The Cost and Benefits of Solar in Washington

The cost of putting up a solar panel system has decreased significantly over the past several years, but it's still a significant investment for most homeowners. A few key factors that determine the cost of installing a solar panel system on your home and how much money you could save over time include:

  • Incentives: Tax-paying citizens who install a solar energy system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $12,000 on your electricity bills over 20 years without incentives.
  • Average daily sunlight: Since Washington gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which affects how much your electricity bills will be.
  • Your income and budget: This shapes what kind of solar panels you can afford.
  • Your current electric bills: Solar panels can dramatically decrease, or completely eliminate, your utility bills. In Washington, you can save an average of $91 a month.

There are lots of wonderful benefits of solar in spite of the initial cost of installation. It can help the Earth and your wallet. In addition, it can boost the value of your home, giving you even more benefits if you decide to sell your home later.

Environmental Impact of Switching to Solar in Washington

A lot of people want to do what they can for the planet, which often is the prime reason for installing solar panels. But — how much exactly can you help the planet by using solar power? One thing that can severely shape your carbon footprint is your commute time and how much you drive generally. If you go solar and have an electric car, you can greatly cut back on your carbon dioxide emissions by charging your car at home. In fact, if you install solar panels, you could lower your carbon dioxide emissions by about 60 pounds each year. If you care about the environment, you'll most likely get that there are many good things about adopting solar power other than just saving money on electricity. You can also help preserve the environment, which some would argue is invaluable.
