It’s not easy being green, as the frostbitten peas, iced-over spinach, and cryogenically frozen aliens in your freezer can tell you. Get greener with today’s Groupon: for $99, you get $1,100 toward home solar-power panels and installation from One Block Off the Grid.

By organizing group discounts and vetting installers, One Block Off the Grid smoothes the solar-power installation process for homeowners looking to go green. The cost of an average system depends on a lot of factors, including the size and type of your roof and the rebates and incentives available to you. One Block Off the Grid monitors all these complexities to streamline the process for homeowners. Prices vary across the country ($6–$9 per watt in most areas), but One Block Off the Grid consistently negotiates pricing with installers to below $6 per watt. Tax credits and rebates can further reduce the total price of the system. Future sunshine stealers can log on to use a free online estimator that helps clients predict costs, and then join forces online with prospective solar-buying superheroes in their area.

Once a new group reaches critical mass, One Block Off the Grid will evaluate promising local solar installers based on 11 factors, and after a thorough vetting process, an installer is selected who will then deliver a heartfelt acceptance speech to bring tears to someone's eyes. One Block Off the Grid generally works with installers who offer members discounts of around 15% and at least 25-year warranties. Throughout this process One Block's army of advisers—who can stay impartial because they aren’t paid on commission—help homeowners decide whether to go solar now or wait until we can harness the power of the moon.

Not all homes are ideally suited for solar power; however, One Block Off the Grid will evaluate your home to ensure it is appropriate. Please note that your final billing will come from the chosen installer.
