New generation Solargis Evaluate: data, PV design & simulation, analysis, and reports in one cloud-based solution. Discover more ->

For financial risk assessment, investors and developers require reports of expected energy production, including uncertainties, as well as related solar and meteorological data inputs.

We offer an independent and impartial evaluation of PV energy yield with our proprietary simulation tools and models. These are based on 15+ years of experience working on large-scale PV power plants around the world.

Low uncertainty of input data

Solar resource and air temperature are the most significant contributors to the uncertainty of PV energy simulations.

Solargis PV energy estimates are based on our own solar and meteorological Time Series, known for their rigorous validation and low uncertainty. 

Simulation in 1- to 15-minute time steps

In contrast to the common practice of using hourly TMY data in PV yield simulation, we use sub-hourly time series of solar radiation and air temperature.

Weather inputs with higher temporal resolution and a full history (more than 30 years) deliver higher accuracy and help you correctly evaluate atypical weather conditions.

For energy PV yield assessment, we use our proprietary simulation engine and algorithms. This enables us to provide you with detailed insights into energy losses, uncertainties, and PV plant design options.

If available, we integrate on-site measurements of solar and meteorological data for site adaptation of the Solargis model, delivering long-term time series with reduced uncertainty and, in turn, giving project stakeholders higher confidence.

“At all 10 projects, Solargis irradiation data closely matched on-site measurements, giving First Solar and other project stakeholders full confidence in the accuracy of Solargis estimates.”
