The Cost and Benefits of Solar in Gretna

Solar panels are powered by a free energy source — the sun — but to take advantage of this you will first need to pay to set up your system. A few key factors that influence the cost of installing a solar panel system on your home and how much it could save you over time are:

  • How much energy your household consumes: Households that need a lot of power each month may need more solar panels and, as a result, be more costly, but will also save more on their energy bills over time.
  • The amount of sunlight your house gets: Due to Gretna's very high amount of average daily sunlight, you should be able to save a lot on your electricity bills.
  • Incentives: Tax-paying citizens who purchase and install a solar system this year can save 30% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $17,000 on your utility bills over 20 years without incentives.
  • The type of solar panel system you have the money for: This hinges on what your budget is.

There are several great benefits of solar despite the initial cost of installation. It can help the planet and your bank account. Plus, it can increase the value of your home, resulting in even more benefits if you want to sell your home later.

There are a few important reasons why homeowners are interested in solar energy: for the financial and environmental benefits. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Gretna, though. As reported by the EPA, electricity generation is the second largest source of greenhouse gas emissions and about 62% of our electricity is produced by burning fossil fuels. Switching to a clean energy source like solar power can help bring down that statistic in a city like Gretna that is responsible for a sizable amount of carbon dioxide emissions each year. Once you go solar, your carbon emissions can be reduced by about 80 pounds every year. For people who care about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

EcoWatch's Gretna, LA Solar Company Rankings FAQs

What is the top solar company in Gretna?

The best local solar company in Gretna is South Coast Solar, with a rating of 4.98 stars.

What are the advantages and disadvantages of solar power?

The biggest advantages of solar power are that it can decrease or, in some cases, entirely cut your electricity bills, raise your home's value and reduce your carbon footprint. The biggest disadvantages are that solar panels can be pricey 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.

Are solar panels worth it?

Solar panels can be a great investment for many homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already pretty low, solar panels might not be for you.

What is the best type of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof configuration and how much energy generation you want.
