What You Need to Know
Efficiency or Sustainability Improvements:
added insulation and tightened windows; new construction/renovation planned for 2014 will maximize energy efficiency; a ground-source heat pump is under consideration.
My Motivation:
commitment to reduce carbon footprint; budgetary savings; highly visible location can provide example/encouragement to the larger community
Advice:
Get multiple quotes! Different installers have different-quality products and designs, as well as different financing arrangements. EnergySage was very helpful in sorting through the proposals we received, resulting in our saving of over 30% compared to the initial bid from SunBug.
Additional Notes:
attaching the solar panels to the copper roof by using clamps on the roof's standing seams avoided penetrating the metal roof
