Solar Incentives in Keene
One of the benefits of installing a solar panel system is earning federal and potentially state incentives. Regardless of where you live, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will let you claim 30% of how much your solar project cost when you file taxes, lowering the amount of taxes you owe that year. Additionally, there may be some local incentives you can benefit from too. In our article on solar incentives, you can see the incentives you qualify for in Keene.
Environmental Impact of Switching to Solar in Keene
There are a few big reasons why many people want to invest in solar energy: to put more money in their bank account and to help the planet. But how much can using solar energy instead of traditional energy actually help the environment? As stated 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. Using solar power can help bring down that number in a city like Keene that produces a fair amount of carbon dioxide emissions each year. Since solar panels don't release carbon dioxide emissions into the atmosphere when generating electricity, they're a good alternative to traditional energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 40 pounds each year. For homeowners who are concerned about the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.
