Light for its output, no clear weak spot
The Renesola RS6-570~595N-E3 series are monofacial modules based on N-type cells in TOPCon technology, designed for high energy production under real-world operating conditions. The use of modern cell architecture helps minimize typical power losses, which translates into more stable yields over the long term - especially in installations operating in varying temperatures and with intermittent shading.
Compared to many competing solutions, it stands out due to extended linear warranty and a focus on long-term parameter predictability, which is important for calculating investment returns. The module's design also supports high resistance to environmental conditions, making it suitable for installations exposed to moisture, dust, and heavy use.
It is a good choice for companies and investors implementing installations on industrial rooftops, in agricultural settings, and in ground-mounted projects, where maximizing production from limited space and ensuring parameter stability over the long term are key.
Ranking
Signals from the data
Commercial, utility-scale, shaded-installations and hot-climate.
Top 21% of the N-type 550-600 W segment, against a median of 52.3.
The RS6 series achieves 22.07-23.03% efficiency, matching the best-in-class peers (Solarspace Lumina II at 23.03%, Heliene 144HC M10 at 23.02%) and clearly outperforming Sunova TS-BW78 (21.3%).
N-type cells offer lower LID/LeTID degradation and a favorable power temperature coefficient (-0.29%/°C), translating into higher real-world energy yield, especially in summer and high-temperature operating conditions.
The manufacturer guarantees a minimum of 87.4% of rated power after 30 years of operation, a significantly longer standard than the typical 25-year warranties offered by older PERC modules from some competitors.
Six power variants (570-595 Wp) in a 2278x1134 mm footprint help maximize energy production per unit of roof area - valuable for industrial and agricultural installations.
Renesola is a manufacturer with over 20 years in the renewable energy market, repeatedly listed on the BNEF Tier 1 list (including Q1 and Q2 2026), confirming its position as a recognized module supplier.
After appearing on BNEF Tier 1 lists in Q1 and Q2 2026, Renesola was absent from the Q3 2026 list - BloombergNEF excludes manufacturers showing signs of financial default. This may raise bankability concerns for projects financed around this series.
The series is monofacial only, while a direct competitor at the same peak power (Heliene 144HC M10 NTYP SL, 595 Wp) offers a bifacial variant, providing potential additional rear-side yield in ground-mount installations or on high-albedo surfaces.
- Efficiency of 22.4% matches the N-type 550-600W median
- Power density of 224.5 W/m² matches the N-type 550-600W median
- Temperature coefficient of -0.29%/°C matches the N-type 550-600W median
- Weight of 27.0 kg (2.5 kg below N-type 550-600W median of 29.5 kg) allows easier transport and roof mounting
- #4620 for efficiency, #2165 for temperature performance out of 14005 panels
