The Cost and Benefits of Solar in St Louis

We get that for most homeowners, the decision to invest in solar depends on installation costs. The installation cost is just one important factor you should bear in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:

  • How much power your home consumes: Households that use a lot of power each month may call for more solar panels and, consequently, be more expensive, but will also enjoy more savings over time.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 26% of your total installation cost, your 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 $17,000 over the first 20 years with your solar system, too.
  • Average daily sunlight: Since St Louis gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which influences how much you can save on your energy bills.
  • The type and model of solar panels you're thinking of getting: More efficient models cost more, so that will influence your budget for your solar project.

Solar is a fruitful investment for most homeowners. You can make your own power instead of paying for it from a utility company and benefit from solar incentives, all while helping preserve the planet.

Environmental Impact of Switching to Solar in St Louis

If you're thinking of adding solar panels to your home, one of the principal reasons why may be to lower your carbon dioxide emissions. But how much can switching to solar actually affect the environment? Using solar energy for electricity instead of relying on nonrenewable energy sources is an impactful way to reduce carbon dioxide emissions if you're conscious of St Louis's large level of greenhouse gas emissions. If you go solar, your carbon emissions can be lowered by about 100 pounds a year. As you can see, going solar has so many other rewards apart from saving money. One of the main ones is that you can help save the Earth too.

EcoWatch's St Louis, MO Solar Company Rankings FAQs

What is the top solar panel company in St Louis?

The best local solar company in St Louis is EFS Energy Inc, with a rating of 4.52 stars.

What are a few of the advantages and disadvantages of switching to solar?

A few of the biggest pros are that it lets you spend less on your power bills, it's eco-friendly, and it gives you a good return on your investment (ROI). The most notable cons are that solar panels don't work as well when there's limited direct sunlight, there is a high upfront cost and solar panels can be an eyesore.

How long does it take for solar to pay for itself?

Solar panels typically pay for themselves in about 11.0 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will recoup your installation costs.

How often do solar panels need to be replaced?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
