The Cost and Benefits of Solar in Williamson

We understand that for most homeowners, the decision to invest in solar depends on installation costs. Some key factors that dictate the cost of installing solar panels on your home and how much money you could save over time are:

  • The cost of energy for you: If your local power rates are quite high, there's a good chance you'll see a higher return on your investment in a solar panel system. In Williamson, you can save an average of $109 a month on your electricity bills.
  • Where your home is: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 30% of the cost of your solar system installation from your taxes. Additionally, not including incentives, you can save about $24,000 over 20 years on your energy bills.
  • Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don't need to maximize efficiency, you can go with a higher number of more affordable panels.

Solar is a profitable investment for most homeowners. You can make your own electricity instead of paying for it from the grid and take advantage of solar tax credits and rebates, all while helping preserve the Earth.

Solar Incentives in Williamson

In order to increase the number of homes and businesses that use solar power, federal, state and local governments — and even some utility companies — offer incentives to help make going solar more economical and accessible. Everyone can take advantage of the federal Solar Investment Tax Credit (ITC), which allows you to claim 30% of how much your solar project cost when you file taxes, reducing the amount of taxes you owe that year. Additionally, there may be some local incentives that stack with the ITC too. Our article on solar incentives goes over more in-depth information on the incentives you can find in Williamson.

Environmental Impact of Switching to Solar in Williamson

There are a few big reasons why homeowners are considering solar energy: to put more money in their bank account and to help the planet. You may be asking yourself — how much does making the switch help the planet anyway? No matter where you are, you can help protect the environment by switching to solar energy, but homes that use a lot of energy will have an even bigger impact. Once you go solar, your carbon footprint can be reduced by about 100 pounds every year. As you can see, trading traditional energy for solar has so many other benefits outside of saving money. One of the primary ones is that you can help save the Earth too.

EcoWatch's Williamson, AZ Solar Company Rankings FAQs

Which solar installation company is the best in Williamson?

The top local solar company in Williamson is PE SOLAR, with a rating of 5.00 stars.

Are solar panels really eco-friendly?

Making solar panels requires chemicals and produces toxic waste that can be dangerous for the environment, which is the main drawback of solar panels.

Are solar panels worth it?

Solar panels can be a good investment for a majority of homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already reasonably low, solar panels might not be for you.

When is the best time of year to install solar panels?

Despite summer being the most popular time people install solar panels, the optimal time is actually winter. You can save money since there's less demand during the winter months, and it allows you to be up and running with solar for the more expensive power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
