2016 is a breakthrough year for solar
By Rona Fried, contributor
Over the past few months, we’ve seen a rush of exciting developments in solar, some giving us insight into how distributed energy may work in the future.
Thanks to tax credits (ITC) being renewed, 2016 will be a breakthrough year for U.S. solar, rising a stunning 119 percent. Sixteen gigawatts (GW) are expected to be installed, shattering last year’s record 7.3 GW, according to the Solar Energy Industries Association (SEIA) and GTM Research. In February, we passed a wonderful milestone as the millionth home was outfitted with a solar system. About 300,000 Americans will install solar this year.
Sixty of the world’s largest corporations have joined the Renewable Energy Buyers Alliance (REBA), to make it easier for companies to buy renewable energy directly from utilities. Right now, it’s complicated: They either have to negotiate separately with utilities to get the amount of energy they need or sign long-term power purchase agreements with developers. Smaller companies don’t use enough electricity to participate. The alliance is challenging utilities to add 60 GW by 2025.In more great news, 17 states joined the “Governors’ Accord for a New Energy Future” to make a clean energy future a reality. Governors say they will establish goals and benchmarks to accelerate energy efficiency and renewables, modernize the grid, and incentivize clean transportation.
Signatories represent 40 percent of U.S. population: Hawaii, California, Oregon, Washington, Nevada, Iowa, Minnesota, Michigan, Pennsylvania, Virginia, Delaware, New York, Connecticut, Massachusetts, Rhode Island, New Hampshire and Vermont.
And the International Solar Alliance held its first meeting. The goal is to mobilize $1 trillion for “massive deployment of affordable solar energy by 2030.” One-hundred-and-twenty countries have signed up!
Community solar is expected to take off in 2016, and a trade association has formed to push this wildly popular option, the Coalition for Community Solar Access. These shared arrays always quickly sell out because half of Americans either rent or don’t have enough sun on their roof for solar.
One of the innovative uses of community solar is in Minnesota, where the Rural Renewable Energy Alliance (RREAL) is providing solar electricity in lieu of cash for energy assistance. Xcel Energy, a utility, plans to double the amount of solar on its Minnesota grid by giving customers the option of participating in community solar projects.
Innovative new models appear
You have too much shade on your roof for solar panels, but your neighbors have plenty of sun, producing more than they need. Why not buy electricity from their solar arrays instead of from the grid? That’s what is happening in Brooklyn, N.Y. and soon, in Boston. It runs on Ethereum, a technology created for secure Bitcoin transactions — it monitors energy flows through the system and allows residents to buy and sell energy through the peer-to-peer network.
Arizona’s largest utility, Arizona Public Service (APS), is testing advanced solar inverters to operate rooftop solar systems remotely, turning them into “power plants.” It allows APS to either ramp up or curtail electricity flows into the grid based on customers’ real-time energy needs.
“Energy used to flow in one direction, from our power plants to a customer’s home or business. That is no longer true today,” says Scott Bordenkircher, director of technology Innovation at APS.
