Solar Company Ranking Methodology

The Cost and Benefits of Solar in Donaldsonville
For many people considering switching to solar, the decision of which solar company to go with depends on prices. There are several factors you should consider when trying to figure out costs and your potential savings, such as:
- Electricity consumption: The average home in Donaldsonville uses a lot of energy, and so may see more savings on electricity bills than other places.
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 30% of the cost of installing your solar panel system from your federal taxes. Plus, not including incentives, you can save about $16,000 over 20 years on your energy bills.
- Average daily sunlight: Since Donaldsonville gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which influences how much your solar panels can save you on your electricity bills.
- The model of solar panels you want to get: More efficient panels have higher prices, so that will shape your budget for your solar project.
Although a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on a number of factors, such as the size of your house and incentives.

Solar Incentives in Donaldsonville
To increase solar panel installation and usage, incentives are offered by the government — and even some utility companies — to help make going solar more economically viable and accessible. When you install a solar panel system, you can claim the federal tax credit, or ITC. This credit currently lets you lower your tax bill by 30% of the cost of your solar panels. In addition, there are often some local incentives that you can take advantage of to further save. You can find out about the incentives you can take advantage of in our article on solar incentives
Environmental Impact of Switching to Solar in Donaldsonville
One of the reasons so many homeowners are thinking of going solar is to help bring down their environmental impact. You may be curious — how much do solar panels help the environment anyway? Going solar is a sustainable choice for the environment, due to the fact that the biggest source of greenhouse gas emissions in the U.S. is from burning fossil fuels for electricity, heat, and transportation — all of which can be powered by solar instead. After you go solar, your carbon emissions can be lowered by about 80 pounds every year. As you can see, trading traditional energy for solar has so many other benefits beyond saving money. One of the most important ones is that you can help save the environment too.
