Solar power in Connecticut

Solar power in Connecticut makes Connecticut the second state in the US to reach grid parity, after Hawaii, due to the high average cost of electricity.[1] Installing solar panels for a home provides an estimated 15.6% return on investment.[2]

Solar break-even cost

CT Solar Lease was a program to install solar panels at no upfront cost, and a fixed lease price for 15 years, with an option to extend the lease for 5 years at a reduced cost. CT Solar Lease owns and sells the RECs generated by the system, but turns over all but $15/REC plus 100% of the sale over $30 or 50% of the sale of the REC up to $30/REC to the homeowner in a Solar Dividends account for maintenance and to allow the purchase of the system at the end of the lease. RECs have been selling for from $18 to $24 each. Applications ended on August 19, 2011.[3]

Regulations

Connecticut's renewable portfolio standard requires 7% of power in the state will be from renewable resources by 2010, and 23% by 2020.[4] A bill passed in 2011 requires incentives that will produce at least 30 MW of new residential PV installed by the end of 2022.[5] Net metering is available for all up to 2 MW sites, and is reconciled annually at either the avoided cost or the time of use/generation rate, which is higher but requires time of use metering.[6]

Potential generation

The average insolation in Connecticut is about 4 sun hours per day, and ranges from less than 2 in the winter to over 5 in the summer.[7]

Connecticut electricity consumption in 2005 was 33,095 million kWh.[8]
