Benefits of Solar Energy

Solar energy provides multiple perks. Here are some highlights.

  • Reduced carbon footprint: Solar is a highly abundant clean energy source, meaning you can lower or beat your home's dependence on "traditional" sources.
  • Better energy independence: Solar energy can keep your home functioning through emergencies and blackouts, giving you additional security. You can use your solar energy anytime with optional battery backup.
  • Lower utility costs: Producing some or all of your own power will spend less on electricity long-term. Plus, some states offer net metering programs that make it possible for you to sell your unused energy back to the grid, generating additional credits toward your energy bill.

How To Choose the Best Solar Company in Cambridge

The purchase price and efficacy of solar panels often depend on the provider that mounted them. Here are some essential aspects to remember while searching for a solar specialist.

Licensing and Training

Massachusetts requires new solar PV systems in the Commonwealth to be installed by a licensed electrician and new solar water heaters to be installed by a construction supervisor. Check for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar industry's most respected trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Cambridge

The kind of solar panels you select determines how much electricity 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 the best for large residential installations, but they are excellent accessories for non-traditional roofs.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can enhance your solar system's performance. Not all solar companies offer these extras, so look for a company that sells them if it's essential for you.

If you're a resident of Cambridge and are considering getting a five-kilowatt solar energy system, you could plan to spend about $20,300 for materials and labor. See more information on specific component and solar panel costs in the table.

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 Cambridge

Choosing the best financing plan will affect your overall solar system cost and expected savings. Common payment options include leases, loans, cash payments, and power purchase agreements. We advise paying with cash or using a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also own your system and can apply for solar panel incentives to minimize your total costs. Solar loans are another solid option if you don’t want to make a big initial investment. You can pay for your system in monthly installments while still benefiting from energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases allow you to rent your panels for a fixed monthly rate, while PPAs let you pay just for the energy you use, much like an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. We suggest working with a contractor that offers multiple financing options. Talk to each salesperson about what's available, and obtain more than one estimate for the best odds of staying within your budget.

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

The IRS allows you to claim a 26% federal tax credit for solar panels on total system costs, so long as you purchase it before 2032. Municipal authorities and utilities might also offer their own financing programs, rebates, and incentives that could save you more money.

1 kW2.0 years

10 kW19.6 years
