The Solar Installation Process & Timeline
What happens from first conversation to permission to operate, how long it takes, and what to expect at an in-home review.
How long does it take to install solar in DFW?
Installation day itself is often one to two days, but the full process — design, HOA approval, city permit, install, inspection and utility permission to operate — commonly takes several weeks to a few months. Permits and utility approvals are the usual bottlenecks. Ask for a written timeline with each milestone.

What happens during a free in-home solar consultation?
We review your last 12 months of electric usage, your roof and shade, your electrical panel, and your goals — lower bills, backup, or both. You leave with a clear design, a price, and your ownership options (cash or solar loan), with no pressure to sign that day. Have a recent electric bill handy; it makes the estimate far more accurate.

What questions should I ask a solar company?
Ask: Are you and your salesperson registered with TDLR? Who is the licensed electrical contractor doing the install? What is the price per watt and the 25-year total cost? What production does the proposal assume, and how was shade modeled? What warranties cover panels, inverter, battery and workmanship — and who services the system?

What is permission to operate (PTO)?
Permission to operate is the utility’s approval to switch on a grid-connected system after it passes inspection. Turning a system on before PTO can violate your interconnection agreement. In Oncor territory, your installer handles the interconnection application.

Do I need to be home for solar installation?
Usually someone needs to be available at the start and for any work inside the house, such as the main electrical panel or battery placement in the garage. Inspections may also need access. Your installer should give you a day-by-day plan.

How do I compare solar quotes?
Line them up on the same terms: system size (kW), estimated annual production (kWh), price per watt, total 25-year cost, rate or payment escalator, equipment brands, battery size, warranties and cancellation terms. Check that the production estimate fits your roof and shade. A second-opinion review of a proposal you already have is free with us.
