Middle of its segment, weak in heat
The Ecodelta Classic M10 series is a modern solution based on 182 mm cell technology, which ensures an optimal balance between high efficiency and standard module dimensions. The use of Half-Cut construction significantly reduces energy losses resulting from internal resistance, which directly translates into higher yields even in more difficult lighting conditions or with partial roof shading. This is a key advantage for domestic installations, where architectural elements often limit direct sun exposure. This series stands out for its high mechanical resistance to extreme snow and wind loads, which guarantees stable operation in the variable Polish climate for decades. Classic M10 panels are an excellent choice for investors looking for reliability at an affordable price, without having to give up the latest engineering achievements. Thanks to the optimized temperature coefficient, these modules work more efficiently during hot days compared to older types of cells. This is a solution dedicated to prosumers and entrepreneurs who focus on a quick return on investment while maintaining the highest safety standards. In this series, Ecodelta combines aesthetic workmanship with solid performance, making it one of the most cost-effective propositions on the market.

Hot climates, tight roof space and roofs where every square metre has to count.
Bottom 2% of the TOPCon 550-600 W segment, against a median of -0.290. Ranked 10,419th in the whole database.

The top efficiency in the series (21.31%) is virtually identical to direct competitors: Goldi Solar GS10-B144-TF (21.3%), IBC Solar 182M Half Cell (21.28%), and S-Energy SL65-72BGJ (21.3%). The series surrenders no efficiency points relative to comparable products on the market.
The half-cut cell design splits each cell in two, reducing operating current by ~50% and lowering internal resistive losses. Under typical residential rooftop conditions with partial shading (chimney, dormer, antenna), this translates into a measurable increase in annual energy yield compared to full-cell modules of the same rated power.
The availability of five power bins in 5 Wp increments allows precise matching of module count to roof area and inverter input limits, minimizing string mismatch losses.
The 182 mm half-cut segment typically meets IEC 61215 load ratings of up to 5,400 Pa for snow and 2,400 Pa for wind, which is adequate for the extreme winter conditions found across Poland's snow load zones I–III.
A 25-year linear power output warranty is the market-standard for this class, covering the typical lifecycle of a residential PV system and ensuring project bankability for third-party financing.
P-type PERC cells exhibit annual degradation of ~0.6–0.8% and first-year LID of ~2%, whereas N-type TOPCon achieves ~0.4–0.5%/year and ~1% LID respectively. Over a 25-year project lifetime, this gap translates into meaningfully lower cumulative energy yield. The market in 2025–2026 is shifting decisively toward TOPCon – while peer comparables in this price segment also use PERC, making this a technology-class limitation rather than a differentiating weakness, the constraint remains real.
Leading module manufacturers (Trina Solar, LONGi, JA Solar) have moved to 12–15-year product warranties, with 15 years emerging as the new benchmark for the premium tier. The 12-year product warranty on the ECODELTA Classic M10 may be a disadvantage in competitive tender evaluations within the commercial segment.
