Solar Power 101: How Solar + Battery Storage Can Power Your Home Day & Night

Solar power can be a great way to lower your energy bills, reduce reliance on fossil fuels, and support a more sustainable future for our community.  

When paired with a home battery, solar energy becomes even more powerful. A battery allows you to use the energy your panels generate during the day at night, during cloudy weather, or even in a power outage. That means more savings, reliability, and peace of mind that comes with having control over your own power.

How solar panels work

The science behind solar panels may sound complicated, but the process is actually very straightforward: 

    • Sunlight hits the panels: Each panel is made of photovoltaic (PV) cells that absorb sunlight.

    • Electricity is generated: The PV cells convert sunlight into direct current (DC) electricity.

    • Power is available for your home: An inverter changes DC into alternating current (AC), which is the type of electricity your home runs on. 

 

With the right system, your panels can cover much of your home’s electricity needs! 

Why add battery storage? 

Solar panels only produce electricity during daylight hours. A home battery makes sure you can use that power whenever you need it.

    • Store power for later: Capture excess energy during the day and use it at night.

    • Stay powered during an outage: Keep essentials running, such as lights, Wi-Fi, and refrigerators.

    • Cut costs further: Avoid paying high rates during “peak hours” by using your own stored solar energy instead.

    • Boost energy independence: Rely less on the grid and more on your own clean energy.

Why homeowners shouldn’t wait

For many homeowners, solar and battery systems offer greater control over their energy use and protection from rising electricity rates. Solar panels can also add value to your property—studies show that homes with solar systems often sell for more due to long-term energy savings and reliability. 

You can also find support and guidance for existing systems through PCE’s Solar + Battery Owners Resources, which include information on energy credits, billing, and maximizing your system’s performance. 

In short: solar panels and batteries can be a meaningful investment in your home and community, delivering reliable power and lasting value for years to come.

Yes! While solar panels produce the most electricity in direct sunlight, they still generate energy on cloudy days—just at a lower level. Adding a battery helps smooth things out by storing extra power from sunnier hours.

Even if your area gets frequent cloudy days, a qualified installer can design your system to match your local weather patterns and energy needs.

How long do solar panels & batteries last? 

Solar panels are built to last 25–30 years, and they often keep producing electricity well beyond their warranty period. Most batteries have a useful life of about 10–15 years and are designed for reliable, everyday use.

Together, they provide long-term stability, helping you lock in lower energy costs year after year. Plus, knowing your system is designed to last for decades makes going solar a smart investment for both your home and your future.
