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.
