In practice, they stand out due to their **positive power tolerance**, which makes the actual performance of the system more predictable even during the component selection phase. The design, based on a half-cut cell arrangement, improves performance under partial shading and reduces connection losses, which is particularly important on roofs with chimneys, skylights, or varying levels of sunlight exposure. Another advantage is the **high efficiency** of these modules in this power range - requiring fewer panels to achieve the desired output and simplifying installation. You will also appreciate the **stable performance in hot weather** and the **IP68 weatherproof enclosure**, which is better suited to harsh weather conditions. This makes it a good choice for installers looking for consistent parameters and a reasonable balance between power, reliability, and installation cost. ## Notable figures - Efficiency of 21.5% is 1.0pp below the \*\*N-type 550-600W\*\* median (22.4%) - At 214.8 W/m², this panel generates 9.7 W/m² less per unit area than \*\*N-type 550-600W\*\* median (224.5 W/m²) - Temperature coefficient of -0.35%/°C is 0.06pp worse than \*\*N-type 550-600W\*\* median (-0.29%/°C) - higher losses in summer heat - At 27.0 kg, this panel is 2.5 kg lighter than \*\*N-type 550-600W\*\* median (29.5 kg) - easier handling during installation - In the top 58% for efficiency among all N-type panels ## Questions ### What warranty does the Renesola RS6-550~560M-E3 series come with? The RS6-550~560M-E3 series comes with a 12-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty guaranteeing the module maintains a specified efficiency level over its lifetime. These are standard terms for Tier 1 manufacturers, a category Renesola belongs to. ### How does N-type cell technology in the Renesola RS6-550~560M-E3 compare to standard PERC panels? N-type cells have a lower degradation rate than conventional P-type PERC cells, meaning less power loss over the module's lifetime. They also respond better to diffuse light and maintain higher efficiency at elevated temperatures. In practice, this delivers a higher annual energy yield from the same roof area compared to an equivalent PERC module. ### Will the Renesola RS6-550~560M-E3 panels perform well on a roof with chimneys or dormers? Yes. The half-cut cell design splits each cell in two, so shading one section of the panel does not shut down the entire module. Partial shading losses are significantly lower than in standard full-cell panels, which matters most on roofs with chimneys, dormers, or antennas. The RS6-550~560M-E3 is a solid choice wherever partial shading is unavoidable. ### How many Renesola RS6-560M-E3 panels do I need for a 10 kWp system? At a peak power output of 560 W per module, you need approximately 18 panels for a 10 kWp system (18 × 560 W = 10,080 W). With module efficiency reaching 21.7%, each panel covers roughly 2.58 m², so an 18-panel array requires about 46 m² of roof space. Fewer modules also mean a simpler, faster installation. ### Is the junction box on the Renesola RS6-550~560M-E3 weatherproof enough for harsh climates? Yes, the junction box is rated IP68, providing full protection against dust ingress and water submersion. The panel handles heavy rain, snow, frost, and moisture condensation without issue. IP68 exceeds the industry-standard minimum of IP67, which translates to longer service life for the electrical connections in real-world outdoor conditions. ### Can the Renesola RS6-550~560M-E3 series be used for both rooftop and ground-mounted installations? Yes, the RS6-550~560M-E3 modules are designed for both applications. At 2278 × 1134 × 30 mm and approximately 27 kg, they are compatible with standard rooftop racking and ground-mount structures. The positive power tolerance and consistent output parameters make them especially practical for larger ground-mounted PV systems where accurate BoS sizing matters. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/rs6-550-560m-182-144-mono-facial-module-1-b56cdb541dee.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | -50 W, cooler, +3.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.1 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, +2.9 pp, +5 yr warranty | | [Renesola RS6-550M-E3](https://comparepv.com/panel/renesola-rs6-550m-e3) | 550 W | Very close match | | [Renesola RS6-560M-E3](https://comparepv.com/panel/renesola-rs6-560m-e3) | 560 W | Very close match | | [Renesola RS6-570N-E3](https://comparepv.com/panel/renesola-rs6-570n-e3) | 570 W | Cooler, +0.6 pp, +5 yr warranty | | [Renesola RS6-575N-E3](https://comparepv.com/panel/renesola-rs6-575n-e3) | 575 W | Cooler, +0.8 pp, +5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +80 W, cooler, +3.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +75 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/renesola-rs6-555m-e3 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
