The honest short answer
If your priority is silent operation, integration with solar, and short-to-medium outages (up to about 24 hours): go solar + battery (Tesla Powerwall 3 or Enphase IQ Battery 5P).
If your priority is whole-home power during multi-day outages, lowest cost per watt of backup, and you don’t already have solar: go Generac standby generator.
If you want both (and a lot of Cedar City homeowners eventually do): install solar + battery first, then add a small Generac as the deep-outage failsafe. Most expensive but most resilient.
Cedar City-specific reality: the grid is reliable on the north side of town. Brian Head and Duck Creek cabin owners face 4-20 hour winter outages multiple times per year. The right backup choice differs sharply based on where the property is.
We’re Fowler Electric. Utah license #12129347-5501. We’re an authorized Generac dealer AND a licensed solar/battery installer (Enphase, Tesla Powerwall, EG4). We install all of these regularly. This is the honest comparison most contractors avoid because they only sell one.
What you’re actually comparing
This isn’t a like-for-like comparison. Each system does different things.
Solar + battery backup (Tesla Powerwall 3, Enphase IQ Battery 5P, EG4)
How it works: Solar panels charge a battery during the day. When the grid drops, the battery powers your home from stored energy. Solar continues charging the battery during daylight, extending runtime indefinitely on sunny days.
Best for: Frequent short outages (under 6 hours), grid-tied homes with existing or planned solar, homeowners who want silent operation, families with high evening usage who already wanted solar anyway.
Limitations: Battery alone (without solar charging) typically runs 6-24 hours. Winter outages with cloudy weather can drain the battery before sun recharges it. Cold weather reduces battery capacity 20-30%.
Generac standby generator
How it works: A propane (or natural gas) tank fuels an automatic generator. The grid drops, the generator detects it in 2-10 seconds, starts, transfers home circuits to generator power, and runs as long as fuel lasts.
Best for: Multi-day outages, homes without solar, cabins in deep-outage zones (Brian Head, Duck Creek), homeowners who want set-and-forget reliability. See our full Generac pricing guide.
Limitations: Loud (about 65-70 dB at 7 feet for air-cooled units). Requires a propane tank install (separate cost). Needs annual maintenance.
Hybrid: solar + battery + small generator
How it works: The battery covers normal outages (hours to a day). The generator kicks in only during extended outages when the battery is depleted. Best of both worlds.
Best for: Cabin owners, off-grid-curious homeowners, anyone who wants belt-and-suspenders resilience.
Limitations: Most expensive. Most complex install. Most maintenance points.
Real Southern Utah 2026 pricing
Solar + battery only
| System | Runtime alone | Pre-incentive cost |
|---|---|---|
| 8 kW solar + 1 Tesla Powerwall 3 (13.5 kWh) | Essentials 12-18 hrs | $35,000 – $45,000 |
| 10 kW solar + 2 Tesla Powerwall 3 (27 kWh) | Whole-home 24-36 hrs | $48,000 – $62,000 |

| 12 kW solar + 3 Enphase IQ Battery 5P (15 kWh) | Larger home essentials | $48,000 – $58,000 |
The federal solar tax credit (30% through 2032) reduces these by roughly $10,500-$18,500. Net cost after the federal credit: typically $25,000-$45,000 for a meaningful solar + battery system.
Generac generator only
| System | Runtime per propane tank | Turnkey cost |
|---|---|---|
| 14 kW Generac + 250-gal propane tank | ~4 days at full load | $11,500 – $17,000 |
| 22 kW Generac + 500-gal propane tank | ~8-10 days | $14,500 – $21,000 |
| 26 kW Generac liquid-cooled + 1,000-gal | 16-20 days | $19,000 – $28,000 |
Generator pricing includes electrical install, ATS, permit, RMP coordination, and commissioning. Propane work is separate but included in the totals above.
Hybrid
| System | Cost |
|---|---|
| 8 kW solar + 1 Powerwall 3 + 14 kW Generac | $46,500 – $62,000 (pre-incentive) |
| 10 kW solar + 2 Powerwall 3 + 22 kW Generac | $62,500 – $83,000 (pre-incentive) |
After the federal solar credit: typically $33,000-$70,000.
What Cedar City specifically faces
Grid reliability by neighborhood
Reliable (1-3 hours of outage per year): most of Cedar City proper (Downtown, Westview, College Hills, Cross Hollow), Enoch, St. George core, Hurricane and Washington core.
Less reliable (4-12 hours per year): outskirts of Cedar City (Cedar Highlands, Cedar Knolls south), Parowan, Kanarraville, rural Iron County properties.
Frequently disrupted (4-30 hours per year): Brian Head Town, Duck Creek Village, the Cedar Breaks area, any cabin on a long radial feeder, and the Highway 14 corridor.
