Pew Charitable Trust has a division on Clean Energy led by Phyllis Catano. At the end of this past year Pew gave their clean energy report in the form of a webinar including published presentations by three top tier organizations represented by representatives including Phyllis Cuttino, director, Pew clean energy program, Pat Bousliman of Elmendorf Ryan, Ethan Zindler of Bloomberg New Energy Finance.

Installers and Solar Distributors Having Products for Farming Applications Should Attend No-Till 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.
Assume you live in the upper reaches of Minnesota and you are told that solar panels won’t work in cold, snowy climates. Wrong!! Yes, admittedly you have to do some clearing of snow off your panels but there are some preventive measures you can take to keep the solar power production at its peak. First, realize that though the sun’s rays are not as strong in the winter as during the summer; the sun does not rise as high. But the colder temperatures increase the efficiency of the panels that help boost the output power of the system. With that in mind, here are some tips for improving the power delivery of your system:
1. Bounce a tennis ball off snow-covered panels.
Homeowners who have rooftop solar panels installed can surprisingly increase the energy output by bouncing a tennis ball off the snow-covered panels. The small divots created by the tennis ball help begin the snow shed process and allow sunlight to reach the modules and begin converting energy.
2. Install solar panels at the largest angle possible.
A higher angle lessens the accumulation of snow on top of the panel. Everyone that is in a very snowy place, like in northern Michigan, should be aggressive in your tilting angle. So if you have a decision to make between something like 30 degrees or 40 degrees, it’s better to go 40 degrees.
3. Don’t set up panels in a way that allows snow to gather at the bottom.
Installing panels in a way that allows the snow to fall freely from the array greatly reduces the impact of snow. When snow slides off the panel at an angle and gathers at the bottom of the module, the losses can significant. In those cases, when you have a very low tilt angle and a dam [of snow], you can lose all of the solar energy associated with the winter.
This is a request for proposal due January 10th. For details go to: http://www.cityofknoxville.org/purchasing/
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!
In what is being called an unprecedented decision, solar energy went head-to-head with natural gas in a competitive evaluation for utility resource planning — and solar came out on top.
Xcel Energy demonstrated need for 150 MW of new electricity generation by 2017 (and possibly 500 MW by 2019. Office of Administrative Hearings (ALJ) to look at several proposals to decide “the most reasonable and prudent strategy” to meet Xcel’s needs. Three of the five proposals received dealt with natural gas as the energy source, one offered solar in a rather unique way.
The solar project encompasses roughly 20 different commercial-sized sites (2-10 MW) adding up to 100 MW, sized to offset roughly 20 percent of the existing load at each respective substation. The cost for the 100 MW project was $250 million. Using computer models, the ALJ’s administrative law judge Eric Lipman compared each proposal against each other, gauging cost savings, fuel consumption, pollutants emitted, and other factors, and then added a number of contingencies for mandated CO2 reductions, market pricing fluctuations for each energy source, and both short- and long-term demand projections — as well as the mandated RPS and solar carve-out. Lipman also added criteria to be “compatible with protecting the natural and socioeconomic environments, including human health.”
Lipman decreed that in the short-term “the greatest value to Minnesota and Xcel’s ratepayers is drawn from selecting Geronimo’s solar energy proposal.” When properly analyzed under either a LCOE or strategist modeling, the solar submission was the lowest cost resource proposed.
Responding to the ruling, Xcel issued a statement saying it appreciates the work of the ALJ toward resource acquisitions but it “disagree[s] with some of the findings and recommendation,” and the company pledged to file a complete response once exceptions are filed with the commission.
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.
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
