This means limited access to new units and spare parts, along with harder-to-enforce warranty claims despite the formal 30-year coverage. - **Efficiency trails segment leader** - Efficiency of 18.47-19.44% falls below the comparable JA Solar Monocrystalline36 100W panel (21.29%) by 1.85-2.82 percentage points, though it still outperforms TPL Solar's TPL S-36 (15.67%). At equal power, this means a somewhat larger module footprint versus JA Solar. ## About this series The Renesola 210M Split Cell 95W-100W series is designed for small installations where predictable performance and resistance to real-world mounting conditions are crucial. The use of **split cell technology** helps minimize losses in partially shaded conditions and reduces the risk of yield reductions when panels are shaded by trees, antennas, or building elements. This solution is particularly appreciated in RVs, boats, vacation homes, and off-grid power systems. A key feature of this series is its emphasis on **durability in harsh environments** - the modules are designed to withstand moisture, salt, and dust, which increases their suitability in off-grid locations and on structures exposed to weather conditions. In addition, the manufacturer uses **anti-PID protection**, which helps maintain stable performance over a longer period. Another important quality control element is **double electroluminescence (EL) testing**, which helps detect microscopic cracks that are not visible to the naked eye. This is a proposal for those who need compact power but do not want to compromise on quality and reliability. ## Notable figures - 19.4% module efficiency - 3.5pp better than the \*\*TOPCon 0-400W\*\* median of 16.0% - At 194.4 W/m² power density, this panel generates 34.6 W/m² more per unit area than \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - Temperature coefficient of -0.34%/°C is 0.05pp worse than \*\*TOPCon 0-400W\*\* median (-0.29%/°C) - higher losses in summer heat - At 5.4 kg, this panel is 18.1 kg lighter than \*\*TOPCon 0-400W\*\* median (23.5 kg) - easier handling during installation - In the top 91% for efficiency among all TOPCon panels ## Questions ### Is the Renesola 210M Split Cell 95W–100W series still available for purchase? The Renesola 210M Split Cell 95W–100W series has been discontinued and is no longer part of the regular product lineup. If you need similar specs for off-grid, RV, or marine use, check with your distributor for remaining stock or look into a current Renesola equivalent that fits your application. ### How does split cell technology work in the Renesola 210M panels, and does it actually help with shading? Split cell technology divides each solar cell into two smaller halves, reducing internal resistance and limiting output losses under partial shading. If a railing, antenna, or structural element casts a shadow over part of the panel, a split cell module loses less power than a conventional full-cell design. This is a tangible advantage in mobile and small-scale installations where shading is hard to avoid. ### Are the Renesola 210M Split Cell 95–100 W panels suitable for RV or marine installations? Yes, the 210M Split Cell series was designed with exactly these applications in mind. Compact output up to 100 W, resistance to moisture and salt, and anti-PID protection make the modules well-suited for boats and RVs. Dual electroluminescence (EL) testing during production reduces the risk of hidden microcracks — important in environments with constant vibration from driving or sailing. ### What is TOPCon technology used in this series, and is it a better choice than PERC? TOPCon (Tunnel Oxide Passivated Contact) is a newer cell generation that typically achieves 1–2 percentage points higher conversion efficiency than standard PERC cells, meaning more energy from the same panel area. In the Renesola 210M Split Cell, this translates to better yield in space-constrained setups such as an RV roof or a small off-grid system. ### What warranty does the Renesola 210M Split Cell 95W–100W series carry? Renesola backs this series with a 30-year product warranty and a 30-year power output warranty. The power warranty guarantees that the panels will maintain a minimum performance level defined by Renesola for three decades. This is among the longer warranties available for compact modules, reflecting the manufacturer's stated confidence in the series durability. ### Are the Renesola 210M Split Cell panels rated for harsh environmental conditions — salt, moisture, and dust? Yes, the 210M Split Cell series was built for demanding environments. The modules have been tested for salt mist and humidity resistance, making them a practical choice for coastal installations, marine use, or dusty locations. Anti-PID protection further stabilizes electrical performance over time when the panels are exposed to variable operating conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/95-100w-770x668x30-1f5afebf0d7c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M150W](https://comparepv.com/panel/gamko-new-energy-gka182m150w) | 150 W | +50 W, heavier, +3.6 pp | | [Gamko New Energy GKA182M120W](https://comparepv.com/panel/gamko-new-energy-gka182m120w) | 120 W | +20 W, +3.6 pp | | [Gamko New Energy GKA182M135W](https://comparepv.com/panel/gamko-new-energy-gka182m135w) | 135 W | +35 W, +3.6 pp | | [Gamko New Energy GKA182M100W](https://comparepv.com/panel/gamko-new-energy-gka182m100w) | 100 W | +3.6 pp | | [Gamko New Energy GKA182M110W](https://comparepv.com/panel/gamko-new-energy-gka182m110w) | 110 W | +10 W, +3.6 pp | | [JA Solar NS-100MH-36](https://comparepv.com/panel/ja-solar-ns-100mh-36) | 100 W | Cooler, +1.8 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-100MH-36](https://comparepv.com/panel/polycrown-solar-tech-ns-100mh-36) | 100 W | Cooler, +1.8 pp, -5 yr warranty | | [Renesola YH120W-18M](https://comparepv.com/panel/renesola-yh120w-18m) | 120 W | +20 W, heavier | | [Easun Power YH100W-12M](https://comparepv.com/panel/easun-power-yh100w-12m) | 100 W | Hotter, lighter | | [Isola New Energy YH120W-18M](https://comparepv.com/panel/isola-new-energy-yh120w-18m) | 120 W | +20 W, heavier | | [Renesola YH95W-18M](https://comparepv.com/panel/renesola-yh95w-18m) | 95 W | -1.0 pp | | [Isola New Energy YH100W-12M](https://comparepv.com/panel/isola-new-energy-yh100w-12m) | 100 W | Hotter, lighter | | [Centro Energy CE-100M36](https://comparepv.com/panel/centro-energy-ce-100m36) | 100 W | Hotter, -5 yr warranty | | [Isola New Energy YH100W-18M](https://comparepv.com/panel/isola-new-energy-yh100w-18m) | 100 W | Very close match | | [Isola New Energy YH95W-18M](https://comparepv.com/panel/isola-new-energy-yh95w-18m) | 95 W | -1.0 pp | | [Resun Solar RSM080P](https://comparepv.com/panel/resun-solar-rsm080p) | 80 W | -20 W, hotter, -3.9 pp | --- Source: https://comparepv.com/panel/renesola-yh100w-18m Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
