This is particularly relevant in the Polish climate, where direct irradiance is limited for a significant portion of the year. - **Certified PID, salt mist, and ammonia resistance** - The series passed IEC 61215 and IEC 61730 qualification tests along with additional PID resistance, salt mist, and ammonia corrosion procedures. This mitigates laminate-ingress degradation in industrial and agricultural environments, as confirmed by ENF Solar Directory data for the JSS-60P line. - **Up to 17.2% efficiency — above peer comparables** - Peak module efficiency of 17.2% (280 Wp variant) exceeds Gintech GIN P6F-60 (17.0%) and TPL P-60 Series (17.1%), placing the series in the top quartile of its peer group and on par with Rarlon PV Tech Poly 60-cell (17.21%). - **25-year linear power warranty** - The manufacturer guarantees a minimum of 80.7% of rated power output over 25 years — meeting the full market standard for mid-range modules and aligning with typical warranty terms offered by larger competitors during the 2014–2021 period. ## Cons - **Series discontinued (end-of-life 2021)** - The 60 Series reached end-of-life in 2021, meaning no new modules have been commercially available for over four years. Expanding an existing installation with identical modules is impractical, and access to service support, certified replacement components, and up-to-date technical documentation is severely limited. - **Non-Tier-1, non-bankable manufacturer** - JS Solar does not appear on the BNEF Tier-1 bankable manufacturers list (confirmed as of Q1 2026). This creates material obstacles for securing project finance from banks for commercial-scale systems and raises due-diligence requirements from insurers and infrastructure funds. - **Efficiency well below current-generation standards** - Modern monocrystalline PERC, TOPCon, and HJT modules routinely achieve 20–22% efficiency. On a roof with a fixed mounting area, a new installation using current-generation panels would produce approximately 15–25% more energy than one based on the 60 Series, significantly worsening LCOE in space-constrained scenarios. ## About this series The JS Solar 60 Series of photovoltaic panels is a solution for investors who want to combine a compact module format with high predictability of performance in real-world conditions. The use of monocrystalline cells and a refined design minimize losses due to parameter mismatches, and also reduce the impact of partial shading - which, in practice, helps maintain more stable energy production on roofs with chimneys, skylights, or nearby trees. These modules are characterized by **good performance in low-light conditions**, making them suitable for the Polish climate, where efficiency in the morning and afternoon hours is important. For durability, **multiple electroluminescence tests**, **resistance to PID (Potential Induced Degradation)**, and **enhanced mechanical resistance to loads and environmental conditions**, including salt and ammonia, are crucial. This makes them a good choice for residential, small business, and commercial installations, where **certainty of yield and ease of integration with common components** are important. ## Notable figures - At 15.9% efficiency, this panel is 5.9pp below the \*\*database\*\* median of 21.8% - Power density of 159.8 W/m² is 58.3 W/m² below \*\*database\*\* median (218.1 W/m²) - needs more roof space - At -0.42%/°C, loses 0.12pp more power per degree than \*\*database\*\* median (-0.30%/°C) - At 19.3 kg, this panel is 7.2 kg lighter than \*\*database\*\* median (26.5 kg) - easier handling during installation - In the top 98% for efficiency among all N-type panels ## Questions ### Is the JS Solar 60 Series still available for purchase? The JS Solar 60 Series has been discontinued and is no longer offered as a new product. Limited stock may still be available through distributors' warehouses. If you need a comparable replacement with a similar compact format, consider newer JS Solar series or other currently produced entry-level monocrystalline modules. ### What warranty does the JS Solar 60 Series come with? JS Solar provides a 10-year