The panel uses **P-type PERC half-cut cells**, which reduce power losses from microcracks and partial shading while improving reliability under demanding operating conditions. A defining feature of the series is its **bifacial design**, capturing additional energy reflected from the ground surface and meaningfully boosting system efficiency without increasing the installation footprint. The use of **multi busbar (MBB) technology** combined with advanced soldering minimizes LID and LeTID degradation, extending the module's effective service life. A construction built on high-transmission tempered glass and a **corrosion-resistant, anodized frame** allows the panel to withstand salt mist and ammonia exposure, making it a strong choice for coastal and agricultural installations. A sealed IP68 junction box further protects the electrical components. ELAN PRIDE is aimed at investors seeking a balance between high energy performance and long-term durability, standing apart from monofacial competitors through its dual-side light capture and robust mechanical protection. ## Notable figures - Efficiency of 20.4% is 1.0pp below the \*\*PERC 600-650W\*\* median (21.4%) - Power density of 203.9 W/m² is 9.9 W/m² below \*\*PERC 600-650W\*\* median (213.8 W/m²) - needs more roof space - At -0.35%/°C, hot weather performance is typical for \*\*PERC 600-650W\*\* panels - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface - In the top 83% for efficiency among all PERC panels ## Questions ### How does the ELAN PRIDE panel differ from a standard monofacial panel? ELAN PRIDE features a bifacial construction, so its P-type PERC cells also capture light reflected off the ground from the rear side of the module. This can add 5-15% extra energy yield depending on the albedo of the surface beneath the installation, without increasing the array footprint. A standard monofacial panel only harvests light on the front side, resulting in a lower real-world annual yield for the same rated power. ### What warranty comes with ELAN PRIDE panels? Adani Solar provides a 12-year product warranty covering material and manufacturing defects, plus a 30-year linear power output warranty. This means the manufacturer guarantees a minimum generation level over three decades, with power degradation scheduled per the warranty terms. This is standard practice among tier 1 manufacturers, a category Adani Solar belongs to. ### Are ELAN PRIDE panels suitable for coastal and agricultural installations? Yes, the ELAN PRIDE series is engineered for harsh environmental conditions. A corrosion-resistant, anodized frame and a sealed IP68 junction box give it good resistance to salt mist and ammonia exposure. This makes the panel well suited for solar farms located near coastlines as well as agricultural installations, such as on livestock buildings. ### What is half-cut and multi-busbar (MBB) technology in ELAN PRIDE panels? Half-cut means the PERC cells are split into two halves, reducing current losses and limiting the impact of partial shading on overall module performance. Multi-busbar (MBB) technology combined with advanced soldering reduces microcracks and LID/LeTID degradation. Together, these features translate into higher reliability and a longer real-world service life compared to conventional full-size cells. ### What is the maximum power output of ELAN PRIDE panels and what installations are they suited for? The highest-power variants in the ELAN PRIDE series reach up to 650 Wp, making them suitable for both large-scale solar farms and demanding rooftop installations on commercial and industrial buildings. A higher per-module power output reduces the number of panels needed to reach a target system capacity, lowering mounting structure and installation labor costs. ### Is Adani Solar a tier 1 manufacturer, and where is it based? Yes, Adani Solar is classified as a tier 1 manufacturer, indicating financial stability, large-scale production, and bankability recognized by financing institutions. The company is headquartered in India and is one of the country's largest producers of solar cells and modules, allowing competitive pricing while maintaining high quality standards. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/pride-g2tb-modules-3d4d24830856.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +4.8 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +4.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +4.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +4.6 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +4.4 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | Cooler, lighter, +4.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +4.4 pp | | [Adani Solar ASM-M12-132-630](https://comparepv.com/panel/adani-solar-asm-m12-132-630) | 630 W | Very close match | | [Adani Solar ASM-M12-132-640](https://comparepv.com/panel/adani-solar-asm-m12-132-640) | 640 W | Very close match | | [Adani Solar ASM-M12-132-645](https://comparepv.com/panel/adani-solar-asm-m12-132-645) | 645 W | +10 W, +0.3 pp | | [Adani Solar ASM-M12-132-650](https://comparepv.com/panel/adani-solar-asm-m12-132-650) | 650 W | +15 W, +0.5 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +170 W, cooler, +4.7 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +165 W, cooler, +4.5 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +160 W, cooler, +4.4 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +155 W, cooler, +4.2 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +125 W, cooler, +4.1 pp | --- Source: https://comparepv.com/panel/adani-solar-asb-m12-132-635 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.
