Space saver, no clear weak spot
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.
Ranking
Signals from the data
Commercial and utility-scale.
Top 17% of the TOPCon 550-600 W segment, against a median of 224.4.
Top 19% of the TOPCon 550-600 W segment, against a median of 22.44%.
The CORE series' peak efficiency (23.22%) exceeds comparable 710 Wp modules from competitors, such as Goldi Solar HELOC PLUS G12 (22.85%) and Talesun TM8G66M (22.9%), delivering higher energy yield on the same roof area.
The 30-year power warranty exceeds the market standard for TOPCon, where most Tier-1 manufacturers offer 25 years with retention around 84-86%. This meaningfully lowers the installation's lifetime LCOE.
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.
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.
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.
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.
- At 22.8% efficiency, this panel is on par with typical TOPCon 550-600W modules
- 228.4 W/m² power density - 4.0 W/m² more than TOPCon 550-600W median (224.4 W/m²), more power per roof area
- Temperature coefficient of -0.30%/°C matches the TOPCon 550-600W median
- 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces
- #2738 for efficiency, #6152 for temperature performance out of 14129 panels

Datasheet charts
Measured curves published by PVolution in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 590 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
Model: bifaciality × albedo × 0.6 view factor. A first-order estimate, not a yield simulation.
