CT Solar Deadline 2027: Why Smart Homeowners Are Installing Now
Connecticut’s prepaid solar lease program and the SunPol's 30% discount both require your system to be installed and producing power by December 31, 2027. With permitting, engineering, and utility approval taking 4–8 weeks, the real deadline for starting the process is much sooner than you think.
The 30% federal solar tax credit (ITC) begins stepping down after 2032, but Connecticut’s Prepaid Solar Lease program and current incentive stack may not last beyond 2027. Smart homeowners are locking in today’s pricing before rate hikes and program changes reduce the savings window.
What Exactly Is the 2027 Deadline?
Two major financial incentives are tied to a December 31, 2027 installation deadline:
- SunPol's 30% Discount — SunPol's 30% discount applies to systems “installed and producing power by December 31, 2027. However, After this date, the discount may no longer be available. Starting sooner means locking in the full savings plus extra months of energy production you’d otherwise miss.
- SunPol’s Prepaid Solar Lease ($0/month) — This program requires your system to be installed and interconnected to the grid by late 2026. Slots are limited by crew availability and permitting capacity. Once the installation calendar fills up, no new prepaid leases can be started.
- Connecticut Net Metering (Full Retail Credit) — Current net metering rules give you full retail credit for every kWh you export. Connecticut is reviewing these rates. Systems installed under current rules are grandfathered. Waiting risks worse terms.
⚠️ The Real Deadline Is Earlier Than December 31
Your system must be installed, inspected, and approved by Eversource/UI before the deadline — not just contracted. That means you need to start the process at least 6–10 weeks before December 31, 2027. Realistically, that’s mid-October 2027 at the latest to begin.
And that’s assuming no delays. Crew schedules fill up as the deadline approaches. The permitting office gets backlogged. The smart move is to start now while timelines are comfortable.

Why Waiting Costs You Real Money
Every month you delay is a month of paying Eversource/UI at 32¢+ per kWh instead of generating your own power. Here’s what that looks like:
Connecticut electricity rates have increased an average of 4–6% per year. Rates will be higher next year than they are today. Every month your panels are generating power is a month you’re protected from that escalation.

What Happens If You Miss the Deadline?
- SunPol's 30% discount ends — This discount is only available for systems installed by December 31, 2027. On a $30,000 system, that’s $9,000 you’d lose.
- Prepaid lease may not be available — SunPol’s $0/month prepaid lease requires installation by late 2026. After that, availability depends on program renewal.
- Net metering terms may worsen — Connecticut is actively reviewing solar compensation rates. Systems installed under current rules are grandfathered. New installs may get lower credits.
- Higher electricity costs — Every month without solar = another month paying Eversource’s rising rates in full.
Which Connecticut Towns Are Best for Solar?
Every town in Connecticut has excellent solar potential. Homes with south-facing roofs, moderate shade, and Eversource or United Illuminating service see the strongest returns. Here are some of the top towns where SunPol is currently installing:

Frequently Asked Questions
Is the 30% discount really going away?
The 30% Investment Discount is currently available through 2032 for cash purchases. However, the prepaid lease program and SunPol’s current pricing structure are tied to installation capacity in 2026. Once slots fill, the program closes for the year regardless of the federal credit.
What if my roof needs work first?
SunPol evaluates your roof during the design phase. If it needs repairs or replacement before panels go on, we’ll tell you upfront — and factor that into the timeline. Starting the conversation now gives you time to handle roof work without rushing.
Can I still go solar after the deadline?
Yes — solar will still be available after 2026. But the combination of the full 30% discount + $0/month prepaid lease + current net metering rules + today’s lower panel costs creates a window that may not repeat. Each of these factors is subject to change independently.
How do I know if my home qualifies?
Most Connecticut homes qualify. You need: a roof with some south/east/west exposure, reasonable shade conditions, and an Eversource or United Illuminating account. The fastest way to find out is to request your free solar design — SunPol will tell you within 24 hours if your home is a good fit.
