Solar Resource Assessment

Where is irradiance strongest? What are the specific conditions at your site? How much year-to-year power variability is expected and what are my exceedance values? Without addressing these questions, it is impossible to assess a project's feasibility or manage your exposure to risk. Vaisala's assessment services and bankable solar time series provide accurate and reliable answers these questions at any location worldwide.
