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.

By the end of 2014, the United States had 20,500 megawatts (MW) of cumulative solar electric capacity, enough to power four million average U.S. homes. This success is the outcome of federal, state and local programs that are working in concert to make solar power accessible to more Americans.
This list includes important trends regarding North America's clean energy RFPs in 2014.
Solar energy within the built environment may be an overlooked opportunity for meeting sustainable energy needs in places with land and environmental constraints.
This study investigates how economically motivated customers will use energy storage for demand charge reduction, as well as how this changes in the presence of on-site photovoltaic power generation, to investigate the possible effects of incentivizing increased quantities of behind-the-meter storage.
U.S. Solar Market Insight™ is a collaboration between the Solar Energy Industries Association® (SEIA®) and GTM Research that brings high-quality, solar-specific analysis and forecasts to industry professionals in the form of quarterly and annual reports. Released December 9, 2014.
In this report, Rocky Mountain Institute (RMI), with support from the U.S. Department of Energy’s SunShot Initiative, investigates opportunities to optimize and demonstrate DPV’s value as it is integrated into the grid to utilities, customers, and solar companies alike.
Business leaders in America’s brightest, most competitive companies are increasingly choosing to install solar energy systems at their facilities. For the third year in a row, not only are more businesses choosing solar, but those that have used solar in the past are doing so again and again on rooftops across America. Walmart, Kohl’s, Costco, Apple, IKEA and more have all embraced solar energy. Collectively, the companies with the most solar capacity in the U.S. now have 1,110 systems totaling 569 megawatts (MW), generating enough electricity to power more than 115,000 homes.
179 million people in 33 states and Puerto Rico live within 20 miles of at least one of the 1,110 commercial solar installations that were analyzed in the Solar Means Business report. Expore photos of the installations at corporate retail sites, factories and data centers
