Key features

Unmatched Accuracy

Accurate solar radiation and temperature data are a key pre-requisite for reliable PV yield calculation. pvPlanner makes use of validated solar radiation data that have lower uncertainty compared to other satellite derived irradiation data sources.

Simple but powerful

pvPlanner was designed for engineers as well as non-engineers. Options for user inputs have been simplified in a way that accuracy of results are not compromised. This means that pvPlanner is simple but powerful.

Automatic calculation of terrain shading

In-built digital terrain data with 90m resolution enables automatic calculation of shading losses from nearby hills/mountains. Horizon editor also allows you to manually edit the horizon and import horizon data measured at project site.

Professional reports in multiple languages

You can download pvPlanner reports in Spanish, Portuguese, Japanese, French, and 10 other regional languages. You can also customize the reports by importing your company logo.

API Access

pvPlanner service is also available as an API – allowing you to access SolarGIS data via 3 rd party apps. The API service is also useful for quick assessment of long-term energy production of a large portfolio of distributed PV systems.
