Company Profile

Ecolong LLC has developed a smart sensor system to accurately monitor solar resources, as well as a peer to peer transactive energy platform. The ecoLong Sky Imager Radiometer (e⁻SIR) is a smart sensor system that measures accurate spectral and angular solar radiation distribution, sky conditions, and meteorological parameters for monitoring and forecasting solar radiation and weather conditions. The e⁻SIRs have been deployed onto the New York State Early Warning Detection System, NYS Mesonet, a world-class mesoscale network. This cutting-edge technology has broad applications in weather, climate, solar energy, and air quality. The e⁻SUN platform utilizes information technology to aggregate solar radiation, meteorology, and PV characteristics for performance monitoring, PV system evaluation, and production forecast
