Engineering certification for the installation of solar photovoltaic (PV) modules on wood roofs is often denied because existing wood roofs do not meet structural design codes based on conservative analysis and codes. This report provides results from a testing program that documents actual load-carrying capacity of residential rooftops built to existing building codes.
In the report, a team of researchers from Yale University, University of Wisconsin-Madison, University of Texas-Austin, and Lawrence Berkeley National Laboratory empirically examined heterogeneity in PV prices in the United States.
The Executive Summary from the report:
The National Renewable Energy Laboratory (NREL) recently released a report that breaks down the ‘soft costs’ associated with the installation of residential and commercial photovoltaic systems in greater detail than ever before, with detailed looks at customer acquisition and system design costs, as well as permitting, inspection and interconnection costs.
A new study from the Rocky Mountain Institute and the Georgia Tech Research Institute finds that U.S PV installation labor costs can be decreased from $0.49/watt to $0.29/watt by utilizing installation best practices. Researchers studied installation practices at 26 sites in the U.S. and Germany to determine current practices and future opportunities.
The Federal Aviation Administration (FAA) is updating its rules about siting solar projects at or near airport facilities. One key aspect of the new rules is guidelines about siting to avoid instances of glare, potentially dangerous reflections off of solar equipment.
