The assessment
How it scores, by category
Market position
The data
Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (495 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 495 W at STC.
Compounds this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures against its 495 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.

System decision
Only exact, manufacturer-named Australian paths are shown. A shared brand, product family or output rating is not proof of compatibility.
Exact pairing not recorded
No exact manufacturer-named inverter, battery or integrated-system pairing is recorded for Australia. This is a documentation state, not a finding that the product cannot be used in a system.
A documented relation does not establish site sizing, network approval, protected-load design, firmware state or installer acceptance. When no exact relation is recorded, compatibility remains unestablished in this catalogue.
Ask the installer: Will the quote name the exact Quasar 108-cell model and wattage, and who covers labour if the module warranty is used?

Australian warranty scope: Australia; the model-linked warranty expressly names PSXXXL7GFH-18/VBH and states a 15-year product and 30-year performance term. Phono Solar's Australian product page separately advertises a 30-year residential product term, but no model-specific 30-year instrument was published in the reviewed downloads. The 15-year governing term remains the benchmark. Remedies include repair, replacement, additional modules or value-based refund, with conditional sea freight, written transfer at the original site, and customer-paid removal and reinstallation.
Structured claim terms: Recorded.

Strong evidence coverage
19 of 19 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.
