High resolution
Solar data with 250-m grid resolution for reliable energy assessment showing detailed solar climate variability, e.g. in islands, coastal zones and mountains.
Interactive solar potential maps
When evaluating solar development opportunities in new regions, interactive solar potential maps help to gain strategic insight into options for siting of projects, choice of technology, and planning of business or policy. iMaps is a user-friendly and reliable solar prospecting tool that saves time and helps reduce risks.

Solar resource may be diverse even in the small areas (GHI map, North-west Alps, Europe)
Air temperature is an important indicator to localize solar energy projects (TEMP, South America)

Complex terrain can induce certain limitations, especially for large-scale energy projects (Indonesia)
Other geographic data can be supplemental information in site selection process (Landcover map, Central Europe)
People are the main consumers of energy, therefore population maps matters (Population map, Asia)
Key features
Unmatched accuracy
Use of Solargis validated data, which has been independently recognised as the most reliable, in the prospecting stage, prevents disappointment in the later stages of a solar energy project development.
Download monthly average data
Monthly averages of solar resource and air temperature help to understand seasonal variability.

Frequently asked questions
Does the solar radiation data in iMaps include far shading losses?
Far shading losses from terrain is accounted for in the solar radiation data available via iMaps. For calculation of far shading losses, horizon data is taken from digital elevation models with spatial resolution of 250m.
