"No roof, no Solar power. That has been the dispiriting equation shutting out roughly half of all Americans from plugging into the sun," writes the Washington Post's "Climate Coach" column. "But signing up for solar soon might be as easy as subscribing to Netflix." Scores of new small solar farms that sell clean, local electricity directly to customers are popping up. The setup, dubbed "community solar," is designed to bring solar power to people who don't own their own homes or can't install panels — often at prices below retail electricity rates... At least 22 states have passed legislation encouraging independent community solar projects, but developers are just beginning to expand. Most existing projects are booked. At the moment, community solar projects in the United States generate enough electricity to power about 918,000 homes — less than 1 percent of total households, according to the Solar Energy Industries Association, a nonprofit trade group. But as more states join, and the Environmental Protection Agency's "Solar for All" program pours billions into federal solar power grants, more Americans will get the chance... While projects exist in most states, they are highly concentrated: More than half are in Massachusetts, Minnesota and New York. These might be on a condo roof, or on open land like the 10-MW Fresno community solar farm, on a city-owned plot surrounded by agricultural land. Most are small: 2 megawatts of capacity on average, about enough to power 200 to 400 homes... The renewable energy marketplace EnergySage and the nonprofit Solar United Neighbors connect customers to community solar projects in their region. People generally receive monthly credits for electricity produced by their share of solar panels. These are subtracted from their total electricity bill or credited on future bills... Subscribers on average save about 10 percent on their utility bill (the range is 5 percent to 15 percent). These economics are propelling the industry to record heights. Between 2016 and 2019, community solar capacity more than quadrupled to 1.4 gigawatts. By the end of this year, energy research firm Wood Mackenzie estimates, there will be 6 GW of community solar. And the Energy Department wants to see community solar reach 5 million households by 2025. "The economics are strongly on the side of doing this," says Dan Kammen, an energy professor at the University of California at Berkeley. "It's now cheaper to build new solar than to operate old fossil [fuel plants]. ... We're at the takeoff point." The article notes "solar for renters" saves about $100 per year for the average ratepayer (while rooftop solar arrays may save homeowners over $1,000 annually). But according to the article, the arrangement still "reflects a new reality... "Solar energy prices are falling as private and public money, and new laws, are fueling a massive expansion of small-scale community solar projects."
