Warranty pick, heavy for its output
The Adani Solar ELAN series consists of advanced bifacial modules that redefine performance standards by actively utilizing light reflected from the ground. The use of half-cut cell technology combined with multi-busbar architecture allows for a significant reduction in resistive losses and much better performance in partial shading conditions. These panels are an ideal choice for investors developing large-scale solar farms and industrial installations, where the priority is to maximize energy yields from limited mounting space. Thanks to the use of high-transmittance tempered glass on both sides of the module, the ELAN series demonstrates extraordinary resistance to PID degradation and aggressive atmospheric factors, which guarantees parameter stability over a long-term horizon. A key advantage of this series is its low temperature coefficient, ensuring high cell efficiency even during extreme heat waves. This solution effectively optimizes the LCOE, shortening the return on investment time by generating additional yield from the rear side of the panels. By choosing these modules, users gain above-average mechanical durability and operational reliability in the most demanding environmental conditions, which clearly distinguishes them from standard monofacial solutions. This is technology tailored for professional systems where every watt of power produced counts.

N-type PERT cells with bifaciality up to 85% generate an additional 10–30% of energy from the back side of the module (depending on the surface albedo), and the negligible LID effect results in degradation of less than 2.0% in the first year – better than typical P-type PERC modules (3–5%).
The manufacturer guarantees a degradation rate of <0.55% per year between years 2 and 30, while maintaining ≥87.4% of its nominal capacity after 30 years. This warranty is equivalent to the best standards in the premium segment, such as Panasonic EVERVOLT, at a lower purchase price.
In the Wood Mackenzie ranking for H1 2025, Adani Solar ranked 8th globally, and as the only Indian company, it achieved a Grade A rating in the categories of technological capabilities, vertical integration, and supply chain resilience. This Tier 1 status from BNEF, maintained since 2018, is a key criterion for bankability in financing photovoltaic farm projects.
The design, featuring tempered glass on both sides without an aluminum frame, eliminates PID degradation and prevents corrosion of the frame in marine and high-humidity environments. An additional benefit is higher bifacial gain due to the absence of shading from the bottom of the module by the frame.
The maximum efficiency of the ELAN series (18.34%) is lower than that of all comparable products: Solarwatt GM 3.0 style (19.9%), Solitek SOLID Bifacial (19.57%), and Panasonic EVERVOLT (21.2%). The 1.6–2.9% difference in efficiency necessitates a 9–16% larger mounting area for the same installed power – a significant cost in installations with limited space.
The series is based on the N-type PERT architecture released in 2018, while newer series from the same manufacturer (ELAN SHINE TOPCon) already achieve efficiencies of 22.28%. The lack of architectural upgrades to the cell for over 7 years results in a lower temperature coefficient and a higher annual degradation rate compared to current TOPCon modules.
Given the current dominance of 400–700 Wp modules in the utility-scale and commercial segments, the ELAN series requires 15–30% more modules per MW of installed capacity compared to current competitor products. This translates to higher BOS (Balance of System), installation, and logistics costs in large-scale projects.
- Module efficiency of 17.8% is 1.6pp below average for N-type 0-400W panels (median: 19.5%)
- Power density of 178.4 W/m² is 16.5 W/m² below N-type 0-400W median (194.9 W/m²) - needs more roof space
- At -0.40%/°C, loses 0.08pp more power per degree than N-type 0-400W median (-0.32%/°C)
- At 31.1 kg, this panel is 9.1 kg heavier than the N-type 0-400W median (22.0 kg) - more demanding for installation crews
- 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces
