The use of **Half-Cut technology** and multi-busbar monocrystalline cells significantly reduces energy losses resulting from internal resistance, which translates into more stable operation of the entire installation on hot days. These modules are distinguished by their exceptional resistance to potential-induced degradation and the LID phenomenon, guaranteeing high efficiency over decades of use. For the user, this means the certainty of a quick return on investment and a lower risk of micro-cracks thanks to the **optimized frame design**. This series is dedicated particularly to modern single-family housing, where the deep black of the modules and the elegant appearance of the roof play a key role. Unlike mass-imported products, this series undergoes **triple quality control** directly on the domestic production line, eliminating the risk of hidden manufacturing defects. Thanks to the **self-cleaning coating** and reinforced tempered glass, these panels perform perfectly in conditions of increased dust and under extreme snow loads. It is the ideal solution for those choosing **local technical support** and long-term energy security without any aesthetic compromises. ## Notable figures - At 21.5% efficiency, this panel is on par with typical \*\*N-type 400-450W\*\* modules - 212.8 W/m² power density is 5.5 W/m² below \*\*N-type 400-450W\*\* median (218.3 W/m²) - requires larger installation area - Temperature coefficient of -0.30%/°C matches the \*\*N-type 400-450W\*\* median - #7958 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What does N-type cell technology in the Selfa PREMIUM FULL BLACK series offer, and is the premium worth it? N-type cells are significantly more resistant to LID (Light Induced Degradation) than standard P-type PERC cells. In the PREMIUM FULL BLACK series this means a smaller power drop during the first years of operation and more stable generation throughout the entire 30-year power warranty period. For a 440 Wp module, this translates into measurably more kWh produced over the system's full lifetime — accelerating the return on investment. ### What is the warranty on Selfa PREMIUM FULL BLACK panels and when does coverage start? The PREMIUM FULL BLACK series carries a 20-year product warranty covering physical defects and a 30-year power output warranty. One important practical note: Selfa counts the warranty from the production date, not the purchase date. Before buying, it is worth checking the production date label on the module to confirm how much of the warranty period actually remains. ### Can Selfa PREMIUM FULL BLACK panels handle Polish winters and heavy snow loads? Yes, the PREMIUM FULL BLACK series is designed for the harsh climate conditions typical of Poland. The reinforced tempered glass and optimized frame construction provide high resistance to snow loads. Half-cut multi-busbar monocrystalline cells additionally reduce losses from partial shading — for example from snow accumulated along the bottom edge of a module. ### How do Selfa PREMIUM FULL BLACK panels differ from mass-imported products? The key difference lies in manufacturing location and quality control. Selfa produces modules in Szczecin, Poland, applying triple quality control directly on the domestic production line, eliminating the risk of hidden factory defects. With over 80 years of company history and an authorized service network across Poland, real local technical support is available — without waiting weeks for a response from an overseas manufacturer. ### What is the maximum power of the Selfa PREMIUM FULL BLACK module and how should it be matched to an inverter? The maximum power of a single module in the PREMIUM FULL BLACK series is 440 Wp. When sizing an inverter, check the MPPT voltage range — a typical string of 10 modules at 440 Wp will reach approximately 400–420 V depending on temperature, which is compatible with most standard grid-tied and hybrid inverters available on the Polish market. ### How does the self-cleaning coating on Selfa PREMIUM FULL BLACK panels work, and does it eliminate manual washing? Selfa's SELF-C self-cleaning coating reduces dust and contaminant adhesion to the glass surface — most deposits are removed automatically by rainfall and UV exposure. In typical Polish conditions, panels with this coating require manual cleaning far less frequently than standard modules, reducing O&M costs across the full 30-year operating life of the installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/530-e0eb58a9f9ca.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A480-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a480-mah54mw) | 480 W | +50 W, cooler, +2.6 pp | | [Gokin GK-5-54HG-480M](https://comparepv.com/panel/gokin-gk-5-54hg-480m) | 480 W | +50 W, cooler, +2.6 pp | | [Jinko Solar JKM480N-48QL6-DB-F2-EU](https://comparepv.com/panel/jinko-solar-jkm480n-48ql6-db-f2-eu) | 480 W | +50 W, cooler, +2.5 pp | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +50 W, lighter, +2.5 pp | | [Selfa SV108M.2.4-440](https://comparepv.com/panel/selfa-sv108m-2-4-440) | 440 W | +10 W, +0.5 pp | | [Selfa SV108M.2.4-450](https://comparepv.com/panel/selfa-sv108m-2-4-450) | 450 W | +20 W, heavier, +1.0 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +80 W, cooler, +3.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +65 W, cooler, +3.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +75 W, cooler, +3.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +60 W, cooler, +3.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +70 W, cooler, +3.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +70 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/selfa-sv108m-2-4-430 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
