From the first 15-minute call to a working solar system on your roof. Tracked across our last 12 months of CT, MA, and RI installs. Refined through 9,000+ Team Sunshine installs.
A 15-minute call, then a remote or on-site visit. Aurora-based design, panel and battery brand named on the proposal.
Permits filed, utility interconnection submitted, and equipment staged at our Bristol warehouse.
Local crew, local trucks. Most homes finished in 2 – 3 days. Final inspection scheduled before we leave.
PTO from your utility, ITC and rebate paperwork filed, and 25 years of local service after the system goes live.
The 47-day median, broken into the 10 milestones we hit. Some of these run in parallel — the timeline below is real-world, not a sequential chart.
Day 0
Phone, web form, or email. Lands in our Bristol office.
Day 1 – 2
We confirm your address, utility, and rough scope. No pitch, no closer — a designer who knows your town.
Day 3 – 7
Crew lead walks the roof, measures, pulls a load calculation on your panel, and confirms what we discussed remotely.
Day 8 – 14
Engineering pulls satellite imagery, models shading hour-by-hour, and produces a written proposal with the exact panel and battery brand named on it.
Day 14 – 21
No follow-up unless you ask. Cash, loan, PPA, or PPL — we walk you through the math, you sign when it makes sense.
Day 21 – 35
Town building/electrical permits filed within 48 hours of contract. Utility interconnection submitted in parallel. Your AHJ timeline drives this window.
Day 35 – 45
Panels, inverter, racking, and battery (if any) arrive at our Bristol warehouse and get staged for your truck. We do not buy "best price" — we buy what is on your proposal.
Day 45 – 47
Local crew, local trucks. Most homes finished in 2 – 3 days. Final inspection scheduled before we leave the roof.
Day 47 – 60
After town inspection, your utility issues Permission to Operate. We commission the system, run the monitoring app on your phone, and hand off the project file.
Year 1 – 25
Manufacturer warranties cover panels for 25 years, inverters for 10 – 25, batteries for 10 – 15. We service the system long-term — call our Bristol office and a person picks up.
The decisions we made years ago that we do not relitigate per project. They keep the timeline honest and the equipment named.
We do not quote without a real Aurora model. Production estimates are conservative on purpose — most customers exceed them in year one.
No "Tier 1 equivalent" language. The exact panel brand, inverter brand, and battery model are written on the page. No swaps at install.
The lead tech who walks your roof at the site visit is the same lead who runs the install. Continuity is a deliberate choice, not an accident.
Year 5, year 10, year 25. The Bristol office number does not route to a call center. Your service question lands on someone who knows your project.
“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.”
Yes — measured across our last 12 months of CT, MA, and RI installs. Some projects are faster (clean permits, simple roofs land in 30 days). Some are slower (historic districts, custom permitting can stretch to 70+ days). 47 is the median.
Permitting and utility interconnection together — usually 20 – 30 days. The on-roof install is only 2 – 3 days; the rest is paperwork. Some towns are faster than others; we know which ones from 9,000+ installs.
Sometimes — if your AHJ is fast, your utility processes interconnection quickly, and your project is simple, we have closed in 28 – 35 days. We will not promise sub-30-day timelines because they depend on parties outside our control.
We tell you why and where. Most slips are AHJ permitting (not our control) or utility interconnection (also not our control). Equipment shortages and weather delays we own and absorb the cost. Communication is on us — you hear about a slip the same day it happens.
Briefly — we like to do a 15-minute walkthrough on day one to confirm the site plan, and a 30-minute commissioning walkthrough on the last day. The middle days you can be at work. We need access to the electrical panel, which usually means a key or someone home for one morning.
The crew lead measures the roof, takes shade-relevant photos, opens the electrical panel to confirm capacity, and walks any access challenges (steep pitch, attic conduit routing, battery placement). 30 – 60 minutes total. Aurora design is finalized within a week after the visit.
Yes. Aurora pulls satellite imagery from current Pictometry and Google data, traces every roof plane, and models shading hour-by-hour for every day of the year. Production estimates use your actual local solar irradiance, your actual utility rate schedule, and your actual roof geometry — not a generic "average home" template.
The 15-minute discovery call is always remote. Final design requires the on-site visit because we need accurate measurements and electrical-panel context. Some early-stage exploratory work can be fully remote with satellite-only Aurora models.
A 15-minute call with a designer who knows your town. No closer on the line. No follow-up unless you ask for one. $0 down options available.
