On a 10 MWp project this translates to approximately 3,000 fewer modules versus the 500 Wp class, cutting structural, cabling, and labor balance-of-system (BoS) costs by an estimated 5–8% and directly improving project LCOE. - **21.6% efficiency — peer best-in-class** - The 670 Wp variant reaches 21.6% module efficiency, matching Hiwatt Solar HW-M12/132H (670 W, 21.6%) and outperforming both ZNShine ZXM8-TP132 (21.57%) and Techwise Solar Summit Series (21.57%). The series holds the top position within its peer-comparable group with no efficiency penalty. - **Half-cut + multi-busbar — lower I²R losses** - Halving the cell reduces operating current 2×, cutting I²R resistive losses by approximately 75% versus full cells. Multi-busbar interconnects shorten the current path, improve microcrack tolerance, and enhance performance under partial shading conditions. - **PID resistance + IP68 + IEC 61215/61730** - The module carries certified potential-induced degradation (PID) resistance, essential for DC systems above 1,000 V. The IP68-rated junction box combined with IEC 61215 and IEC 61730 certifications confirms mechanical and electrical durability in demanding climatic environments. ## Cons - **Not on BNEF Tier-1 bankable list** - JS Solar does not appear on the BloombergNEF bankable manufacturer list (Q1/Q2 2026), while peer competitor ZNShine Solar is included. Non-recourse financing for utility-scale projects typically mandates Tier-1 modules; absent that status, lenders may require additional credit enhancements or decline project financing outright. - **P-type PERC: higher LID/LeTID vs. N-type** - PERC cells lose 1.5–3% of rated power to LID (boron-oxygen defect) in the first hours of exposure and a further 0.5–1.5% to LeTID, with annual degradation of ~0.50–0.55%/yr. Competing N-type TOPCon modules (Jinko Tiger Neo, JA Solar DeepBlue 4.0, Trina Vertex N) exhibit LID \<0.5% and annual degradation of 0.35–0.40%/yr. TOPCon has become the dominant utility-scale standard in 2026, reducing the technological appeal of the JS210MHC132 series. - **Monofacial only — no bifacial option** - The series lacks a bifacial variant. Ground-mount utility projects with bifacial modules capture an additional 5–15% energy yield from albedo reflection, directly lowering LCOE. The absence of this option limits the series' competitiveness against dual-offering product lines and may disqualify it from tenders that specify bifacial as a technical minimum. ## About this series The JS Solar JS210MHC132 series is an advanced solution based on **210 mm cell technology**, which redefines the efficiency of modern photovoltaic installations. The use of large silicon wafers combined with **Half-Cut design and Multi-busbar technology** allows for a significant reduction in resistance losses and better performance under partial shading conditions. These modules effectively solve the problem of limited installation space by offering exceptionally high power density, which directly translates into lower total system costs (BOS) by reducing expenditures on structures and cabling. They are characterized by **high resistance to mechanical loads** and a minimized light-induced degradation effect, which guarantees stable production of clean energy for decades. They are primarily intended for commercial investors and solar farm developers, where the priority is to maximize profit from every installed kilowatt. Robust construction and an **optimized temperature coefficient** ensure that these panels maintain high efficiency even on hot days, distinguishing them from standard solutions and making them a leader in cost-effectiveness in the large-scale installation segment. ## Notable figures - Module efficiency of 20.9% is 0.9pp below average for \*\*database\*\* panels (median: 21.8%) - Power density of 209.2 W/m² is 8.8 W/m² below \*\*database\*\* median (218.1 W/m²) - needs more roof space - At -0.34%/°C, loses 0.04pp more power per degree than \*\*database\*\* median (-0.30%/°C) - At 34.0 kg (7.5 kg above \*\*database\*\* median of 26.5 kg), requires checking roof load capacity - #10072 for efficiency, #8778 for temperature performance out of 14005 panels ## Questions ### What is the power output warranty period for JS Solar JS210MHC132 panels? The JS Solar JS210MHC132 series comes with a 25-year linear power output warranty. This means the manufacturer guarantees the module will maintain a specified performance level throughout that period. For commercial installations and solar farms, such a long warranty horizon is critical when calculating the return on investment and projecting energy yield revenues. ### What are the practical benefits of half-cut cell and multi-busbar technology in the JS210MHC132 series? In the JS210MHC132 series, half-cut technology splits 132 large 210 mm cells in half, reducing the working current and cutting resistive losses by several percentage points. The 12-busbar (12BB) design shortens the electron path to the busbars, improving current collection and reducing thermal stress. The net result is higher module efficiency and improved performance under partial shading conditions. ### Are JS Solar JS210MHC132 panels suitable for large commercial installations or utility-scale solar farms? Yes, the JS210MHC132 series is designed specifically for commercial and utility-scale projects. With up to 670 Wp per module, its high power density means fewer panels and fewer mounting structures per kWp installed, which directly reduces BoS costs. The combination of high mechanical durability and optimized system costs makes this series particularly cost-effective at scale. ### How do JS210MHC132 panels perform on hot days with high ambient temperatures? The JS210MHC132 series features an optimized temperature coefficient of Pmax typical for 210 mm monocrystalline cells (approx. -0.34%/°C). In practice, this means a lower power drop compared to standard modules during peak summer heat. For investors in southern regions, this translates into measurably more kilowatt-hours generated during the hottest months of the year. ### Is the JS Solar JS210MHC132 series a bifacial panel? No, the JS210MHC132 is a monofacial module — it captures solar irradiance from the front side only. This means no special high-albedo ground surface is required and no additional albedo modeling is needed during system design. It also typically results in a lower per-unit cost compared to bifacial modules of similar rated power. ### Is JS Solar a Tier 1 manufacturer, and what does that mean for buyers? JS Solar is not currently listed as a Tier 1 manufacturer by agencies such as BloombergNEF. For buyers, this means that some financial institutions may require additional due diligence when bank-financing a project. It is advisable to verify the availability of a product warranty insurance policy and review references from other investors who have deployed this series in comparable projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JS210MHC132-670W-c8f9e3b4b42a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +4.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +4.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +50 W, cooler, +4.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, +4.0 pp, +5 yr warranty | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +3.9 pp | | [JS Solar JS210MHC132-655](https://comparepv.com/panel/js-solar-js210mhc132-655) | 655 W | +0.2 pp | | [JS Solar JS210MHC132-660](https://comparepv.com/panel/js-solar-js210mhc132-660) | 660 W | +10 W, +0.3 pp | | [JS Solar JS210MHC132-665](https://comparepv.com/panel/js-solar-js210mhc132-665) | 665 W | +15 W, +0.5 pp | | [JS Solar JS210MHC132-670](https://comparepv.com/panel/js-solar-js210mhc132-670) | 670 W | +20 W, +0.7 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +155 W, cooler, +4.2 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +150 W, cooler, +4.0 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +145 W, cooler, +3.9 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +140 W, cooler, +3.7 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +110 W, cooler, +3.6 pp | --- Source: https://comparepv.com/panel/js-solar-js210mhc132-650 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
