Annual average values of solar resource and temperature are now available for free via iMaps
Over the last years we have invested a lot in creating the most reliable and detailed global solar resource database. We have made some of the data public in the form of free image maps that are widely shared within the solar industry.
From today onwards, we are also opening access to long-term annual averages of key solar parameters GHI, DIF, and DNI via Solargis iMaps prospecting tool. This will be the first time that a global solar radiation database with spatial resolution higher than 1 km is accessible for free.
The full version of iMaps will additionally provide monthly averages which can be used with various solar simulation software such as PVsyst.
