This means more roof area is needed to achieve the same installed capacity. - **Older technology generation** - Introduced in 2018, the series relies on cell architecture predating the commercial maturity of newer designs now used by leading tier-1 manufacturers, resulting in a lower power-to-area ratio compared to current modules in the same price class. ## About this series The Renesola 156M Split Cell series, with 300W-330W power output, is designed for stable operation in typical Polish rooftop conditions, where predictable energy yield is crucial, even with partial shading, dirt accumulation, and varying weather. The use of the **split cell (half-cut) architecture** minimizes internal losses and improves the module's performance under uneven sunlight, resulting in a more consistent energy production throughout the day. The modules utilize **monocrystalline** silicon cells, and the design focuses on **high resistance to microcracks** and long-term operational loads. This makes it an ideal choice for residential homes, small businesses, and the modernization of existing systems where dimensional compatibility and reliable performance are important. Another key advantage is **excellent performance in low light conditions**, allowing the modules to effectively utilize early morning and late afternoon sunlight. This is a cost-effective option for investors who want to minimize energy yield losses without paying a premium for high-end solutions. ## Notable figures - Module efficiency of 15.5% is 0.5pp below average for \*\*TOPCon 0-400W\*\* panels (median: 16.0%) - At 154.6 W/m², this panel generates 5.2 W/m² less per unit area than \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - Temperature coefficient of -0.35%/°C is 0.06pp worse than \*\*TOPCon 0-400W\*\* median (-0.29%/°C) - higher losses in summer heat - At 20.4 kg, this panel is 3.1 kg lighter than \*\*TOPCon 0-400W\*\* median (23.5 kg) - easier handling during installation - In the top 98% for efficiency among all TOPCon panels ## Questions ### Is the Renesola 156M Split Cell 300W-330W series still available for purchase? The Renesola 156M Split Cell 300W-330W series has been officially discontinued and is no longer in production. Limited stock may still be available through some distributors, but it should not be specified in new projects. For expansions or retrofits of existing systems, verify the module's exact dimensions carefully to select a dimensionally compatible replacement from Renesola's current lineup or another Tier 1 manufacturer. ### What advantage does TOPCon cell technology give the Renesola 156M Split Cell panels over PERC? TOPCon (Tunnel Oxide Passivated Contact) cells reduce recombination losses at the rear cell surface, resulting in higher conversion efficiency than standard PERC cells. In practical terms, this means greater energy yield from the same roof area and a more favorable temperature coefficient, so power losses on hot summer days are smaller compared to previous-generation technologies. ### How does the half-cut (split cell) architecture affect Renesola 156M performance under partial shading? Splitting each cell in half reduces the operating current in each section by half, lowering resistive losses and limiting the impact of shading on one part of the module to the rest of the array. On a typical Polish rooftop with chimneys, dormers, or neighboring structures, the half-cut design helps maintain more consistent energy production throughout the day. ### What warranty does the Renesola 156M Split Cell 300W-330W carry? The manufacturer offered a 30-year product warranty covering physical and material defects, plus a 30-year linear power output warranty. This extended protection period is standard for Tier 1 manufacturers and provides solid investment assurance. Since the series is discontinued, confirm the current warranty terms directly with an authorized Renesola distributor before purchasing remaining stock. ### Do Renesola 156M Split Cell panels perform well in low-light conditions — morning and evening? Yes. Monocrystalline TOPCon cells combined with half-cut architecture improve module behavior at low irradiance levels. The panels capture morning and late-afternoon production windows more effectively, which is particularly relevant in the Polish climate where diffuse and low-angle irradiance accounts for a significant portion of annual energy yield. ### What type of installation is the Renesola 156M Split Cell 300W-330W best suited for? The series is best suited for residential prosumer installations on pitched roofs and small commercial systems. The 156 mm cell format and 300-330 W power range make the modules convenient for retrofitting older systems where dimensional compatibility matters. The modules are monofacial (not bifacial), so they are optimized for roof-mounted installations or ground-mounted systems with single-side exposure. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/300w-330w-36p-2713a213bb21.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [SunLink LNSK-340M](https://comparepv.com/panel/sunlink-lnsk-340m) | 340 W | +40 W, +4.6 pp, -5 yr warranty | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | +30 W, +4.4 pp, -5 yr warranty | | [Canadian Solar CS3K-335MB-AG](https://comparepv.com/panel/canadian-solar-cs3k-335mb-ag) | 335 W | +35 W, heavier, +4.4 pp | | [SunLink LNSK-335M](https://comparepv.com/panel/sunlink-lnsk-335m) | 335 W | +35 W, +4.3 pp, -5 yr warranty | | [Canadian Solar CS3K-325P](https://comparepv.com/panel/canadian-solar-cs3k-325p) | 325 W | +25 W, +4.1 pp, -5 yr warranty | | [SunLink LNSK-330M](https://comparepv.com/panel/sunlink-lnsk-330m) | 330 W | +30 W, +4.0 pp, -5 yr warranty | | [Canadian Solar CS3K-320P](https://comparepv.com/panel/canadian-solar-cs3k-320p) | 320 W | +20 W, +3.8 pp, -5 yr warranty | | [Renesola YH310W-36P](https://comparepv.com/panel/renesola-yh310w-36p) | 310 W | +10 W, +0.5 pp | | [Renesola YH320W-36P](https://comparepv.com/panel/renesola-yh320w-36p) | 320 W | +20 W, +1.0 pp | | [Renesola YH330W-36P](https://comparepv.com/panel/renesola-yh330w-36p) | 330 W | +30 W, +1.6 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +175 W, +8.5 pp, +10 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +170 W, +8.2 pp, +10 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | +165 W, +8.0 pp, +10 yr warranty | | [Maxeon SPR-MAX6-440](https://comparepv.com/panel/maxeon-spr-max6-440) | 440 W | +140 W, +7.3 pp, +10 yr warranty | | [Maxeon SPR-MAX6-435](https://comparepv.com/panel/maxeon-spr-max6-435) | 435 W | +135 W, +7.0 pp, +10 yr warranty | | [Lina Energy LEPV 132 ULTRA PREMIUM BLACK 440Wp (LEPV 440)](https://comparepv.com/panel/lina-energy-lepv-132-ultra-premium-black-440wp-lepv-440) | 440 W | +140 W, cooler, +6.9 pp | --- Source: https://comparepv.com/panel/renesola-yh300w-36p Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
