For utility-scale PV farms above 1 MWp, estimated BoS savings versus conventional 400 Wp modules are 6–8%, reducing LCOE. - **Temperature coefficient of -0.34%/°C** - A Pmax temperature coefficient of -0.34%/°C places this series at the better end of P-type Mono PERC modules (typical class range: -0.35 to -0.40%/°C). At a cell temperature of 65°C (typical summer day in Central Europe), power loss is ~17% versus ~22% for modules rated at -0.44%/°C. - **25-year product and power warranty** - JS Solar guarantees a minimum of 84.8% of rated power output after 25 years, alongside a 25-year product workmanship warranty. This is the full premium-segment standard for Mono PERC modules in the 540–560 Wp class. ## Cons - **Not BNEF Tier-1 bankable** - JS Solar does not appear on the BNEF Tier-1 Bankable Manufacturers list (Q1 2026). This disqualifies the series from non-recourse financed projects, where institutional lenders standardly mandate Tier-1 modules. Practical use is therefore limited to self-funded commercial installations and residential prosumer systems. - **Efficiency below direct peer comparables** - Maximum module efficiency of 21.4% trails direct peers by 0.3 percentage points — Exiom EX540-560M(B) and Fellow Energy FE72-18X both achieve 21.7% at the same 560 Wp power ceiling. For a 100 kWp array, the gap translates to approximately 1–2 m² of additional mounting area required. - **P-type Mono PERC, not N-type** - The JS210MHC110 uses P-type PERC cells, which are susceptible to Light-Induced Degradation (LID) of 1–3% in the first weeks of operation. N-type alternatives (TOPCon, HJT) available at comparable power levels show no LID, lower temperature coefficients (-0.29% to -0.30%/°C), and a higher long-term efficiency ceiling. - **Monofacial design with bifacial alternatives available** - The JS210MHC110 series is monofacial (non-bifacial). At the same power class, Premier Energies 144HC PERC Bifacial Dual Glass (560 Wp, 21.67%) is available and can generate an additional 5–15% energy yield from rear-side irradiance on reflective ground surfaces (gravel, sand, white membranes). ## About this series JS Solar JS210MHC110 photovoltaic panels are an advanced solution based on **210 mm silicon cells** that redefine the efficiency of modern installations. The use of **Half-Cut and Multi-Busbar (MBB)** technology allows for a significant reduction in resistance losses and better module performance in partial shading conditions. Thanks to smaller gaps between busbars, the current flows more efficiently, resulting in lower thermal loads and a longer lifespan for the components. This series effectively solves the problem of limited installation space by offering high power density per square meter. This is particularly important for large commercial projects and PV farms, where **lowering the LCOE energy cost** by reducing expenditures on support structures and cabling is key. JS Solar JS210MHC110 stands out from the competition with an excellent temperature coefficient, which guarantees stable yields even on hot days. It is intended for investors seeking **maximum reliability and a fast return on investment**, both in the industrial sector and for demanding residential installations. The robust frame construction ensures resistance to extreme weather phenomena, making this series one of the most cost-effective choices on the Polish market. ## Notable figures - Module efficiency of 21.0% is 0.8pp below average for \*\*database\*\* panels (median: 21.8%) - Power density of 210.5 W/m² is 7.6 W/m² below \*\*database\*\* median (218.1 W/m²) - needs more roof space - Temperature coefficient of -0.34%/°C is 0.04pp worse than \*\*database\*\* median (-0.30%/°C) - higher losses in summer heat - At 28.6 kg, this panel is 2.1 kg heavier than the \*\*database\*\* median (26.5 kg) - more demanding for installation crews - In the top 70% for efficiency among all N-type panels ## Questions ### What is the maximum power output of the JS Solar JS210MHC110 and does it have a positive power tolerance? The JS Solar JS210MHC110 reaches a peak power of 560 Wp with a tolerance of 0~+5 W, meaning every module leaving the factory meets or exceeds its rated output. This matters especially in large commercial and utility-scale PV projects, where cumulative deviations across hundreds of panels can significantly affect the total energy yield of the system. ### What practical benefit do Half-Cut cells and Multi-Busbar technology bring to the JS210MHC110? Half-cut cells split each cell in two, halving the operating current and cutting resistive losses. Multi-Busbar (MBB) technology uses multiple thin busbars to shorten the current path and improve resistance to microcracks. In practice this means better performance under partial shading from chimneys or antennas, lower operating temperatures, and longer service life for the module. ### What is the power and product warranty on JS Solar JS210MHC110 panels? The JS210MHC110 series carries a 25-year linear power warranty, guaranteeing a defined minimum output level throughout the system's operational life. A separate product warranty covering manufacturing defects is provided by the manufacturer. Before purchasing, confirm the exact terms with an authorized distributor in your country, as JS Solar is not currently listed among Bloomberg NEF Tier 1 bankable manufacturers. ### Are JS Solar JS210MHC110 panels suitable for large commercial installations and utility-scale PV farms? Yes, the JS210MHC110 series was designed with large-scale projects in mind. The 210 mm cells deliver high power density per square meter, reducing the number of modules, mounting structures, and cable runs required. This directly lowers the LCOE, the cost of generating each unit of energy over the full lifetime of the installation. ### Does the JS210MHC110 maintain good performance on hot summer days? Thanks to the favorable temperature coefficient inherent in 210 mm monocrystalline cells, the JS210MHC110 shows less power loss as cell temperature rises above 25°C compared to older technologies. The Half-Cut design further reduces module heating by cutting resistive losses, which is particularly relevant during extended summer operation at full irradiance. ### Is the JS Solar JS210MHC110 a bifacial panel? No, the JS210MHC110 is a monofacial panel and does not generate power from light reflected off the ground or mounting surface. If bifacial technology is a priority for your project — it can boost yield by several percentage points on high-albedo surfaces — you should consider bifacial series from JS Solar or alternative manufacturers that offer dual-glass or transparent-backsheet bifacial modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JS210MHC110-555W-fdb9c794e14f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.0 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.8 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.6 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.5 pp | | [JS Solar JS210MHC110-540](https://comparepv.com/panel/js-solar-js210mhc110-540) | 540 W | -10 W, -0.3 pp | | [JS Solar JS210MHC110-545](https://comparepv.com/panel/js-solar-js210mhc110-545) | 545 W | Very close match | | [JS Solar JS210MHC110-555](https://comparepv.com/panel/js-solar-js210mhc110-555) | 555 W | Very close match | | [JS Solar JS210MHC110-560](https://comparepv.com/panel/js-solar-js210mhc110-560) | 560 W | +10 W, +0.4 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +130 W, cooler, +4.2 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +125 W, cooler, +4.0 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +150 W, cooler, +4.0 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +145 W, cooler, +3.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +120 W, cooler, +3.8 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +120 W, cooler, +3.8 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +120 W, cooler, +3.8 pp | --- Source: https://comparepv.com/panel/js-solar-js210mhc110-550 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
