Without Solar: Projected Arizona Public Service Bills
Arizona Public Service rates have increased 35% (2014-2024). If that trend continues, the average Yuma bill looks like this:
| Year | Est. Monthly Bill (no solar) | With Solar |
|---|---|---|
| 2026 (today) | $185/mo | ~$45/mo |
| 2031 (5 years) | $215/mo | ~$45/mo |
| 2036 (10 years) | $250/mo | ~$45/mo |
| 2041 (15 years) | $290/mo | ~$45/mo |
Projections use the 35% (2014-2024) 10-year CAGR as a straight-line estimate. Actual rate changes vary. Solar bill estimates assume fixed system output.
The Compounding Advantage
The payback period calculation above uses today's rates. In reality, as Arizona Public Service rates rise each year, your solar savings grow too — because every kWh your panels produce is worth more. This means the effective payback period is typically shorter than the static calculation suggests, and the 25-year savings figure grows significantly with each rate increase.
