Brian's electricity bill in August used to be a guaranteed gut punch. Phoenix, Arizona. Three-bedroom house. Two kids. Two adults working from home. Central air conditioning running essentially all day from May through September.
His peak month: $312. Annual average: $218 per month. Annual electricity bill: $2,616.
Today, Brian's average monthly electricity bill is $34. That's 84% lower than it was. His solar system covers the vast majority of his consumption. On most spring and fall days, he's a net energy exporter, pushing power back to the grid and building credits that offset his summer air conditioning bills.
He's saving $2,208 per year. His payback period is under 8 years. And he has 17 more years of warranted system life after that.
This is his story, and it's worth reading if you're considering solar, because Brian also made two significant mistakes along the way that he wants other dads to avoid.
The Situation: A High Electricity Bill and a Lot of Sunshine
Brian is 44, an IT manager. He and his wife both work from home, which means the house is occupied and climate-controlled 24 hours a day, 7 days a week. Their two kids are in middle school.
Phoenix averages 299 sunny days per year, more than any other major U.S. city. It also has some of the highest residential cooling loads in the country. The combination of abundant sunshine and high electricity bills makes it one of the strongest markets for residential solar in the country.
Brian had thought about solar for about three years before actually pulling the trigger. "I kept seeing the ads, but I didn't trust them," he said. "The ads made it sound too easy. Free panels, no upfront cost, save money immediately. It felt like there had to be a catch."
He wasn't wrong to be skeptical. The "free panels" offers are leases and PPAs where you don't actually own the system and don't get the 30% federal tax credit. More on that in a moment.
The First Approach: A Lease That Almost Derailed Everything
The first solar company Brian talked to came through a door-to-door salesperson. The pitch: no money down, instant savings, installation within 60 days. The agreement: a 25-year solar lease at $95 per month with a 2.9% annual escalator.
Brian almost signed.
"The salesman was good. He showed me that $95 a month was less than my current average electricity bill. He made it sound like a no-brainer."
What the salesman did not explain clearly:
- Brian would not own the panels
- The solar company would claim the 30% Federal Investment Tax Credit, not Brian
- Over 25 years with the 2.9% annual escalator, Brian's lease payment would grow to $194 per month in year 25
- If he sold his house, the buyer would need to assume the lease or Brian would need to buy it out (the buyout price in year 10 was projected at $16,000)
Brian's brother-in-law, who had gone through a similar process in California, flagged the ITC issue. "He told me: ask them what happens to the tax credit. That's when I started asking better questions."
When Brian asked about the ITC, the salesperson confirmed: "That's used to offset our installation costs." Brian walked away.
The Second Approach: Getting the Right Information
Brian found TheSmartDad while researching solar guides online. He submitted his information and was connected with a licensed solar advisor in Arizona who knew APS (Arizona Public Service) territory inside and out.
The advisor's first move: pull Brian's 12 months of electricity bills to get his actual consumption data. Total annual usage: 18,400 kWh.
At APS's tiered rates, his average cost per kWh worked out to approximately 14.2 cents. His annual electricity cost: $2,613.
The advisor then ran a production analysis using satellite imagery of Brian's roof combined with local solar irradiance data and APS's net metering tariff.
Brian's roof had three sections:
- South-facing main section: ideal solar exposure
- West-facing section: good afternoon production
- North-facing: not useful
Available installation area on the south and west sections: enough for a 10.5 kW system.
The System Design and Quote
The advisor worked with two local Arizona-based installers he had vetted for quality and financial stability.
System designed: 10.5 kW, using 24 panels at 440W each, with SolarEdge power optimizers and inverter, and a standard roof mount on asphalt shingles. Quote 1 (Installer A): $36,750 before incentives Quote 2 (Installer B): $33,800 before incentivesThe advisor flagged the difference: Installer A was using slightly higher-tier panels with a longer manufacturer warranty. Installer B's panels carried a 25-year product warranty vs Installer A's 30-year. For Brian's situation, the advisor recommended Installer B as the better value, noting both installers were NABCEP-certified and had 9+ years in business in Arizona.
After the 30% Federal ITC:$33,800 x 0.30 = $10,140 credit
Net cost to Brian: $23,660
Brian also applied for APS's residential solar rebate program: $600.
Net cost after all incentives: $23,060.The Financing Decision
Brian and his wife discussed using cash vs a solar loan.
Cash option: they had $25,000 in a savings account earning 4.8% APY. Using it for solar would give them roughly a 12.5% annual return equivalent (based on savings per year vs system cost), significantly beating their savings account rate.
Solar loan option: a 12-year loan at 4.99% through a reputable solar lender. Monthly payment: $219. After the ITC credit was applied as a lump-sum payment in April following installation, the outstanding loan principal dropped to $16,500 and the monthly payment recalculated to $147.
The advisor modeled both:
- Cash: Net cost $23,060, savings of $2,613/year, payback 8.8 years. By year 20: cumulative savings approximately $52,000 above investment.
- Loan: No upfront cash needed, net monthly cash outflow after savings: approximately -$30/month initially (savings roughly offset payment), positive cash flow from year 2 onward as electricity rates rise.
Brian chose the loan. "We didn't want to deplete our savings account. The loan payment was nearly covered by our electricity savings from month one."
