WALK YOUR PROPERTY IN AN OUTAGE
What stays on at your
Mapleton home?
Mapleton is large-lot bench homes below Maple Mountain and Spanish Fork Canyon, with strong canyon winds, animals and irrigation on acreage, and frequent 400 amp services. An outage here reaches well past the house. Tick what you refuse to live without. The planner adds the energy and the peak power, then gives you a preliminary Powerwall range to bring to your Zoom.
Whose name is on your power bill?
Planning estimates using typical residential loads. Your nameplates, your panel and your utility's requirements decide the real design.
WHY TESLA HERE
One system.
One manufacturer.
One answer when it matters.
Backup is a chain: panels, inverter, battery, the gateway that disconnects you from the grid, the app, the EV charger. In most quotes those links come from three or four companies.
Tesla builds the whole chain. Powerwall 3 has the solar inverter inside it. The Gateway, the app and the Wall Connector are designed to work as one system, under one manufacturer's warranties. When the grid drops, there is no question about which brand's box was supposed to react.
Mike learned this at his own house. He bought solar, then added batteries. When his neighbors posted about losing power, his lights and appliances kept working. That is the standard a Mapleton design is held to: what do you want to keep doing when the lines go down?
Mike's experience, paraphrased. Backup coverage and duration depend on your system and loads.
| When the power is out | Tesla integrated system | Mixed-brand battery system | Portable or standby generator |
|---|---|---|---|
| Switchover | Automatic through the Gateway | Automatic if the brands' controls are configured to work together | Manual start, or automatic with a transfer switch |
| Refuel | Sun recharges the battery each day | Sun recharges the battery each day | Propane, gas or diesel on hand |
| Who owns a fault | One manufacturer, one app, one warranty path | Depends which brand's component failed | Engine service and fuel supply |
| Everyday value | Works every day, not only in outages | Works every day | Sits until needed |
A mixed-brand system can work well. The difference is who is accountable when one part stops talking to another.
CHECK THEIR HOMEWORK
Mapleton sits on a utility line. Your quote should know which side you are on.
Homes in Mapleton are served by Rocky Mountain Power or SESD. Which one depends on your address, not on the city name in your mailing address.
Different utility. Different application. Different rebate. Different value for the power you send back. A quote that assumes the wrong one is wrong before the design starts.
A family doctor can read your chart. You still want the surgeon for the operation. Confirming your utility, then designing Tesla for that rulebook, is the operation we do.
Pick your utility. See your rulebook.
- Solar connects under Rocky Mountain Power's net billing program (Schedule 137). Power you export earns a published credit rate that is lower than the retail rate, which is why battery sizing matters.
- The Wattsmart Battery program pays a $2,000 enrollment incentive for a single battery of 10 kW or more. Powerwall 3 at 11.5 kW qualifies. It carries a four-year commitment. Source ↗
- Rocky Mountain Power reviews the interconnection application and must approve the system before it operates.
- Building permit: Mapleton City Building Department. Source ↗
- SESD (South Utah Valley Electric Service District) publishes its service areas and map. Source ↗
- Solar connects under SESD's Net Feed-In-Tariff Service for homes up to 25 kW. Source ↗
- An Interconnection Agreement and an application go in, SESD inspects, and the system may not run until SESD approves it in writing.
- The Rocky Mountain Power Wattsmart battery rebate does not apply to SESD customers.

Published fees, for the detail-minded
$100 application processing fee and a $560 meter fee collected after inspection and before the meter is connected (policy updated November 8, 2023). We handle the paperwork.
- Look at the top of your power bill. It will name your utility: Rocky Mountain Power or SESD.
- Your neighbor's utility is not proof of yours. Service territories in Utah do not always follow city limits.
- Bring the bill to your Zoom. Confirming the utility is step one of every Mapleton plan we build.

MAPLETON QUESTIONS
Clear answers.
Sources attached.
Who provides electricity in Mapleton, Utah?
It depends on your address. Homes in Mapleton are served by Rocky Mountain Power or SESD. Which one serves you depends on your address, so we confirm it on your bill before we design anything.
Does the Rocky Mountain Power Wattsmart battery rebate apply in Mapleton?
Only if Rocky Mountain Power serves your address. Homes on SESD are not eligible. The 30% instant rebate through the Tesla pre-paid PPA program is not tied to your utility.
Is my Mapleton home on Rocky Mountain Power or SESD?
Most Mapleton homes are on Rocky Mountain Power, and the city itself provides no electricity. The South Utah Valley Electric Service District also lists Mapleton as a city it serves alongside the other provider, so some addresses are SESD. Ask Solar Mike confirms your provider from your bill before quoting, because the solar rules differ.
Can a Tesla Powerwall 3 run a well pump or air conditioner?
Often, yes, and it is decided by the nameplate, not a guess. Powerwall 3 delivers 11.5 kW of continuous power and is rated for 185 LRA motor starting. Ask Solar Mike reads the nameplate and confirms the design at site verification.
How many Powerwalls does a Mapleton home need?
It depends on what you keep running and for how long. Each Powerwall 3 stores 13.5 kWh. Essentials such as heat, refrigeration, lights and internet often land in the one-to-two range. Air conditioning, a shop or EV charging move it higher. The planner on this page gives a preliminary range.
I have 400A service. Does that change the design?
Yes. Ask Solar Mike designs for 200A and 400A service panels. A 400A home is an engineered gateway decision. Whether you get whole-home or essential-load backup is confirmed at site verification.
Who issues the building permit for solar in Mapleton?
Mapleton City Building Department. Ask Solar Mike handles design, contracting, permitting coordination and project management.
What happens at year 6 of the pre-paid PPA?
The system is scheduled to transfer to the homeowner around year 6. The Ask Solar Mike $0 Transfer Guarantee puts it in writing: the buyout cost at the scheduled transfer is $0, and if the PPA provider charges more, Ask Solar Mike covers the difference.
