Solar FAQ's
Serving the Greater Sacramento Area since 1995
In Rancho Cordova, Sacramento, and all of California, homeowners have unique concerns about Sacramento solar and battery storage due to NEM 3.0, wildfire-related power outages, high utility rates, and state incentives. Here are the most common questions California homeowners ask when considering solar and battery installation:
General Solar Questions (California-Specific)
Under NEM 3.0, homeowners receive lower credits for excess energy sent to the grid (75% less than before). This makes battery storage more valuable since it lets you store and use your own power instead of selling it at low rates.
Will I still get utility bill charges after installing solar?
Yes. Even with solar, you’ll pay a monthly utility connection fee (typically $10- $20) plus any extra energy used beyond your system’s production.
How much will solar lower my PG&SMUD bill?
It depends on system size, energy use, and battery storage. Many homeowners reduce bills by 60-100% by shifting usage to solar and stored power.
What are the best financing options for solar in California?
Most homeowners choose solar loans, cash purchases, or PACE financing. Leases and PPAs are less popular under NEM 3.0 since owning solar is now more beneficial.
Does California offer any rebates for solar?
The 30% federal tax credit applies, but state rebates are mostly for batteries (e.g., SGIP battery rebate for backup power).
What is the payback period for solar in California?
With NEM 3.0, payback periods are now 7-10 years with a battery and 5-8 years without one, depending on utility rates and system size.
How long does it take to install solar in California?
The actual install takes 1-3 days, but permitting and approvals (especially in California) can take 4-10 weeks due to city and utility review processes.
Do I need permission from my HOA to install solar?
No, thanks to California’s Solar Rights Act (HOAs cannot prohibit solar but may have guidelines on placement).
What happens if I sell my home after installing solar?
Solar adds value to your home and can help it sell faster and for more money. If financed, the loan must be paid off or transferred to the buyer.
Can I install solar if I’m in a wildfire zone?
Yes, but some insurance companies have increased rates or refused coverage for homes with solar in high-risk areas.
Battery Storage Questions (California-Specific)
Yes, a battery is highly recommended to store excess solar energy and avoid low export rates.
How will a battery help during a power outage?
A battery provides backup power to keep essential loads (fridge, lights, WiFi, etc.) running when the grid is down.
Does California offer any rebates for battery storage?
Yes! The Self-Generation Incentive Program (SGIP) offers rebates based on income and fire risk zones.
Can a battery power my whole home?
A single battery typically powers essential circuits. Whole-home backup usually requires multiple batteries.
How long does a battery last during an outage?
A 13.5 kWh Battery can power essential loads for 10-24 hours, depending on energy use.
Does California offer any rebates for battery storage?
Yes! The Self-Generation Incentive Program (SGIP) offers rebates based on income and fire risk zones.
Can a battery power my whole home?
A single battery typically powers essential circuits. Whole-home backup usually requires multiple batteries.
How long does a battery last during an outage?
A 13.5 kWh Battery can power essential loads for 10-24 hours, depending on energy use.
Can I add a battery to my existing solar system?
Yes, but some older systems may need an inverter upgrade to be battery-compatible.
What is the lifespan of a solar battery?
Most lithium-ion batteries last 10-15 years, with warranties covering 10 years or 6,000 charge cycles.
Do I need multiple batteries?
If you want whole-home backup, yes. Otherwise, a single battery can power essentials like a fridge, WiFi, lights, and outlets.
How much does a battery cost in California?
Batteries typically cost $10,000-$15,000 before incentives. With SGIP rebates and tax credits, the cost can be significantly reduced.
How do I maximize savings with solar + battery under NEM 3.0?
Use a Time-of-Use (TOU) rate plan, store excess solar power in a battery, and use stored power during peak rate hours (eg 4-9 PM).
California Homeowners’ Key Takeaways:
- Batteries are more important than ever under NEM 3.0
- SGIP rebates make batteries more affordable
- Solar alone still saves money, but adding a battery maximizes savings
- Power outages are common, and batteries provide backup power
- Permitting and interconnection in California take longer than in other states