The Installation: What Actually Happened
Timeline from signed contract to Permission to Operate (PTO):
- Day 1: Contract signed
- Day 14: City of Phoenix permit filed
- Day 29: Permit approved
- Day 31: Installation began (took 2 days)
- Day 34: City inspection passed
- Day 68: APS Permission to Operate granted
"The wait for APS was the frustrating part," Brian said. "The panels were sitting on my roof, ready to go, for 34 days while we waited for utility approval. The installer was upfront about this, but it still felt like a long time."
On day 69, Brian turned the system on for the first time via the monitoring app.
The First Year: Real Numbers
Brian's system went live in April. Here is his first full 12 months of data.
System production: 18,840 kWh (slightly above the 18,300 kWh projected, due to a particularly sunny summer) Brian's home consumption: 17,900 kWh Net metered back to grid: 940 kWh (excess production fed to APS, credited at their net metering rate) Electricity bills by season:Spring (March-May): average bill $18/month (export credits building)
Summer (June-September): average bill $67/month (high AC load, using stored credits)
Fall (October-November): average bill $12/month
Winter (December-February): average bill $9/month
Annual electricity bill: $408 Previous annual electricity bill: $2,613 First-year savings: $2,205 Annual loan payment: $1,764 (after ITC lump-sum applied to principal) Net first-year benefit: $2,205 savings minus $1,764 loan payment = $441 in year oneThat net benefit will grow every year as electricity rates increase and the loan payment stays fixed.
What Brian Says About the 70% Reduction Claim
"When people hear '70% lower bill,' some assume I'm exaggerating. But my bill went from $218 average to $34 average. That's 84% lower on average. In the summer months, it's less dramatic because my AC is working overtime. In spring and fall, my bill is basically just the APS connection fee."
Brian's $34 average monthly bill consists primarily of APS's basic service charge, which is mandatory regardless of consumption. In Arizona, APS charges a fixed $20 monthly service fee for staying connected to the grid. Brian is using the grid as his "backup battery" under net metering, drawing power at night and during peak demand periods, and exporting excess solar production during the day.
Two Things Brian Wishes He'd Known Earlier
Thing 1: The lease trap is real, and it targets people in high-bill areas.Door-to-door solar sales are disproportionately concentrated in high-electricity-cost markets like Arizona, California, and Florida. Homeowners in these areas are the most motivated to find savings, which makes them the most receptive to a pitch that leads with "no money down." Brian estimates he came within one conversation of signing a lease that would have cost him $17,000 more than his loan over 25 years.
"If I had signed that lease, I'd have locked in 25 years of escalating payments on a system I don't own. And I'd have given up the tax credit. That's an enormous cost for the convenience of no upfront payment."
Thing 2: Net metering terms change, and you should lock in when terms are favorable.At the time Brian installed, APS's net metering credit rate was 9.86 cents per kWh for excess production. This is lower than the retail rate he pays for consumption (about 14 cents), but still significant. APS has made no changes to its net metering policy since Brian's installation, but he notes: "My installer told me that net metering terms have been modified in some other states, and there's no guarantee they won't change here. Installing sooner rather than later locks me into current APS policy during the grandfathering period."
In most states, when a utility modifies net metering terms, existing solar customers are grandfathered under their original terms for a set period (typically 10 to 20 years). Installing under favorable terms protects you.
What Brian Would Tell Any Dad Considering Solar
"First: don't talk to anyone who knocks on your door. Get multiple quotes from licensed local installers. The guy at the door is almost always pitching a lease, and leases are almost never the right financial choice for homeowners with normal tax liability.
Second: get your 12 months of electricity bills before any conversation. The first thing a good advisor needs is your actual consumption data. Everything else flows from that.
Third: ask every company you talk to: 'Do I own the system, and who gets the federal tax credit?' If the answer to either question isn't clearly in your favor, walk away."
Your Home. Your Numbers.
Brian's $2,208 annual savings are Brian's numbers. Phoenix's solar resource, APS's rates, and his specific home's consumption make his case particularly strong.
Your home has different sun hours, different utility rates, different consumption patterns, and a different roof configuration. The only way to know your actual savings potential is to have it analyzed properly.

Postscript: One Year Later
We checked in with Brian 18 months after his system went live.
His system is producing as projected. He added a Tesla Powerwall home battery 8 months after the solar installation, which cost $10,500 after the ITC (the battery qualifies for the 30% credit separately). The battery provides 4 to 6 hours of home backup during power outages, which APS has experienced three times in the past year due to weather events.
"The battery was an additional investment. It didn't dramatically change my electricity savings because I already had net metering. But the backup power has paid for itself twice in peace of mind alone. Phoenix gets summer monsoons, and losing power for 8 hours in August with two kids is miserable."
His total solar investment to date: $23,060 (system) + $10,500 (battery) = $33,560. His annual electricity savings have grown to $2,290 as APS rates increased in 2026. His payback on the full investment is projected at approximately 14.6 years, with a 25+ year asset life on the system components.
"I'm a data person. I track everything in a spreadsheet. Every month, the numbers get a little better. I wish I'd done this 3 years earlier."
Solar savings, system production, payback periods, and incentive availability vary significantly by location, home configuration, utility territory, and financial structure. The 30% Federal Investment Tax Credit applies to qualifying owned solar installations through 2032 as of this writing; verify current terms with a tax professional.
