The Cost and Benefits of Solar in Washington

When deciding on a solar company, most homeowners or business owners worry about the costs above all. A few key factors that influence how much it will cost to install solar panels on your home and how much it could save you over time include:

  • average energy usage: The more electricity your home consumes on average and the greater your current electricity bills are, the more money you could save by switching to solar.
  • System size and type: Some models are more expensive than others, so the one you choose can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $12,000 over the first 20 years with your system, too.
  • How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panel system won't be able to produce as much energy, which will give you lower savings on power bills than someone with a roof that gets lots of sunlight.

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

Solar Incentives in Washington

Although installing solar panels is typically a big investment, it can save you a significant amount of money over many years because of smaller power bills and government incentives. Local solar incentives depend on the location and, sometimes, utility company. Many states offer rebates for home solar power systems, in addition to the federal solar tax credit. In our article on solar incentives, you can read about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Washington

There are many reasons to make the switch to solar power, like saving on utility bills and helping to lower your carbon footprint. But you may be wondering — how much exactly can you help the environment by using solar power? If your family consumes lots of energy, you can help the environment even more by switching to solar power. When you go solar, your carbon dioxide emissions can be lowered by about 60 pounds every year. For homeowners who are concerned about the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.

In Washington, GreenBrilliance is the top local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're planning on installing solar panels on your home.

What are a few of the major pros and cons of installing solar panels?

The biggest advantages of solar power are that it can lower or, in some cases, entirely eradicate your electricity bills, raise the value of your home and cut back on your carbon footprint. The biggest disadvantages are that solar panels can be costly to install, you may not see as many savings if you don't use a lot of electricity and it doesn't work for all roof types and locations.

How long does it take to see a return on your investment after buying solar panels?

Solar panels typically pay for themselves in about 17.0 years, but your solar payback period will vary depending on your utility costs. The more your typical electricity bill, the quicker your solar panel system will pay for itself.

What is solar panel capacity and how much do I need for my house?

Solar panel capacity is how much energy the panels can create under ideal conditions (a sunny day around noon). The average household has to install between 20 and 35 panels to cover their typical energy usage.
