Connecticut Clean Energy Fund, a state-run and utility funded agency to promote the advance of renewable energy in CT, has increased rebate rates for solar hot water, in some cases as much as 60%. At $275 per thousand BTU per day, a two panel system with adequate tanks, connected to your existing hot water system, might yield a rebate of as much as 5500 dollars, over half the cost of the system. Add in federal tax incentives, and you get renewable, clean energy for about a third of the market cost, and a resulting payback under five years. The system I installed at our house has yielded free hot water from march to october, and will pre-heat hot water to save us money all winter. if you’re interested, give us a comment or a message.
