Renewable Energy Systems

Do you think that you might want to explore a renewable energy system for your home or business, but you’re not sure who to work with?  Maybe you like to work with a team that has been pushing the envelope for years.

Heliotropic Technologies has stayed the ‘Soft technology’ course since 1980, designing renewable systems and promoting energy conservation.  We have designed systems for customers and then written grants for some of them so that their implementation costs would be lower than if they had done it all by themselves.

We’ve designed solar additions for homes and installed solar hot water systems throughout Midcoast Maine for years, designed solar heated spaces for aquaculture projects, been a Sunwize Technologies and a Heliodyne Solar Hot Water Dealer, as well as a member of the Amercan Wind Energy Association long before it was fashionable.  Mr. Mayhew was the driving force (and a member) of the EPRI In-stream Tidal Power Project Development Team and helped turn the project into an international study, that has stimulated a great deal of interest on both coasts.

We are still creating new technology.  Our R & D division just received a seed grant from the Maine Technology Institute (MTI) to develop a new concentrating solar electric product for residences.

We also have plans to develop a hybrid solar hot water / solar electric concentrating collector and rain collection system that might be just the thing for your ecotourism center in the Caribbean.  (Please give us a call about it early next winter.)

If you’re serious about renewable energy systems or near zero energy design please give us a call today at (207) 633-1061 or email

We love brainstorming renewable energy systems and sustainable building design!
