Ever gotten your solar bill and thought: wait, why isn't this zero?
You're not alone. It's one of the most common questions we hear, and honestly, it points to a gap in how solar is sold.
Here's the truth: solar reduces your bill significantly, but it doesn't eliminate every line item. Your electric bill has multiple components, and solar only offsets some of them.
The parts solar DOES offset:
Your energy charges -- the cost per kilowatt-hour you actually consume. This is where the real savings live, and a well-sized system can cut this by 60-90% annually.
The parts solar DOESN'T offset:
Fixed fees (basic service charge, meter fees, grid connection) -- typically $10-30/month no matter what
Non-Bypassable Charges (NBCs) in California -- charged on every kWh you pull from the grid, even if you're a net producer
Minimum monthly charges that some utilities require regardless of usage
Why your savings might feel lower than expected:
Your panels produce the most power around noon. Your household likely uses the most power around 7pm, when cooking dinner, running the AC, charging devices. Under Time-of-Use rates, you're buying expensive evening power and selling cheaper mid-day power back to the grid. That timing gap matters.
Also, if you added an EV, a pool, or started working from home after going solar, your usage went up. And that can mask real savings that are absolutely still there.
If you're on NEM 3.0 in California, the rate you receive for excess power exported to the grid is significantly lower than what you pay to import it. That's a different ballgame than older NEM versions.
The honest benchmark:
If your system is producing as projected and your annual energy charges are down 60-90%, your solar is working, even if the bill isn't literally zero.
