A 7kW system in Sacramento costs approximately $21,000 at $3/watt. With annual savings of $1,968 (based on SMUD (Sacramento Municipal Utility District)'s 13.7¢/21.9¢ rate tiers), the break-even point is approximately 10.7 years.

Without Solar: Projected SMUD (Sacramento Municipal Utility District) Bills

SMUD (Sacramento Municipal Utility District) rates have increased 15% (2021-2023), about 3% per year approved through 2027. If that trend continues, the average Sacramento bill looks like this:

Projections use the 15% (2021-2023), about 3% per year approved through 2027 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 SMUD (Sacramento Municipal Utility District) 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.
