years of operation the module will retain at least 86% of its rated output of 370 W. The long-term power warranty protects the investor against excessive cell degradation and simplifies the calculation of return on investment over the system's lifetime. ### How does the half-cut PERC cell technology affect the performance of the Panasonic EVERVOLT PK Black 370W? The EVERVOLT PK Black Series 370 W panel uses 120 monocrystalline half-cut cells with PERC technology. Splitting each cell in half reduces internal resistance and resistive losses, while the additional PERC reflective layer behind the cell boosts light absorption. The result is a module efficiency of 20.3%, which is competitive for the all-black 120-cell class of products from the 2022-2023 generation. ### Does the Panasonic EVERVOLT PK Black Series handle partial shading well, for example from a chimney or trees? Yes, the half-cut cell layout significantly reduces power losses under partial shading conditions. When one row of cells is shaded, the impact on the rest of the module is lower than in panels with full-size cells, because each half-cell operates in a separate subcircuit. The PK Black Series is therefore a solid choice for rooftops with chimneys, dormers, or nearby vegetation. For maximum optimization under heavy shading, pairing the panels with power optimizers or microinverters is recommended. ### How does the Panasonic EVERVOLT PK Black 370W perform at high temperatures during summer? Like all monocrystalline silicon panels, the EVERVOLT PK Black Series loses some output as cell temperature rises. The manufacturer specifies an operating range of -40°C to +85°C. The PERC technology combined with the half-cut cell architecture results in slightly lower temperature coefficients compared to older full-cell BSF modules, translating into better real-world energy yield on hot summer days common in Central European climates. ### What type of installations is the Panasonic EVERVOLT PK Black Series best suited for, and how many panels are needed for a typical system? The PK Black Series targets residential prosumer installations on sloped rooftops where aesthetics (all-black appearance) and predictable performance are priorities. A typical 10 kWp residential system would require approximately 27 modules at 370 W each. The panel dimensions and weight are compatible with standard racking and mounting systems widely available on the European market, simplifying integration with most balance-of-system components. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/evpv350pk-b03605c64373.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Cooler, lighter, +4.1 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +4.1 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +3.9 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.9 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -50 W, +3.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +3.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +3.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.8 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 | +30 W, +3.8 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 | +50 W, +3.8 pp, +5 yr warranty | | [Panasonic EVPV360PK](https://comparepv.com/panel/panasonic-evpv360pk) | 360 W | +10 W, +0.5 pp | | [Panasonic EVPV370PK](https://comparepv.com/panel/panasonic-evpv370pk) | 370 W | +20 W, +1.1 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +160 W, cooler, +5.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +145 W, cooler, +5.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +155 W, cooler, +5.5 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +155 W, cooler, +5.5 pp | --- Source: https://comparepv.com/panel/panasonic-evpv350pk Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
