Space saver, weak in heat
The ETERNAL SHINE series by Adani Solar is a monofacial photovoltaic module lineup built for rooftop installations where the balance between performance and price, along with resilience to demanding operating conditions, truly matters. The panels use P-type PERC half-cut cells, which reduce resistive losses and improve module behavior under partial shading, a common issue on residential roofs and small commercial buildings. The multi-busbar structure with smart soldering (10BB) increases the reliability of electrical connections and lowers the risk of microcracks during transport and installation. A key advantage of the series is gallium-doped silicon, which significantly limits light-induced degradation (LID) and elevated-temperature and current-induced degradation (LeTID), delivering more stable energy yield throughout the module's service life. The panels also feature high resistance to potential-induced degradation (PID) and a grid-pattern current path that evenly distributes internal stress. Thanks to solid low-irradiance performance, the modules perform well on overcast days and during early morning or late afternoon hours. This makes the series a fitting choice for investors looking for proven, monofacial PERC technology with a strong balance of cost, durability, and predictable energy output.

Gallium-doped M10 wafers reduce LID and LeTID degradation, with manufacturer data indicating first-year power loss below 2.0% and annual degradation below 0.45% through year 30 of operation.
Peak module efficiency of 21.42% exceeds comparable tier-1 series: IBC Solar 182M Half Cell (21.28%), Goldi Solar GS10-B144-TF (21.3%), and Jetion JT SGh (21.3%), within the same 520-550Wp power class.
Adani Solar is listed on BloombergNEF's Tier-1 bankable manufacturer list (Q1 2026 update) and has been named a Kiwa PVEL Top Performer for seven consecutive years, reducing project financing risk.
The multi-busbar 10BB layout combined with half-cut cells and smart soldering reduces resistive losses, improves partial-shading behavior, and lowers microcrack risk during transport and installation.
The ETERNAL SHINE series has been on the market since 2021 and remains active, ensuring continued service availability, replacement parts, and warranty fulfillment throughout its lifetime.
The 12-year product / 25-year power warranty is typical for PERC technology but notably shorter than the 15/30-year terms already offered by newer N-type TOPCon lines, including the manufacturer's own Elan Shine series.
PERC is a mature platform approaching its practical cell-level efficiency ceiling (~23%), and the module is monofacial only - lacking the rear-side yield gain offered by increasingly common bifacial N-type designs in this power class.
- At 21.2% efficiency, this panel is on par with typical PERC 500-550W modules
- Power density of 212.3 W/m² packs 3.3 W/m² more into the same footprint vs PERC 500-550W median (209.0 W/m²)
- At -0.37%/°C, loses 0.02pp more power per degree than PERC 500-550W median (-0.35%/°C)
- In the top 65% for efficiency among all PERC panels
