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

So as to certify the solar potential of a previously identified site, one must gather a precious information concerning the specific location: that the site’s solar irradiance is sufficient to confirm the project’s potential and bankability. Reuniwatt offers climatic and meteorological solutions to help solar developers put in place renewable energy projects.
