Solar Legacy Projects

Solar Legacy Projects are solar energy installations built on community institutions like schools, libraries, or churches. They have been designed and built by local stakeholders.  We call them “legacy” projects because solar generates pollution-free electricity for the community and future generations long after it’s installed –– often 30 years or more. 

You too can help support these projects through our Slice of Sun Solar Bonds program.  Any member can earn between 3% and 5% interest on their bonds purchased through the co-op. Your contribution by purchasing solar bonds allows us to help finance these community projects. After 7 years a bond holder can receive a dividends payment or choose to reinvest at a higher interest rate.  

So even if you live in the shade you can actively help grow solar energy in Wisconsin!  Learn more about the Slice of Sun Solar Bonds program

First building

Housing Initiatives of Madison

Housing Initiatives is a Madison nonprofit organization that has been providing peace, hope, and shelter for Madison area men, women, and veterans for over 20 years.

The Challenge

Housing Initiatives own several buildings throughout Madison to give their clients a safe, warm place to call home. Residents use a lot of electricity because they are home often and at a variety of times. Energy for heating and lighting is a significant recurring expense.

In the summer of 2016, a supporter of Housing Initiatives (and of solar power) approached Legacy Solar Co-op to see if we could facilitate a solar project on some of their units.   Read more

Legacy Solar Co-op will provide solar on 2 buildings that Housing Initiatives owns and maintains.  Our tax sponsor for this project is a long-time advocate for this and other organizations in Dane County.  Together, we will help Housing Initiatives achieve lower energy bills by helping them generate their own electricity behind-the-meter, saving them about 40% on their power bills.  Read more

Legacy Solar Co-op teams with MREA on solar carport project

Legacy Solar Co-op is working with the MREA to develop a 100 kilowatt solar carport to be located on the main grounds of MREA’s headquarters in Custer, Wisconsin.  We will rely on supporters of MREA and members of LSC to buy Solar Bonds to capitalize a fund that will allow MREA to get the best value out of this development.

LSC is looking to sell $240,000 in solar bonds through our Co-op to get this project off the ground this summer!

Learn more about solar bonds and how they help fund community solar projects like this one – while earning you interest!
