On November 2nd, TSEA will hold the 4th annual Solar Tour. One of the stops on the tour will be with Twin Willows Development off of Hardin Valley Rd, near Buttermilk Dr. The first house, installed with DOW’s solar shingles, will be explained by subdivision developer Adam Hutsell, and his installer, Jim Laborde. This will be a first for TVA, in which a developer will be installing solar as part of the overall construction of the homes at no extra cost. In addition to the solar, the energy saving features of the construction and choice of appliances tend to save energy, reducing the cost of monthly expenses. The tour will begin with an introductory talk at 8:30, at the Public Meeting room at Knoxville Transit Center on Church St(across the street to the Civic Center). We have limited seating, so arrive as soon as possible to ensure a place on our bus!

The Tennessee Valley Authority has recently developed a community solar initiative designed to add at least 500 kilowatts of solar energy for their utility and government properties.
TVA issued a request for proposals (RFP) on Aug. 15 to identify community members interested in participating in this Solar Aggregated Value and Education (SAVE) initiative.
This initiative will also provide an opportunity to test the market for the upfront purchase of Renewable Energy Credits, or RECS, that are directly tied to generation from a local solar facility. RECs represent the property rights to the environmental, social and non-power qualities of renewable electricity generation. RECs are sometimes purchased to meet legislative or regulatory mandates, meet internal goals, support environmental stewardship and other objectives.
The RFP will be handled through a two-stage application process. The submission deadline for the concept paper proposal will be in November 2013, with the full application due in February 2014 for those selected past the first stage. Final selection of participants is planned for April 2014.
The SAVE initiative is the first of 11 projects TVA is launching as part of a Clean Air Agreement with the U.S. Environmental Protection Agency that support TVA’s vision for low-cost and cleaner energy.
The innovative approach tries to provide renewable credits and tax breaks for industry, the chance for residents to promote more solar power and the opportunity for TVA to get more renewable power to comply with a 2-year-old settlement with the U.S. Environmental Protection Agency.
TVA began soliciting proposals under the new Solar Aggregated Value and Education (SAVE) program last month. Program director Neil Placer said TVA expects to have one or two solar projects added to its grid by 2015.

Solar Panels Growing Hazard for Firefighters – Why the Need for Integrated Converter with each panel
Firefighters battling the massive 11-alarm blaze at the Dietz & Watson distribution center in South Jersey faced an unlikely foe during the fight — solar panels.
A solar array with more than 7,000 photovoltaic panels lined the roof of the nearly 300,000 square-foot refrigeration facility which served as a temporary storage center for the company’s deli meats and cheeses. But the panels, while environmentally sustainable and cost-saving, may have led to the complete destruction of the warehouse.
Fighting the fire under bright blue skies Sunday, Delanco Fire Chief Ron Holt was forced to keep firefighters from attacking the blaze from the roof because of electrocution concerns.
“With all that power and energy up there, I can’t jeopardize a guy’s life for that,” said Holt. Those electrocution fears combined with concerns of a collapse forced firefighters to simply spray the building with water and foam from afar.
Ken Willette from the National Fire Protection Association, a nonprofit that develops standards for firefighting, says electrocution is one of the hazards firefighters are increasingly facing fighting blazes at structures where solar panels are deployed.
“Those panels, as long as there’s any kind of light present, whether it’s daylight or it’s electronic lamp light, will generate electricity,” he said.
A 2011 study from the Underwriters Laboratory found solar panels, being individual energy producers, could not be easily de-energized from a single point like other electric sources. Researchers recommended throwing a tarp over the panels to block light, but only if crews could safely get to the area.
SLevy: The issue is the series connection of many panels result in high voltages being developed which could be lethal if improperly handled. There are several answers but the one that makes the most sense to me is to modify the junction box in the back of each panel with an intelligent converter (either a DC-DC converter or a DC-AC inverter) that can disconnect itself from the string either from an internal sensor detecting a fault condition, like heat, or by the main disconnect for the solar system being activated so that all panels are isolated from each other. Then the danger is controlled and fire-persons can do their job and not worry about high voltage danger. A wireless remote monitor will verify the safe condition allowing firefighters to do their job in safety. The other benefit to the solar array owner is the same detection system will warn of panels being stolen. The cost of the intelligent converter should be 10% or less than the cost of the basic panel. Present fire safety regulations do not address this problem.
