If I go solar, will my electric bill actually go away completely?
It's the dream that draws most San Diego homeowners to solar: a zero electric bill. The reality is usually pretty close—but "usually" doesn't always mean "always." Here's what you actually need to know.
Most People See Huge Reductions
The good news first: most homeowners who go solar do see dramatic cuts to their electric bills. When your solar panels generate power during the day, you're using that instead of buying electricity from the grid. Over the course of a year, that adds up to real money.
In San Diego, where we get plenty of sunshine, the potential is especially strong. If you size your system right and your roof gets good sun exposure, you could offset 80–100% of your annual electricity use.
But a Completely Zero Bill Isn't Guaranteed
Here's where it gets honest: a truly zero bill depends on three main factors.
Your energy usage. How much electricity do you actually use? A family that runs the AC all summer, charges an electric vehicle, and heats water with electricity will need a bigger system than someone with modest consumption. If your usage is high, you might need a larger solar array than your roof can accommodate.
Your available roof space. Not every home has a south-facing roof with no shade. Trees, skylights, and roof shape all matter. The more usable space you have, the more panels you can install, and the more power you generate.
Your system size. This is the variable you can control. You choose how many panels to install. A larger system generates more power but also costs more upfront. A smaller system might be cheaper but won't cover 100% of your needs.
About Those Grid Connection Fees
Even if your solar panels generate all the electricity you use, most homeowners still see a small monthly bill. San Diego utilities charge a grid connection fee—a base charge just for being connected to the electrical system. It's usually modest, but it's rarely zero.
This fee exists whether you use the grid or not. Think of it like a basic service charge.
Some homeowners also keep a grid connection for backup power on cloudy days or at night, which can factor into their overall bill structure.
Getting Real Numbers for Your Home
The only way to know what your actual bill could be is to assess *your specific situation*. Every home is different.
Apollo Home Power can evaluate your roof's sun exposure, analyze your past electricity usage, and model out what a solar system would actually produce for you. That assessment gives you real numbers—not generic promises. You'll know what to expect before you commit.
It's the difference between hoping your bill goes away and knowing whether it actually will.
Most San Diego homeowners do end up with bills that are nearly zero or dramatically reduced. But the only way to know for sure is to get a real look at your home, your roof, and your habits.
