Solar Solutions in Los Altos, CA

At Citadel Roofing & Solar, we make going solar easy. With decades of experience and thousands of installations across California, we’ve helped families in Los Altos lower their utility bills, add backup protection, and take advantage of some of the strongest solar incentives in the country.

Why Solar Makes Sense in Los Altos

Between high utility rates and an ideal solar climate, there are plenty of reasons why Los Altos homeowners are making the switch.

Here’s why solar is a natural fit:

Put California’s Sunshine to Work

Los Altos gets about 263 sunny days each year, compared to the national average of 205.

Lower Your Monthly Bills

PG&E has some of the highest electricity rates in the state. Solar helps you take control and avoid the price hikes.

Save More With Incentives

You can claim a 30% federal tax credit when you install solar at home.

Power Through Outages

Battery storage gives you access to power anytime for use during outages or peak pricing.

Boost Home Value

Homes with solar often sell faster and for more in competitive markets like Los Altos.

Enjoy Decades of Clean Energy

Once installed, solar panels need very little maintenance and produce clean power for decades.

Stay Powered During Outages

Keep your lights on and energy costs low with a backup battery. As utility companies ramp up planned shutoffs and unexpected outages continue during extreme weather and wildfire seasons, having your own power source is more important than ever.

We install top-rated batteries like Tesla Powerwall and Franklin Home Power to help you:

  • Stay powered during outages
  • Use solar energy even at night or when it’s cloudy
  • Avoid paying high utility rates during peak usage times
  • Gain more independence from the grid

Top Solar Battery Options

When it comes to solar batteries, you have options. Our top recommendations are the Tesla Powerwall 3, the FranklinWH Battery or the Enphase IQ. These batteries stand out for their performance and reliability. These batteries are all great options and deciding which one to pair with your solar system depends on your energy needs. 

When comparing these batteries, it’s important to understand two key specifications:

Energy Availability: This refers to the amount of power the battery can consistently provide, measured in kilowatts (kW). A battery with enough energy availability will be able to keep most homes (and all of their appliances) running as usual, even during an outage. 

Energy Storage: This is the total amount of energy the battery can store, measured in kilowatt-hours (kWh). A battery with a larger capacity allows homes to stay powered for longer than a battery with a smaller capacity. 

All of these battery options are designed to provide sufficient continuous power and energy storage to keep most homes running efficiently even when the grid goes out or during periods of reduced solar production.

Opting for a high-quality battery like one of these will help you decrease your dependence on the grid, save money and make sure you have reliable backup power ready when you need it.

Los Altos Utility Costs

In Los Altos, the average electric bill is around $240 a month. That’s well above the national average. With utility rates climbing every year, switching to solar can help you protect your wallet and plan for the future.

Here’s how electric bills in Los Altos compare to the rest of the country:

Built With Your Roof In Mind

We didn’t start as a solar company; we actually began as a roofing company in 1991. That means every solar system we install is designed with your roof in mind. Whether you need a roof inspection, repair, or a complete replacement, our in-house crews handle everything. No hassle. No delays. Just solid, reliable work.
