How Solargis monitoring solutions help

Validate and gap-fill ground measured data

Maintaining systematic solar resource monitoring at high quality and without gaps is challenging, due to potential issues in data acquisition, storage and transmission. Data from ground-mounted sensors are prone to errors for reasons such as shading, misalignment of instruments, calibration issues, irregular or insufficient cleaning, missing data, etc. Solargis data allows for quality control, error detection and data gap filling.

Bring transparency and reliability to your performance metrics

Solargis data make it possible to independently confirm validity of performance ratio calculations based on ground measurements. As the satellite data come from an independent service provider, they can also be used for settling contractual arguments relating to doubts about measurements from pyranometers.

Enable performance monitoring of residential and commercial PV systems

Installing and maintaining the pyranometers is relatively expensive and challenging. Therefore, it is typically not an option for residential and small commercial photovoltaic (PV) projects. In a case of portfolio of smaller systems, use of Solargis data is a practical approach for performance evaluation.

Understand annual or seasonal variability of solar resource and PV power

It is often asked to what extent a particular month or year had received higher or lower solar radiation compared to the long-term average. Solargis data are the most suitable for such an exercise as they record stable, high-resolution, map based historical archive of up to 22 years.
