Thanks to the use of a Multi-Busbar design, these modules offer better current flow and higher resistance to micro-cracks, which directly translates into **a longer period of trouble-free operation** in the demanding Polish climate. This is an ideal choice for investors looking for a balance between high efficiency and mechanical durability, as these panels are characterized by **increased resistance to snow and wind loads**. A special anti-reflective coating allows for effective operation even in low sunlight, which solves the problem of low efficiency on cloudy days. Products in this series are dedicated to both residential and commercial installations, where maximum use of available roof space is key. What sets them apart from the competition is an **excellent temperature coefficient** and rigorous quality control, which guarantees parameter stability for years. By choosing SOMERA, you gain the certainty of **high energy yield at low system costs**, which makes the investment in photovoltaics pay off faster while maintaining the highest fire safety standards. ## Notable figures - 20.0% module efficiency - 0.5pp better than the \*\*PERC 0-400W\*\* median of 19.4% - 199.7 W/m² power density - 5.3 W/m² more than \*\*PERC 0-400W\*\* median (194.4 W/m²), more power per roof area - At -0.35%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - Ranked #12313 out of 14005 panels for efficiency in the database ## Questions ### What is Half-Cut and Multi-Busbar technology in Vikram Solar SOMERA panels, and does it actually make a difference? Half-cut cells are cut in half, so the current flowing through each half-cell is lower, which reduces resistive losses and minimizes the impact of partial shading on the whole module's output. Combined with Multi-Busbar design, current flow improves and resistance to microcracks increases, resulting in higher energy yield and lower failure risk over the panel's long-term operation. ### What warranty comes with the SOMERA 380-410W panels? Vikram Solar provides a 12-year product warranty and a 27-year linear power output warranty, ensuring the PERC cells maintain high efficiency throughout their service life. These are standard terms for a Tier 1 manufacturer from India, though it's worth confirming the current warranty document with your supplier, since this series has already been discontinued from active production. ### Can SOMERA 380-410W panels withstand heavy snow loads and strong wind? Yes, the half-cut cell design combined with Multi-Busbar technology provides enhanced mechanical strength, allowing the modules to better handle snow loads and strong wind gusts compared to conventional panels. This is a key advantage in Poland's climate, where roofs must bear significant snow weight during winter. ### Do SOMERA 380-410W panels perform well in low light and cold temperatures? Yes, a special anti-reflective coating improves the module's response to diffuse and weaker light, translating into better energy production on cloudy days, which are common in Poland. The panels also have a favorable power temperature coefficient (around -0.34%/°C), meaning they lose less power in colder weather than many competing models. ### Are Vikram Solar SOMERA 380-410W panels still available for purchase? The SOMERA 380-410W series has been discontinued from Vikram Solar's current production lineup and replaced by newer, higher-power models. Panels may still be available through distributors as remaining stock, but once inventory runs out they won't be replenished, so it's worth confirming availability and manufacturing date before buying. ### Are the SOMERA 380-410W panels bifacial? No, the SOMERA 380-410W series consists of monofacial modules that generate power only from the front side. If you want extra energy gain from reflected light off the ground, for example on flat roofs with light-colored surfaces, consider bifacial models from Vikram Solar's higher-tier lineup, such as the Somera Grand Bifacial. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Somera-10-108-HC-All-Black-2022-E-R04-2-6d35f772077d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +50 W, cooler, +3.1 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -50 W, lighter, +3.0 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | -30 W, lighter, +3.0 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +3.0 pp, +3 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +3.0 pp, +3 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +3.0 pp, +3 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +3.0 pp, +3 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +50 W, cooler, +2.9 pp | | [Vikram Solar SOMERA VSMHBB.54.380.05](https://comparepv.com/panel/vikram-solar-somera-vsmhbb-54-380-05) | 380 W | -10 W, -0.5 pp | | [Vikram Solar SOMERA VSMHBB.54.385.05](https://comparepv.com/panel/vikram-solar-somera-vsmhbb-54-385-05) | 385 W | -0.3 pp | | [Vikram Solar PARADEA VSMDH.54.AAA.05-395](https://comparepv.com/panel/vikram-solar-paradea-vsmdh-54-aaa-05-395) | 395 W | Heavier, +0.3 pp, +3 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +120 W, cooler, +5.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +105 W, cooler, +4.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +115 W, cooler, +4.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +100 W, cooler, +4.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +110 W, cooler, +4.5 pp | --- Source: https://comparepv.com/panel/vikram-solar-somera-vsmhbb-54-390-05 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
