The Cost and Benefits of Solar in Waltham

We understand that for most homeowners, the decision to invest in solar hinges on installation costs. There are several factors you should take into consideration when trying to determine the overall cost and how much you can save, including:

  • Electricity consumption: The average home in Waltham doesn't use much energy, and so may not see as many savings on their power bills.
  • The type of solar panels you're planning on getting: Some have higher prices, so that will shape your budget for your solar project.
  • Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 30% of the project cost. Your state and even local utility companies may also have incentives and rebates that you can take advantage of. In addition, you can save about $23,000 over 20 years on your utility bills, not including incentives.
  • Your household's power bills: Due to fairly high monthly power bills in Waltham, you could save about $1,100 a year with solar.

There are lots of good benefits of solar in spite of the initial cost of installation. It can help the Earth and your bank account. Plus, it can raise the value of your home, giving you even more benefits if you want to sell your home later.

What are the advantages and disadvantages of solar power?

The most notable cons are that solar panels don't produce electricity at night, the startup costs are high and solar panels can look clunky on your roof.

Are solar panels worth it?

Solar panels can be a good investment for a majority of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your power bills are already reasonably low, solar panels might not be for you.

What is solar panel capacity and how much do I need for my house?

Solar panel capacity is rated depending on how much power they generate under standard testing conditions. Since each panel can usually produce about 250 to 400 watts per hour, the average home will need 20 to 35 panels.
