Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (445 W) applied to the guaranteed floor; modular/format differences aside, this is the same rated-power spec shown above.
Modelled effective output, year by year
Year 1 to year 25, at 30°C and 1000 W/m². Rated 445 W at STC.
How this is modelled
Compounds this panel’s own published first-year (1%) and annual (0.4%/yr) degradation figures against its 445 W rated (STC) output, then derates for the ambient and irradiance selected. Output is scaled roughly linearly with irradiance (1000 W/m² against the 1000 W/m² STC reference). This is the dominant real-world effect at low light, whether from cloud, shading or soiling. Output is then further derated for heat, from this panel’s own NOCT (45°C) and temperature coefficient (-0.3%/°C), giving an estimated cell temperature of 61°C at that ambient and irradiance. A datasheet-derived estimate, not a field measurement or a warranty guarantee: it does not account for this panel’s own low-light efficiency response (a separate, less-consistently-published spec), or for wind and system design. See NOCT and temperature coefficient in the glossary.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score is anchored to the highest published rating in this exact published US series. Scored model: SEG-445-BTD-BG · checked 2026-08-23. Evidence.

Strong evidence coverage
21 of 21 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them.

- Intertek Authorization to Mark for Report 2308A1577HAN-001S (ATM issued 9 February 2026, PDF pages 1 to 3) names the SEG-XXX-BTD-BG series for XXX values 420, 425, 430, 435, 440, 445, 450 and 455, which includes SEG-445-BTD-BG. Page 1 carries the Intertek ETL Listed (C US) mark. Page 2 lists UL 61730-1:2022 Ed.2, UL 61730-2:2022 Ed.2+R:02Jun2025, UL 61215-1:2021 Ed.2, UL 61215-1-1:2021 Ed.2 and UL 61215-2:2021 Ed.2. The authorization covers the model code only and prints no color or frame variant. The copy is hosted on SEG's certificate download page and was not cross-checked against an Intertek public directory on 9 October 2026.; The same sheet also lists PID (IEC 62804), salt mist (IEC 61701), ammonia resistance (IEC 62716), dust and sand (IEC 60068) and hailstone (IEC 61215) entries without test severities, and Fire Type (UL 61730) Type 29. It carries cETLus Listed (Intertek), TUV SUD, DEKRA, CE, PV CYCLE, California Energy Commission and FSEC logos, but prints no certificate numbers and does not say which standards each logo covers. The California Energy Commission PV Module List export (data unchanged since 1 October 2026) lists SEG Solar Inc. SEG-445-BTD-BG with safety certification UL 61730, listed 21 May 2025 and last updated 1 April 2026. The list's data key says the model number and safety certification are confirmed by a certificate of compliance; the list names no certifying body or certificate number and is not evidence of sale.; UL 61215, UL 61730, IEC 61215 and IEC 61730 are listed on the exact SEG-445-BTD-BG datasheet.

US Warranty conditions
- Current text
- labour: Excluded unless SEG agrees in writing.; registration: No pre-registration prerequisite is stated in this instrument. Written claim notice is due within the earlier of five business days after awareness or the warranty end date, by registered letter or the stated email. Include photographic/empirical evidence, serial number and delivery date; preserve the faulty module for SEG inspection and return it only when requested. Maintenance records/logs must be kept and supplied on request. The claim package also requires purchase/sale-chain proof, installation/site/installer details, licensed-electrical-work evidence, manual compliance and requested diagnostics. Transfer still requires prior written notice and its separate conditions.; remedy: SEG selects the remedy. Product-defect options include repair, replacement or refund; refurbished parts may be used, and replacements retain the original warranty end date. A qualified third-party product repair at SEG expense is conditional on 90 days after defect confirmation without remedy, then five business days’ written notice; it is not an unconditional 90-day deadline from initial claim. Peak-power options include repair, replacement, additional modules or lost contracted revenue for the shorter remaining power-agreement/warranty term, discounted at 9% annually. A discontinued product may be replaced by a different module type. Refund value remains unresolved: clause 3 describes the lower of buyer price/substitute cost, while clause 7 uses SEG’s depreciated net selling price, generally credited to the authorised dealer/distributor. No full retail refund is inferred. For disputed testing, SEG pays when a covered defect is established; otherwise the buyer pays. Clause 5 states that these are the buyer's sole and exclusive remedies and exclude all other express or implied warranties, including merchantability and fitness for purpose; that, to the maximum extent permitted by applicable law, SEG is not liable for incidental, consequential or special damages, including loss of production and revenues; and that SEG's aggregate liability does not exceed the amount the buyer paid for the single module. The document does not say how these limits apply to the lost contracted revenue power remedy.; removal reinstallation: Excluded; moving or reinstalling the module can void coverage.; transferability: Conditional on prior written notice, the original installation location, qualified original installation, and required ownership and commissioning evidence.; transport: Not safely established. The document says SEG pays certain delivery shipping, but later excludes shipping unless expressly agreed in writing.

- After
- The reviewed SEG-445-BTD-BG datasheet is a US product record. Australian availability and warranty scope for this exact SKU have not been published in the benchmark. SEG's US residential double-glass warranty 2026 V1.01 states that it becomes null and void if the module is installed outside the United States, so it does not cover this module installed in Australia.

- SEG Manufacturing Inc. US residential double-glass warranty 2026 V1.01, valid from April 2026 until a new version is issued, names YUKON N SEG-XXX-BTD-BG_182 (Full Black) with 30-year product and 30-year peak-power cover. The exact full-black SEG-445-BTD-BG sheet joins this family. Cover starts at the earlier of delivery or 180 days after manufacture. The N-type power obligation is tested at STC, with 1% first-year loss then 0.4 percentage points annually to 87.4% at year 30; it is not a field-yield guarantee. Actual purchase/version applicability and conflicting shipping/refund terms need confirmation.
