This page describes the patchwork of federal, state, and local policies and regulations pertaining to renewable energy systems that impact project development.
The safe and reliable installation of photovoltaic (PV) solar energy systems and their integration with the nation''s electric grid requires timely development of the foundational codes and standards governing
The intent of solar energy ready requirements is to provide a penetration free and shade free portion of the roof, called the solar zone. This helps ensure future installation of a solar energy system is not
State Solar Carve-Out ProgramsSolar Interconnection Standards & PoliciesUnderstanding Electricity Market Frameworks & PoliciesInterconnection standards define how a distributed generation system, such as solar photovoltaics (PVs), can connect to the grid. In some areas of the United States, the interconnection process lacks consistent parameters and procedures for connecting to the grid or is unnecessarily complex. This drives up costs and causes delays, which can be sign...See more on epa.gov
