We provide forecasts and measurements for grid management, energy trading, monitoring and operation of PV systems, building automation and facility management.
Our three products can be used individually or in combination. A flexible API combined with an attractive pricing model guarantees an excellent price/performance ratio in all areas of application. Sites can be independently added and edited directly through the API.
SolarForecast provides accurate irradiation forecasts for the next 72 hours for energy producers, grid operators, energy providers and direct marketers as well as building automation. The system is based on global weather prediction models. The forecast values of the weather models are statistically optimized with real measurement data from weather stations.
The CloudMovetechnology predicts cloud movement using wind information from weather models and cloud positions from satellites. The result is an irradiation forecast for the next 6 hours which is updated every 15 minutes
SolarSat delivers satellite measured solar radiation values with hourly resolution.
