A One Megawatt Project Planned for Oak Ridge

Restoration SevicesRestoration Services Inc. is partnering with Vis Solis to build a one megawatt solar farm at the East Tennessee Technology Park, former K-25 site, on a site leased from Community Reuse Organization of East Tennessee (CROET). The solar power generated electricity will go to the TVA grid to run the equivalent of nearly 150 homes. Gil Hough, manager of the renewable energy division of Restoration Services says that is almost a done deal. Construction is expected to start in April. What makes this solar installation unique is the use of Vis Solis tracking of the sun to always keep the panels pointed towards the sun for maximum performance. The increase in power production can be as high as 30% over the conventional fixed arrays.

Every Four Minutes, Another American Home or Business Goes Solar

Obama_in_Georgetown-200x150This was the quote from the President’s State of the Union address this past week. He then suggested, as he has before, that we divert tax breaks from fossil fuel industries to fund more development of “fuels of the future.” Even Forbes stated that the shift in supports “While that policy makes some sense, it needs to be pegged to commodity prices..” There has been a split in the Republican Congress members from a solid wall against renewables, to one where many of the party are now supporting wind, solar and biomass. Expect the final version of the Agriculture bill to contain substantial support for biomass as an energy source. We do need more research into future solar development. We need to concentrate on supporting increases in conversion efficiency for solar PV.

We need the Federal Government to fund a more automated solar foundry in the Gigawatt class which would demonstrate producing solar panels for less than $0.30 per watt. We need to automate the installation of racking and solar panel mounting for solar plants. We have produced panels with 30% and higher efficiencies, but the cost was prohibitive. Focussing on higher efficiency along with a massive production facility will result in lower panel cost in large scale manufacturing. The windpower from Texas can be sent to TVA region for about four cents per kilowatt-hour according to recent testimony before the TVA resources council. Solar has to aim for that same price.

Installers and Solar Distributors Having Products for Farming Applications Should Attend No-Till Day

Milan No till field day
Visitors from around the world come to Milan on the fourth Thursday in July to learn the latest about no-tillage crop production techniques. In 2012, attendance at this event included 2,748 visitors from 65 Tennessee counties, 21 states (AL, AR, DE, GA, IL, IN, IA, KS, KY, LA, MI, MN, MS, MO, NE, NC, OK, SC, TN, TX, VA), and three international countries (Brazil, Lesotho and Mozambique). If you are interested in participating in their exhibition area, please contact me (Steve at 865-074-9218). If I do not answer, leave a message with your name, company, phone number and email address. I will respond via email with more information. They have an extensive industry/educational trade show and I will give you details.

LightWave Solar offers a Portable Solar Power Bank that uses the sun’s power where and when it’s needed most: power outages, farm maintenance, camping, tailgating, trade shows, etc.

The solar power bank charges quickly and can provide enough electricity for hours of lighting, refrigeration, fans, cell phone/laptop charging, entertainment systems, small power tools and more.

The solar power bank retails for $3,960 and is eligible for a 30% tax credit, bringing the cost of the unit down to $2,772. In addition, existing LightWave Solar customers receive a 10% discount!

Biggest Cost Reduction for Rooftop Solar Installations

According to a recent time-and-motion study of rooftop solar installations, the biggest opportunity for cost reductions are with integrated racking, and in eliminating the array of little nuts, bolts, wires, clips, pieces and parts that don’t add any functional value to the system, but still need to be assembled on the rooftop.

Will Rural America Continue REAPing Renewable Energy Rewards?

Barn_Caldwell_Idaho
Based on a tally of 2013 REAP announcements, the total awards for the Southeastern states approaches $5 million in grants, leveraging more than $15 million in private dollars. These investments include solar photovoltaic installations, energy efficiency equipment, geothermal, and biomass projects.
Energy efficiency awards were particularly notable this year, with diverse projects including irrigation, lighting, agricultural curing and drying, and diesel engines being replaced with electric motors.

Here’s the state-by-state breakdown of 2013 REAP grant awards for our region (rounded down to the nearest thousand):
FL > $354,000
GA > $1,400,000
NC > $1,417,000
SC > $584,000
TN > $1,224,000

Obama Commits U.S. Federal Government To 20% Renewable Energy Target By 2020

Obama_in_Georgetown
President Barack Obama has issued a presidential memorandum directing the U.S. federal government to pursue a goal of deriving 20% of its energy from renewable sources by 2020. The document also instructs all federal agencies to take specific steps to better manage building performance, enhance energy efficiency and reduce energy waste.

The missive represents a follow-through on the president’s plan to counter climate change, announced in June. It directs agencies to achieve the renewable energy consumption target through a number of approved actions. The actions, in order of priority, are the following:

Installing agency-funded renewable energy on-site at federal facilities and retain renewable energy certificates;
Contracting for energy that includes the installation of a renewable energy project on-site at a federal facility or off-site and the retention of renewable energy certificates for the term of the contract;
Purchasing electricity and corresponding renewable energy certificates; and
Purchasing renewable energy certificates.
The memorandum sets a number of interim targets for renewable energy usage up to the ultimate 20% by 2020 goal. The first of these is a 10% target for 2015.

Franklin will add second solar panel array

Franklin will lease unused land to a Nashville-based company for the future installation of a new solar panel array.

Energy Source Partners is proposing to spend $2.6 million to build a new solar array on a 3-acre sludge field site near Mack Hatcher Parkway. That array is expected to generate 1 megawatt of electricity, which would be sold to the Tennessee Valley Authority.

Over the course of the proposed 20-year contract, the 1 megawatt panels would generate $165,000 for Franklin by the 10th year of the program and about $800,000 from years 10 to 20.

Last year, Franklin leased part of an empty sludge field near its sewer plant off Claude Yates Drive to Nashville-based Energy Source Partners, which paid about $1 million to install 940 solar panels on the land. Those panels, which generate about 200 kilowatts, capture sun rays and convert them to electricity, which is then resold.

KKR and Google to Invest in Six U.S. Solar Power Plants

KKR & Co. and Google Inc. have struck a pact to invest about $400 million in six solar-power plants being built by Recurrent Energy LLC in California and Arizona. Development of the plants has been under way for years and they are expected to go online and begin producing power in January, the people said.

The plants—five in southern California and one in Arizona—are designed to produce about 106 megawatts of electricity combined, or enough to power about 17,000 U.S. homes, they said. San Francisco-based Recurrent, which will continue as their operator, has struck long-term power supply agreements with three buyers for the electricity they’re expected to churn, the people said.
