Solar Schools: Powering classrooms, empowering communities.

Solar Schools from NRDC on Vimeo.

The Solar Schools platform will help parents and students connect and organize themselves around development of specific solar projects that increase renewable energy infrastructure in their community. We are building a bridge that connects local enthusiasm for renewable energy with the experts and resources they need to build the communities they desire.

4 Factors Driving the Marriage of Solar and Energy Storage

A solar-powered microgrid demonstrates the potential of coupling big batteries with commercial solar. What if you could finance the energy storage equipment, much the way solar panels are financed, and the batteries provided a revenue stream? Modern grid-scale battery systems are only put in place to save money or provide services to the grid. An example is one installation that includes 402 kilowatts’ worth of solar canopies in the parking lot and, in a twist that differentiates it from most commercial solar projects, a shipping-container-sized battery from startup Solar Grid Storage. Here in Knoxville we have a battery enhanced solar powered car-charging station located at the EPRI location off Dutchtown Road. On a daily basis, though, the battery will deliver frequency regulation services to the local wholesale grid. By providing quick bursts of power to keep a steady balance between supply and demand, battery owner Solar Grid Storage will earn money that is normally paid to natural gas power plant operators.

Here are the factors that are driving the combination of commercial solar and energy storage.

1. The technology is there. Better batteries are in development that will lower cost.

2. The economics can make sense. AES Energy Storage, for instance, provides frequency regulation services at a wind farm in West Virginia, buffered by a 32-megawatt lithium-ion battery bank. Revenue comes from reducing demand charges by using stored energy during peak hours. Most of its customers are in California, which has subsidies for distributed energy storage. By contrast, the desire to have emergency power has become a priority in East Coast states hit hard by Hurricane Sandy and other severe storms.

3. Solar installers want storage — if it pencils out. Military bases and island locations that rely on diesel generators are obvious candidates. A battery can smooth out the flow of power that panels provide to the local grid and address issues, such as the drops in voltage that come when clouds pass over. Batteries could also enable solar installations in places, such as farms, which would have required costly upgrades to the grid infrastructure. The contracts to finance a combined solar and storage system are complex and need to become more standardized, as power purchase agreements are, said president Scott Wiater of Standard Solar. Financing these types of systems is still relatively new and developers need to find customers willing to try not only solar, but also relatively new energy storage technology.

4. NRG Energy Inc. and Exelon Corp.’s Constellation unit say interest in combining solar power with battery storage has soared in the year since Hurricane Sandy knocked out power to millions of homes and businesses on the East Coast. They are among more than a dozen solar providers that have introduced or enhanced in the past year systems that combine rooftop solar panels that generate power and batteries that retain electricity to use later.
People with solar-powered homes and businesses were frustrated to discover that losing power from local utilities also knocked out the inverters that connect rooftop panels to the grid, leaving them unable to tap the electricity they were producing. Adding battery storage solves that problem, said Tom Doyle, chief executive officer of NRG’s solar unit.

It’s also a growing threat to utilities.
“When Sandy came along we really didn’t have a product to keep solar power flowing during blackouts,” Doyle said in an interview yesterday at the Solar Power International conference in Chicago. “Now we can install systems that continue operating when the grid fails, and the costs are coming down.”
Battery storage can add more than 20 percent to the cost of a typical 10-kilowatt solar system for a four-bedroom home, Brendon Quinlivan, director of solar development at Constellation, said in an interview.

Tennessee receives $5M for solar energy

Tennessee has received $5 million to support research and development of solar energy from the U.S. Department of Energy’s SunShot Initiative.
The funding is part of a $60 million investment in the initiative, which is designed to lower the cost of solar electricity, advance grid integration of solar energy systems and support the growth of the solar energy workforce in the country.
According to a DOE statement, the solar industry has created nearly 20,000 new jobs. An estimated 119,000 people are employed at 5,000 solar energy companies across the U.S. The funding will help provide training for engineers, utility workers and for students.

residential solar installations is stronger and broader than expected

Study Says Most Americans Would Consider Residential Solar. A study from research firm Market Strategies International finds that interest in residential solar installations is stronger and broader than expected among American consumers, even when those consumers are educated on associated costs. With few exceptions, this interest is strong across virtually all age and income groups.

Survey participants were informed that, “The cost of a typical home solar system is about $30,000 and provides about 60% of a home’s electricity needs. The final costs of a solar system can be reduced through a federal tax credit that allows purchasers to deduct 30% of the systems’ cost from their income taxes. Some states also provide financial incentives for solar installations.”

According to the survey, the information made 51% of respondents more interested in home solar systems, with consumers older than 55, again, the only group to show less interest. A majority of respondents across every income group continued to show interest – even low-income households with incomes under $25,000.

“It’s pretty clear that most utilities in the U.S. have to figure out an effective strategy for working with their customers who want solar power,” says Jack Lloyd, senior vice president of energy at Market Strategies. “Companies will take different approaches in adapting to the situation, but rooftop solar appears to be poised to move beyond its early adopter niche and become a more mainstream phenomenon.”

Start your 2013 ARiES Energy Solar Tour at Wampler’s

Most of our Solar Tour sites are available for visits throughout the month, but Wampler’s Farm Sausage is open to the public one day only – don’t miss your chance to learn and win!

Saturday, October 19 from 11am to 2pm at Wampler’s Farm Sausage 

 

We can’t think of a better way to start your tour of the future of distributed power than with Wampler’s Farm Sausage.

Wampler’s Farm Sausage, a sausage company in the foothills of the Appalachian Mountains, has been setting the pace and leading us towards energy independence and a cleaner, healthier future for the generations to come. Wampler’s started with a small 30-kilowatt (kW) solar PV system and leveraged that success into a 500 kW solar PV system. The confidence and success of these two investments have helped Wampler’s decision to install the world’s first Proton Power CHyP system!
 
Ted Wampler, Jr., President of Wampler’s Farm Sausage, will be on-site for the kick off of ARiES Energy’s 2013 Solar Tour. He will share with you about the company’s exciting, profitable journey to energy independence and a cleaner, safer future for your children.
