In May, we added a new PV system to provide ~72% (.72 SF) of our annual electric energy at Heliotropic Technologies.  Because we’re a wicked efficient operation, it only required a 1.35 kW system, which provides ~100% of our summer electricity needs, and ~70% of the Spring/Fall requirements.  With the state and federal tax credits and incentives combined with low interest rates, we’ve locked in our electric expense for the next 12 years at a lower cost than the “Green Power Option” grid-supplied electricity that’s being displaced.  After 12 years, this system (at retail cost) should provide us with virtually free energy that will then likely provide us with a S.F. of 1.0 (net-zero electric if we become ~30% more efficient by then).

Let us help you do the same.  It’s similar to the difference of owning your house versus renting, except owning the solar system will be less expensive than purchasing grid-supplied power.

I can recommend Mike Mayhew coolsolarguy@yahoo.com in the Boothbay Harbor area. He has been a member of the Maine Solar Energy Association (MeSEA) for years and does very nice installaions at an honest price. You can go to our www.mainesolar.org website to find more information about MeSEA and see our calendar of upcoming events.
Thank you for using solar energy,

Solar Hot Air System financial analysis -2012

The 2011 Heliotropic Technologies HQ Green Home Tour Write-up.

Our proposed 36′ x 15′ site-built solar hot air collector, at a Maine manufacturing firm should reduce propane consumption expenses by over $5,000/year. The cashflow from this commercial project only requires financing with an $11K loan over a 5 year term, for the $36K project cost, and as soon as it’s built, the project becomes cashflow positive, generating >$200K in fuel savings over its projected life.
