What Should Happen During a Tesla Solar Site Survey?

A useful Tesla solar site survey should verify the serving utility, the main electrical service, the site conditions a licensed engineering firm needs for a design , and whether Powerwall 3 backup will be whole-home or essential-load . Ask Solar Mike is a Utah Tesla solar and Powerwall 3 specialist focused on correctly sized backup for larger homes , and we use that visit to confirm the house before permitting starts.

What should a Tesla solar site survey actually verify?

A satellite image, a utility bill, and a phone call are inputs. They are not a survey. Before anyone treats a Tesla solar and Powerwall 3 proposal as install-ready, the visit should lock down facts that change interconnection, backup architecture, and permitting .

• Confirm the serving utility at the actual address, because Utah service can change by street and cannot be guessed from the city name .
• Record the main service size. Ask Solar Mike designs for 200A and 400A service panels; the backup architecture is confirmed at site verification .
• Collect the roof planes, shading, attachment access, and electrical path a licensed engineering firm needs to produce and review a design .
• State plainly whether whole-home backup, essential-load backup, or more engineering is the honest outcome. Do not accept a universal whole-home promise before that verification .
• Check whether the utility is accepting export. Some Utah cities pause or refuse solar interconnection, and the design path changes if the system must never send power to the grid .
• Leave a written record of what was measured, photographed, and still unknown, so the homeowner can compare the later design to the house that was actually visited.

Ask Solar Mike handles design, contracting, permitting coordination and project management after that record exists . The survey is the first gate, not a courtesy walkaround.

Why does Utah utility confirmation come first?

Utility service in south Utah County varies by address — Payson, Spanish Fork and Salem run their own city power in parts of town, SESD serves others, and some pockets are Rocky Mountain Power . We confirm your serving utility as step one . Mapleton residents are on Rocky Mountain Power; Mapleton City does not provide electricity . Salem is Salem City Power, a municipal utility and Utah Municipal Power Agency member with net metering rules of its own .

That first confirmation decides more than a logo on the bill. Interconnection paperwork, export rules, and which battery incentives even exist all follow the utility, not the county line . The $2,000 Wattsmart Battery incentive for a qualifying Powerwall 3 is for Rocky Mountain Power customers on a four-year commitment . Naming the wrong utility at survey time is how homeowners get a design that cannot be filed.

Some Utah utilities pause or refuse solar interconnection or net metering . Ask Solar Mike can design a zero-export Tesla system: solar feeds your home and your Powerwall and never sends power back to the grid . That path is permitted through the building and electrical permit with engineered plans, with no net metering application . We confirm requirements with the city. This page does not claim a city has already approved a project .

Ask Solar Mike evaluates projects while serving homeowners across Utah . Based in Woodland Hills, Utah, serving all of Utah , we still start every design from the meter in front of the house, not from a statewide average.

What should the survey confirm about the electrical panel and backup?

Powerwall 3 backup is not a sticker you add after the panels look good. It is an electrical architecture. Ask Solar Mike supports homes with 200A and 400A main service panels for Tesla solar and Powerwall 3 backup designs . Whether a given home gets whole-home or essential-load backup, and gateway count, is determined at site verification and engineering .

A serious survey therefore opens the panel, or documents why it could not, and answers questions a brochure never will: Is this 200A or 400A? Where will the backup gateway live? Which loads are on the backed-up bus? What still requires the licensed engineering firm to decide ? Larger homes with higher electrical demand are exactly where those answers matter, which is why Ask Solar Mike is a Utah Tesla solar and Powerwall 3 specialist focused on correctly sized backup for larger homes .

If a salesperson promises whole-home backup from a photo of the street, the survey did not do its job. 400A homes can be served; the backup architecture is still confirmed at site verification . Tesla-focused design means matching Powerwall 3 to the house you have, not stretching a smaller battery story across a whole-home job. EG4 batteries are not on the PPA program's approved list . Enphase is PPA-approved, but its battery's continuous output is a fraction of Powerwall 3's — enough for essentials, not whole-home . Those hardware differences belong in the survey conversation and are spelled out on our Powerwall 3 vs Enphase vs EG4 comparison.

What does engineering review add after the visit?

Every system design is produced and reviewed by a licensed engineering firm . The survey feeds that firm. It does not replace it. Measurements, panel photos, roof planes, and utility notes become a design the homeowner can review. Diagrams on public pages are illustrative unless the stamped design is the customer's own .

Ask Solar Mike handles design, contracting, permitting coordination and project management; installation is performed by licensed, insured crews under our Utah contractor license . The site survey is how those later steps stay honest: permitting should describe the house that was visited, not a template that almost fits .

After install, the other bookend is delivery proof. You receive a commissioning receipt, registration proof, monitoring handoff, an ownership record, a named escalation path, and written change-order control . A survey that never wrote down the utility, the panel size, or the backup intent makes those later documents harder to trust.

What should you walk away with from the site survey?

Take a paper or email packet, not a memory of a confident tour. At minimum it should include the serving utility as confirmed on site , the main panel rating and any 200A/400A notes , whether backup architecture is confirmed or still in engineering, and whether export, net metering, or a zero-export Tesla system is the live path .

Pricing belongs after that packet, not instead of it. Site-specific quotes should show gross figures first and only then show net after incentives. Current Tesla solar and Powerwall installed figures live on our Tesla solar and Powerwall cost in Utah guide, including the rule that a site-specific quote is required . The federal Section 25D residential credit is not available for expenditures made after December 31, 2025 (IRS) . Do not let a 2026 survey still sell a closed federal credit .

Ask Solar Mike is a Utah Tesla solar and Powerwall 3 specialist focused on correctly sized backup for larger homes , Tesla-focused and quality over price . If the visit leaned on endorsement language, lowest-price theater, or a backup promise that skipped the panel, the survey failed the homeowner even if the calendar invite was on time .

Frequently asked questions

Can a Tesla solar design skip an on-site survey?

Not if backup architecture, utility rules, or a 200A/400A service have to be correct. Whether a given home gets whole-home or essential-load backup, and gateway count, is determined at site verification and engineering . Remote estimates can start the conversation. They cannot finish it.

What if my Utah city has paused net metering?

Ask the surveyor to confirm the serving utility and the current interconnection posture on the record . For utilities that pause or refuse export, Ask Solar Mike can design a zero-export Tesla system so solar feeds your home and your Powerwall and never sends power back to the grid . We confirm requirements with the city and do not treat that conversation as a permit in hand .

Does the survey decide Powerwall 3 versus another battery?

It should decide loads, service size, and whether whole-home backup is even on the table . Hardware choice then has to match that electrical reality and the PPA approved-battery list . Read the Utah Powerwall 3 comparison before you let a smaller continuous-output battery be sold as whole-home coverage .