product warranty covering materials and workmanship, plus a 25-year power output warranty. After 25 years the module is guaranteed to retain at least 80.2% of its rated power. This is a standard warranty scope for monocrystalline panels in the prosumer and light commercial segment. ### How does the JS Solar 60 Series perform under cloudy skies in a Central European climate? The monocrystalline cells used in the 60 Series deliver solid low-light performance, generating power efficiently under overcast skies and during morning or evening hours. In Poland's climate, where diffuse radiation is common, this translates into a higher annual energy yield compared to modules with weaker low-irradiance characteristics — one of the key advantages highlighted by the manufacturer. ### What is PID resistance, and is it present in the JS Solar 60 Series? PID (Potential Induced Degradation) is a form of accelerated aging triggered by high system voltage, causing a gradual drop in module power output. The JS Solar 60 Series is certified PID-resistant, minimizing this risk in standard residential and commercial PV systems and helping the module maintain consistent output throughout its 25-year power warranty period. ### Is the JS Solar 60 Series suitable for a roof with chimneys, dormers, or nearby trees? Yes. The 60 Series is engineered to minimize mismatch losses caused by partial shading from chimneys, dormers, or nearby trees. When part of the array is shaded, the string loses less power than older designs. For particularly challenging roof layouts, pairing the modules with power optimizers or microinverters will further improve overall system yield. ### What is the rated power of the JS Solar 60 Series, and what type of installations is it designed for? The JS Solar 60 Series offers modules rated up to 280 Wp. With compact dimensions of approximately 1,640 × 992 mm and a weight of around 18 kg, they fit well on residential roofs, small commercial buildings, and constrained roof areas. They are a practical choice wherever reliable energy production at a moderate BoS cost is the priority. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/a3dc3f9f626fb943b41fb56ded0c97ae-c8138dad3e9e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Canadian Solar CS3K-310P-AG](https://comparepv.com/panel/canadian-solar-cs3k-310p-ag) | 310 W | +50 W, cooler, +2.8 pp | | [Rarlon PV Tech RL310HP-120](https://comparepv.com/panel/rarlon-pv-tech-rl310hp-120) | 310 W | +50 W, cooler, +2.7 pp | | [Canadian Solar CS3K-310PB-AG](https://comparepv.com/panel/canadian-solar-cs3k-310pb-ag) | 310 W | +50 W, cooler, +2.5 pp | | [Canadian Solar CS3K-305P-AG](https://comparepv.com/panel/canadian-solar-cs3k-305p-ag) | 305 W | Cooler, +2.5 pp, +5 yr warranty | | [SunLink LNSK-310P](https://comparepv.com/panel/sunlink-lnsk-310p) | 310 W | +50 W, cooler, +2.4 pp | | [Rarlon PV Tech RL305HP-120](https://comparepv.com/panel/rarlon-pv-tech-rl305hp-120) | 305 W | +45 W, cooler, +2.4 pp | | [Waaree WS-295](https://comparepv.com/panel/waaree-ws-295) | 295 W | +35 W, cooler, +2.3 pp | | [Canadian Solar CS3K-305PB-AG](https://comparepv.com/panel/canadian-solar-cs3k-305pb-ag) | 305 W | Cooler, +2.2 pp, +5 yr warranty | | [JS Solar JS265P](https://comparepv.com/panel/js-solar-js265p) | 265 W | +0.3 pp | | [JS Solar JS270P](https://comparepv.com/panel/js-solar-js270p) | 270 W | +10 W, +0.6 pp | | [JS Solar JS275P](https://comparepv.com/panel/js-solar-js275p) | 275 W | +15 W, +0.9 pp | | [JS Solar JS280P](https://comparepv.com/panel/js-solar-js280p) | 280 W | +20 W, +1.3 pp | | [JS Solar JS305M](https://comparepv.com/panel/js-solar-js305m) | 305 W | +45 W, lighter, +2.8 pp | | [JS Solar JS310M](https://comparepv.com/panel/js-solar-js310m) | 310 W | +50 W, lighter, +3.2 pp | | [JS Solar JS315M](https://comparepv.com/panel/js-solar-js315m) | 315 W | +55 W, lighter, +3.5 pp | | [JS Solar JS320M](https://comparepv.com/panel/js-solar-js320m) | 320 W | +60 W, lighter, +3.8 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +6.7 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/js-solar-js260p Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
