    1. Hi Bob,

      Thanks for your question. Global Horizontal Irradiance (GHI) is the “gold standard” of solar radiation measurements. It refers to the total amount of solar radiation falling on a flat surface. It’s generally measured in watts per square meter. Daily, monthly and annual averages are used to optimize the design of solar energy systems.

      If you know the GHI of a site, you can estimate the radiation falling on an inclined surface at various angles. This is particularly useful when you want to estimate the performance of your solar panels at different installation angles in order to find the best angle.
