  • Key solar and meteorological parameters
Prospect potential sites with confidence

Prospect potential sites with confidence

Don't make compromises. Start as you mean to go on, from the very first decisions in the prospecting phase, using accurate and validated data that are compatible with later project stages.

Validated by independent studies, Solargis delivers the most accurate long-term average (LTA) data on the market, with the longest recorded history.

Make confident decisions from the start

Make confident decisions from the start

Access to long-term solar and meteorological data is crucial in early project development. It supports accurate site assessment and selection of high-potential locations.

Key parameters include solar irradiation, precipitation, air temperature, wind speed, albedo and others.

Integrate Solargis data easily
