The panels feature **SELF-C self-cleaning surface technology**, allowing rainfall to more effectively wash contaminants off the glass and limiting output losses between maintenance intervals. The **PERC cells with a 5-busbar layout** deliver high energy conversion efficiency and reduced current losses, while the modules are fully **PID-resistant**, ensuring stable system performance throughout the entire service life. A key advantage of the series is its **exclusively positive power tolerance**, meaning the investor actually receives the amount of energy assumed in the project design, without the risk of power shortfall. The reinforced construction with anodized aluminum frames provides high resistance to wind, snow, and hail loads, making these panels a solid choice for both residential microinstallations and larger PV farms. The whole series is backed by a **25-year power warranty** and a nationwide service network, further strengthening the long-term security of the investment. ## Notable figures - Module efficiency of 18.8% is 0.6pp below average for \*\*PERC 0-400W\*\* panels (median: 19.4%) - At 188.2 W/m², this panel generates 5.9 W/m² less per unit area than \*\*PERC 0-400W\*\* median (194.2 W/m²) - Temperature coefficient of -0.37%/°C matches the \*\*PERC 0-400W\*\* median - At 18.5 kg, this panel is 2.0 kg lighter than \*\*PERC 0-400W\*\* median (20.5 kg) - easier handling during installation - In the top 93% for efficiency among all PERC panels ## Questions ### Is the Selfa SV60M.2.1 series still available for purchase? The SV60M.2.1 series has been discontinued and is no longer manufactured by Selfa. Some remaining stock may still be available through distributors, but once depleted, these panels will not be restocked. Anyone planning an installation should ask the manufacturer about a replacement model with similar specifications. ### What warranty comes with Selfa SV60M.2.1 panels? The SV60M.2.1 modules come with a 12-year product warranty and a 25-year linear power warranty. This means the manufacturer guarantees a minimum energy output level for a quarter century, while material or manufacturing defects are covered for 12 years. Selfa's nationwide service network in Poland further supports warranty claims. ### What is SELF-C technology in the SV60M.2.1 panels, and does it really reduce the need for cleaning? SELF-C is a self-cleaning glass surface that allows rain to wash away dust, pollen, and residue more effectively than on standard modules. It doesn't fully eliminate the need for cleaning, especially with heavy debris like construction dust, but it noticeably reduces performance losses between scheduled maintenance, which is particularly useful for hard-to-access roofs. ### Are SV60M.2.1 panels suitable for a roof exposed to heavy snow loads and strong wind? Yes, the modules feature a reinforced frame with anodized aluminum, providing strong resistance to snow load, wind, and hail. The PERC cells with PID resistance also maintain stable performance under significant temperature fluctuations, making this series suitable for both residential rooftops and larger utility-scale PV installations in Poland's climate. ### How does the positive-only power tolerance in SV60M.2.1 differ from standard panels on the market? Many panels have a symmetrical tolerance, such as plus or minus 3 percent, meaning the purchased module could actually generate less power than labeled. The SV60M.2.1 series has a positive-only power tolerance, so actual module output never falls below the rated 325 Wp, giving investors confidence the installation will perform as designed. ### How many cells and busbars do SV60M.2.1 panels use, and how does this affect efficiency? The modules use PERC cells with a 5-busbar layout, which reduces electrical resistance and current losses compared to older 3 or 4-busbar designs. This configuration improves current collection and conduction from each cell, boosting solar energy conversion efficiency while minimizing thermal losses during operation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/309-2de39ebd939d.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, +4.5 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +4.5 pp | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | Cooler, +4.5 pp, +5 yr warranty | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +4.3 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +4.3 pp | | [Heckert Solar ZEUS 3.2 285WP FullBlack](https://comparepv.com/panel/heckert-solar-zeus-3-2-285wp-fullblack) | 285 W | Cooler, +4.3 pp, +5 yr warranty | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | Lighter, +4.2 pp, +5 yr warranty | | [Gamko New Energy GKA182M270W](https://comparepv.com/panel/gamko-new-energy-gka182m270w) | 270 W | Lighter, +4.2 pp, +5 yr warranty | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | Lighter, +4.2 pp, +5 yr warranty | | [Selfa SV120M.5(3)-315](https://comparepv.com/panel/selfa-sv120m-5-3-315) | 315 W | Hotter | | [Selfa SV60M.2.1-320](https://comparepv.com/panel/selfa-sv60m-2-1-320) | 320 W | +0.3 pp | | [Selfa SV120M.5(3)-320](https://comparepv.com/panel/selfa-sv120m-5-3-320) | 320 W | Hotter, +0.5 pp | | [Selfa SV60M.2.1-325](https://comparepv.com/panel/selfa-sv60m-2-1-325) | 325 W | +10 W, +0.6 pp | | [Selfa SV120M.5.0-330](https://comparepv.com/panel/selfa-sv120m-5-0-330) | 330 W | +15 W, +0.8 pp | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +125 W, cooler, +4.1 pp | | [Jetion JT435SYk(B)](https://comparepv.com/panel/jetion-jt435syk-b) | 435 W | +120 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/selfa-sv60m-2-1-315 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
