Brands we install

Pick what fits, not what they’re commissioned on.

National installers push whatever brand pays them the highest commission. We aren’t paid by any of these manufacturers. We pick what fits your house, your load, and your wallet.

Powerwall 3

11.5 kW continuous, 13.5 kWh. Most popular pick for whole-home Utah installs. Inverter built in.

Not Wattsmart eligible

We’re commissioned by zero of these brands. We pick what fits your house and load profile — and we’ll show you the math behind the recommendation.

Why a battery, why now

The math finally works.

Battery backup used to be a luxury for early adopters. Today, hardware costs have collapsed, multiple brands compete head-to-head, and Utah has a rebate stack that didn’t exist last year.

Battery prices finally make sense.

  • Cell prices dropped 40%+ in three years. The battery hardware on this page is at the bottom of the cost curve. There’s no “wait for it to get cheaper” argument anymore.
  • List prices reflect the new floor. Powerwall 3, FranklinWH aPower 2, SigEnergy — all list at the lowest they’ve ever been. The math that didn’t work in 2022 works now.

Stack $2,500 in rebates.

  • Tesla pays $500. Tesla’s Next Million Rebate — capped at 2 units per home, runs through June 30, 2026. We file the paperwork.
  • Rocky Mountain Power pays $2,000. Wattsmart Battery program — flat $2,000 per battery, eligible on Tesla, FranklinWH, SigEnergy, Sonnen, SolarEdge, Fortress, and Torus.

Backup that runs the whole house.

  • 11.5 kW continuous out of one Powerwall 3. Enough to start your AC, run the well pump, and bake dinner at the same time.
  • Not “essentials only” backup. Whole house. Lights, fridge, HVAC, work-from-home setup — nothing gets demoted to a critical-load sub-panel.
Our pricing

Common Utah battery installs and what they cost.

Every package is turn-key — permits, interconnection paperwork, install labor, inspection, and app setup all included. Prices below are after the $2,000 Wattsmart + $500 Tesla rebates. In rare cases (unusual roof, long wire runs, panel-side work) pricing can change — we flag it at the site check before you sign.

Solar customers welcome

Already have solar? Add a battery without your old installer.

Already have solar from Sunrun, Sunpower, Sunnova, Vivint, Blue Raven, or another installer? You can add a battery without going back to them. We design the interconnect, file the rebates, and install on your existing system. Most retrofits avoid panel upgrades.

  • Sunrun lease/PPA: You don’t own your panels, but you CAN add a battery on your service panel. Wattsmart still applies.
  • Owned solar (Vivint / Blue Raven / etc.): Easiest case. We tap your service entrance directly — no involvement from your original installer needed.
  • Enphase microinverters: Tesla Powerwall 3 + Gateway 3 work fine. SigEnergy is also compatible. Enphase IQ Battery 10 is the native option, but we don’t recommend it because it’s NOT Wattsmart-eligible — you’d give up the $2,000 rebate.
  • Older string inverters: May need to upgrade to a hybrid inverter, or you can pair AC-coupled with a Powerwall 3. We’ll quote the path transparently.

Honest recommendation

Why we recommend Tesla for most homes.

We install five brands. Here’s our honest take on why Powerwall 3 is the default pick — and when it isn’t.

01

Wattsmart eligibility decides $2,000 of value.

Of the brands we install, Tesla, FranklinWH, SigEnergy, Sonnen, SolarEdge, Fortress, and Torus all qualify for the $2,000 RMP Wattsmart rebate. Anker SOLIX X1 does NOT — that disqualifies it for most Utah homeowners. The Wattsmart rebate makes Tesla effectively cheaper than Anker even though Anker’s list price is lower.

02

One Powerwall handles 95% of houses.

11.5 kW continuous + 13.5 kWh storage runs your AC, well pump, and kitchen at the same time. We size up to 2 Powerwalls only if you have an EV charging at night or 3+ AC units. For everyone else, one unit is the right answer.

03

You’re not locked in.

If you want SigEnergy or FranklinWH instead, we install those too. We’re not Tesla-only — we just install Tesla most often because the math works for most people. Tell us your priorities at the site visit and we’ll quote the brand that fits.

What homeowners say after we’ve installed for them.

★★★★★

“Much cheaper to go with someone with Bat’s background than a big solar company. However, there is nothing cheap about his work. He does exactly what he tells you he will do.”

Larry Andrewa year ago
★★★★★

“I asked him to evaluate our solar. He suggested we NOT buy any more — just get 2 of our 14 existing panels serviced because they weren’t producing properly.”

Grant Wright11 months ago
★★★★★

“His prices were WAY lower than everyone else while still using quality products with 25-year warranty. It made solar actually affordable and obtainable for us.”

Georgea year ago
★★★★★

“I talked with 6 solar companies before. Tono Energy stood out — no sales pressure, prices were really competitive, install went very smooth.”

Larry (MSG DOC Wilson)a year ago
★★★★★

“One of those guys some would tease as being ‘too honest’ — he truly wants you to know everything about your transaction, even the nuances many would never mention.”

Eric Steelea year ago
★★★★★

“Bat’s engineering background gave me extra confidence. He is honest and knowledgeable, and he gave me a great price. Now I’m looking for more places to add solar.”

Greg Harris9 months ago
★★★★★

“I’m cautious about working with new tech and companies. Very satisfied with the professionalism, expertise, and support. I now have an extremely affordable backup system.”

