  • Choice of solar panels: The kind of solar panels you are interested in getting will affect your total cost.

Your state and even local utility companies may also have incentives and rebates that you can use. Additionally, you can save about $22,000 over 20 years on your utility bills, without incentives.

Environmental Impact of Switching to Solar in Millis

One of the most compelling reasons to embrace solar power is to decrease your dependence on nonrenewable energy sources like burning fossil fuels, which are harmful for the environment. You may be asking yourself — how much does going solar do for the planet anyway? According to the EPA, electricity production is the second greatest source of greenhouse gas emissions and about 62% of our electricity is produced by burning fossil fuels. Switching to a clean energy source like solar power can help bring down that statistic in a city like Millis that is responsible for a fair amount of carbon dioxide emissions each year. If you go solar, your carbon footprint can be reduced by about 40 pounds a year. Since energy from the sun is plentiful and produces electricity without free from carbon dioxide emissions, making the switch to solar power is one easy step you can take to help the planet.
