The use of **multi-busbar technology** reduces internal power loss and lowers the risk of failure caused by microcracks and broken busbars, resulting in greater panel durability under demanding operating conditions. By splitting the cells in half, the module offers significantly improved resistance to hot-spot effects caused by shading, an important advantage for roof installations with partial shading from chimneys or trees. The panels feature **high PID resistance**, translating into higher energy yield over the system's lifetime and a lower LCOE. Tempered 3.2mm glass with an anti-reflective coating delivers solid **low-light performance**, while certified resistance to high wind and snow loads makes the series suitable for demanding climate zones. The aesthetic full black version makes RS7K-M a fitting choice for both commercial projects and residential rooftops, where the visual appearance of the installation matters just as much as its performance. ## Notable figures - Module efficiency of 19.8% is 2.0pp below average for \*\*database\*\* panels (median: 21.8%) - Power density of 197.6 W/m² is 20.5 W/m² below \*\*database\*\* median (218.1 W/m²) - needs more roof space - -0.34%/°C temperature coefficient - 0.04pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - At 19.5 kg, this panel is 7.0 kg lighter than \*\*database\*\* median (26.5 kg) - easier handling during installation - Ranked #12416 out of 14005 panels for efficiency in the database ## Questions ### What is the maximum power output of the RS7K-M series panels and how is it achieved? The RS7K-M series panels reach a maximum power output of up to 380 Wp. This is achieved through monocrystalline half-cut cells with 9BB (multi-busbar) technology, which reduce resistive losses and increase conversion efficiency compared to older modules with fewer busbars. ### What warranty comes with Resun Solar RS7K-M panels? The manufacturer provides a 12-year product warranty and a 30-year linear power output warranty. This means that after 30 years of operation, the panel should still generate a guaranteed percentage of its initial output, making this series suitable for long-term investments, including commercial installations. ### Are RS7K-M panels suitable for roofs partially shaded by chimneys or trees? Yes, thanks to half-cut cell technology, in which cells are split into halves, the module handles partial shading much better. The cells operate in smaller, independent circuits, which reduces the risk of the hot-spot effect and limits the impact of shading on total energy output. ### Do RS7K-M panels perform well in low-light conditions, such as autumn or winter? Yes, the panels feature 3.2 mm tempered glass with an anti-reflective coating that improves absorption of diffused light in cloudy weather and at low sun angles. This results in more stable energy production during periods of lower solar irradiance, such as autumn and winter. ### How does the multi-busbar technology in RS7K-M differ from standard 5BB panels? The 9BB multi-busbar technology used in RS7K-M increases the number of current-carrying paths on the cell surface compared to older 5BB modules. This reduces internal power losses, lowers the risk of busbar breakage and microcracks, and improves panel durability under demanding operating conditions such as thermal cycling and mechanical stress. ### Are RS7K-M panels resistant to heavy snow and wind loads? Yes, the RS7K-M series has certified resistance to high mechanical loads from snow and wind, confirmed through standard industry testing. This makes the modules suitable for installations in regions with more demanding climate conditions, including areas with heavy winter snowfall. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/RS7K-M-355-380W-min-1b3196b1c5c2.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, +3.3 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, +3.3 pp, -5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -40 W, lighter, +3.2 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -20 W, lighter, +3.2 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.2 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | +20 W, lighter, +3.2 pp | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +40 W, lighter, +3.2 pp | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +40 W, lighter, +3.2 pp | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | +20 W, lighter, +3.2 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +2.8 pp, +10 yr warranty | | [Resun Solar RS7K-355M](https://comparepv.com/panel/resun-solar-rs7k-355m) | 355 W | -0.3 pp | | [Resun Solar RS7K-365M](https://comparepv.com/panel/resun-solar-rs7k-365m) | 365 W | Very close match | | [Resun Solar RS7K-370M](https://comparepv.com/panel/resun-solar-rs7k-370m) | 370 W | +10 W, +0.5 pp | | [Resun Solar RS7K-375M](https://comparepv.com/panel/resun-solar-rs7k-375m) | 375 W | +15 W, +0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +150 W, cooler, +5.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +135 W, cooler, +5.0 pp | --- Source: https://comparepv.com/panel/resun-solar-rs7k-m-360w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
