The use of **bifacial construction with double glass** allows for better utilization of reflected light from the ground, which improves yields in ground-mounted, flat-roof, and membrane/gravel systems. Thanks to **monocrystalline cells** and a refined connection architecture, the module operates reliably in varying conditions, and **low temperature losses** support performance on hot days. In practice, it solves typical investor problems: limited mounting area, the desire to maximize self-consumption, and the need for predictable performance over many years. An additional advantage is **a long linear warranty on output**, which improves the security of calculations in commercial projects. This is a sensible choice for companies, PV farms, and demanding prosumer installations, where competition often offers less durable construction or shorter parameter guarantees. ## Notable figures - Efficiency of 21.3% is 1.2pp below the \*\*N-type 550-600W\*\* median (22.4%) - Power density of 212.9 W/m² is 11.6 W/m² below \*\*N-type 550-600W\*\* median (224.5 W/m²) - needs more roof space - -0.35%/°C temperature coefficient - 0.06pp worse than \*\*N-type 550-600W\*\* median (-0.29%/°C), expect higher hot weather losses - At 31.7 kg (2.2 kg above \*\*N-type 550-600W\*\* median of 29.5 kg), requires checking roof load capacity - #8708 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### What is the warranty on the Renesola RS6-550~560MBG-E3 panels? The RS6-550~560MBG-E3 series comes with a 12-year product warranty and a 30-year linear power output warranty. The linear warranty guarantees a minimum performance level each year without steep early drops, making long-term ROI calculations more predictable — a key advantage for commercial projects and utility-scale PV farms. ### Are the Renesola RS6-550~560MBG-E3 modules suitable for ground-mount and flat-roof installations? Yes, the RS6-550~560MBG-E3 series is particularly well-suited for ground-mount systems and flat rooftops. The bifacial dual-glass construction harvests reflected irradiance from bright surfaces such as gravel, white TPO/PVC membranes, or concrete, meaningfully boosting energy yield compared to a monofacial module under the same conditions. ### What does bifacial mean in the RS6-560MBG-E3 series and what does it mean in practice? Bifacial means the module generates power from both the front and rear sides. In the RS6-550~560MBG-E3, the rear glass transmits reflected irradiance back to the cell surface, producing additional output known as bifacial gain. On ground-mount systems with high-albedo surfaces or flat roofs with light-colored membranes, real-world output can noticeably exceed the rated 560 Wp at STC. ### What cell technology does the Renesola RS6-550~560MBG-E3 use and how does it compare to P-type panels? The RS6-550~560MBG-E3 uses N-type monocrystalline cells. Unlike P-type PERC, N-type silicon is significantly less prone to LID (Light Induced Degradation) and offers a lower temperature coefficient of Pmax. This translates to reduced power loss on hot days and more stable output across the full 30-year warranty period. ### How does high temperature affect the Renesola RS6-560MBG-E3 performance in summer? Thanks to N-type cell technology, the RS6-550~560MBG-E3 series features a low temperature coefficient of Pmax, meaning it loses less power as module operating temperature rises. The dual-glass construction also helps dissipate heat more evenly. Compared to older P-type modules, the output difference on hot summer days can be measurable, making this series a strong choice for high-irradiance locations across Central and Southern Europe. ### What is the rated power and efficiency of the Renesola RS6-550~560MBG-E3, and how much roof space do the panels need? The series covers 550 to 560 Wp (STC), with the top variant RS6-560MBG-E3 rated at 560 Wp. At approximately 2278×1134 mm with 144 half-cut N-type monocrystalline cells, the module achieves over 21% efficiency — competitive for installations where available roof or ground area is a limiting factor, whether on pitched roofs or in commercial systems. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/rs6-550-560mbg-182-144-bifacial-module-with-dual-glass-1-3bb930cfaa6f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.2 pp | | [Renesola RS6-555M-E3](https://comparepv.com/panel/renesola-rs6-555m-e3) | 555 W | Lighter, -5 yr warranty | | [Renesola RS6-560M-E3](https://comparepv.com/panel/renesola-rs6-560m-e3) | 560 W | Lighter, +0.4 pp, -5 yr warranty | | [Renesola RS6-570N-E3](https://comparepv.com/panel/renesola-rs6-570n-e3) | 570 W | Cooler, lighter, +0.8 pp | | [Renesola RS6-575N-E3](https://comparepv.com/panel/renesola-rs6-575n-e3) | 575 W | Cooler, lighter, +1.0 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/renesola-rs6-550mbg-e3 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