Legislation Expands U.S. Hydropower Production Which Will Benefit Pumped Storage and Solar Dispatchability
Legislation designed to expand hydropower production in the United States by improving and streamlining the licensing process for small hydropower projects is now law. “President Obama’s signature on hydropower legislation is terrific news for expanding renewable energy and creating jobs across the country,” said Voith Hydro President and CEO Kevin Frank.
The Hydropower Regulatory Efficiency Act will require FERC to examine a 2-year licensing process for non-powered dams and closed loop pump storage. TVA should give top priority to increasing their pumped storage using no longer active mine, coal washing stations and converting them to closed pumped storage facilities. First, these are environmentally damaged facilities that need attention. Second, by adding a surface reservoir to receive the water from the elevated tailing ponds, TVA could increase its pumped storage first with closed pumped storage, then modifying existing dams to create a lower pond below the dam receiving stream. According to one source at TVA the issue with increasing pumped storage is the objection on environmental grounds. The answer is to select those sites that would have the lowest environmental impact using groups like the Sierra Club to help with the selection and the environmental impact study.
We need to increase pumped storage for both renewables and for nuclear plants. TVA has 47 dams listed on their website. There is a good chance that some of these dams would lend themselves to pumped storage. That is where TVA should invest.
If anybody doubts that federal energy regulators are aware of the rapidly changing electricity landscape, they should talk to Jon Wellinghoff, chairman of the Federal Energy Regulatory Commission (FERC).
“Solar is growing so fast it is going to overtake everything,” Wellinghoff told GTM last week in a sideline conversation at the National Clean Energy Summit in Las Vegas.
If a single drop of water on the pitcher’s mound at Dodger Stadium is doubled every minute, Wellinghoff said, a person chained to the highest seat would be in danger of drowning in an hour.
“That’s what is happening in solar. It could double every two years,” he said.
Geothermal, wind, and other resources will supplement solar, Wellinghoff said. “But at its present growth rate, solar will overtake wind in about ten years. It is going to be the dominant player. Everybody’s roof is out there.” Advanced storage technologies also promise lower costs, he said. “Once it is more cost-effective to build solar with storage than to build a combustion turbine or wind for power at night, that is ‘game over.’ At that point, it will be all about consumer-driven markets.”
If FERC does not ensure the grid is ready to integrate the growing marketplace demand for distributed solar and other distributed resources, Wellinghoff said, “We are going to have problems with grid reliability and overall grid costs.”
Transmission infrastructure will be able to keep up with solar growth. The big changes will be at the distribution level where FERC has less influence, he explained. But the commission has been examining the costs and benefits of distributed generation (DG) in wholesale markets.
“Rate structures need to be formulated in ways that fully recognize the costs and benefits of distributed resources,” Wellinghoff said. “In many utility retail rates, a disproportionate amount of the fixed costs are recovered through a variable rate. That is problematic when a lot of people go to distributed generation.”
The net metering controversy this has caused at utilities like Xcel and Arizona Public Service, he said, can only be resolved by “the fully allocated, fully analyzed cost and benefit study of distributed resources.”
This blog is the result of many calls to TSEA regarding homeowners rights when their home owners associations prevent homes in their association from installing solar panels. The original article is thanks to the American Solar Energy Society (ASES) and their solar citizen newsletter. Join TSEA and ASES to create a strong ally in promoting solar in our state and in our country.
By Steve Wright
The benefits of residential solar panel arrays are becoming clearer with each passing year. Rooftop solar panels reduce energy expenditures, carbon emissions and infrastructure-related inefficiencies. There’s also mounting evidence that solar increases the value of the home. Unfortunately, homeowner associations across the country continue to ignore the overwhelmingly positive body of evidence and impose onerous restrictions on residential solar panel installations. Read on to learn how to fight back.
Rights of the HOA
Well-established legal precedents support efforts by HOAs to impose “reasonable restrictions” on their members’ attempts to install solar panels. Generally speaking, courts have been reticent to overturn specific HOA bylaws unless they are found to be arbitrary, unconstitutional or blatantly illegal.
Because an outright ban might look arbitrary (or illegal in many states), HOAs often make rules that restrict the visibility and size of solar panel arrays. Ostensibly designed to promote health and “peace of mind” by reducing glare and rendering “eyesores” less visible, these restrictions often compel homeowners to move their panels to shady, fenced-in yards or to first-floor roofs that can’t be seen from the road.
