Wisconsin Solar Group Buys

The solar group buy is a proven format for reducing solar energy installation costs for residences in a geographically defined area. In a group buy a designated contractor works with a particular community or communities to provide solar electric systems at a predetermined price per kilowatt. The contractor partners with a nonprofit entity to organize materials and outreach events, arrange for site visits, and set a price for solar installations. Group purchasing enables contractors to acquire solar equipment at a lower cost and reduce marketing costs, and those savings are then passed through to solar system owners.

The Wisconsin group guy model uses trusted nonprofit organizations to find and educate dozens of customers to install solar.  This approach reduces marketing, customer acquisition, and solar equipment costs, and the savings are passed on to the new solar customers.
