Turning Arizona Sunshine into Long-Term Savings
Arizona is known for its bright sun and clear skies, making it one of the best places in the U.S. for solar energy. Many families are switching to solar to save on their electricity bills and help the planet. But before you decide to go solar, it’s important to understand how much money you could save in the long run.
This easy guide will help you figure out how to calculate the real cost savings of solar panels in Arizona. We’ll walk through the key steps, give helpful examples, and break everything down in a way that’s simple to follow.
Why Solar in Arizona Is a Smart Choice?
Arizona gets tons of sunshine over 300 sunny days a year! That means solar panels can produce a lot of electricity for your home. When you make your own power, you don’t have to buy as much from the electric company. That can lead to big savings over time. Plus, electricity prices often go up each year, but with solar, your costs stay mostly the same.
To see the full picture of how much you’ll save, you need to look at a few key things. Let’s explore them step by step.
How to Figure Out Your Long-Term Solar Savings
1. Know How Much Electricity You Use Each Year
Start by looking at your electricity bills from the past 12 months. Find your average monthly usage in kilowatt-hours (kWh), then multiply that by 12 to get your yearly total. This number helps you decide what size solar system you need.
2. Find the Right Size Solar System
A solar installer can suggest a system that matches your energy needs. They’ll look at your yearly usage, roof space, and budget. The size is measured in kilowatts (kW). A bigger system makes more electricity but also costs more.
3. Estimate How Much Power Your Panels Will Make
Your system’s energy output depends on:
- Sunlight in Your Area: Arizona has great solar potential, but it can vary by city.
- Panel Efficiency: Better panels make more energy.
- Panel Angle and Direction: South-facing panels usually work best.
- Shade: Trees or buildings that block the sun can lower output.
Good solar companies use software to predict how much power your panels will produce. Ask to see these estimates in their proposal.
4. Figure Out How Much You’ll Save Each Year
Multiply your expected solar energy production (in kWh) by the amount your utility charges for electricity. That’s your estimated yearly savings.
Example Formula:
10,000 kWh x $0.12 per kWh = $1,200/year in savings
Don’t forget to check if your utility gives credit for extra power you send to the grid this is called net metering.
5. Subtract Incentives from the Solar Cost
Solar panels can be expensive, but you can reduce the cost with:
- Federal Tax Credit: You can get back 30% of the total cost on your taxes.
- Local Utility Rebates: Some Arizona utility companies (like SRP or TEP) may offer money back for going solar.
Take these savings off the total system cost to see your net investment.
6. Think About the Lifespan of Your Solar System
Most solar panels last 25 years or more. They do lose a tiny bit of power each year (usually about 0.5%). This is called degradation. Make sure you include that in your long-term savings plan.
7. Add Up Your Total Savings Over 25+ Years
Now, take your yearly savings and multiply by the number of years your panels will last. Remember to adjust for:
- Energy Production Decline
- Electricity Price Increases (2-3% yearly)
Over time, the rising cost of electricity means your solar savings can grow even more than expected.
8. Plan for Minor Maintenance Costs
Solar systems don’t need much upkeep, but setting aside $100–$200 per year for cleaning or small repairs is smart. This keeps your savings estimate realistic.
9. Figure Out Your Payback Time and ROI
- Payback Period: Divide your net cost by your yearly savings to see how long it takes to earn back your investment.
- ROI (Return on Investment): Add up all your savings over the system’s life, subtract the cost, and turn it into a percentage.
Why Arizona’s Net Metering Rules Matter
If your system makes more power than you use, you can send it back to the electric grid. Some utilities give you credit for this power. But the rate they pay varies. Some give you the full price you pay for power (retail rate), while others give you a lower amount (called avoided cost). This affects your savings, so it’s good to ask your utility how their net metering works.
Example: Solar Savings in Arizona
Let’s say you buy a 6 kW system for $21,000. After the 30% tax credit, your net cost is $14,700.
- Estimated Output: 10,000 kWh per year
- Electricity Cost: $0.12 per kWh
- Annual Savings: $1,200
- Panel Lifespan: 25 years
- Degradation Rate: 0.5% per year
- Electricity Inflation: 2% per year
- Maintenance: $150 per year
With these numbers, your system could save you well over $30,000 across 25 years.
Benefits of Knowing Your Solar Savings

| Annual Electricity Use | Helps size your system and estimate savings |
| Solar System Size (kW) | Bigger systems generate more electricity |
| Annual Production (kWh) | Shows how much power your panels will make each year |
| Electricity Rate ($/kWh) | Higher rates = more savings per unit of power |
| Net System Cost (after incentives) | Determines your upfront cost |
| Panel Lifespan & Degradation | Shows how long your panels will work and how much output they’ll lose over time |
| Rate Inflation | Helps estimate how your savings grow over time |
| Maintenance Costs | Small yearly expenses that affect your final savings |
| Net Metering Rules | Affects how much you earn from extra solar power sent back to the grid |