Choose backup based on your outage exposure. Cedar City core homeowners: a Powerwall covers virtually every outage they’ll experience. Brian Head cabin owners: a generator is non-negotiable; battery alone won’t get them through a 3-day winter storm.
Solar production by season
Southern Utah is one of the best solar regions in the US: summer produces about 6.5-7.0 kWh per kW per day, spring/fall about 5.0-5.5, and winter about 3.5-4.0. Winter production is still strong by US standards, but during snowstorm events you can lose 1-3 days of meaningful solar yield. This matters for battery sizing.
Propane availability
Multiple propane suppliers serve Cedar City and the cabin communities. Tank install for new generator owners is straightforward: $1,500-$5,000 depending on tank size and burial. Refills run $250-$800 per fill.
Lifestyle factors that decide the right choice
How long do your outages typically last? Under 4 hours: either works. 4-24 hours: battery still works for most usage if sized right; a generator runs the whole home without thought. Over 24 hours: generator-only or hybrid.
Do you already have solar (or want it anyway)? Already have solar: adding a battery is the natural extension ($12,500-$16,500 for a Powerwall 3). No interest in solar: skip the battery entirely; a generator is cheaper and runs longer. Curious: get an honest solar quote. The 30% federal credit runs through 2032; payback is 8-12 years in Southern Utah.
Noise tolerance. Solar + battery: silent. Generac air-cooled: 65-70 dB at 7 feet (louder than a dishwasher, quieter than a vacuum). Generac liquid-cooled: 60-65 dB.
Maintenance willingness. Solar + battery: minimal (annual inspection, $200-$400). Generator: annual maintenance visit $200-$350, oil changes, weekly self-exercise cycles, and an eventual starter battery replacement around year 5.
Long-term cost (10 years, average home). Solar + battery (8 kW + 1 Powerwall): roughly $34,000 all-in but offset by about $25,000 in electric bill savings, for a net of about $9,000. Generac 14 kW: about $21,500 all-in. Hybrid: about $30,500 net. Solar + battery has the lowest true 10-year cost if bill savings count; the generator has the lowest install cost; hybrid is the most resilient.
What we recommend by property type
Cedar City core home (1,800-2,500 sq ft, reliable grid): 8 kW solar + 1 Tesla Powerwall 3. Net about $25,000 after credit. Covers essentially every outage you’ll experience and eliminates most of your electric bill. Silent.
Cedar City home, no interest in solar: 14 kW Generac air-cooled + 250-gal propane. About $13,000 turnkey + $2,000 propane tank.
Brian Head or Duck Creek cabin (weekend/seasonal): 14 kW Generac with critical-loads ATS + 500-gal propane. Battery alone WILL drain during multi-day cabin outages. A generator is mandatory for freeze protection. See our cabin electrical guide.
Brian Head full-time residence: hybrid. 10 kW solar + 2 Powerwall 3 + 22 kW Generac. About $70,000 pre-incentive, $55,000 net.
Off-grid-curious / homestead: 12 kW solar + 30 kWh battery + 22 kW Generac. Full off-grid capable in normal months, generator-supplemented in winter.

Frequently Asked Questions
Can I add a battery to my existing solar later?
Yes, in most cases. Existing systems with Enphase microinverters are easier to retrofit than string-inverter systems. We do battery retrofits regularly. Cost: the same as a new battery install ($12,500-$16,500 for a Powerwall 3) plus a small reconfiguration fee.
Does Generac integrate with solar?
Yes. Some configurations let the generator charge the battery during deep outages, extending battery runtime indefinitely. This requires a specific transfer switch and inverter configuration. We design these regularly for cabin owners.
Tesla Powerwall vs Enphase Battery: which is better?
Tesla Powerwall 3: bigger capacity per unit (13.5 kWh), integrated inverter, slightly cheaper per kWh. Enphase IQ Battery 5P: modular (5 kWh per unit, stack to your need) and pairs naturally with Enphase microinverters. Either is excellent. We install both.
Will solar work on a Brian Head cabin?
Yes, with caveats. Winter sunshine is real (about 3.5-4 kWh per kW per day in December) but snowstorms can reduce that significantly. Battery-only at 9,800 feet during a 3-day storm is risky. We recommend pairing with a generator for cabin installs.
Can I get federal tax credits for both?
Solar + battery: yes, the 30% federal credit runs through 2032 and covers batteries paired with solar (battery-only retrofits also qualify under the Inflation Reduction Act updates). Generator: no federal tax credit. Generac is not solar.
How long does the install take?
Solar + battery: 3-6 weeks from contract (permit, materials, RMP interconnect, install). Generator only: 3-5 weeks (propane tank coordination is the variable). Hybrid: 6-10 weeks.
What about Rocky Mountain Power net metering?
Solar systems require an RMP net metering interconnect; we handle the full application. RMP currently credits exported solar at a less-than-retail rate, so consuming your own power plus battery storage is more valuable than exporting. A battery makes solar payback faster, not slower.
