About Solar Bonds

Growing Wisconsin Solar for everyone is our Legacy

The Slice-of-Sun solar bonds program allows Co-op members to help fund our Co-op’s investments into community solar projects and earn up to 4% interest on your Member Co-op bonds.

Each $250 solar bond (your slice-of-sun) is the equivalent of roughly one solar panel, making the price to participate about $1.00 per Watt. That’s cheaper than buying solar for your own home. It’s also lower than any utility sponsored community solar program because we don’t have to pay shareholders 15% or more in profits to stay in business.

Legacy Solar Co-op offers two types of bonds:

Interest for Good bonds: You choose to donate up to half of the interest you earn to a nonprofit of your choice.

Interest Choice bonds: Depending on the amount of your purchase, you choose how much interest you earn, up to 4% over a 12 year term. You receive Principal and Interest payments annually.

Investment in solar bonds reflects my values more than the “traditional” retirement investments we are taught to embrace. [My investment] helps advance the move to a renewable energy-based society and otherwise help build a world I wish to live in and for those who come after me. I encourage those of you with “extra” funds to invest in solar bonds and the Legacy Solar Coop.
