Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (665 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 665 W at STC.
How this is modelled
Compounds this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures against its 665 W rated (STC) output, then derates for the ambient and irradiance selected. Output is scaled roughly linearly with irradiance (1000W/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 (-0.26%/°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.

Market context
Global evidencechange in the site menu
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 uses the highest published power bin in the series. No 132DDGB back-contact model appears on the Australian approved-module list, so no market-scoped range is published. Scored model: UL-665M-132DDGB · checked 2026-08-18. Evidence.

Strong evidence coverage
16 of 16 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.
Record revision. Built 2026-08-18 from Ulica Solar's datasheet version UL-2382-132DDGBBB-30-EN-V1.0. Read from a 165 dpi render, never parsed: the file's text layer silently DROPS EVERY NUMERAL, rendering the cover string as "Advanced: N-TaiRay + HPBC . + BB" where the page reads "HPBC 2.0 + 0BB". Any figure scraped from this document's text would have been fabricated. Retrieval note: the first download returned 6,045,696 bytes, passed a %PDF magic check, and was TRUNCATED - no trailing %%EOF, and the xref table did not resolve. The complete file is 10,979,516 bytes. A valid %PDF header is not evidence of a complete file. The datasheet prints no legal entity, only the trading name Ulica Solar and www.ulicasolar.com, so no company form is asserted here.
