Space saver, no clear weak spot
The DMEGC INFINITY RT solar panel series introduces a new level of quality to the Polish market through the use of innovative rectangular N-Type TOPCon cells. The use of RT (Rectangular Technology) allows for significantly better utilization of the module surface area, which directly translates into maximizing yields from every square meter of the roof. This is a key solution for investors facing limited mounting space who do not want to sacrifice high system power. These modules stand out with exceptional resistance to light-induced degradation and excellent performance in low-light conditions, which ensures stable energy production throughout the year in the Polish climate. Thanks to their advanced design, this series effectively minimizes energy losses resulting from high ambient temperatures, while offering an enhanced bifaciality factor in bifacial variants. DMEGC INFINITY RT is a proposal for the most demanding residential users and modern commercial projects where long-term profitability and reliability matter. What sets them apart from the competition is the precise combination of record-breaking power density and aesthetic design, making them a standard in the premium segment. By choosing this series, you eliminate the risk of rapid efficiency drops, investing in the technology of tomorrow available today.
Ranking
Signals from the data
Residential and commercial.
Top 20% of the TOPCon 450-500 W segment, against a median of 225.2.
Top 22% of the TOPCon 450-500 W segment, against a median of 22.52%.
The upper efficiency limit of 23.3% exceeds peer comparables by more than 1.8 percentage points versus Jinko Solar JS182MHC120 (21.48%) and by as much as 2.4 percentage points versus Vikram SOMERA (20.91%). In practical terms, this translates to approximately 8–11% more power from the same roof area with an identical number of modules.
The temperature coefficient of Pmax is only −0.29%/°C (ENF Solar data, datasheet DM440-460M10RT), resulting in higher energy yield during summer months compared to older PERC cells (typically −0.35%/°C). Annual degradation after the first year is ≤0.4% — on par with the best-in-class N-type products in this segment.
The manufacturer guarantees at least 87.4% of nominal power output after 30 years of operation (official DMEGC warranty document, PDF 2025-12). None of the peer comparables in the referenced comparison declare a 30-year power warranty, providing a meaningful advantage in NPV calculations for projects with a 25+ year horizon.
DMEGC Solar maintained its BloombergNEF Tier-1 status in Q3 2025, appears on the S&P Global Tier-1 list, and ranked 5th globally in the Wood Mackenzie 2025 ranking. With operations dating back to 1980, installations based on these modules will face no obstacles during bankability due diligence for external project financing.
The rectangular M10RT cells (module dimensions 1762 × 1134 mm, 24.5 kg for the 440–460 W variants) eliminate the inactive corners of conventional square cells, maximizing the utilization of the module's active area. In space-constrained installations, this allows a higher total system power to be achieved without increasing the number of modules.
Certain variants in the series (including DM440-460M10RT-54HBB) carry only a 20-year product warranty, whereas leading Tier-1 manufacturers (Jinko Tiger Neo, LONGi Hi-MO X6) have standardized to a 25-year product warranty across their entire portfolios. The model suffix must be verified prior to purchase — a 5-year difference is material when assessing operational risk.
The analyzed power range (440–465 Wp, is_bifacial: false) does not provide rear-side energy yield (bifacial gain is typically 5–15% on a high-albedo surface). Bifacial INFINITY RT variants in this power range were presented by DMEGC at Intersolar 2024 (pv-magazine.com, June 2024); however, their availability through Polish distribution channels requires confirmation with the local importer.
- Efficiency of 23.0% matches the TOPCon 450-500W median
- At 230.2 W/m² power density, this panel generates 5.0 W/m² more per unit area than TOPCon 450-500W median (225.2 W/m²)
- Temperature coefficient of -0.29%/°C matches the TOPCon 450-500W median
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- Ranked #1919 out of 14005 panels for efficiency in the database
