The National Renewable Energy Laboratory gauges the costs of combining residential solar with energy storage, as well as discusses current adoption barriers. Grid Impacts 16 Making Sense Of Solar: New Methods To Assess Penetration And Oversupply Risks Examining three operational variables can provide insight into the impacts of solar in major U.S. electricity markets. Resource Assessment 20 The Importance Of Accurate Performance Predictions 16 Several best practices can help developers reduce uncertainty in pre-construction solar resource assessments. Project Development 24 Developing Projects For Higher Education Colleges and universities have a growing appetite for on-campus solar projects, which require some unique development considerations. 24 20 ✹ Departments 6 Sun Dial 8 New & Noteworthy 10 Products & Technology 28 Projects & Contracts 32 Policy Watch 34 Sundown 4 Solar Industry b JUNE 2017 b_2_11.28_36_SI_1706.indd 4 5/26/17 10:55 AM 1 0 0 % L The easiest solar e mounting solution a for k Asphalt Shingle -P Roofs!
