This translates into reliable product warranty coverage and access to technical support years after purchase. - **PERC + half-cut + multi busbar** - The combination of monocrystalline PERC cells with a half-cut architecture reduces resistive losses by approximately 50% compared to full cells, while multi busbar (MBB) technology lowers the risk of microcracks and hot-spots. The result is improved tolerance to partial shading and higher reliability over years of operation. - **18.75-19.36% efficiency vs. Solaria** - The series reaches up to 19.36% module efficiency, outperforming peer comparable Solaria PowerXT 54L (15.87%) by 3.49 percentage points. For a typical 10-module rooftop installation on roughly 16 m², this gap can translate to approximately 10-12% higher annual energy yield versus Solaria modules. - **25-year linear power warranty** - The manufacturer provides a 25-year linear performance warranty - matching the current Tier-1 market standard. A linear (non-stepped) degradation guarantee simplifies long-term LCOE forecasting and is well-regarded by project finance lenders. ## Cons - **Discontinued series (end of production 2020)** - The 60+ Series went out of production around 2020. New units are unavailable through regular distribution channels, and the availability of matching replacement modules for system expansion, spare parts, and technical documentation required by insurers and project finance banks is severely limited - a material risk for assets with a 20-25 year investment horizon. - **Efficiency well below Solar-Fabrik S5 Halfcut** - Peer comparable Solar-Fabrik Mono S5 Halfcut achieves 21.69% module efficiency at a similar power output (315 Wp), outperforming the Jinko 60+ Series by approximately 2.33-2.94 percentage points. On space-constrained rooftops this efficiency gap meaningfully limits the maximum installable capacity. - **Product warranty of only 10 years** - Current Tier-1 modules (JA Solar, Trina, LONGi) routinely offer 12-15 year product warranties. The 10-year product warranty of the 60+ Series falls below current market expectations - a concern compounded by the series being discontinued, which increases the practical difficulty of filing warranty claims. ## About this series The Jinko Solar 60+ Series monocrystalline photovoltaic modules are designed to maximize energy yield from a typical roof format, without compromising on durability. The use of monocrystalline cells (often with PERC technology) and internal loss-reducing solutions ensures that the modules perform well not only in ideal sunlight, but also in less ideal conditions and with varying temperatures. The **half-cut cells** enhance tolerance to partial shading and help minimize hot-spot losses, while the **multi-busbar technology** increases connection reliability and stability over time. Furthermore, the modules are designed with a focus on **PID resistance** and **resistance to harsh environmental conditions** (e.g., coastal or agricultural areas), which realistically reduces the risk of performance degradation over the long term. This makes them an ideal choice for residential and commercial installations, where consistent yield, reliability, and easy integration with popular mounting systems are key. ## Notable figures - At 19.4% efficiency, this panel is on par with typical \*\*PERC 0-400W\*\* modules - Power density of 193.6 W/m² matches the \*\*PERC 0-400W\*\* median - -0.42%/°C temperature coefficient - 0.06pp worse than \*\*PERC 0-400W\*\* median (-0.36%/°C), expect higher hot weather losses - Weight of 18.0 kg (2.5 kg below \*\*PERC 0-400W\*\* median of 20.5 kg) allows easier transport and roof mounting - #12863 for efficiency, #13920 for temperature performance out of 14129 panels ## Questions ### Is the Jinko Solar 60+ Series still available for purchase? The Jinko Solar 60+ Series Monocrystalline Photovoltaic Modules has been discontinued and is no longer offered as new stock by authorized distributors. Models such as the JKM315M-60 may occasionally appear on the secondary market or in residual distributor inventory. If you need new Jinko Solar panels, consider current lineups such as the Tiger Neo or Tiger Pro series. ### What warranty does the Jinko Solar 60+ Series come with? Jinko Solar provides a 10-year product warranty covering material and workmanship defects, and a 25-year linear power warranty guaranteeing output stays above specified thresholds. Because the series is discontinued, warranty claims may require contacting Jinko Solar's service center or an authorized partner directly. Keep your purchase documents and product registration on file to simplify any future claims. ### What are half-cut cells and why do they matter in the Jinko Solar 60+ Series? Half-cut cell technology splits each silicon cell in half, reducing resistive losses and improving tolerance to partial shading. In practice, if a chimney or antenna shades part of the panel, the unshaded half continues generating power efficiently. In the 60+ Series, half-cut PERC cells combined with multi busbar interconnection reduce hotspot risk and improve long-term reliability of electrical connections. ### How do Jinko Solar 60+ Series panels perform in overcast or low-light conditions? The modules use monocrystalline PERC cells, which outperform polycrystalline cells under diffuse or low-intensity light. The PERC rear reflective layer captures photons that would otherwise pass through the cell, delivering measurable gains on cloudy days typical of Central European climates. While output is naturally lower than in full sun, the panels continue generating usable energy in overcast conditions. ### What is the peak power output of the Jinko Solar 60+ Series and what installations is it suited for? The top model in the series is rated at 315 Wp. This output level and the standard 60-cell form factor make it a natural fit for residential rooftop systems and small commercial installations using conventional racking with 1000-1200 mm rail spacing. The panels are compatible with most standard mounting systems and are manageable in terms of weight and dimensions for rooftop transport and installation. ### Is the Jinko Solar 60+ Series resistant to harsh environments such as coastal or agricultural sites? Yes, the modules were engineered with resistance to salt mist corrosion and ammonia exposure, making them suitable for coastal locations and farmland installations. Jinko Solar also built in PID resistance, which protects against accelerated cell degradation in high-humidity environments. Despite the series being discontinued, correctly installed modules should maintain their rated performance over the long term under normal operating conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/655b6673cbb193c99f520d6c131c16a5-e8316ea883e2.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Cooler, lighter, +4.0 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +4.0 pp | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | Cooler, +3.9 pp, +5 yr warranty | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +3.8 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.8 pp | | [Heckert Solar ZEUS 3.2 285WP FullBlack](https://comparepv.com/panel/heckert-solar-zeus-3-2-285wp-fullblack) | 285 W | Cooler, +3.8 pp, +5 yr warranty | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | Lighter, +3.6 pp, +5 yr warranty | | [Gamko New Energy GKA182M270W](https://comparepv.com/panel/gamko-new-energy-gka182m270w) | 270 W | Lighter, +3.6 pp, +5 yr warranty | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | Lighter, +3.6 pp, +5 yr warranty | | [Jinko Solar JS305M](https://comparepv.com/panel/jinko-solar-js305m) | 305 W | -10 W, -0.6 pp | | [Jinko Solar JS310M](https://comparepv.com/panel/jinko-solar-js310m) | 310 W | -0.3 pp | | [Jinko Solar JS330M](https://comparepv.com/panel/jinko-solar-js330m) | 330 W | +15 W, cooler, +0.9 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +3.2 pp, +15 yr warranty | | [Lina Energy LEPV 400](https://comparepv.com/panel/lina-energy-lepv-400) | 400 W | +85 W, cooler, +2.9 pp | | [Phono Solar NS-360MH-60](https://comparepv.com/panel/phono-solar-ns-360mh-60) | 360 W | +45 W, cooler, +2.8 pp | | [PolyCrown Solar Tech NS-360MH-60](https://comparepv.com/panel/polycrown-solar-tech-ns-360mh-60) | 360 W | +45 W, cooler, +2.8 pp | --- Source: https://comparepv.com/panel/jinko-solar-js315m Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
