Strong in heat, no clear weak spot
The Renesola 182M Half Cell 450W-465W series is designed for high energy production on the same roof or ground area, without compromising reliability. The use of half-cut cells helps to minimize internal losses and improves module performance when part of the panel is temporarily shaded - which, in practice, translates to more stable output in real-world conditions. It is also distinguished by MBB technology, which improves the collection of current from the cells and supports the even operation of the entire laminate over a long period. A key advantage is good performance in low-light conditions - the modules better utilize early mornings, evenings, and cloudy days. Furthermore, the series is designed for demanding environments thanks to weather resistance and a refined design. This makes it a suitable choice for residential and commercial installations, especially where predictable production and resistance to common roof-related problems are important.
Ranking
Signals from the data
Residential, commercial and shaded-installations.
Top 1% of the TOPCon 450-500 W segment, against a median of -0.290. Ranked 13th in the whole database.
Top 10% of the TOPCon 450-500 W segment, against a median of 225.2.
Top 12% of the TOPCon 450-500 W segment, against a median of 22.52%.
Efficiency at the top of the series range (up to 23.27%) clearly exceeds comparable 182M modules of similar 465W power - Jinko JS182MHC120 (21.48%) and Vikram SOMERA (21.51%) - meaning higher energy yield from the same roof area.
A full 30 years of both product and power output warranty is rarely seen in this segment - the market standard is 25/25 years - making this series attractive from a long-term ROI perspective.
N-type TOPCon cells in a bifacial configuration allow additional energy yield from reflected light on the rear side of the module, a meaningful advantage over older-generation monofacial PERC designs.
Combining multi-busbar (MBB) with half-cut cells reduces resistive losses and improves resilience to partial shading, resulting in more stable output under variable irradiance conditions typical of the Polish climate.
This series was produced from 2021 to 2024 and is no longer part of the manufacturer's current lineup. This limits availability of identical modules for expanding existing installations and may slow warranty claims requiring spare parts.
Renesola appeared on the BNEF Tier 1 list as recently as Q1/Q2 2026, but was absent from the Q3 2026 ranking, indicating it no longer met some of BloombergNEF's financial or documentation criteria - raising questions about the brand's current bankability.
Despite a strong 23.27% rating, the series trails Luxor Solar's ECO LINE TOPCON Glass-Glass Bifacial (23.6% at the same 465W max power), meaning it is not the absolute segment leader in power density.
- 23.3% module efficiency - 0.8pp better than the TOPCon 450-500W median of 22.5%
- Power density of 232.7 W/m² packs 7.5 W/m² more into the same footprint vs TOPCon 450-500W median (225.2 W/m²)
- At -0.24%/°C (vs median -0.29%/°C), loses ~2% less power in hot conditions
- In the top 9% for efficiency among all TOPCon panels
