MRES Solar Tour 2011 logo

Minneapolis – The free, self-guided 16th Annual MRES Solar Tour Saturday, October 1, includes open houses at about 50 Minnesota homes, businesses and organizations that have solar and other renewable energy installations. Organized by the Minnesota Renewable Energy Society (MRES), the tour includes open houses in the Twin Cities and several other Minnesota communities from 10 a.m. to 5 p.m.

For the first time, this year the online guide to sites at will list each site’s additional eco-friendly features. Besides the usual pictures, maps and details about alternative energy technologies for each site, the guide will list eco-friendly features such as urban chickens, electric cars, rainwater storage systems and the like. Tour guests must register at to obtain addresses of the tour sites.

“The solar tour is popular with people who are thinking about purchasing some kind of renewable energy technology because it gives them a chance to see lots of systems and talk to lots of owners,” said Laura Cina, managing director of MRES. “The lists of other eco-friendly site features this year should draw even more people to the event.”

The owner, representatives from TE Studio, as well as representatives from Energy Concepts will be on site during the day to answer your questions.

Zero Energy

April 7th, 2011 by Tim Delhey Eian

The March electricity bill and meter readings show that the home was zero energy during the month. After a long and cloudy winter we are now observing surplus energy generation, which will offset the winter-use of electricity.

On a related note, the energy monitor is showing that the PV systems produce at near the nominal output they are rated. Over the last week we’ve seen 4.4kW and more out of the 4.68kW-rated arrays.

Meanwhile, we are on the quest for carbon-neutral operation. Again, with a very cloudy winter that yielded neither great passive solar heat gains, nor plentiful active solar electricity and hot water, we are excited to see all sources pick up now on the way to carbon neutral operation.


Student Tour

April 7th, 2011 by Tim Eian

We are welcoming students from the University of Minnesota this weekend for a tour and lecture at the Passive House in the Woods. Unfortunately, the event is not open to the public but we hope to offer public viewings again some time this year. Stay tuned.
