The age of solar has arrived. With prices falling by 80% in less than a decade, solar power is now within reach of every American household. Here’s the problem: 90 million American households are currently locked out of the solar marketplace. Maybe it’s because they rent their homes. Or other solar companies are not willing to sell to them. Or simply because their roof is in the shade or is not well-suited to a solar array. Our mission is to unlock the possibility of solar power for these households. With the help of transformative policies taking root in the United States, we are now in a position to do so. It's called "community solar."​ What it means is that a household can buy solar power without having an array installed on its roof. Here's what we noticed: in communities all across the country, there are extraordinary organizations -- from the church down the street to the college campus across town -- that are embracing clean energy and want to bring it to their constituents. There are also households that want to go solar but do not have an easy way to do so. Finally, there are solar companies eager to find more customers. Our goal as Solstice is to use community solar to help these groups meet one another. When we do, everybody wins: those who cannot currently access solar are brought into the market, more solar is deployed, and everyone saves on their electricity bills.
