Careers

From talking with thousands of solar energy companies, we've learned that solar professionals want data and software tools that will help them predict solar energy yield easily and accurately. This is exactly what we are trying to help with.

Solargis for project development

If you are developing or helping develop new solar projects, you probably want to have a reliable estimate of long-term energy yield and optimise the design for maximum profitability. There are many software tools that help you with these tasks. One thing in common with most of these tools is that the default weather database is not very reliable. 

The solution is to use Solargis online apps or import Solargis data to your preferred PV simulation software. Multiple independent validation studies have shown that Solargis outperforms all other irradiation data sources available. If you use Solargis data for energy yield calculations, the risk of over or underestimating the potential yield is lower.

Solargis for operational projects

The Solargis database is updated in real-time and can provide estimates of expected PV production for recent history i.e last days or last months. These estimates can be compared with actual PV production data from a power plant to understand its performance.

Solargis data are a practical alternative to pyranometers for performance monitoring of rooftop PV systems. For large ground-mount PV systems, Solargis serves as an independent data source for validation and gap-filling of on-site irradiation measurements.

We also provide intraday and day-ahead forecasts of PV power production for individual solar power plants, or regional aggregations of hundreds of solar systems.
