This translates into higher energy yield from the same roof area. - **Industry-leading temperature coefficient** - HJT technology delivers a temperature coefficient of 0.26%/°C, notably below the typical 0.34-0.40%/°C for PERC or TOPCon modules. This means lower power losses on hot days, which matters during Polish summers. - **Triple Guard warranty with labor coverage** - The 25-year warranty covers product, power (92% guaranteed power output after 25 years), and installer labor costs during servicing simultaneously - a broader package than the standard linear warranty offered by most tier-1 manufacturers. - **LID-resistant N-type cells** - The use of N-type cells virtually eliminates light-induced degradation (LID), typical of older P-type technology, resulting in more stable energy production during the first years of operation. - **Reputable tier-1 manufacturer** - Panasonic is a Japanese conglomerate operating since 1918, with a long history in photovoltaics and a premium brand reputation that historically translated into high build quality and manufacturing control. ## Cons - **Production discontinued in 2025** - Panasonic announced on April 28, 2025 the complete withdrawal from the solar and energy storage market (market share fell from 35% in 2020 to 6% in 2024), ending the EverVolt line. Availability of service, spare parts, and identical replacement modules under warranty is limited - warranty claims may be fulfilled with a third-party equivalent panel or cash-value settlement instead of an original EverVolt unit. - **No bifacial variant** - The series does not offer bifacial technology, whereas the comparable Luxor Solar Eco Line N-type TOPCon at the same 410 Wp power rating is available in a Glass-Glass bifacial variant, which can increase energy yield with suitable mounting (e.g., on a reflective surface or in ground-mounted arrays). ## About this series Panasonic EverVolt is a module series based on **heterojunction (HJT)** technology, which effectively combines the advantages of crystalline and amorphous silicon. This advanced solution minimizes energy losses and ensures the highest efficiency even on the hottest days thanks to record-low temperature coefficients. Unlike standard solutions, EverVolt uses **N-type cells**, which practically eliminates the light-induced degradation (LID) effect and guarantees stable electricity production for decades. It is an ideal choice for homeowners with limited roof space who want to obtain maximum power from every available square meter of mounting surface. These modules effectively solve the problem of efficiency drops in the Polish climate, where summer heat often reduces real yields from traditional installations. What sets this series apart from the competition is the **comprehensive Triple Guard warranty protection**, covering the product, power, and installer labor costs during potential servicing. High aesthetic quality ensures the panels blend perfectly with modern architecture, while offering **minimal annual degradation** at a level significantly lower than market standards. This is a solid foundation for investments requiring top-class reliability and maintenance-free operation for many years. ## Notable figures - Efficiency of 22.2% matches the \*\*HJT 400-450W\*\* median - Power density of 221.6 W/m² matches the \*\*HJT 400-450W\*\* median - -0.26%/°C temperature coefficient - 0.02pp worse than \*\*HJT 400-450W\*\* median (-0.24%/°C), expect higher hot weather losses - Weight of 20.5 kg (2.5 kg below \*\*HJT 400-450W\*\* median of 23.0 kg) allows easier transport and roof mounting - #5817 for efficiency, #511 for temperature performance out of 14005 panels ## Questions ### What warranty does the Panasonic EverVolt series offer, and what does the Triple Guard package include? Panasonic EverVolt comes with a 25-year product warranty and a 25-year power warranty guaranteeing at least 92% of nominal power output after 25 years of operation. The unique Triple Guard package also covers installer labor costs during any warranty service — an uncommon benefit among module manufacturers. These warranties remain valid even for units purchased before the series was officially discontinued. ### What is HJT technology used in the Panasonic EverVolt, and why does it matter? HJT (heterojunction technology) combines N-type crystalline silicon cells with a thin amorphous silicon layer. This gives EverVolt modules an industry-leading temperature coefficient of just -0.24%/°C, minimizing output losses on hot summer days. N-type cells virtually eliminate LID (Light Induced Degradation), so the panel delivers stable power output throughout its entire 25-year service life. ### What is the peak power of a single Panasonic EverVolt panel, and is it suitable for a small roof? EverVolt modules reach up to 410 Wp peak power thanks to the high efficiency of HJT cells, delivering more energy per square meter than conventional PERC panels. This makes them an ideal choice for homeowners with limited roof space who need maximum power density rather than a larger number of lower-efficiency modules. ### How do EverVolt panels perform in winter and overcast conditions typical of Central European climates? HJT technology with N-type cells shows lower efficiency loss at low temperatures compared to standard PERC or BSF cells. On cloudy days, the amorphous silicon layer provides broader spectral absorption, improving performance under diffuse irradiance. The low temperature coefficient of -0.24%/°C also ensures that winter sunlight is harvested efficiently when panel temperatures approach freezing. ### Is the Panasonic EverVolt a bifacial module? No, the Panasonic EverVolt series is a monofacial module — it generates electricity from the front side only. This means no special high-albedo ground surface or elevated racking systems are required, simplifying installation and reducing BoS costs while still delivering the high efficiency characteristic of HJT cell technology. ### Is the Panasonic EverVolt series still available for purchase? The EverVolt series has been discontinued. In April 2025, Panasonic announced a full exit from the solar module and energy storage market. Limited stock may still be available through distributors with existing inventory, but no new units are being manufactured. Panasonic has committed to honoring all warranties for previously sold and installed products. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/evervolt_410_400_datasheet-532c7f6d84e7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, +1.4 pp, +5 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, +1.4 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, +1.4 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, +1.3 pp, +5 yr warranty | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, +1.3 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, +1.2 pp, +5 yr warranty | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +45 W, +1.1 pp, +5 yr warranty | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, hotter, +1.1 pp | | [Panasonic EVPV390HK](https://comparepv.com/panel/panasonic-evpv390hk) | 390 W | -20 W, -1.1 pp | | [Panasonic EVPV400H](https://comparepv.com/panel/panasonic-evpv400h) | 400 W | -10 W, -0.6 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +65 W, +1.8 pp, +15 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +60 W, +1.5 pp, +15 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | +55 W, +1.3 pp, +15 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +30 W, +0.7 pp, +5 yr warranty | | [Maxeon SPR-MAX6-440](https://comparepv.com/panel/maxeon-spr-max6-440) | 440 W | +30 W, +0.6 pp, +15 yr warranty | | [Jetion JT435SYk(B)](https://comparepv.com/panel/jetion-jt435syk-b) | 435 W | +25 W, heavier, +5 yr warranty | --- Source: https://comparepv.com/panel/panasonic-evpv410h 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.
