Unlike standard modules, these products almost completely eliminate negative light-induced degradation phenomena, ensuring stable energy production for many decades. A key differentiator is the **bifacial dual-glass design**, which allows for active energy harvesting from the rear side of the module as well. This allows investors to expect a significantly higher total yield, especially in installations mounted on surfaces with high albedo. These models effectively solve the problem of limited space by generating more power per square meter than traditional counterparts. The utilized **multi-busbar technology and half-cut cells** minimize internal losses and improve resistance to micro-cracks, resulting in trouble-free operation in demanding weather conditions. This series is primarily dedicated to **large-scale photovoltaic farms** and advanced business projects where the lowest levelized cost of energy is crucial. It is distinguished from the competition by its exceptional **mechanical durability and resistance to extreme temperatures**, making it one of the safest investments in the RES sector. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 600-650W\*\* median - At 227.7 W/m² power density, roof space requirements are typical for \*\*TOPCon 600-650W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 600-650W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - Ranked #3073 out of 14005 panels for efficiency in the database ## Questions ### What does N-type TOPCon technology mean in the VSUN N-132BMHR-DG panels and how does it differ from standard P-type cells? N-type TOPCon cells use phosphorus doping instead of boron, which virtually eliminates light-induced degradation (LID) that lowers power output within the first weeks of operation in standard P-type panels. In the N-132BMHR-DG series this results in only 1% power loss in the first year and just 0.4% annually thereafter, ensuring higher and more stable energy yield throughout the system's lifetime. ### How much extra energy do the bifacial dual-glass VSUN N-132BMHR-DG panels generate? The bifacial dual-glass design allows the rear side of the module to capture light reflected from the ground, which can boost total energy yield by up to several percent compared to a standard monofacial panel when installed over bright surfaces such as gravel or white roofing membrane. Actual gain depends on ground albedo, mounting height, and tilt angle, so the best results are achieved in large-scale ground-mounted solar farms, the primary target application for this series. ### What is the warranty on the VSUN N-132BMHR-DG panels and what exactly does it cover? The manufacturer offers a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty with maximum degradation of 1% in the first year and 0.4% annually thereafter. This means that after 30 years the panel should still deliver a significant portion of its original power output, which is an important factor when calculating the payback period of a large photovoltaic investment. ### Are the VSUN N-132BMHR-DG panels suitable for mounting on a single-family home roof? The N-132BMHR-DG series, rated up to 625 Wp, is designed primarily for large-scale solar farms and major commercial installations where the lowest levelized cost of electricity is the priority. The module's large dimensions and dual-glass construction make it heavier and less practical for typical sloped roofs on single-family homes. For residential prosumer applications, smaller and lighter series from the same manufacturer are a better fit. ### Is VSUN a reliable manufacturer to trust for a large-scale investment? VSUN has years of experience manufacturing solar modules and holds UL and CSA 61730 certifications confirming product quality and safety, while a European support office in Germany makes warranty service easier in our market. However, the manufacturer does not always appear in classic Tier-1 rankings, so for large-scale projects it is worth additionally verifying the company's current financial standing and references through your distributor. ### How do the VSUN N-132BMHR-DG panels perform in high temperatures and harsh weather conditions? Thanks to multi-busbar technology and half-cut cells, the modules have lower resistive losses and a better temperature coefficient than standard P-type panels, meaning less power drop in high ambient temperatures. The dual-glass construction also increases mechanical resistance to snow load, wind, and microcracks, making this series well suited for installations operating in demanding climate conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/663b24645bbf8-598176f842c7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR8-66HVD-665M](https://comparepv.com/panel/longi-lr8-66hvd-665m) | 665 W | +50 W, cooler, +1.9 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (665W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-665w-class) | 665 W | +50 W, cooler, +1.9 pp | | [Huayao HY665-B144DSS](https://comparepv.com/panel/huayao-hy665-b144dss) | 665 W | +50 W, lighter, +1.9 pp | | [Sunpro Power SPDG665-BC132R12](https://comparepv.com/panel/sunpro-spdg665-bc132r12) | 665 W | +50 W, cooler, +1.9 pp | | [VSUN VSUN600N-132BMHR-DG](https://comparepv.com/panel/vsun-vsun600n-132bmhr-dg) | 600 W | -15 W, -0.6 pp | | [VSUN VSUN605N-132BMHR-DG](https://comparepv.com/panel/vsun-vsun605n-132bmhr-dg) | 605 W | -10 W, -0.4 pp | | [VSUN VSUN610N-132BMHR-DG](https://comparepv.com/panel/vsun-vsun610n-132bmhr-dg) | 610 W | Very close match | | [VSUN VSUN620N-132BMHR-DG](https://comparepv.com/panel/vsun-vsun620n-132bmhr-dg) | 620 W | Very close match | | [VSUN VSUN625N-132BMHR-DG](https://comparepv.com/panel/vsun-vsun625n-132bmhr-dg) | 625 W | +10 W, +0.4 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +60 W, lighter, +2.2 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +85 W, cooler, +2.2 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +80 W, cooler, +2.1 pp | --- Source: https://comparepv.com/panel/vsun-vsun615n-132bmhr-dg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
