Understanding Snow Model Variations We analyzed two snow models for this report: NREL and Townsend. The NREL model uses a history of daily accumulated snow depth and temperature in its calculation and considers snow sliding as the dominant process of snow removal, neglecting snow melting and wind effects.2 The Townsend model, on the other hand, […]
According to the World Energy Outlook report by the International Energy Agency (IEA), global annual solar PV capacity growth is expected to more than quadruple in 2030 to 650 GW. Nearly 50% of the global solar capacity is slated to come from utility-scale installations. One trend that is expected to dominate new commercial and utility-scale […]
