This meaningfully lowers the installation's lifetime LCOE. - **Glass-glass construction and bifacial design** - The dual-glass build protects the N-type TOPCon cells from moisture and micro-cracks, while bifaciality of up to 85% captures reflected light off the ground, boosting yield without increasing installation footprint. - **Mechanical resilience in harsh conditions** - The reinforced frame withstands snow loads up to 8,000 Pa and wind loads up to 5,400 Pa, making the series a solid choice for demanding climate regions. - **Wide power range across 25 variants** - Ratings from 430 Wp to 710 Wp across 25 variants allow the series to fit residential rooftops as well as commercial and utility-scale PV installations without switching cell technology. ## Cons - **Higher degradation than HJT competitors** - N-type TOPCon cells degrade faster (roughly 0.40%/year) than the HJT technology used by comparable peer Heliene 132HC G12 HJT SL Bifacial (roughly 0.25%/year), meaning that despite similar starting efficiency (23.22% vs 22.86%), retained capacity over 25-30 years will be lower. ## About this series The PVolution CORE series is built for anyone who expects more than just high output from their solar panels - durability measured in decades matters just as much. The modules are based on **N-Type TOPCon cells**, delivering more stable performance at high temperatures and slower degradation compared to older PERC technology. The **glass-glass construction** shields the cells from moisture and microcracks, allowing the panels to retain a high share of their rated power even after thirty years of operation. The **bifacial, dual-glass design** also captures light reflected off the roof or ground, meaningfully boosting energy yield without increasing installation footprint. CORE series panels are available in several power variants, making them a good fit for residential rooftops as well as commercial installations and utility-scale solar parks. Their **reinforced frame and resistance to snow and wind loads** make them a solid choice in more demanding climate conditions. This is a solution for investors who value predictable returns, a low LCOE over the full lifetime of the installation, and the confidence that the panel will keep performing reliably long after competing products' warranty periods have ended. ## Questions ### How does TOPCon cell technology in PVolution CORE panels differ from older PERC panels? The N-Type TOPCon cells used in the CORE series have a lower annual degradation rate and perform better at high temperatures than P-Type PERC cells. In practice, this means the panel loses less power on hot days and ages more slowly over the years, resulting in higher energy yield throughout the 30-year warranty period. ### Does the bifacial glass-glass design of CORE panels actually increase energy production? Yes, the glass-glass bifacial construction allows the rear side of the module to capture light reflected from the roof, bright ground surfaces, or snow. Depending on the albedo of the mounting surface and installation height, the additional energy gain can range from a few to over a dozen percent compared to a monofacial panel of the same rated power, without increasing roof area. ### What warranty comes with PVolution CORE panels and what does it cover? The CORE series comes with a 30-year product warranty and a 30-year linear power output warranty. This means the manufacturer guarantees both build quality and retention of a high percentage of rated power over three decades, a much longer period than the standard 10-15 years offered on older PERC generation panels. ### Are 710 Wp CORE panels suitable for a residential rooftop installation? Yes, despite the high power output of up to 710 Wp, the CORE series is available in several power variants, so you can choose a module suited to a small rooftop system as well as a large-scale solar farm. The reinforced frame also provides resistance to snow and wind loads, making it a safe choice for demanding climate conditions typical of many rooftops. ### Is the glass-glass construction of CORE panels more resistant to microcracks than a standard framed backsheet panel? Yes, the dual-glass design better protects the cells from moisture and mechanical stress than a traditional backsheet construction. This lowers the risk of microcracks forming during transport, installation, or due to thermal stress, helping the panel retain its original performance longer, as reflected in the extended power warranty. ### Is it worth paying more for bifacial TOPCon panels instead of a cheaper PERC panel? Choosing CORE panels makes sense for investors who evaluate energy cost over the full lifecycle of the installation, not just the upfront price. Lower annual degradation, additional yield from the bifacial effect, and a 30-year warranty reduce LCOE over the long term, despite a higher initial price compared to classic PERC panels with 10-15 year warranties. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/CORE430-450N96R12-b93f352476b8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, cooler, +2.2 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, cooler, +2.2 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, cooler, +2.0 pp | | [PVolution PVN430-R12TCBB](https://comparepv.com/panel/pvolution-pvn430-r12tcbb) | 430 W | -15 W, -0.8 pp | | [PVolution PVN435-R12TCBB](https://comparepv.com/panel/pvolution-pvn435-r12tcbb) | 435 W | -10 W, -0.5 pp | | [PVolution PVN440-R12TCBB](https://comparepv.com/panel/pvolution-pvn440-r12tcbb) | 440 W | -0.2 pp | | [PVolution PVN450-R12TCBB](https://comparepv.com/panel/pvolution-pvn450-r12tcbb) | 450 W | +0.2 pp | | [PVolution PVN455-R12TCBB](https://comparepv.com/panel/pvolution-pvn455-r12tcbb) | 455 W | +10 W, +0.5 pp | | [PVolution PVN460-R12TCBB](https://comparepv.com/panel/pvolution-pvn460-r12tcbb) | 460 W | +15 W, +0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +2.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/pvolution-pvn445-r12tcbb Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
