**HJT half-cut G12 cells** - Heterojunction (HJT) half-cut G12 cells deliver a very low power temperature coefficient of -0.24%/°C and stable performance under elevated module temperatures and partial shading, translating into higher yield in hot climates compared to conventional PERC cells. - **Bifacial technology with 86%±5% bifaciality** - The modules capture irradiance from both sides, and under suitable mounting conditions (height, ground albedo) can add 10-30% extra energy without increasing installation footprint, lowering project LCOE. - **30-year linear power warranty** - The manufacturer states an annual power degradation of just 0.3%/year over a 30-year power warranty - longer than the standard 25 years offered by most PERC/TOPCon manufacturers on the market. - **Manufactured at a gigawatt-scale HJT facility** - Modules are produced at the Dhirubhai Ambani Green Energy Giga Complex in Jamnagar, India, with BIS certification, providing large-scale quality control and a local supply chain independent of typical export constraints from China. - **Dual-glass construction and IP68 rating** - Double-glass build combined with an IP68-rated junction box improves resistance to moisture, PID and microcracks, supporting the claimed long-term durability for commercial and industrial installations. ## Cons - **Product warranty shorter than top premium peers** - The 15-year product warranty is a standard market baseline, but some premium HJT/TOPCon manufacturers (e.g., LONGi, Trina Vertex) already offer 20-25-year product warranties - RNE Pro-L does not stand out on this metric despite being positioned as a flagship series. - **Efficiency slightly below peer comparables** - Maximum efficiency of 23.1% at 720 Wp is marginally lower than competing modules from DMEGC (DMxxxG12T-B66HSW) and GCL (GCL-NH12/66GDF), which reach 23.2% at the same power class - a small but measurable gap. - **Limited market track record** - The series launched in 2024 (REI Expo), so long-term real-world degradation data is not yet available compared to established Tier-1 manufacturers with a longer history in HJT technology. ## About this series The RNE Pro-L series is Reliance New Energy's flagship photovoltaic module line, engineered for installations where maximizing energy yield from limited roof or ground space is the priority. These panels use **half-cut G12 heterojunction (HJT) cells**, delivering exceptionally stable performance even under elevated temperatures and partial shading conditions. Thanks to **bifacial** technology, the modules capture sunlight from both sides, boosting energy harvest without increasing the installation footprint, which directly lowers project LCOE. The series stands out with its **industry-leading power temperature coefficient** and minimal annual degradation, allowing it to maintain high productivity throughout the entire lifecycle of the installation. The HJT cell construction also delivers **outstanding resistance to degradation**, translating into reliable, predictable output backed by a long-term power warranty. RNE Pro-L is built for investors in commercial and industrial projects, as well as larger residential systems, who expect a strong return on investment with reduced operational risk. It's a panel for those who prioritize durability, stable energy production, and premium-grade modern silicon technology. ## Notable figures - Efficiency of 22.3% matches the \*\*HJT 650-700W\*\* median - Power density of 223.2 W/m² matches the \*\*HJT 650-700W\*\* median - Temperature coefficient of -0.24%/°C matches the \*\*HJT 650-700W\*\* median - Bifaciality factor of 86% can add 4-13% extra yield with reflective mounting surface - In the top 36% for efficiency among all HJT panels ## Questions ### How does the HJT cell technology in RNE Pro-L differ from classic PERC cells? HJT (heterojunction) cells combine crystalline silicon with a thin amorphous silicon layer, reducing energy losses at high temperatures and limiting long-term degradation. Unlike PERC, RNE Pro-L panels retain higher efficiency in summer heat and have a lower power temperature coefficient, producing more energy in hot climates or on poorly ventilated roofs. ### Does bifacial technology in RNE Pro-L actually increase energy yield? Yes, RNE Pro-L bifacial modules capture light on both the front and rear side, generating additional energy from light reflected off the roof, ground, or bright surfaces beneath the array. This delivers higher output from the same installed area without adding panels, lowering the LCOE per watt of installed capacity. ### What warranty comes with RNE Pro-L panels and what does it cover? The RNE Pro-L series includes a 15-year product warranty against material and workmanship defects, plus a 30-year linear power output warranty. Thanks to low annual degradation, the panels maintain high efficiency throughout their service life, making them a low-risk choice for long-payback investments. ### Are 720 Wp RNE Pro-L panels suitable for commercial and industrial installations? Yes, the high unit power of 720 Wp combined with HJT half-cut G12 cells makes RNE Pro-L well suited to solar farms, industrial rooftops, and larger residential systems. Fewer panels are needed to reach a target capacity, cutting installation, wiring, and mounting structure costs. ### How well does RNE Pro-L handle partial shading, such as from chimneys or trees? The half-cut cell design splits cells into smaller segments, limiting power loss across the whole panel when only part of it is shaded. Combined with HJT technology, which is less prone to hot spots, RNE Pro-L maintains more stable energy production than conventional modules under partial shading. ### How does low temperature affect the performance of RNE Pro-L panels? RNE Pro-L panels use HJT cells with one of the lowest power temperature coefficients on the market. This means that in cold weather, where crystalline silicon operates more efficiently, these modules generate relatively more energy relative to their rated power than standard PERC or TOPCon panels. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/reliance-690w-720w-bifacial-hjt-solar-panel-rne-pro-l-series-f6ad1dbef660.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -45 W, lighter, +2.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Hotter, lighter, +2.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Hotter, lighter, +2.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -50 W, lighter, +2.7 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Hotter, lighter, +2.7 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Hotter, lighter, +2.6 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -25 W, lighter, +2.5 pp | | [Reliance New Energy RNE690AA-66-BGG](https://comparepv.com/panel/reliance-new-energy-rne690aa-66-bgg) | 690 W | Very close match | | [Reliance New Energy RNE700AA-66-BGG](https://comparepv.com/panel/reliance-new-energy-rne700aa-66-bgg) | 700 W | Very close match | | [Reliance New Energy RNE705AA-66-BGG](https://comparepv.com/panel/reliance-new-energy-rne705aa-66-bgg) | 705 W | +10 W, +0.3 pp | | [Reliance New Energy RNE710AA-66-BGG](https://comparepv.com/panel/reliance-new-energy-rne710aa-66-bgg) | 710 W | +15 W, +0.5 pp | | [Reliance New Energy RNE715AA-66-BGG](https://comparepv.com/panel/reliance-new-energy-rne715aa-66-bgg) | 715 W | +20 W, +0.7 pp | | [Reliance New Energy RNE720AA-66-BGG](https://comparepv.com/panel/reliance-new-energy-rne720aa-66-bgg) | 720 W | +25 W, +0.8 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +110 W, hotter, +2.8 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +105 W, hotter, +2.6 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +100 W, hotter, +2.5 pp | --- Source: https://comparepv.com/panel/reliance-new-energy-rne695aa-66-bgg Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
