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.”

Japan Next-Generation Farmers Cultivate Crops and Solar Energy

Farmers in Japan can now generate solar electricity while growing crops on the same farmland. This co-existence or double-generation is known as “Solar Sharing” in Japan. The concept was originally developed by Akira Nagashima in 2004, who was a retired agricultural machinery engineer who later studied biology and learned the “light saturation point.” The rate of photosynthesis increases as the irradiance level is increased; however at one point, any further increase in the amount of light that strikes the plant does not cause any increase to the rate of photosynthesis.

By knowing that too much sun won’t help further growth of plants, Nagashima came up with the idea to combine PV systems and farming. He devised and originally patented special structure, which is much like a pergola in a garden. He created a couple of testing fields with different shading rates and different crops. The structures he created are made of pipes and rows of PV panels, which are arranged with certain intervals to allow enough sunlight to hit the ground for photosynthesis.

Based on the tests conducted at his solar testing sites in Chiba Prefecture, he recommends about 32% shading rate for a farmland space to reach adequate growth of crops. In other words, there is twice as much empty space for each PV module installed. Takazawa installed 348 PV panels on a small 750 square-meter of farmland. PV panels are installed on pipes, which are 3-meter high from the ground. Rows of PV panels are installed every 5 meters. Under the PV system, Takasawa’s father has been cultivating peanuts, yams, eggplants, cucumbers, tomatoes, and taros and will cultivate cabbages during the winter. These vegetables are sold at a nearby street and consumed by his neighbors.

Many have questioned stability and durability of the PV structure for solar shared family. Nagashima stated that his systems, which are made of thin pipes without concrete footings, even withstood strong winds and earthquakes during the Fukushima Tsunami disasters in 2011. These systems are extremely lightweight and installation of PV panels are spaced out, allowing air to flow through between the panels. This will eliminate concern that the panels will receive wind load and be blown away, therefore, reducing the need for complicated and expensive mounting hardware.

Leading Utilities Recognize the Need for Solar Energy as Older Nuclear Plants Pass Their Economic Viability

CEOs from opposite sides of the country also spent much time discussing the increasing role of renewable energy and distributed generation.

California is known for having the nation’s most ambitious renewable energy mandate while North Carolina, where Duke is based, also has a growing solar energy presence.
Edison CEO Ted Craver said electric utilities would be mistaken to dismiss distributed generation as merely a “fringe” business in the future. The Edison chief said his company initially started in the field by supplying big solar arrays for “big box” stores.

“A lot of this is really experimental,” Craver said. Utility subsidiary Southern California Edison (SCE) used to rely on industrial customers for one-third of its load but that is now probably closer to 10 percent, Craver said.

While some argue that California policy has been inhospitable to heavy industry, it’s important to realize that manufacturers are looking to generate more of their own power, Craver said.
The utility, SCE, is also investing more in the transmission side of its business to accommodate the growing role of distributed generation in California.

Duke is developing a variety of resources in its service territories — including new combined-cycle and peaking units in Florida — to help compensate for retirement of the Crystal River nuclear plant and potential coal units retirements as well. California is known for having the nation’s most ambitious renewable energy mandate while North Carolina, where Duke is based, also has a growing solar energy presence.

TVA forms advisory energy panels

The Tennessee Valley Authority is forming two new advisory boards this fall to give advice and counsel about the changing power market ahead.

TVA is creating a new 19-member panel known as the Regional Energy Resource Council to offer ongoing input into how TVA balances the need for reliable power and low-cost electricity with energy efficiency, cleaner energy and transmission requirements. Joe Hoagland, chief technology officer for TVA, said the new council “will provide valuable advice as TVA develops policies and strategies associated with our future.” “TVA wants to ensue that it manages the power system with all public interests in mind,” Hoagland said.

The new Regional Energy Resource Council is headed by Goodrich “Gus” Rogers, the president of the Jackson County Economic Development Authority in Alabama. Rogers is an ardent supporter of finishing the incomplete Bellefonte Nuclear Power Plant his Hollywood, Ala., which TVA will consider in is long-range power plan. But other members of the 19-member panel approved by the TVA board have differing views.

TVA spokesman Scott Brooks said TVA also will soon form an advisory board to help guide its Integrated Resource Plan, which is a 10-year plan for future power growth in the Valley.

Photovoltaic System Pricing Updated 2013

The following is an extract from a recent study by Lawrence Berkeley National Labs and National Renewable Energy Laboratory. The report is a high-level overview of historical, recent, and projected near-term PV system pricing trends in the United States, drawing on several ongoing research activities at LBNL and NREL. Prices are subject to the location, suppliers, pricing, as well as local economic factors. According to the report near future analysts expect system prices to continue to fall, but for module prices to stabilize (Module ASP projected to be between $0.50/W – $0.75/W by 2014 ).

Modeled overnight capital cost for systems quoted in Q4 2012 (expected to be installed in 2013):

Residential (5.1 kW) was $3.69/W, a reduction of 13% from Q4 2011

Commercial (222.5 kW) was $2.61/W, a reduction of 19% from Q4 2011

Utility-scale (192.8 MW) was $1.92/W, a reduction of 23% from Q4 2011.

DOW Solar Powerhouse Shingle

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!

TVA launches community solar initiative

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.
