Middle of its segment, heavy for its output
The Renesola RS5-515~535NBG-E2 series is designed for installations where high energy yield on a limited area and stable performance over many years are crucial. These are bifacial modules that can also utilize reflected light from the ground, which significantly increases production compared to traditional monofacial panels, especially on bright roofs, ground-mounted structures, and PV farms.
The use of N-type cells in TOPCon technology results in better performance stability and more reliable operation in challenging conditions. In practice, this means more energy in the morning, evening, and on cloudy days, which is important in the Polish climate. Furthermore, the glass-glass design supports long-term durability, while solutions such as multi-busbar and half-cut cells improve efficiency and reduce losses under partial shading.
This is a good choice for premium prosumers, businesses, and commercial projects where profitability depends on maximizing energy yield, rather than compromising on performance.
Ranking
Signals from the data
Residential, commercial and shaded-installations.
Weight-limited structures.
Bottom 6% of the N-type 500-550 W segment, against a median of 50.0. Ranked 11,003rd in the whole database.
N-type TOPCon technology delivers lower LID/LeTID degradation and better high-temperature performance than legacy PERC cells, translating into higher annual energy yield, especially during periods of lower irradiance.
The modules capture light reflected from the ground surface, providing an additional yield gain over standard monofacial panels - particularly beneficial on light-colored roofs, ground-mount structures, and utility-scale PV farms.
ReneSola has maintained BNEF Tier 1 status for 11 consecutive years (confirmed again in Q1 2026), which streamlines project financing and is a key bankability criterion for institutional investors.
A 30-year power warranty extends beyond the market-standard 25 years offered by many tier-1 manufacturers, providing greater long-term energy production certainty and stronger project financial modeling.
The series' top-end efficiency (22.53%) matches the best comparable 535 Wp modules (e.g. Resun Solar RS8H-M-DG/BD) and clearly outperforms the competing Hanersun Hitouch 5 HN18-72H at the same maximum power, which reaches only 20.71%.
The double-glass (glass-glass) build, which supports durability and bifacial performance, typically adds weight versus glass-backsheet variants - a factor to account for when sizing mounting structures and roof load calculations in retrofit projects.
- At 22.5% efficiency, this panel is on par with typical N-type 500-550W modules
- At 225.3 W/m² power density, roof space requirements are typical for N-type 500-550W panels
- At -0.29%/°C, hot weather performance is typical for N-type 500-550W panels
- At 30.5 kg, this panel is 4.3 kg heavier than the N-type 500-550W median (26.2 kg) - more demanding for installation crews
- #3982 for efficiency, #2165 for temperature performance out of 14005 panels

Measured curves published by Renesola in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 535 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
Model: bifaciality × albedo × 0.6 view factor. A first-order estimate, not a yield simulation.
