Solarize MDI Doubled our Solar Capacity on MDI! 


In April when we launched our Solarize MDI campaign, Mount Desert Island had a total installed capacity of 646 kW of solar photovoltaics - representing incremental growth over several decades. By our August 15 deadline, just four months later, we had secured 76 home, business, and municipality solar installation contracts totaling 643 kW through our Solarize MDI partner, Revision Energy!  And, we saved 76 customers (see map below) over $160,000 on solar installs. Our thanks goes out to Bar Harbor Bank & Trust, our dedicated ACTT Volunteers, MDIslander, and everyone else who helped make Solarize MDI the most successful Solarize program in Maine!

Want to Install Solar Photovoltaic Panels in 2018?

While there is no official Solarize MDI program this year and thus, no bulk purchasing discounts, 2018 is still a good year to go solar. The grandfathering clause offered by the Public Utility Commission that gives you 15 years of full credit for each kilowatt hour produced, which was set to expire in 2017 has been extended through April 30, 2018. Also, Emera Maine has requested a 4-5%  increase in electricity costs which will add to your future savings.
