You’ve probably heard that solar can save you thousands. But what does that really mean? How much money can you expect to keep in your pocket each month, each year, or over the lifetime of your system? And eventually is solar worth it?
Let’s break it all down – using real-world math and examples – so you can see what going solar could look like for your home.
How solar saves you money
The primary way solar saves you money is by reducing or eliminating your electricity bill. When your system generates power, your home uses that energy instead of pulling it from the grid. Any electricity you don’t use can be sent back through net metering, earning you credits and increasing your long-term savings.
If you want to estimate solar savings for your home, the biggest factor is how much grid electricity your system can replace over time.
What impacts your solar savings?
A few key variables shape your overall solar savings estimate:
-
Electricity rates – Higher utility costs create higher savings potential.
-
Energy usage – The more you use, the more you offset.
-
Sun exposure and climate – More sunlight means more generation.
-
System size and design – Proper sizing maximizes savings.
-
Local incentives and net metering – These can significantly boost ROI.
-
Financing method – Cash offers the highest lifetime return, but loans still help you save with solar.
Real example: California homeowner
-
Monthly bill before solar: $250
-
System size: 7.5 kW
-
Cost after incentives: $18,000
-
Monthly solar production value: ~$220 in avoided utility charges
Annual savings: ~$2,640
25-year savings: ~$66,000+
Payback period: ~7 years
Real example: Arizona homeowner
- Monthly bill before solar: $180
- System size: 6 kW
- Cost after incentives: $14,500
- Monthly solar value: ~$160
Annual savings: ~$1,920
25-year savings: ~$48,000
Payback period: ~7.5 years
Real example: Texas homeowner (with time-of-use pricing)
- Monthly bill before solar: $220
- System with battery backup: 8.2 kW
- Cost after incentives: $22,500
- Monthly solar savings: $200-$230, depending on usage timing
Annual savings: $2,400-$2,760
25-year savings: $60,000-$69,000
What about small homes or low usage?
Even homes with smaller systems and lower usage can benefit. If your average bill is $80, a solar system that covers 80 percent of your usage could still save $700-$1,000 per year.
Bonus savings: future-proofing your energy bills
One of the biggest overlooked savings from solar is protection against rising electricity costs. Utilities raise rates by an average of 2.5 to 5 percent annually. Solar lets you lock in today’s rates for decades.
Other financial benefits:
- 30% federal tax credit (2025)
- Increased home resale value
- Potential to add battery storage and boost self-consumption
