Middle of its segment, weak in heat
The Renesola RS6-550~560MBG-E3 series are modules designed for high energy production in areas where every square meter of roof or structure counts. 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.
Ranking
Signals from the data
Commercial, utility-scale, residential and hot-climate.
Hot climates, tight roof space and weight-limited structures.
Bottom 3% of the N-type 550-600 W segment, against a median of -0.290. Ranked 10,419th in the whole database.
Bottom 7% of the N-type 550-600 W segment, against a median of 22.45%. Ranked 7,542nd in the whole database.
Bottom 8% of the N-type 550-600 W segment, against a median of 52.3. Ranked 10,741st in the whole database.
N-type technology eliminates the LID (Light Induced Degradation) effect typical of PERC cells and offers a lower power temperature coefficient, translating into higher annual energy yield compared to older P-type modules, especially in hot climates.
The dual-glass bifacial design captures light reflected from the ground (albedo), which in ground-mount installations, flat roofs, and light-colored membranes can boost yield by several to over a dozen percent compared to a monofacial module of the same rated power.
Renesola offers a 30-year product power warranty, exceeding the standard 25 years offered by many peer competitors (e.g., Exiom, Fellow Energy, Premier Energies), improving LCOE calculation security for commercial projects and PV farms.
Efficiency of 21.29-21.68% is directly comparable to top competitors (Exiom 21.7%, Fellow Energy 21.7%, Premier Energies 21.67%), confirming the series doesn't lag technologically behind the leading bifacial N-type module makers.
Renesola is a tier-1 (bankable) manufacturer, operating since 2005, which facilitates project financing through banks and leasing institutions and increases confidence in long-term warranty fulfillment.
The product warranty is 12 years, while many premium-segment leaders (including some comparable bifacial N-type modules) now standardly offer 15 years against material and workmanship defects, which competitors could use as a selling point.
- At 21.7% efficiency, this panel is 0.8pp below the N-type 550-600W median of 22.4%
- Power density of 216.8 W/m² is 7.7 W/m² below N-type 550-600W median (224.5 W/m²) - needs more roof space
- At -0.35%/°C, loses 0.06pp more power per degree than N-type 550-600W median (-0.29%/°C)
- At 31.7 kg (2.2 kg above N-type 550-600W median of 29.5 kg), requires checking roof load capacity
- Ranked #7542 out of 14005 panels for efficiency in the database
