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 (520 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. Rated 520 W at STC.
Modelled from this panel’s own published first-year (1%) and annual (0.4%/yr) degradation figures, compounded against its 520 W rated (STC) output. This is a datasheet-derived estimate, not a field measurement or a warranty guarantee. Actual output also depends on site irradiance, temperature, soiling and system design.
| Year | 1 | 5 | 10 | 15 | 20 | 25 |
|---|---|---|---|---|---|---|
| Watts | 515 W | 506 W | 496 W | 486 W | 475 W | 465 W |
| % of rated | 99.0% | 97.4% | 95.4% | 93.4% | 91.4% | 89.4% |
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 Ultra T 2.0 108 half-cell model and wattage, and who covers labour if the module warranty is used?
