We assessed dozens of Waltham solar providers, using the following criteria to select the best:

  • Panel quality and brand offerings: The leading solar companies stay up-to-date with new technology, offering equipment from innovative, dependable manufacturers.
  • Feedback and reviews from customers: Most Waltham solar contractors have both favorable and unfavorable reviews. However, a good review ratio reflects a company's trustworthiness and responsiveness to issues.
  • Educational programs and business model: Solar technicians must be good teachers. They should use their years of experience address your questions on how to look after your system and maximize its performance.
  • Certifications and credentials: Each installer on our list meets state and city licensing requirements and stays up to date with industry best practices. Many of them have served the Waltham community for over 15 years.

Benefits of Solar Energy

Solar energy offers multiple advantages that will enhance your home for years to come.

  • Lowered energy bills: With a solar array, you create power without paying the tacked-on costs of grid-connected power. You can eliminate your bills completely if you go off-grid. Plus, a significant number of states offer net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Reduced carbon footprint: Embracing solar is a surefire way to decrease your carbon footprint and home fossil fuel dependency.
  • Better energy independence: Photovoltaic solar panel systems with energy storage systems function through power outages and emergencies, and you won't have to rely on the power grid for your safety and well-being.

How To Choose the Best Solar Company in Waltham

The purchase price and efficiency of solar panels often depend on the solar company that mounted them. Here are some important factors to consider while shopping for a solar provider.

Licensing and Training

Massachusetts requires new solar photovoltaic systems in the Commonwealth to be installed by a licensed electrician and new solar water heaters to be installed by a construction supervisor. Solar providers can also pursue certificates from trade groups and standards organizations. The most prestigious ones in the industry come from the North American Board of Certified Energy Practitioners. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Waltham

The type of solar panels you purchase decides how much power you can generate. Monocrystalline panels and high-quality and cost more but give you the best performance. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

You can also add electric vehicle (EV) chargers and battery backup systems. These will increase your total installation cost, but they can enhance your solar system's performance. Not all solar contractors provide these additional features, so look for a company that installs them if it's crucial for you.

Generally speaking, it will cost about $20,300 for a five-kilowatt solar array in Waltham. This table displays more specific prices for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,241
Solar Polycrystalline$968
Thin-Film$566
Solar Battery$794
Solar Home EV Charger$2,978

Financing Solar Energy in Waltham

There are a plethora of ways to pay for a solar energy system, and the right one will reduce your expenses. A few of the most common options include power purchase agreements (PPAs), leases, cash payments, and loans. Though it requires a large up-front payment, cash is the most cost-effective choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the next best option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases allow you to pay a monthly rate to rent your panels, while a PPA lets you pay a fluctuating rate based on only the energy you use. We generally don't recommend these options since you won't own your system and are disqualified from solar incentives, but they might be appropriate in specific circumstances. We recommend working with a provider that offers multiple financing options. Speak with each salesperson about what's available, and obtain more than one estimate for the best odds of keeping within your spending limits.

The table below lists the average payback periods for different capacities of solar systems in Waltham.

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, local governments and utilities may have their own financing plans and rebates that could reduce your total cost even more.

1 kW2.0 years

10 kW19.6 years
