Adani Solar Showcases its High-Efficiency Elan and Eternal Series Modules

Let’s take an in-depth look at the technologies, behind the innovations of Adani Solar’s recently announced High Efficiency ultra-high-power modules designed for applications in small to utility-scale power plants with
• Power output up to 540W and 660W
• 21%+ efficiency • SHINE Series - Module size of 2266×1135mm with 182mm Cell
• PRIDE SERIES - Module size of 2390mm X 1303mm with 210mm cell.

The company’s R&D and Technology team has optimized the gallium-doped M10 standard silicon wafers (182mm) and G12 standard silicon wafers (210mm) that produce P-Type Mono PERC module with the lowest LID and LETID performances. It has also been proven that Gallium-doped silicon wafers shows lower LID performance with stable, long-term power generation as compared to boron-doped ones.

It’s Gallium-doped wafers are coupled with Non-Destructive cell cutting Technology that delivers superior performance.

With these gallium-doped cells, Adani Solar modules have increased annual generation performance, power performance and long-term reliability. The 1st year power warranty is an industry-leading 98% and linear annual degradation is within 0.45% after Year 1.

It has also adopted a superior soldering technology on its modules that has increased the module conversion efficiency by 0.3%. This technology uses wires that maximize light capture and reliably connect cells with reduced gap distance. More importantly, soldering reduces the tensile stress of the cell and ensures higher reliability.

The company has already developed the infrastructure to manufacture the M10 (182mm) and G12 (210mm) design with high efficiency cells of 23% and above reaching power class bins of 540Wp and above, making it an early adopter in Global Solar technologies in India.

Product design
The initial point in the development of Adani Solar modules was well planned after extensive insights from the PV industry and analysis of customer inputs and voices globally. The company further considered real-world applications to come with its new – Elan Pride (Bifacial modules with G12 cells) & Elan Shine (Bifacial modules with M10 Cells) and Eternal Pride (Monofacial modules with G12 cells) & Eternal Shine (Monofacial module with M10 cells) modules in the logistics chain.

The new world class modules from Adani Solar save 4.1% on BOS cost, 20% on Labour, 5% on Land & Logistics and 3% on LCOE.

The working current of Adani Solar modules are as high as 13-17A, including the bifacial gain. The operating current remains within the maximum input current range of the inverter, with no power generation losses. The module length is compatible with 1P and 2P horizontal single axis tracking systems.

Adani Solar modules come with “Double glass with frame” design that provides exceptional strength for high load capacity. The strength of the frame negates the need for a crossbeam, hence no shading losses at the back of the module.

In terms of BOS simulations using fixed brackets and centralized inverters, Adani Solar modules can reduce BOS costs by more than (US$1.5 cents/W) when compared to mainstream products in the market.

With string inverters, Adani Solar modules can improve the capacity ratio of the power plant, reduce AC equipment cost, and bring about the lowest LCOE for large power plants.

Innovation in volume production
The company believes in continuous innovations that can be quickly brought into volume production delivering true value for its partners and customers.

The module production capacity of Adani Solar is expanding from 1.5 GW to 3.5 GW in 2021. Elan (Bifacial) and Eternal (MonoFacial) series will be produced in volume and receive IEC/UL certification shortly in the next few months during 2021. The company is also planning to expand its manufacturing capacity up to 6 GW in 2023-2024.

The company’s Elan and Eternal range includes 66C and 72C formats, in bifacial and monofacial applications. The 72C (M10) version deploys traditional 6 rows design in a 72-cell layout with front-side power up to 540W, which is the optimal choice for ultra-large power plants worldwide. The 66C (G12) module has front power of 660W and a smaller footprint that broaden its applications.
