QUICK ANSWERS
Frequently asked questions
Start with the short answer, then use the guide library above for the full context.
How much can solar save a California homeowner?
Savings depend on your current rate plan, electricity use, roof production, system price, payment method, and how energy is used or exported under NEM 3.0. A personalized estimate is more useful than a statewide average.
Do I need a battery with solar?
Not every home needs one. A battery may be useful for outage backup, shifting energy into expensive evening hours, or increasing self-consumption. Its value depends on your goals and utility rate structure.
Will I still receive an electric bill?
Usually, yes. Utility accounts may still include fixed charges, grid electricity used at night or during low production, and annual or monthly settlement adjustments.
What is California NEM 3.0?
NEM 3.0 is California's net billing framework for many new solar customers. Exported electricity is generally credited differently from the retail rate, making system design and self-consumption more important.
How long does a solar installation take?
The physical installation may take only a few days, but design, permitting, inspection, and utility approval can make the full process last several weeks or longer.
Does a new California ADU require solar?
Some newly constructed ADUs are subject to California energy-code solar requirements, while exceptions may apply. Confirm the requirements early with the designer and local permitting authority.
Is solar worth it in California?
It can be, but the answer is property-specific. Electricity use, roof condition, system cost, payment terms, utility territory, moving plans, and expected payback should all be considered together.
A PERSONAL DECISION
Still have questions?
Every home is different. Your electricity usage, roof condition, utility company, and future plans all affect whether solar is the right investment. If you'd like personalized guidance, talk with an experienced California solar advisor before making your decision.
