Without Solar: Projected Pacific Gas & Electric Bills
Pacific Gas & Electric rates have increased 83% (2014-2024). If that trend continues, the average Elk Grove bill looks like this:

|---|---|---|
| 2026 (today) | $235/mo | ~$0/mo |

The Compounding Advantage
The payback period calculation above uses today's rates. In reality, as Pacific Gas & Electric 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.
