The Cost and Benefits of Solar in Mandeville

Solar panels run off a free energy source — the sun — but before you can take advantage of this you must first pay to set up your system. Some key things that affect the upfront cost and potential savings over time include:

  • Electricity consumption: The average home in Mandeville uses a lot of energy, and so may see more savings on electricity bills than other places.
  • The amount of sunlight your house gets: Because of Mandeville's very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • Incentives: Tax-paying citizens who install a solar system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $18,000 on your electricity bills over 20 years not including incentives.
  • The make and model of solar panels you're thinking of getting: More high-tech panels are more highly priced, so that will influence your budget for your solar project.

Though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on several factors, such as the angle of your roof and incentives.

Solar Incentives in Mandeville

Since solar power is better for the environment than fossil fuels, there are various government incentives available to encourage its adoption. You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar system. You can also potentially stack the ITC with other local incentives. Our article on solar incentives has more in-depth information on the incentives you can find in Mandeville.

Environmental Impact of Switching to Solar in Mandeville

One of the most compelling reasons to tap into solar power is to decrease your reliance on traditional energy sources like burning fossil fuels, which are destructive for the environment. A question many homeowners might be wondering about is how much can they really help the environment by switching to solar power anyway? In a city like Mandeville where energy use is particularly high, switching to solar energy is a fantastic plan for homeowners who want to do their part for the environment. Once you go solar, your carbon emissions can be lowered by about 100 pounds every year. If you care about the environment, you'll most likely find that there are many benefits of adopting solar energy other than just saving money on electricity. You can also help preserve the environment, which some would argue is priceless.

EcoWatch's Mandeville, LA Solar Company Rankings FAQs

Which solar power company is the best in Mandeville?

The best local solar company in Mandeville is PosiGen Green Grants, with a rating of 5.00 stars.

What are a few of the biggest pros and cons of switching to solar?

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

Is it worth putting solar panels on my roof?

Solar panels can be a good investment for most homeowners, but honestly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your power bills are already pretty low, solar panels might not be for you.

How often do solar panels need to be replaced?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is their energy production will have decreased by about 0.8% each year since installing them. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.
