Why homeowners add solar battery storage in San Diego

Most people don’t think about batteries until an outage hits or SDG&E rates jump again. Solar alone shuts off during outages for safety reasons, which surprises a lot of homeowners. A battery changes that. It keeps lights on, refrigerators running, and Wi-Fi working when the grid drops.

At McKay Roofing and Solar, we see battery installs tied to peace of mind more than anything. People want backup without relying on generators. Solar battery storage makes that possible, especially in areas that see frequent outages or unstable service.

What solar battery installation includes

Solar battery installation starts with evaluating your existing solar system, electrical panel, and available space. Not every home is set up the same, and battery placement matters for safety and performance.

The install includes mounting the battery, connecting it to your solar system, configuring the inverter, and setting up monitoring so you can see how power flows. It’s not just adding hardware. It’s integrating storage properly with your solar installation so everything works together.

How long solar battery installation takes

Most residential solar battery installs are completed in one to two days once permits and equipment are ready. The timeline depends on panel upgrades, inverter compatibility, and system layout.

If electrical work or roofing adjustments are needed, those are handled first. Because we handle both roofing and solar, everything stays on one schedule instead of waiting on multiple contractors to coordinate.

Common reasons batteries get added after solar

A lot of battery installs happen years after solar panels go up. Homeowners realize net metering rules changed, rates increased, or outages became more common. What worked before doesn’t work the same anymore.

We also install batteries when people upgrade older systems or replace equipment. Battery storage helps maximize what the system produces instead of sending excess power back to the grid at lower value.

Solar battery installation vs generator backup

Generators still work, but they come with fuel, noise, and maintenance. Solar batteries are quiet and automatic. When the power goes out, they switch over without anyone doing anything.

Battery storage also works daily, not just during outages. It stores energy for peak hours and pairs naturally with solar panel replacement or system upgrades when panels are already being worked on.

Battery systems and roof considerations

Battery installs don’t usually affect the roof directly, but solar wiring and penetrations still matter. Poor past installs can cause issues when batteries are added later.

That’s why battery installs are handled as part of a full Solar Energy Company San Diego approach, not just electrical work. Everything from the roof to the inverter gets checked before final setup.
