Ford develops solar powered car for everyday use

Ford has developed a concept model that runs primarily on solar power, which could bring the world one step closer to having a vehicle for everyday driving that is not dependent on traditional energy sources.

The C-MAX Solar Energi Concept is a collaboration between Ford, SunPower Corp. and the Georgia Institute of Technology. The concept car is expected to be unveiled next week at the Consumer Electronics Show in Las Vegas.

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.

What’s the Story of Snow Covered Panels

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.
