The Cost and Benefits of Solar in Gretna

We know that for most homeowners, the choice to invest in solar rests 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 such as:

  • System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need, the more it'll cost.
  • Electricity consumption: The average household in Gretna uses a lot of energy, and consequently may see more savings on electricity bills than other places.
  • The amount of sunlight your city gets: Because of Gretna's very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • 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 result in an average of $17,000 of savings over 20 years.

Solar is a profitable investment for most homeowners. You can produce your own power instead of paying for it from a utility company and take advantage of solar incentives, all while helping the environment.

Solar Incentives in Gretna

There are many reasons why you should switch to solar. One of them consists of some government incentives that can save you money. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which lets you claim 30% of your project costs on your tax return, reducing the amount of taxes you owe that year. Plus, there may be some local incentives you can benefit from too. For detailed information about incentives that apply to you, see our our article on solar incentives.

Environmental Impact of Switching to Solar in Gretna

Switching to solar energy can have a beneficial impact on the environment. Something many homeowners might be thinking about is how much can they really help save the environment by switching to solar power anyway? For homeowners and business owners who want to help cut back on greenhouse gas emissions, using solar power is an easy decision, especially since Gretna produces a high amount of carbon dioxide emissions from its energy generation. Though solar panel production emits carbon dioxide, the panels make up for it by significantly lowering the amount of CO2 you would have released if you still used traditional energy. In Gretna, you can reduce your carbon footprint by 80 pounds a year with solar panels. If you care about the environment, you'll no doubt recognize that there are many benefits of adopting solar power other than just saving money on bills. You can also help preserve the environment, which some would argue is invaluable.

EcoWatch's Gretna, LA Solar Company Rankings FAQs

What is the most reputable solar panel installation company in Gretna?

In Gretna, PosiGen Green Grants is the best local solar company. Our team of experts rates it 5.00 stars, so it's a solid choice if you're looking to install solar panels on your house.

What is the negative environmental impact of solar panels?

Solar panels can be bad for the environment when manufacturers use toxic chemicals when they're made. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Making solar panels requires a lot of energy as well. The energy payback period is about 1 to 4 years.

Is it worth installing solar panels on my roof?

Solar panels can be a beneficial investment for many homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your electricity bills are already fairly low, solar panels might not be for you.

What is the efficiency of solar panels?

For the most part, solar panels are about 15 to 25% efficient, meaning they can convert that percentage of the energy from the sun into usable electricity.
