Local objections to proposed solar photovoltaic (PV) installations sometimes include concerns that the modules will cause glare that could impact neighbors or aviation. Research on this subject demonstrates that PV modules exhibit less glare than windows and water. Continue reading

Community Solar: Lifting the Energy Burden on Low-Income Households

State energy offices, such as the CEO, are exploring approaches to reduce energy burden across the U.S. NREL’s Solar Technical Assistance Team worked with the CEO to evaluate their innovative approach: a low-income community solar program.
