PVQuick November 2026 version. Row 1: we ran PVQuick on five photovoltaic systems at NREL’s Golden, Colorado campus, using the publicly available 2011–2012 on-site measured weather data. The same data set was used in NREL’s 2014 software validation study (Freeman et al., NREL/TP-6A20-61497). Row 2: PVQuick did not take part in the 2021 PVPMC blind modeling comparison; we ran it after the measured data were published (Theristis et al. 2023, doi:10.1002/pip.3729; data: Theristis & Stein 2023, doi:10.21948/1970772). Row 3: Technical University of Denmark (Riedel-Lyngskær et al. 2020, doi:10.3390/app10238487; data under CC BY 4.0, doi:10.11583/DTU.13580759). Results with default loss factors on request: support@pvquick.com. The PVQuick team carried out these calculations. They do not represent validation or endorsement by NLR, NREL, the Alliance, the U.S. Department of Energy, Sandia, DuraMat, PVPMC or DTU.
Scope
What it covers
Solar resource data cover any site globally; equipment and cost data cover China, the USA and Europe; project sizes range from a few kW to 300 MW.
Ground-mounted PV plants
Flat terrain with ten mounting types (by latitude), or sloped land following the slope or terraced.
Array-installed distributed PV
Tilted arrays with calculated row spacing: flat roofs, water-surface PV, elevated structures.
Flat-laid distributed PV
Modules flat on the roof plane: pitched roofs, greenhouses, façades, carports, PV balconies.
Worldwide Solar Resource QueriesSolar resource and hourly weather queries by name, map or coordinates worldwide, subject to data coverage. Quick design, equipment defaults and full financial analysis currently cover China, the USA and Europe.
