San Francisco catches on to bulk solar purchasing by using Groupon model
In an effort to boost the city’s solar energy use, San Francisco officials have launched a pioneering program keying in on a simple model: group discounts.
Solar@Work, developed by the city’s Department of the Environment and the National Renewable Energy Laboratory, encourages commercial business owners to join together to create one solar purchasing group. The larger the group, the cheaper each owner’s cost.
