Part of the future of solar energy, especially for residential use, may be small “community-based” systems in which neighbors join together in the construction and use of solar systems to optimize the energy produced in their neighborhood – and share in the benefits.

New research by engineers at Oregon State University indicate that an optimal development of neighborhood solar energy might increase the total electricity produced by 5-10 percent, a significant gain by the standards of solar energy efficiency. At the same time, it can reduce the variability and unpredictability of the solar resource. Read more here.

Rooftop Solar Panels Could Power Nearly 40 Percent Of the U.S., by Mary Beth Griggs, Popular Science. The Energy Department’s National Renewable Energy Laboratory (NREL) issued a report last week that analyzed the ability of America’s roofs to host solar panels. They looked at rooftops in 128 cities across the country, analyzing buildings large and small for their suitability for hosting photovoltaic (PV) solar panels, and how much power could be generated in each location. The estimates varied by state and by region, but overall, the report found that 39 percent of the country’s energy could be generated by rooftop solar panels.

Experts Explore Global Role of Solar PV, Solar Industry Magazine. The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) says its scientists, along with their counterparts from solar energy research institutes in Germany and Japan, gathered recently to discuss the future of photovoltaics and assess its contributions to increasing global prosperity, energy security and mitigation of climate change.

Detroit council approves 10-acre solar energy plant on vacant city-owned land, by Joe Guillen, Detroit Free Press. Members of Mayor Mike Duggan’s administration described the project as a catalyst to enhance the neighborhood, along with concurrent plans to use federal funds for nearby blight demolition and a commitment to train residents for “green collar” jobs focused on the reuse of vacant land.

Officials To Flip Switch On 100-Acre Solar Plant in South Arkansas, UALR Public Radio. The switch will soon be flipped on 151,200 solar panels that will provide electricity to the growing defense industry operations in East Camden. The 12-megawatt solar field will generate electricity equivalent to powering 2,400 homes.

Study: Home values increase when solar panels get installed, by Kelsey Ramirez, Housingwire
A new study from The Appraisal Journal, the academic publication of one of the nation’s largest association of appraisers, shows that homes that use solar panels are sold at a premium.

As the industry debates the role of the utility in a distributed energy future, utility leaders are touting a network approach, by Krysti Shallenberger, Utility Dive

It’s no big secret: The utility sector is undergoing a transformation, and new disruptive and distributed technologies are increasingly driving that change.  “We’re witnessing a convergence of old and new technologies,” Bob Stump, an Arizona utility regulator, said in a speech at Edison Electric Institute’s annual Powering the People event. “Distributed resources in some way or another are here to stay.” The majority of utility executives surveyed by Utility Dive
acknowledge the utility business model needs to change and is indeed changing, with only 5% of those surveyed saying their utility should not build a business model for distributed energy resources. Continue reading.

This new transmission line will help unleash wind energy in the Great Plains

Wind and sunlight have many advantages as fuel sources, but one big drawback is that they aren’t portable. You can’t carry them to a power plant. You have to build the power plant wherever you find them.

That puts the US in an awkward situation, because the most intense wind and sunlight tend to be found in remote, low-population areas — think the sunny desert Southwest or the windy Great Plains.

In states implementing additional charges, net metering caps & other regulatory changes: “Can storage rescue solar?”

By Todd Olinsky-Paul, Clean Energy Group

Todd Olinsky-Paul postIn addition to benefiting customers: From the utility perspective, behind the meter storage should be viewed as an opportunity as well. After all, the more storage is paired with solar, the more control we will have over solar’s variable output, which is the main issue utilities cite for limiting the amount of solar on their networks (a potential $2 billion in lost revenue to conventional generators from rooftop solar is rarely mentioned). The more forward-looking utilities are even investing in small behind-the-meter storage systems at customer sites, which they can use to provide grid services and cut costs, while providing resilient power and other services to the host.

Unfortunately, the majority of utilities seem to be either neutral or negative on the question of distributed energy resources in general, and solar in particular. As Rocky Mountain Institute predicted more than a year ago, the more utilities try to decrease incentives and add fees for solar customers, the more incentive these customers will have to invest in storage, as a way to protect the value of their solar investment and further reduce their reliance on grid-purchased electricity.

A new technical study that is more detailed and extensive than previously achieved, the US Energy Department’s National Renewable Energy Laboratory (NREL) has significantly increased the potential for US building rooftops to generate electricity from solar PV (photovoltaics) systems.

The analysis within the report entitled “Rooftop Solar Photovoltaic Technical Potential in the United States: A Detailed Assessment,” used detailed light detection and ranging (LiDAR) data for 128 US cities across the country, along with improved data analysis methods and simulation tools, to update and make more accurate estimates of technical potential of PV on rooftops at the national, state, and zip code level. Read more.

Download the NREL Report.
The report states that the technical potential of 1,118GW of capacity and 1,432TWh of annual energy generation was possible, equivalent to 39% of current US electricity sales. This is almost double (664GW – 800 TWh) the previous analysis undertaken and reported in 2008.

Clean Energy Utah and U Community Solar are offering a discount on solar panels to all university students, faculty, staff and alumni from March 15 through Sept. 30, 2016. Clayton Johnson, clean energy project coordinator for Utah Clean Energy said they have a simple goal. “We want to empower more Utah families with clean solar energy on their homes,” Johnson said. In 2014, U Community Solar (UCS) provided panel installation to almost 400 households. Johnson said the program would save a combined $7.7 million over the next 25 years. The continued effort is to prevent over 100 million pounds of carbon dioxide emissions. Continue reading.

#DoTheMath: How Rooftop Solar Will Save Us Billions

By Sean Gallagher, Solar Energy Industries Association (SEIA) Blog
SEIA
When we do the math, the increase in electricity supply provided by distributed solar generation and its associated reduction in demand trickles down to all ratepayers, in at least two ways. First, grid operators buy less power, reducing their costs. Second, reduced net demand leads to a reduction in wholesale market prices, further reducing grid operators’ costs.  Both streams of reduced costs are passed through to local utilities, which then result in reduced retail prices for ratepayers.

Remember this the next time your local utility tells you that your neighbor with solar is “shifting costs” onto the system. The fact is that the system is transforming, and that is good for us all.

Rocky Mountain Institute (RMI) Manager Joseph Goodman left a position in the U.S. Department of Energy (DOE) SunShot program for the opportunity to show how to make community solar markets happen, he told Utility Dive in an interview.

Under Goodman’s leadership, RMI is now working with community-based organizations, rural electric cooperatives and public and investor-owned utilities to demonstrate that it is possible to deploy community solar installations at prices up to 40% lower than installations today.
