Why Killingly Homeowners Pay Too Much for Electricity — And How Solar Fixes It
Connecticut has some of the highest electricity rates in the United States. According to the U.S. Energy Information Administration (EIA), Connecticut's average residential electricity rate is approximately 32.5¢ per kWh as of early 2026 — nearly double the national average of 17¢/kWh. Killingly homeowners on Eversource are paying these rates every month with no control over future increases.
Over the past decade, Connecticut electricity rates have increased an average of 3–5% per year. At that trajectory, a homeowner currently paying $200/month could be paying $320–$370/month within 10 years — without using any more electricity. Over 25 years, a typical Killingly household will pay $70,000–$120,000 to Eversource if they do nothing.
25-Year Cost Comparison for Killingly Homeowners
- Without solar (Eversource, 3-5% annual increases)$70,000 – $120,000
- With SunPol prepaid lease (one payment, $0/mo for 25yr)$18,000 – $45,000
- Your estimated savings$30,000 – $60,000+
Source: Savings estimates based on average system sizes of 7–12 kW, current Eversource rates, and historical 3–5% annual rate increases. Individual results vary by roof, usage, and system size.
Solar effectively locks in your electricity cost at today's rate — or lower. With SunPol's prepaid lease, you make one payment and your monthly electric cost drops to $0 for 25 years. With our PPA, you pay a per-kWh rate lower than Eversource's current rate from day one, and it never increases at the same pace as utility rates.
According to Zillow research, homes with solar panels sell for 4.1% more on average than comparable homes without solar. For a median-priced home in Killingly, that translates to approximately $12,000–$18,000 in added property value — and Connecticut's 100% solar property tax exemption means your taxes don't increase even as your home value rises.
The National Renewable Energy Laboratory (NREL) confirms that Connecticut receives sufficient solar irradiance — approximately 4.0–4.5 peak sun hours per day — to make residential solar highly viable year-round, including during winter months when panels still produce 60–80% of their summer output.
