Adani Solar — Elan Shine TOPCon Series Gen-II (ASB-M10-144-AAA, 550–580W)

A modern TOPCon module that lists BIS in its approvals — plus a wind/snow load rating that needs an engineer’s interpretation, not a headline-number comparison.

Reviewed 23 August 2026

4.1of 5 · our score

The Elan Shine TOPCon Gen-II is Adani Solar’s N-type dual-glass bifacial module, using 144 half-cut M10 cells across a 550W–580W bin range, reaching 22.5% module efficiency at the top bin. It carries a 30-year linear performance warranty (≤1% year-1 degradation, ≤0.40%/year after, landing at 87.4% by year 30 — the same strong endpoint we found on Waaree’s TOPCon line) plus a 12-year product warranty.

One thing worth noting about this datasheet: it lists BIS (Bureau of Indian Standards) among its approvals, alongside IEC and UL standards. The same datasheet adds "a few certifications in process," so this is a box to verify for your exact batch rather than a guarantee that every listed certificate is finalized — and BIS marks also appear on other datasheets we have reviewed (Tata’s, for example), so it is not a differentiator on its own. Ask any vendor for the certificate number for the batch you are buying.

Adani also publishes a fuller bifacial-gain table than the other panels here — expected power at 10%, 15%, 20%, 25%, and 30% assumed rear-side gain, rather than just a bare bifaciality ratio. That is more useful for your own yield modelling, though actual gain still depends entirely on your mount height and ground reflectivity, not the datasheet table alone.

For Installers & Engineers

Deeper technical detail beyond the homeowner-facing summary above.

Temperature coefficient of Pmax is −0.32%/°C — at a realistic 65°C summer cell temperature, that works out to roughly 12.8% derate from STC, closely matching the Waaree TOPCon module we reviewed (≈12%, −0.30%/°C) and meaningfully better than the Mono PERC panels reviewed here (Vikram ≈14%, Tata ≈15%). Consistent with N-type TOPCon’s known thermal advantage over P-type PERC.

Mechanical load is stated as 3,600 Pa downward / 1,600 Pa upward — a different rating convention from the "5,400 Pa snow / 2,400 Pa wind" figures on the Tata, Waaree, and Vikram datasheets reviewed elsewhere. These are not simply interchangeable numbers: downward/upward and snow/wind test directions and standards can differ. If wind or coastal exposure is the reason you are considering this module, have a structural engineer interpret this rating against your actual site requirement rather than comparing the headline Pa figure directly against other brands.

Bifaciality factor is 80±5% — a notably tighter tolerance band than the 80±10% we found on Waaree’s TOPCon module or the 70±10% on Tata’s Mono PERC bifacial module, which may indicate more consistent batch-to-batch rear-side output. The same installation-height and albedo dependency applies as with any bifacial module — the lab figure is a ceiling, not a promise.

Cell architecture is 144 half-cut M10 N-type TOPCon cells — the same general half-cut shade-tolerance mechanism covered in our other panel reviews, combined with TOPCon’s passivated-contact efficiency advantage over PERC.

The Scorecard

How we score

Efficiency & Real-World Yield

4.5

Strong 22.5% top-bin efficiency with a genuinely good −0.32%/°C temperature coefficient, close to the best TOPCon figures found across all panels reviewed.

Durability & Degradation

4.0

Solid certification stack including BIS, but the datasheet’s own "certifications in process" caveat and an unfamiliar mechanical-load convention hold this back from full marks pending confirmation.

Warranty & Bankability

4.5

A 30-year linear warranty landing at the same strong 87.4% endpoint as the best terms found elsewhere in our reviews, plus a 12-year product warranty.

Subsidy & Policy Fit

3.5

BIS is listed among the approvals, but — as with every panel we review — the datasheet does not state ALMM List-I or DCR status, and a few certifications are marked "in process." That is the same standing gap as the other panels, so there is no uplift over them.

Value for Money

4.0

No independently sourced ₹/W pricing, but Adani’s manufacturing scale should keep this competitive within the TOPCon segment specifically.

Strengths

  • BIS and IEC/UL standards spelled out in the manufacturer’s approvals list (subject to the "in process" note) — confirm the certificate for your batch
  • Strong TOPCon-class temperature coefficient (−0.32%/°C), close to the best figure we’ve found across all panels reviewed
  • More transparent bifacial-gain documentation (a full table across five assumed gain levels) than the other panels reviewed here
  • 30-year linear warranty landing at the same strong 87.4% endpoint as the best terms we’ve found elsewhere

Watch-outs

  • The datasheet flags "a few certifications in process" — confirm exactly which ones, including whether BIS itself is fully finalized (not just a listed target) for your specific batch
  • Mechanical load is rated on a different convention (downward/upward Pa) than the snow/wind Pa figures on other panels we’ve reviewed — do not compare headline numbers directly across brands without a structural engineer’s interpretation, especially for coastal or high-wind sites
  • No explicit ALMM List-I statement beyond the BIS listing — confirm the specific bin’s current ALMM status separately before assuming PM Surya Ghar or other subsidy eligibility
  • The 550–580W range spans 7 wattage bins under one datasheet — confirm exactly which bin you are quoted

Who It’s For

  • Buyers who want BIS and IEC/UL standards spelled out in the manufacturer’s own approvals list
  • Commercial/industrial buyers wanting current-generation TOPCon efficiency with detailed bifacial-gain data for their own yield modelling
  • Buyers who will have a structural engineer independently verify wind/snow load suitability for their specific site rather than relying on segment positioning alone

Our Verdict

A strongly specified TOPCon module with BIS and IEC/UL standards listed in its approvals, a −0.32%/°C temperature coefficient and a 30-year linear warranty. Confirm which certifications are still "in process" for your batch and the ALMM/DCR status of the exact bin, and if wind or coastal exposure is why you are considering it, get a structural engineer to interpret its downward/upward Pa rating rather than assuming it is the highest-rated option.

Frequently Asked Questions

Is the Adani Elan Shine panel BIS certified?

BIS is listed among the approvals on Adani’s own datasheet, which also notes "a few certifications in process" — so confirm BIS is fully finalized, not just a listed target, for your specific batch before ordering. Other manufacturers’ datasheets we reviewed also carry BIS marks, so ask every vendor for the certificate number.

Is this the best panel for a high-wind coastal installation?

Its mechanical load rating (3,600 Pa downward / 1,600 Pa upward) uses a different convention than the "5,400 Pa snow / 2,400 Pa wind" figures on some other panels we’ve reviewed, so the headline numbers are not directly comparable at face value. Ask a structural engineer to interpret both rating types against your actual site’s wind-zone requirement rather than assuming either brand is automatically better for coastal exposure.

How much real bifacial gain will I get from this panel?

The datasheet gives a detailed table of expected power at 10–30% assumed rear-side gain, more transparent than most panels we’ve reviewed — but actual gain still depends on your specific mount height and ground reflectivity (albedo), not the lab bifaciality factor or table alone.
