Solar Company Ranking Methodology

The Cost and Benefits of Solar in Portland

When picking a solar company, most homeowners or business owners worry about the costs above all. Some key factors that determine how much it will cost to install a solar panel system on your home and how much money you could save over time include:

  • Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your energy bills, which can generate an average of $23,000 of savings over 20 years.
  • The cost of energy for you: If your local utility rates are quite high, there's a good chance you'll end up with a higher return on your investment in a solar panel system. In Portland, you can save an average of $90 a month on your electricity bills.
  • How much power your home consumes: Households that need plenty of electricity each month may call for more solar panels and, as a result, be more expensive, but will also benefit more over time.
  • The type and model of solar panels you're thinking of getting: More efficient models have higher prices, so that will determine your budget for your solar project.

Solar is a fruitful investment for most homeowners. You can generate your own energy instead of paying for it from the grid and take advantage of solar tax credits and rebates, all while helping preserve the environment.

Environmental Impact of Switching to Solar in Portland

One reason so many are thinking of going solar is to help bring down their environmental impact. But — how much exactly can you help the planet by using solar power? One thing that can drastically influence your carbon footprint is how long your commute is and how much you drive in general. 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. Since solar panels don't release carbon dioxide emissions into the atmosphere when creating electricity, they're a good trade for traditional energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 40 pounds each year. The advantages of solar power are infinite — just like solar power is! That's why so many Portland residents have been happy with committing to solar.
