3TIER, a global leader in renewable energy risk analysis, today released solar performance maps of the US for June, July, and August 2011. The anomaly study, which illustrates how solar irradiance varied from its long-term norm, shows strong correlation with a series of weather events that impacted the US this past summer. The findings demonstrate that solar energy is not immune to climatic variability, the risk of which needs to be factored into the financial structure of projects and regularly monitored.
