Version SunSat -Solar Irradiance Estimation Tool Using Satellite
SunSat™, Reuniwatt’s reliable satellite-to-irradiance technology, is based on the regular high-resolution earth observation provided by geostationary satellites, and delivers accurate local irradiance data for any location – worldwide. It can be used in two different ways: SunSat™ live: As a real-time monitoring service available for any site or portfolio of solar installations on the planet. SunSat™ time series: As a service to retrieve historical irradiation time series, for any site on the planet.
HARDWARE-FREE SOLUTION
No matter the number of solar plants in your portfolio, SunSat™ enables you to get a precise estimation without installing any hardware.
WORLD COVERAGE THANKS TO 5 GEOSTATIONARY SATELLITES
Reuniwatt receives the live images of five geostationary satellites, enabling an irradiance estimation service anywhere in the world.
ACCURATE AND RELIABLE DATA
SunSat™ provides accurate and reliable data for already monitored or unmonitored PV plants. Beyond 25 km, ground measurements are less precise than satellite data.
SunSat™ benefits of constant improvement to increase the accuracy of the data provided. It is based on an original technique eveloped by Reuniwatt (Cros et al., 2015) and derived/optimised from the work developed about 15 years ago the Mines Paristech under the direction of Lucien Wald, made by Rigollier et al. (2004) and Cros et al. (2004).