Unfortunately, HOAs can also use certain legal caveats to deny solar panel installation outright. These often take the form of restrictive covenants designed to preserve or increase property values. They may purport to preserve a community’s “brand” by standardizing the appearance of its homes. Unlike restrictive covenants that come with “sunset clauses” or “express termination” windows, bylaws that restrict solar panel use tend to be permanent and must be invalidated by legal challenges or law changes.
Solar Access Laws
With this in mind, several states have enacted common-sense legal protections for homeowners who want to go solar. While these generally don’t interfere with the “reasonable restrictions” guideline, they prevent persnickety HOAs from making punitive demands on well-meaning members.
California’s Solar Rights Act serves as the model for most of these state laws. Although it was originally intended to prevent HOAs from imposing arbitrary restrictions or outright bans on solar panel arrays, it has since been expanded to cover municipal and regional government bodies. The law has also been amended to ensure that homeowners retain access to state-sponsored solar energy grants and to protect inhabitants of multi-unit dwellings like high-rise apartments and condominiums.
Florida’s own Solar Rights Law offers similar protections. Without interfering with the commonly accepted “reasonable restrictions” allowance, the law prohibits HOAs from banning solar panel arrays and specifically overrides any HOA bylaws that curtail the installation of rooftop solar panels. In other words, Florida homeowners can use most or all of their roofs’ square footage to install arrays.
Even wintry Massachusetts has gotten in on the action. The state’s Solar Access Law nullifies existing and future HOA prohibitions and expressly permits solar easements on residential land. Even better, it prohibits HOAs from restricting the trimming and clearing of vegetation that obscures solar panels on members’ properties.
Remedies for Homeowners
Most homeowners start by attempting to persuade their HOA to refrain from unreasonable restrictions on solar panel installation. This requires an age-old persuasion tactic: the power of credibility. Homeowners often point to credible sources that support the efficacy of solar power. They might cite the U.S. Energy Department’s estimate that a single 10,000 square-mile patch of the Nevada desert receives enough sunlight to satisfy the entire country’s energy needs, or multiple studies that have found a positive correlation between residential solar panel arrays and home values.
Such persuasive efforts must focus on the positive aspects of solar power and cite concrete evidence from non-controversial sources. You could argue that solar panels would reduce homeowner electricity bills and the frequency of peak-period blackouts. Use a politically-neutral source for your facts — the U.S. Department of Energy has a website rich with good data. It’s hard to argue with concrete evidence.
If these efforts prove insufficient, homeowners generally attempt to negotiate a compromise agreement. Since aesthetic concerns often drive these restrictive covenants, successful agreements may require homeowners to keep front-facing portions of their roofs free of solar panels. As a compromise, HOAs might allow solar panel users to trim trees that shade these arrays. Magnanimous homeowners might even volunteer to divert a portion of their panels’ production to commonly held equipment like public-area sprinkler systems or streetlights.
In the worst case, a homeowner may be forced to take legal action against a stubborn HOA. Pro-solar organizations advise homeowners who pursue this course of action to focus on HOA-initiated actions that a court might find to be arbitrary, punitive or “unreasonable.” Ultimately, litigants must be prepared to cite facts that refute common arguments about negative home-value and aesthetic impacts. Those who wish to pursue legislative remedies often use stronger solar-rights laws, like those in Massachusetts and Florida, as templates.
Despite widespread legal protections for homeowners, many HOAs go to great lengths to restrict members’ rights to install solar panel arrays on private property. In a world beset by rising fossil-fuel energy costs, weakening electric infrastructure and a deteriorating natural environment, tension between an HOA and its members is counterproductive. Fortunately, commonsense legislation and a growing body of pro-solar legal precedents have made it easier for homeowners to fight back against overzealous HOAs.

TVA will install at least 500 kWs of solar PV at TVA facilities, TVA directly served customer locations, or another government-owned facility (including all local public power companies served by TVA), and shall maintain the PV installations for a minimum of twenty years following approval of project plan. The objective of SAVE is for TVA to partner with the regional community to raise solar energy awareness and education, reduce solar energy costs, and to test the market for upfront Renewable Energy Credit (REC) purchases. The SAVE initiative is based on a community solar business model which brings together individual donors, organizations, and investors to leverage community engagement and maximize stakeholder value.
