Most installers leave the paperwork to you. We do not. Every Teamsun project includes turn-key incentive paperwork as part of the install fee — never a separate line item.
Commercial ITC cost-basis paperwork, CT ESS enrollment, MA Connected Solutions registration, RI REG application, net metering tariff selection. You sign; we submit.
Aurora produces a one-page summary on every quote that lays out federal + state + utility incentives in plain English. No surprise math at install.
Some programs run on enrollment caps and quarterly blocks. We know which programs are open this month and queue your project to land before each cutoff.
When the utility mails you a Connected Solutions check three years from now, you can call our Bristol office and ask what it is for. A person picks up.
“Teamsun was the only crew that walked the roof, named the panel brand, and answered every question without checking with someone. Same lead tech came back a year later when I added a battery.”
“Three of my neighbors had Teamsun, so I called them. The crew was on my street five days after I signed.”
“They knew the historic district secretary by first name. Saved us six weeks on permitting alone.”
“Same lead tech who installed it came back four years later to swap an inverter under warranty. No charge, no excuses.”
On a typical $30,000 Connecticut residential install, the combined incentive stack (CT ESS, net metering, property and sales tax exemptions) plus high-energy-cost bill savings still bring the effective cost well below sticker — roughly 30 – 50% lower over the first five years. Residential ITC no longer applies in New England, but our systems will always save you money. Commercial systems also stack up to 40% federal ITC. We model your specific stack on every Aurora-based proposal.
For commercial systems: yes. The up-to-40% federal ITC is filed with your tax return; state programs (CT ESS, MA Connected Solutions, RI REG) are administered by your utility or a state agency. Teamsun files the state and utility forms; your CPA files the federal one using the cost-basis paperwork we provide. Residential ITC no longer applies in New England.
For commercial PPAs: the third-party owner claims the up-to-40% ITC, and you benefit indirectly through a lower fixed rate per kWh. Cash and loan structures let commercial owners claim the ITC directly. Residential ITC no longer applies in New England, so this question is mostly commercial.
Commercial federal ITC remains available at up to 40%. State and utility programs (CT ESS, MA Connected Solutions, RI REG) are subject to annual program-year caps and rate adjustments. Once you enroll, your terms typically lock for the program duration (5 – 20 years depending on the program). Residential ITC has been removed in New England.
Yes — CT ESS and MA Connected Solutions both accept battery-only enrollments. CT ESS starts at a $5,000 minimum rebate and can cover up to 100% of the battery cost depending on location. RI requires solar to participate in REG. Commercial battery installs also remain eligible for up to 40% federal ITC.
Most state battery incentives accept retrofitted batteries on existing solar systems — see our battery retrofit service. CT ESS and MA Connected Solutions enrollment paperwork is identical to a new install. Commercial retrofits remain eligible for up to 40% federal ITC on the battery cost.
No. We provide the cost-basis documentation your CPA needs to claim the commercial federal ITC and state credits, but we do not file federal tax forms for you. Always consult a tax professional for your specific situation.
