After two and a half years of talking to people about solar energy, the Solar Hartland Renewable Energy project is moving on to new efforts.

We have talked with well over a thousand people at booths, presentations, and site visits, enticing people with solar powered smoothies and information. 
We've also counseled several businesses about fitting solar power into their plans, developed tools for site assessment and feasibility studies, held educational presentations, and worked towards making community solar a reality.

-Information about the solar powered smoothie blender can be found on the solar blender page at www.transitiontownhartland.org 
-A community solar presentation from July 2012 can be downloaded at the bottom of this page.  Some of the information, such as tax incentives and third party leasing has changed, but it is still a good overview.
-Our last solar site evaluation form can be downloaded at the bottom of this page- but please note that the financial calculations on the last page are not up to date.  The prices of solar equipment have been constantly changing, and the most accurate pricing will be from the dealer who is providing a system.  It is still useful for evaluating a site, and sizing a PV array.
-A list of dealers in Vermont can be found at http://www.revermont.org/main/  and up to date listings of incentives can be found at www.dsireusa.org 

My current project is Solar Electric Cargo Bicycles.
This bike uses a 500 watt geared motor with a 720 watt hour LiFePO4 battery, providing a 65 mile range with light pedaling.  It uses about 0.02 kWh, (costing about a quarter of a penny), of electricity per mile.  The solar panels provide 60 watts or about 25% of the energy needed, extending the range and providing remote charging while parked away from an outlet.  Three more projects are planned- a longtail with a direct drive motor, a trike with a box in front, and a semi enclosed recumbent with a solar panel on the roof.

I have been lucky to have worked with many wonderful people on many projects over the years, but because the people in the groups have changed, I will be starting a new site at:

The second bike, a Longtail with a direct drive hub motor, at the top of
Mt Washington, September 13, 2014.

The third bike, a mid cargo, mid drive is now being built.

Details of the cargo bikes will be posted there.  I will still be available for general questions about solar energy and design, more in depth consultations, modeling systems using separate calculations or the NREL System Advisor Model, and will still do free site assessments in the Hartland, VT area as a volunteer for the town energy committee.   For more information please send me an email at kkemvt@gmail.com
