Bergey Excel 15 — ICC-SWCC certification Summary Report (2022)
The current, independently-certified small-wind reference curve (RT_290, option B)
ICC-SWCC Summary Report SWCC-16-05 (© 2022 Small Wind Certification Council), certifying the Bergey Windpower Excel 15 to the AWEA Small Wind Turbine Performance and Safety Standard (AWEA 9.1-2009). Independent third-party certification — the strongest provenance for a small-wind power curve, paired with the NZ-made Thinair (DS_001) for local context.
Summary
The ICC-SWCC certification Summary Report for the Bergey Excel 15, the current (2018-on) successor to the older Excel 10. It provides an independently-certified power curve and a standardized Rated Annual Energy at a 5 m/s average wind speed — the reference point that lets the model convert a site’s mean wind speed to a capacity factor on a like-for-like basis. This is the certified reference machine at community scale; the NZ-made Thinair (DS_001) is the smaller local option.
Key claims
- claim: "Certification and ratings: the Excel 15 is 'certified under the ICC-SWCC Small Wind Turbine Certification Program to be in conformance with the AWEA Small Wind Turbine Performance and Safety Standard (AWEA 9.1-2009)'; it is 'a 3-blade, upwind, stall-regulated, horizontal axis wind turbine with a rotor diameter of 9.6 m and swept area of 72.4 m2'; mechanical strength conforms to IEC 61400-2 for an IEC Class II Small Wind Turbine. Rated values: 'AWEA Rated Annual Energy @ 5 m/s 29,800 kWh'; 'AWEA Rated Power @ 11 m/s 15.6 kW'; 'AWEA Rated Sound Level 48.5 dB(A)'. => derived capacity factor at 5 m/s = 29,800 / (15.6 kW x 8,760 h) = 21.8%."

- claim: "Certified power curve (measured electrical power, kW, by wind-speed bin m/s): 8.5->9.7, 9.0->11.3, 10.0->13.7, 11.0->15.6 (rated), 12.0->16.9, 13.5->18.9, 15.0->20.4 (peak). AWEA Rated Annual Energy is the energy in one year at a 5 m/s average wind speed assuming the standard Rayleigh distribution (AWEA 9.1 / ICC-SWCC reference) — the standardization that makes certified turbines directly comparable."

The certified reference power curve for RT_290 at community scale. Integrated against a Rayleigh distribution at the sampler’s site mean wind speed (method: US DOE, URL_017), it yields a site capacity factor for the D25 “#9” wind override. Its 21.8% CF at 5 m/s anchors the upper end of the wiki’s ~10–30% NZ small-wind range (CR_013) and is well below the ~40% utility wind CF (which must not be used for small wind).
Provenance value: unlike a bare datasheet, ICC-SWCC certification is independent third-party testing to AWEA 9.1 / IEC 61400, and its 5 m/s Rated Annual Energy is the industry-standard comparison point — the credible way to source small-wind specs (the ICC-SWCC directory, UK MCS, and IEC 61400-12 are the equivalents). Improvement note: same family, same 5 m/s reference, the superseded Excel 10 (2013) gave ~17.7% CF vs the Excel 15’s 21.8% — a real ~4-CF-point/decade gain (lower specific power), still inside the resource-limited band. Caveat: US turbine (a reference, not an NZ market recommendation); use rated (not peak) kW as the CF denominator; extrapolate site wind to hub height (output ∝ V³).
