The Cost and Benefits of Solar in Nashua
Solar panels are powered by a free energy source — the sun — but before you can take advantage of this you will need to pay to install your system. There are quite a few factors you should take into consideration when trying to determine costs and your potential savings, including:
- Energy consumption: Solar may be too pricey an investment for homes that don't consume a lot of energy each month.
- System size and type: Some models are more expensive than others, so the one you decide on can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
- How much you spend on energy: The typical household in Nashua pays around $1,000 a year on energy alone, so you could gain that much in savings.
- Incentives: Those who install a solar system this year can save 30% of their total solar spend by using the federal solar investment tax credit. You can also save about $19,000 on your energy bills over 20 years excluding incentives.
Because of the cost of solar panels being lower than before as well as various solar incentives, they are a cost-effective investment for the majority of homeowners.

On top of the federal tax credit incentive, there are also some state- and city-level benefits, which in the majority of cases, stack with the federal incentive, so you get to save even more. Take a look at our article on solar incentives to find out what incentives you can take advantage of.
Environmental Impact of Switching to Solar in Nashua
If you're considering adding solar panels to your home, one of the major reasons why may be to reduce your greenhouse gas emissions. But how much can switching to solar actually help the environment?
