Global Solar Map

Portfolio Image

Project Description

The solar map provides average annual GHI (global horizontal irradiance) at a 3km spatial resolution. GHI is the most important variable for determining the energy production of PV (photovoltaic) panels. This map is a subset of a larger global solar dataset created by 3TIER, a Vaisala company and global leader in renewable energy assessment and forecasting. Averages are based on more than 10 years of hourly GHI data derived from visible satellite imagery using a combination of in-house research and algorithms published in peer-reviewed scientific journals.