Gary Rossa year ago
★★★★★

“Bat went beyond our hopes and expectations. The entire team was a joy to work with — efficient and effective installing 60+ panels in our 20kW rooftop system.”

David Beana year ago
★★★★★

“Amazing service and extremely knowledgeable. Honestly the best prices in town. I will absolutely be working with them in the future.”

Micah Hirokawaa year ago
★★★★★

“Bat was prompt in his responses, in working out a time for install, and in explaining every detail I needed to know. He even put up with my dogs!”

How to pay

How to pay. No leases.

The solar industry runs on two tricks: 25-year leases that put a lien on your house, and “1.99% APR” loans with a 30%+ dealer fee baked in. We don’t do either. Here’s every way you can actually pay for your install — pick the one that fits.

Cash
$0 interest

Best total cost

  • Zero interest, zero fees
  • Full $2,500 in rebates flow to you
  • Battery starts paying itself back month 1

Best for: savings sitting at less than 5% return.

HELOC
~7–9% APR

Best loan option

  • Tax-deductible interest (home improvement use)
  • Half the rate of industry solar loans
  • No dealer markup, no commission
  • 10–30 yr flexible terms

Best for: homeowners with equity. If you already have a HELOC, pull from it.

Affirm
0% APR

12 months · free money

  • Zero interest if paid in 12 months
  • Soft credit pull at application
  • No dealer fees, no rate markup

Best for: covering it with this year’s bonus or tax refund. Subject to approval.

BYOP direct loan
11–13% APR

Zero dealer fee

  • No dealer fee. Industry standard: 30–50% baked in.
  • 5–15 year terms
  • Rate matches your credit profile

Best for: no home equity yet, want predictable monthly payment.

Why we don’t push leases or industry “solar loans.”

Solar lease

You don’t own the battery. The salesperson takes a commission. The lease company puts a 20-year UCC lien on your house.

Industry “solar loan”

That 1.99% APR ad is a teaser. The 30–50% dealer fee folds into your loan principal silently. A $20K install becomes a $30K loan.

Our way

The price on this page is the price you pay. No dealer fee. No commission. No lien. Pick how you finance — your choice doesn’t change the install cost.

HELOC interest deduction depends on use; consult your tax advisor. Affirm and direct loan rates subject to credit approval.

FAQ

Common questions before quoting.

Hardware, labor, and paperwork — everything you need to flip the switch. The battery hardware (Tesla Powerwall 3, FranklinWH, SigEnergy, or whichever brand you pick), gateway / interconnection hardware, all install labor, permits, plan check, AHJ inspection, system commissioning, and app setup. The price you see is the price you pay. No add-ons billed later.

Backup-only battery installs run about 1 day on-site. Solar + battery bundles run 2–3 days depending on system size and roof complexity. Permitting and utility-interconnection scheduling adds 2–4 weeks before we break ground — we handle that paperwork in the background.

Most homes don’t need a panel upgrade for a single battery. We check your service entrance, main breaker rating, and available bus capacity at the site visit. If an upgrade is needed, we quote it transparently before you sign — no panel-upgrade surprises mid-install. Modern Powerwall 3 + meter collar interconnection avoids the upgrade entirely on most Utah homes.

Tesla Powerwall 3 (Tesla Certified Installer), FranklinWH aPower 2 (FranklinWH-trained), SigEnergy Stack, and EG4 for off-grid and rural cabin builds. All are Wattsmart-eligible except EG4, which is built for off-grid use. We’re commissioned by zero of these brands — we pick what fits your house and load profile.

Yes — this is one of our most common installs. We evaluate your current inverter, panel layout, and service entrance, then design the battery interconnect to match. Most retrofits avoid panel upgrades. Works whether you bought your solar from Sunrun, Sunpower, Sunnova, Vivint, Blue Raven, or any other installer.

The $500 Tesla rebate is filed through Tesla’s portal after install — you get a Visa card by email within ~8 weeks. The $2,000 Wattsmart rebate is paid by Rocky Mountain Power directly into your enrolled account. We file both applications for you. The money goes to your account, not BYOP Electric’s.

Heads up: the federal residential solar tax credit (the 30% ITC) expired December 31, 2025 and is no longer available for new residential installs. The current incentives are state and utility-level: $500 from Tesla’s Next Million Rebate plus $2,000 from Rocky Mountain Power’s Wattsmart Battery program. Both stack, both go to you — that’s $2,500 off your install. If anyone tells you the 30% credit is still on, they’re behind on the news.

Two things. (1) Four-year program enrollment. (2) RMP can dispatch a portion of your battery during peak grid events — never below your reserved backup. It happens a handful of times per year and your battery still backs up your home during grid outages. If you want zero RMP control over your battery, we’ll quote without Wattsmart enrolled — you’d just give up the $2,000 rebate.

Four ways to pay: cash (best total cost), HELOC (~7–9% APR, tax-deductible interest), Affirm 0% APR for 12 months (subject to approval), or BYOP direct loan at 11–13% APR with zero dealer fee. We don’t offer leases or industry “solar loans” with hidden 30–50% dealer fees baked into principal. If you want a referral to a fair-rate lender we’ve worked with, just ask in the text thread.

Engineer & Electrician owned and operated — you talk directly to the person who’ll design and install your system, not a sales rep. Published prices, no kitchen-table surprises.
