In practice, it stands out due to the use of modern cell solutions, including **TOPCon type N** variants, which help maintain high operational efficiency over time and better cope with typical losses in rooftop installations. In selected configurations, a **bifacial design** is also available, allowing for the use of light reflected from the ground, which effectively supports energy production in locations where every additional kilowatt-hour counts. S-Nano is a good choice for investors who expect predictable performance in various weather conditions and want to minimize the risk of performance degradation over time. The series is suitable for residential and commercial installations, especially on roofs with difficult exposure, and in locations where **stability of parameters** and **overall system profitability** are important, rather than just theoretical figures. ## Notable figures - Efficiency of 20.6% is 1.1pp above the \*\*PERC 0-400W\*\* median (19.4%) - Power density of 202.1 W/m² packs 7.9 W/m² more into the same footprint vs \*\*PERC 0-400W\*\* median (194.2 W/m²) - Temperature coefficient of -0.34%/°C matches the \*\*PERC 0-400W\*\* median - At 17.8 kg, this panel is 2.7 kg lighter than \*\*PERC 0-400W\*\* median (20.5 kg) - easier handling during installation - Ranked #11275 out of 14129 panels for efficiency in the database ## Questions ### What is TOPCon technology in the Shinson Technology S-Nano panels, and is it worth the premium? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that delivers higher efficiency and lower degradation rates compared to older PERC cells. In the S-Nano series this translates to better performance at high temperatures and reduced power losses over the panel's lifetime. For the investor, it means more energy from the same roof area across decades of system operation. ### What warranty is included with the Shinson Technology S-Nano panels? The S-Nano series comes with a 30-year product warranty covering material and manufacturing defects, plus a 30-year linear power output warranty. Both terms align with premium market standards. To keep the warranty valid, retain your purchase documents and ensure the installation meets the manufacturer's mounting and operating requirements. ### Are Shinson Technology S-Nano panels a good fit for a small roof with limited space? Yes, the S-Nano series was designed specifically for space-constrained installations. TOPCon cell technology delivers higher efficiency per square meter than PERC cells, allowing greater power output from fewer modules. With a maximum power rating of 460 Wp, this series maximizes energy yield even on roofs with a challenging or restricted exposure. ### Is the Shinson Technology S-Nano 460 Wp panel bifacial? No, this variant of the S-Nano series is a monofacial module that generates power from the front side only. It is worth noting that the S-Nano lineup also includes bifacial configurations that capture light reflected from the ground surface. If bifacial technology is a priority for your project, ask your distributor for the appropriate model. ### How do Shinson Technology S-Nano panels perform on hot days and in overcast conditions? The N-type TOPCon cells used in the S-Nano series have a lower temperature coefficient than standard PERC cells, meaning less power loss when the module heats up during summer. N-type technology also performs comparatively well under diffuse light in overcast conditions. Actual energy yield remains strongly influenced by roof tilt angle and the absence of shading. ### Where are Shinson Technology S-Nano panels manufactured, and does the country of origin affect quality? Shinson Technology is a China-based manufacturer with production capacity exceeding 10 GW. The panels carry standard quality certifications (IEC, CE) required for European markets. Chinese PV modules from established manufacturers are widely deployed in installations worldwide. Quality is best assessed through warranty conditions and certifications rather than country of origin alone. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/P1-330-345-Monofacial-Ultra-black-a88493b58a25.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, +2.8 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +2.8 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +2.6 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +2.6 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -40 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -20 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | +20 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | +40 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | +40 W, +2.4 pp, +5 yr warranty | | [Shinson Technology S330M60P1B](https://comparepv.com/panel/shinson-technology-s330m60p1b) | 330 W | -10 W, -1.1 pp | | [Shinson Technology S335M60P1B](https://comparepv.com/panel/shinson-technology-s335m60p1b) | 335 W | -0.8 pp | | [Shinson Technology S345M60P1B](https://comparepv.com/panel/shinson-technology-s345m60p1b) | 345 W | Very close match | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +100 W, cooler, +2.3 pp | | [Jetion JT435SYk(B)](https://comparepv.com/panel/jetion-jt435syk-b) | 435 W | +95 W, cooler, +2.1 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +2.0 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/shinson-technology-s340m60p1b Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
