The cost of putting up solar panels has gone down greatly over the past several years, but it's still a significant investment for most homeowners. There are a few factors you should take into consideration when determining how much it will cost and how much you can save, including:
- Your home's power bills: With fairly high monthly electric bills in Medfield, you could save about $1,000 a year with solar.

Environmental Impact of Switching to Solar in Medfield
Switching to solar energy can have a beneficial impact on the environment. You may be trying to figure out — how much do solar panels do for the planet anyway? Going solar is an impactful choice for the environment, because the biggest source of greenhouse gas emissions in the country is from burning fossil fuels for electricity, heat, and transportation — all of which can be powered by solar instead. Since solar panels don't release CO2 emissions into the atmosphere when generating electricity, they're a good substitute for traditional energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 40 pounds each year. If you want to do what you can for the environment, you'll most likely recognize that there are many benefits of adopting solar energy other than just saving money on bills. You can also help preserve the environment, which some would argue is invaluable.
