Thanks to the use of **210 mm silicon wafers**, these modules offer significantly higher power density than standard market solutions, allowing for better utilization of available space. A key advantage of the series is its exceptionally low temperature coefficient, ensuring the panels maintain high efficiency even on hot days, minimizing thermal energy losses. The bifacial design enables **energy generation from both sides of the module** by utilizing light reflected from the ground, which is particularly important in ground-mounted installations and on roofs with light-colored coverings. This series completely eliminates light-induced degradation (LID) and potential-induced degradation (PID) issues, guaranteeing investors long-term yield stability. It is an ideal choice for those seeking **maximum efficiency from limited roof area** or LCOE cost optimization in large farm projects. They stand out from the competition due to an innovative approach to **connecting cells with seamless technology**, which reduces mechanical stress and significantly increases the lifespan of the entire system in demanding Polish weather conditions. ## Notable figures - Module efficiency of 22.5% is 0.5pp below average for \*\*HJT 700-750W\*\* panels (median: 23.0%) - Power density of 225.3 W/m² is 4.9 W/m² below \*\*HJT 700-750W\*\* median (230.2 W/m²) - needs more roof space - Temperature coefficient of -0.24%/°C matches the \*\*HJT 700-750W\*\* median - 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces - Ranked #4222 out of 14005 panels for efficiency in the database ## Questions ### How does HJT technology in the Twinsel 210 Heterojunction Module series differ from standard PERC or TOPCon cells? HJT (heterojunction) cells combine a crystalline silicon layer with thin amorphous silicon layers, reducing carrier recombination and boosting efficiency compared to PERC. Unlike TOPCon, HJT has a lower temperature coefficient and a symmetrical structure, allowing the panel to perform well on both sides. In the Twinsel 210 series, this translates into higher energy yield per unit of roof area. ### What warranty comes with the Twinsel 210 Heterojunction Module panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 30-year power performance warranty. This means the module should retain a guaranteed percentage of its original rated power over three decades, outperforming the standard 25-year power warranties typically offered with PERC technology. ### Are the bifacial Twinsel 210 HJT panels suitable for ground-mount or flat-roof installations? Yes, the glass-glass bifacial design generates additional energy from the rear side of the module using light reflected off the ground surface, which works best on ground-mount structures or flat roofs with light-colored surfaces such as gravel or PVC membrane. On sloped roofs with dark shingles, the bifacial gain will be smaller, but the panel will still operate normally on its front side. ### Do the Twinsel 210 Heterojunction panels perform well in high summer temperatures? Yes, this is one of the key advantages of the HJT technology used in this series. A low temperature coefficient means the panel loses less power as cell temperature rises compared to PERC or polycrystalline modules. In practice, this results in more stable energy output on hot days and lower losses relative to competing products on the market. ### Is Twinsel Electronic Technology a Tier 1 manufacturer, and is it worth buying panels outside that list? Twinsel does not currently appear on the Bloomberg NEF Tier 1 manufacturer list, which mainly reflects the scale of bank financing rather than product quality itself. The company has operated since 2011 and specializes in HJT cell production. When purchasing, it is worth focusing on warranty terms, certifications (IEC, TÜV), and distributor reliability rather than Tier 1 status alone. ### What is the maximum power output of a single panel in the Twinsel 210 Heterojunction Module series? Panels in this series reach a maximum power of up to 700 Wp, based on a large-format module with 132 half-cut cells and 210 mm wafers. This high per-panel output reduces the number of modules needed to reach a target system size, lowering installation costs and the number of connections in the system. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/TSM132-8-675-700BHDG-ca580298ecc0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -50 W, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Hotter, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -25 W, lighter, +2.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Hotter, lighter, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Hotter, lighter, +2.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -30 W, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -30 W, lighter, +2.3 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -30 W, lighter, +2.3 pp | | [Twinsel Electronic Technology TSM132-8-675-700BHDG (675W variant)](https://comparepv.com/panel/twinsel-electronic-technology-tsm132-8-675-700bhdg-675w-variant) | 675 W | -25 W, -0.6 pp | | [Twinsel Electronic Technology TSM132-8-675-700BHDG (680W variant)](https://comparepv.com/panel/twinsel-electronic-technology-tsm132-8-675-700bhdg-680w-variant) | 680 W | -20 W, -0.4 pp | | [Twinsel Electronic Technology TSM132-8-675-700BHDG (685W variant)](https://comparepv.com/panel/twinsel-electronic-technology-tsm132-8-675-700bhdg-685w-variant) | 685 W | -15 W, -0.3 pp | | [Twinsel Electronic Technology TSM132-8-675-700BHDG (690W variant)](https://comparepv.com/panel/twinsel-electronic-technology-tsm132-8-675-700bhdg-690w-variant) | 690 W | -10 W, -0.3 pp | | [Twinsel Electronic Technology TSM132-8-675-700BHDG (695W variant)](https://comparepv.com/panel/twinsel-electronic-technology-tsm132-8-675-700bhdg-695w-variant) | 695 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +105 W, hotter, +2.6 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +100 W, hotter, +2.4 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +95 W, hotter, +2.3 pp | --- Source: https://comparepv.com/panel/twinsel-electronic-technology-tsm132-8-700bhdg Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
