The Ecodelta Rays series introduces a new quality to the Polish photovoltaic market, utilizing advanced shingled technology, which eliminates traditional busbars and minimizes gaps between cells. This design directly translates to higher power density and better module efficiency compared to classic solutions with busbar technology. These panels effectively solve the problem of performance drops caused by periodic shading, making them an ideal choice for complex roofs of single-family homes. The innovative construction reduces mechanical stress, providing increased resistance to micro-cracks and extreme weather conditions. For the investor, this means not only higher energy yields but also exceptional full-black aesthetics, where the uniform, dark surface of the modules blends perfectly with modern roofing. Ecodelta Rays stands out from the competition with a reduced risk of hot-spots, which guarantees the safety and longevity of the installation for decades. It is a product aimed at demanding users who expect a combination of technical innovation and elegance, looking for solutions with a low power degradation rate over time. Thanks to precise manufacturing, this series provides a solid foundation for any modern solar power plant, offering maximum return on investment while maintaining the highest visual standards.

What owners get
TOPCon N-type + Shingled Architecture Synergy

Two premium technologies combined in a single module: N-type TOPCon cells exhibit LID degradation below 0.25%/year and effective resistance to LeTID, while the shingled architecture using ECA adhesive instead of solder ribbon eliminates thermal stress and microcracks at interconnection points. The net result is a measurably lower annual degradation rate (~0.4%/year vs. ~0.55%/year for PERC).

Up to 21.2% Efficiency – Top of Its Class

Peak efficiency of 21.2% places the RAYS series directly alongside its peer comparables: AE Solar AURORA (21.28%) and Aptos Solar DNA (21.25%). The sub-0.1 percentage point difference is negligible in residential installations; however, on roof areas with limited space, RAYS delivers power density comparable to the leading 54-cell modules on the market.

Full Black with No Visible Busbars – Premium Aesthetics

Shingled cell technology eliminates visible metallic busbars, producing a uniform black surface with no premium charge for a dedicated all-black product line. For the residential segment with dark roof cladding, this represents a significant aesthetic advantage over conventional silver-framed modules.

Partial Shading Tolerance

Splitting cells into parallel-connected strips (shingled architecture) limits the weakest-link effect: localized shading from a chimney, roof window, or antenna affects only the shaded strip rather than the entire cell string. This is a tangible advantage over conventional half-cut PERC modules without power optimizers on complex roof layouts.

25-Year Linear Power Warranty

The 25-year linear power warranty aligns with the premium market standard and ensures predictable energy yield over the full investment horizon of a prosumer system (SPBT typically 7–12 years). The manufacturer has been active since 2002 (over 20 years), which reduces the risk of warrantor insolvency compared to newer brands.

Trade-offs
Product Warranty Limited to 15 Years

A 15-year product warranty falls below the rising market standard – Jinko Solar Tiger Neo, Trina Vertex S+, and REC Alpha all offer 25-year product warranties. Over a 25-year investment horizon, the 10-year gap means no warranty coverage for potential module defects during the second half of the system's operational life.

Monofacial Only – No Bifacial Option Available

The peer comparable LEDVANCE M395~415P54LM-BF-F3 (415 Wp, 21.25%) offers a bifacial construction, potentially generating an additional 5–15% yield on installations with high-albedo surfaces (white membrane, gravel, snow). The RAYS series does not offer a bifacial variant, which may be a limitation when optimizing ground-mount or flat-roof installations.

Common questions

6 answered
What is the shingled cell technology used in Ecodelta Rays panels and why is it superior to conventional busbars?
In Ecodelta Rays panels, TOPCon cells are cut into narrow strips and overlapped like roof shingles, eliminating traditional busbars entirely. This design allows a greater amount of active cell material to fit within the same module footprint, resulting in higher power density and overall module efficiency. An additional benefit is the elimination of thermal bridging at busbar contacts, which is the primary cause of hot spots and cell microcracks in conventional panel designs.
What warranty does the manufacturer offer on Ecodelta Rays photovoltaic panels?
Ecodelta provides two independent warranties for the Rays series: a 15-year product warranty covering material and manufacturing defects, and a 25-year linear power output warranty guaranteeing minimum generation efficiency over a quarter century. These two levels of protection represent a significant advantage when evaluating the total cost of ownership of a PV installation.
Will Ecodelta Rays 415W panels perform well on a roof with partial shading, for example from a chimney or dormer window?
Yes, the Rays series is particularly well-suited for exactly these types of installations. The shingled cell technology means that shading of a single cell strip reduces the output of the entire module to a far lesser extent than in panels with standard busbars. The integrated bypass circuitry operates at the level of individual cell strips rather than entire strings, which means the annual energy yield on complex residential rooftops is noticeably higher than with conventional half-cut modules.
Are Ecodelta Rays panels available exclusively in a full black finish?
The Rays series is designed primarily with full black aesthetics in mind: a black frame, black backsheet, and dark TOPCon cells create a uniform surface that is difficult to distinguish from modern roofing materials. If a standard silver frame is preferred, it is worth contacting your distributor to inquire about variant availability; however, the full black finish is the flagship and most widely available configuration.
What is the peak power output of the Ecodelta Rays module and how does it compare to average panels available on the Polish market?
The flagship module in the Rays series achieves a peak power output of 415 Wp. By combining TOPCon cells with shingled cell technology, the module efficiency exceeds the level achieved by most popular PERC panels currently on the market. This means that the same roof area accommodates more installed watts, which is particularly important where available roof space is limited.
Where are Ecodelta Rays panels manufactured and where is the company headquartered?
Ecodelta (Eco Delta Power Co., Ltd.) is a brand whose global headquarters is based in France. Rays series panels reach the Polish market through domestic photovoltaic distributors. The manufacturer's European operational presence simplifies warranty claim processing and ensures more responsive after-sales support compared to brands operating solely out of Asia.
