Solar Company Ranking Methodology

The Cost and Benefits of Solar in Waltham

We understand that for many homeowners, the choice to invest in solar highly depends on installation costs. Some key factors that dictate the cost of installing solar panels on your home and how much money you could save over time include:

  • Energy consumption: Installing solar panels may be an expensive investment for households that don't need too much energy a month.
  • The cost of energy for you: If your local utility rates are quite high, there's a good chance you'll end up with a higher return on your investment in a solar system. In Waltham, you can save an average of $89 a month on your electricity bills.
  • Incentives: The federal solar investment tax credit, which can save you some money, allows you to deduct 30% of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $23,000 over 20 years on your energy bills.
  • Choice of solar panels: The type of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.

Solar is a fruitful investment for most homeowners. You can make your own energy instead of paying for it from the grid and make use of solar tax credits and rebates, all while helping the environment.

In fact, if you install solar panels, you could look forward to lowering your carbon dioxide emissions by about 40 pounds each year.
