This structure lets the manufacturer flexibly scale the lineup - from classic panels for residential installations to higher-power, higher-efficiency versions designed for large-scale PV farms and commercial projects. Splitting the cells in half reduces heat losses and internal resistance, helping the modules perform better under partial shading and elevated roof operating temperatures. The lineup also includes **bifacial** Black Frame variants, combining a sleek aesthetic with the ability to capture reflected energy from the rear side of the panel, meaningfully boosting energy yield without expanding the installation footprint. The SV120M series suits investors looking for a proven, budget-friendly PERC solution as well as those ready to invest today in more efficient N-type technology backed by a longer power warranty. It's a flexible product platform that lets you match the panel to the specific project without sacrificing the quality and durability expected from a European manufacturer. ## Notable figures - At 19.5% efficiency, this panel is on par with typical \*\*PERC 0-400W\*\* modules - At 195.6 W/m² power density, roof space requirements are typical for \*\*PERC 0-400W\*\* panels - Temperature coefficient of -0.37%/°C matches the \*\*PERC 0-400W\*\* median - Weight of 18.9 kg (1.6 kg below \*\*PERC 0-400W\*\* median of 20.5 kg) allows easier transport and roof mounting - In the top 90% for efficiency among all PERC panels ## Questions ### Are Selfa SV120M 330W panels still available for purchase? No, the SV120M series has been discontinued by Selfa and is no longer offered as a current production model. Panels may still be found through clearance sales or existing distributor stock, but new production orders are not being fulfilled. When buying, check current inventory availability and confirm that the seller can still honor full warranty support despite the model's discontinuation. ### What is the difference between the PERC and TOPCon variants in the SV120M series? Within the SV120M series, Selfa offered both classic PERC modules and newer versions with TOPCon N-Type cells. The PERC variant, such as this 330 Wp model, is a proven, more budget-friendly option for typical residential installations. TOPCon delivers higher efficiency and slower power degradation over time, but at a higher purchase price - a better fit for investors seeking maximum yield on the same roof area. ### What warranty comes with the Selfa SV120M 330W panel? The SV120M 330W panel comes with a 12-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty. This means the manufacturer commits to maintaining a defined energy production level over a quarter century of use. Even though the series has been discontinued, warranty terms for previously purchased modules remain valid according to the warranty card issued at time of purchase. ### Is the SV120M 330W panel a bifacial module? No, this specific SV120M 330 Wp variant is a monofacial module, using half-cut PERC cells in a standard single-sided configuration only. Bifacial versions with a black frame were available within the same series as a separate variant, allowing extra energy harvest from the rear side of the panel. When selecting a specific unit, check the model designation and datasheet carefully. ### Is Selfa a Tier 1 manufacturer, and where are SV120M panels made? Selfa is a Polish manufacturer headquartered in Poland, but it does not appear on the BloombergNEF Tier 1 manufacturer list. This does not indicate lower module quality - it simply reflects a smaller scale of bankability financing typical of large Asian conglomerates. For individual investors and smaller commercial installations, technical specifications, warranty terms, and certifications matter more than Tier classification alone. ### How does the SV120M panel with half-cut cells perform under partial roof shading? Half-cut cell technology, used in the SV120M, splits a standard cell into two halves, reducing current losses and internal resistance. As a result, the panel handles partial shading better - for example from a chimney, antenna, or neighboring building - since shading one half doesn't fully block the other half's output. In practice, this leads to higher real-world energy yield on typical sloped roofs compared to modules with standard full-size cells. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/297-1a83c9e47fe4.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Cooler, lighter, +3.8 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +3.8 pp | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | -50 W, cooler, +3.8 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +3.6 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.6 pp | | [Heckert Solar ZEUS 3.2 285WP FullBlack](https://comparepv.com/panel/heckert-solar-zeus-3-2-285wp-fullblack) | 285 W | Cooler, +3.6 pp, +5 yr warranty | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | Lighter, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -30 W, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +3.5 pp, +5 yr warranty | | [Selfa SV120M.2-320](https://comparepv.com/panel/tcl-zhonghuan-sv120m-2-320) | 320 W | -10 W, -0.4 pp | | [Selfa SV120M.5.0-330](https://comparepv.com/panel/selfa-sv120m-5-0-330) | 330 W | Very close match | | [Selfa SV120M.5(3)-335](https://comparepv.com/panel/selfa-sv120m-5-3-335) | 335 W | +0.3 pp | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +110 W, cooler, +3.4 pp | | [Jetion JT435SYk(B)](https://comparepv.com/panel/jetion-jt435syk-b) | 435 W | +105 W, cooler, +3.2 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +3.1 pp, +15 yr warranty | | [Jetion JT430SYk(B)](https://comparepv.com/panel/jetion-jt430syk-b) | 430 W | +100 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/selfa-sv120m-5-3-330 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
