The Cost and Benefits of Solar in Portland

The cost of putting up a solar panel system has gone down greatly in the past several years, but it's still a large investment for most homeowners. The cost of solar and the savings it generates vary depending on some important factors such as:

  • The type of solar panels you can afford: This depends on your income and budget.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 26% of the cost of your solar system installation from your federal taxes. In addition, not including incentives, you can save about $16,000 over 20 years on your energy bills.
  • Your home's power bills: With high monthly electric bills in Portland, you could save about $900 a year with solar.
  • How much power your household needs: If your home uses a lot of energy, you'll see more savings from going solar.

There are lots of great benefits of solar in spite of the initial cost of installation. It can help the planet and your finances. In addition, it can increase the value of your home, resulting in even more benefits if you decide to sell your home later.

Environmental Impact of Switching to Solar in Portland

There are a few big reasons why many people are considering solar energy: to help their wallet and the environment. Something many might be thinking about is how much can they really help save the environment by switching to solar power anyway? One thing you should keep in mind is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions. If you go solar, your carbon emissions can be lowered by about 40 pounds every year. Since solar energy is renewable and makes electricity without releasing carbon emissions, making the switch to solar power is one easy step you can take to help protect the environment.
