Without Solar: Projected San Diego Gas & Electric Bills
San Diego Gas & Electric rates have increased 71% (2015-2025, CPUC Public Advocates Office). If that trend continues, the average Ramona bill looks like this:
| Year | Est. Monthly Bill (no solar) | With Solar |
|---|---|---|
| 2026 (today) | $265/mo | ~$0/mo |
| 2031 (5 years) | $347/mo | ~$0/mo |
| 2036 (10 years) | $453/mo | ~$0/mo |
| 2041 (15 years) | $593/mo | ~$0/mo |
Projections use the 71% (2015-2025, CPUC Public Advocates Office) 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 San Diego 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.
