The Cost and Benefits of Solar in Nashua
We get that for lots of homeowners, the decision to invest in solar highly depends on installation costs. Some key factors that affect the cost of installing a solar panel system on your home and how much money you could save over time include:
- Choice of solar panels: The kind of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don't need to maximize efficiency, you can go with a higher number of more affordable panels.
- The amount of sunlight your area gets: Thanks to Nashua's relatively low amount of average daily sunlight, you might not see as many savings on your power bills.
- Incentives: Those who buy and install a solar system this year can save 26% of their solar installation costs by using the federal solar investment tax credit. You can also save about $19,000 on your electricity bills over 20 years not including incentives.
- How much power your household consumes: Households that consume lots of power each month may need more solar panels and, therefore, be more expensive, but will also enjoy more savings over time.
Solar is a profitable investment for most homeowners. You can produce your own power instead of paying for it from the grid and make use of solar incentives, all while helping protect the planet.

Environmental Impact of Switching to Solar in Nashua
If you're considering adding solar panels to your home, one of the principal reasons why may be to reduce your greenhouse gas emissions. But how much can using solar energy instead of traditional energy actually affect the environment? One thing that can drastically affect your carbon footprint is your commute time and how much you drive generally. If you go solar and have an electric car, you can greatly cut back on your carbon dioxide emissions by charging your car at home. While solar panel manufacturing releases carbon dioxide emissions, the panels make up for it by considerably reducing the amount of CO2 you would have produced if you still used traditional energy. In Nashua, you can reduce your carbon footprint by 40 pounds a year with solar panels. The advantages of solar power are plentiful — just like solar power is! That's why so many people have been happy with committing to solar.
