For investors in Poland, this may mean limited access to warranty service and replacement parts compared to Tier-1 manufacturers with established European distribution networks. - **No bifacial technology** - Unlike the comparable Luxor Solar Eco Line N-type TOPCon Glass-Glass Bifacial (410–430W, 21.33% efficiency), the ECONOROOTS series is monofacial, ruling out the additional energy yield from albedo reflection possible with installations on light-colored surfaces or elevated racking. - **Wide power spread within the series** - A power range of 230–410 Wp across only 3 variants suggests some models are based on older, lower power-density cell formats than the standard 410W+ modules now offered by peers such as VDS Renewable and Sunket, which can complicate matching a single product line to modern mounting systems. ## About this series The Kyocera ECONOROOTS series focuses on maximizing durability through the use of a unique, patented duralumin frame construction, which ensures exceptional mechanical stability of the entire module. The silicon cells used in this line undergo a precise surface texturing process, which allows for significantly more efficient light absorption even at less favorable angles of sunlight. This solves the key problem of performance drops on cloudy days, making the home installation a more predictable energy source throughout the year. ECONOROOTS stands out from the competition with an **integrated mounting system**, which effectively minimizes the risk of harmful cell micro-cracks during installation and long-term operation in harsh weather conditions. It is a solution dedicated primarily to homeowners seeking **reliability confirmed by decades of market experience**. Thanks to **high resistance to static loads**, these panels perform perfectly in the Polish climate, especially in regions with heavy snowfall. By choosing this series, the investor receives **Japanese precision of workmanship**, which eliminates the problem of rapid power degradation characteristic of many cheaper alternatives. This technology is created for conscious users who prioritize the financial certainty of their investment over temporary market trends. ## Notable figures - Efficiency of 21.0% is 0.8pp below the \*\*database\*\* median (21.8%) - At 210.0 W/m², this panel generates 8.1 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - Weight of 25.4 kg (1.1 kg below \*\*database\*\* median of 26.5 kg) allows easier transport and roof mounting - #9758 for efficiency, #13924 for temperature performance out of 14005 panels ## Questions ### Are Kyocera ECONOROOTS panels suitable for Polish climate conditions with heavy snowfall? Yes, the ECONOROOTS series is engineered for high static load resistance, making it a strong choice for snow-heavy regions of Poland such as Podhale or the Sudeten Mountains. The duralumin frame provides exceptional structural rigidity, keeping the module mechanically intact under a heavy snow load and minimizing the risk of microcracks in the solar cells. ### What is the maximum power output of the Kyocera ECONOROOTS panel and is it enough for a typical home installation? The Kyocera ECONOROOTS panel delivers a peak power output of 410 Wp. For an average single-family home consuming roughly 4,000 kWh per year, 8 to 12 modules are typically sufficient, resulting in a system between 3.3 and 4.9 kWp. This covers full energy demand during summer months and significantly reduces utility bills year-round. ### Is the Kyocera ECONOROOTS a bifacial module? No, the ECONOROOTS series is a monofacial module that generates power from the front surface only. It does not require a light-colored roofing substrate or elevated racking for bifacial gain, which simplifies installation and lowers balance-of-system (BoS) costs. For a standard pitched roof with tiles or metal sheeting, a monofacial module is fully adequate and more cost-effective than a bifacial alternative. ### How does ECONOROOTS surface texturization affect performance on overcast days? The precision surface texturization of the silicon cells allows diffuse light under cloud cover to be absorbed far more efficiently than on flat-surface cells. In practical terms, this means lower output losses on typical overcast Polish days and a more predictable annual energy yield. This is especially relevant at Polish latitudes, where clear-sky days are relatively scarce throughout the year. ### Is the Kyocera ECONOROOTS integrated mounting system compatible with standard racking hardware available in Poland? The ECONOROOTS integrated mounting system is designed to work with standard aluminum and steel rail systems widely available from Polish distributors. The key advantage of this design is reduced point stress during installation, lowering the risk of cell microcracks. However, it is recommended to consult a certified PV installer to select the correct accessories for your specific roof type before proceeding. ### What warranty does Kyocera offer on the ECONOROOTS series and what is the difference between a product warranty and a power output warranty? As a Japanese manufacturer with decades of market experience, Kyocera typically provides a product warranty covering material and workmanship defects, alongside a separate linear power output warranty guaranteeing that the panel retains at least 80% of its rated power after 25 years. The product warranty covers physical module defects, while the power output warranty protects against excessive power degradation over time. Exact terms should be verified in the current manufacturer documentation or through an authorized distributor. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1-171fe9464291.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, lighter, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, lighter, +2.6 pp | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, lighter, +2.6 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, lighter, +2.5 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, lighter, +2.5 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, +2.4 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +45 W, lighter, +2.3 pp | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, lighter, +2.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, lighter, +4.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +85 W, lighter, +3.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +95 W, lighter, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +80 W, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +90 W, lighter, +3.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +90 W, lighter, +3.5 pp | --- Source: https://comparepv.com/panel/kyocera-kt410w-108hl4 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
