Fast-Start Promises and Months of PTO Delays

Panels on your roof don’t mean power for your home. Before a grid-tied system can be switched on, it usually needs a building or electrical permit, an installation, a city or county inspection, and Permission to Operate (PTO) from your utility. If you have an HOA, add its approval at the start. A rep who promises you’ll be “saving in a few weeks” is guessing at best. Delays themselves aren’t a scam. The red flag is a fast-start promise used to close the sale, combined with a contract that leaves you paying while you wait.

Why salespeople promise speed

A quick timeline adds urgency and makes savings feel immediate. It also distracts from the part of the process the installer doesn’t control: your city’s permit office, your utility’s interconnection queue, and your HOA’s architectural review.

The real steps

Step	Who controls it	What can slow it down
HOA approval (if any)	Your HOA	Review meetings, design requirements
Permit	City or county	Backlogs, plan corrections, structural review
Installation	Installer	Crew schedules, equipment supply, weather
Inspection	City or county	Scheduling, failed items needing rework
Interconnection and PTO	Your utility	Application backlogs, meter swaps, upgrades on the utility side

Timelines vary widely by location, so ask local installers how long PTO has actually taken for their recent customers in your utility territory. Our guide on interconnection and PTO explains each step, and solar HOA rules covers the HOA side.

A worked example: what a delay costs

Say an 8 kW system would produce about 870 kWh a month (production varies a lot by location and roof; check yours with our production checker, which is based on the national lab’s PVWatts model). At the U.S. average residential rate of about 18.3¢/kWh (EIA, July 2026), that’s roughly $160 a month in electricity you’d otherwise buy.

• A 4-month PTO delay means about $640 in savings you don’t get.
• If your loan payment of about $158 a month starts at installation, you also pay about $632 for a system that isn’t allowed to run, on top of your full utility bill.

That second part is why the contract terms matter more than the promise. See payments before PTO.

How it shows up in a contract

• No completion date, or a clause saying timelines are “estimates only.”
• Financing that starts on “installation” or “substantial completion” rather than PTO.
• A clause putting all permitting and utility delays on you.
• A note that you must not turn the system on before PTO. That part is legitimate: running it early can violate your utility agreement.

Questions to ask

• “In my city and utility, how long has PTO taken for your last few customers?”
• “Will you put a target completion date in the contract? What happens if you miss it?”
• “When does my first loan or lease payment start: installation or PTO?”
• “Who submits the interconnection application, and will you send me a copy?”
• “Do you handle HOA approval, and is my contract cancelable if the HOA says no?”

If you’re stuck waiting

Ask the installer for the permit number and interconnection application number, then check status with your city and utility directly. If the installer has gone silent, read what to do if your solar company goes out of business. If you’re paying a loan on a system that isn’t running, contact your lender in writing and, if needed, file with the CFPB. Unfinished work can be reported to your state contractor licensing board and attorney general.
