Strong in heat, no clear weak spot
LG NeON R Prime are premium-class panels that redefine efficiency standards through the use of innovative N-type cell technology in Back-Contact architecture. The absence of busbars on the front of the module not only increases light absorption but also eliminates the risk of micro-cracks in critical points. This solution is dedicated to the most demanding investors, for whom maximum efficiency from a limited roof area while maintaining the highest aesthetics is key. Thanks to their unique structure, these panels perform excellently in challenging lighting conditions and at high temperatures, which translates into stable and high energy yields throughout the year. What sets the Prime series apart from the competition is its exceptional All-Black aesthetics combined with unprecedented mechanical durability. The use of a reinforced frame allows for safe installation in locations exposed to heavy snow and wind loads. By choosing these modules, the user invests in long-term energy security and reliability, confirmed by some of the best warranty terms on the market. It is an ideal choice for modern residential buildings where the photovoltaic system is intended to be not only a source of savings but also an element that increases the property's prestige.
Ranking
Signals from the data
Residential, hot-climate and BIPV.
Top 11% of the N-type 350-400 W segment, against a median of -0.320.
The absence of front-side busbars and electrodes (Back-Contact design) increases the active cell surface and eliminates the risk of micro-cracks at critical soldering points. N-type cells contain almost no boron, resulting in minimal LID (Light Induced Degradation) right after installation.
Efficiency up to 21.5% (LG390Q1K-A6 variant) places the series at the top of the segment, above JA Solar JAM60S21 (21.0%) and comparable to Meyer Burger Glass (21.2%) and Phono Solar Twinplus (21.3%), at the same 390 Wp max power.
LG provides 25 years of coverage on both product and power output, with linear degradation of about 0.3% per year after year one - guaranteeing roughly 90.8% of nominal power after 25 years. Full dual-scope coverage is rarely offered together even among Tier-1 manufacturers.
The reinforced frame construction allows safe installation in areas with elevated snow and wind loads, while the uniform All-Black look with no visible front busbars makes the panel a visually attractive choice for residential buildings.
The Back-Contact architecture combined with N-type cell technology limits performance drop at high module operating temperatures, delivering more stable energy yields during summer months compared to conventional PERC cells.
LG exited the solar panel business in 2022, meaning no new production and limited availability of warranty service and replacement parts (e.g., module swaps under claims) going forward, despite the formally active 25-year warranty.
Unlike some newer premium series on the market, LG NeON R Prime does not offer a bifacial version, limiting potential additional energy yield from ground albedo in ground-mounted or flat-roof installations.
- 20.7% module efficiency - 1.2pp better than the N-type 0-400W median of 19.5%
- At 206.8 W/m² power density, this panel generates 11.9 W/m² more per unit area than N-type 0-400W median (194.9 W/m²)
- At -0.29%/°C (vs median -0.32%/°C), loses ~1% less power in hot conditions
- 18.5 kg weight - 3.5 kg lighter than N-type 0-400W median (22.0 kg), reducing installation effort
- In the top 77% for efficiency among all N-type panels
