As solar projects grow in scale and move into emerging markets worldwide, it is increasingly important for long-term solar and meteorological data to be validated on a regional basis, with the right uncertainty estimates.

We can provide you with a detailed solar resource assessment and validation report as an add-on to our standard data delivery. 

To support the bankability of the assessment, we include solar and meteorological data validation from nearby sites.

Regional validation statistics provide a better indication of the expected quality of GHI and DNI model estimates.

Specific uncertainty of solar and meteo estimates

Our reports include uncertainty and probability of exceedance values for multiple scenarios.

We derive this key information from an analysis of the representativeness and accuracy of regional measurements, model validation, and interannual variability.

If available, we integrate on-site measurements of solar and meteorological data to perform site adaptation of the Solargis model.

This enables the delivery of long-term time series with reduced uncertainty, giving project stakeholders more confidence.

“We had been in touch with several meteo providers and we found that Solargis provides the most representative estimates for each site.”

Near real-time PV output assessment

Combine satellite data with on-site measurements to reduce the uncertainty of estimated energy output and achieve more accurate financial estimates.

The Site Adaptation of Solargis Models service will give you locally enhanced solar and meteo parameters, enabling you to reduce uncertainty of power plant design and energy yield simulations.

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 yield assessment with our proprietary simulation tools and models. These are based on 15+ years of experience working on large and medium-scale PV power plants around the world.

Data-driven insights from our PV Performance Assessment report conducted after months or years of the plant's operation will help you optimize its performance.

The report also provides a revised and more accurate long-term energy yield estimate for refinancing or new asset acquisition purposes.
