Gathering solar irradiance and wind data represents the first step of renewable project development. They enable to validate a site’s resource potential and translate into a compulsory request from investors.

So as to certify the resource potential of a previously identified site, one needs to gather valuable information concerning the specific location: Are the site’s solar radiation or wind resources sufficient to confirm the potential and financial viability of the project? Reuniwatt offers climatic and meteorological solutions to help project developers put in place renewable energy projects.
