What You Need to Know
Grid Tied PV Cedar-sided contemporary built with local (Maine grown) cyprus and lots of drift wood. Three levels of decks with great elevated ocean views of Boothbay Harbor. 2,0 W PV system & solar powered hot water system, attached green house with 1000 gallon thermal storage pond,efficient lighting, condensing boiler, radiant heated floor, passive heating, daylighting and efficient appliances. Working engineering & sales office, as well as home to 6 with ~$10/month electric bills. 4 bedroom home with office, and large kitchen, living room and attached greenhouse located on Campbell Street on the East side of Boothbay Harbor.
The house is a very warm, healthy and sunny place to be. We start plants early in the spring and have a great green and growing place throughout the winter. This home serves as our working sales tool for renewable energy systems and efficient technologies.
The SHW system requires matenance, flushing out the heat transfer fluid every 4-5 years and the solar preheat tank needs its sacrificial anoids replaced every 7-8 years. Occationally, snow is raked off the collectors if there is a large storm. The PV system is practically maintenance-free.

I am an environmentalist, enjoy carpentry and have been a solar enthusiast since I was in middle school. My business, Heliotropic Technologies, an energy engineering services and renewable energy business operates out of this location. Needing a showroom for products, these working systems made a lot of sense to have on property.
Hire Heliotropic Technologies to develop a strategic energy plan, and then have them install your energy efficient systems.
Experience with Installer:
I've had to train many of the trades-people that contributed to creating this home. All in all, my subcontractors were great! I stayed very involved in the projects. so that everything went smoothly. If you have the time and abilities, I'd recommend that. If you don't, I'd hire a good project manager. (Please check with Heliotropic Technologies for project manager availability.)

This was an existing seasonal cottage that was situated with very good southern exposure and elevated ocean views, that has been retrofitted into a super-efficient cool place. It was not torn-down, but cost-effectively improved and is now a local landmark. Latest tower/dormer addition has R-80 ceiling & R-45 walls insulated with urethane foam and reflective barrior.
