Benefits of Solar Energy

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

  • Better energy independence: Photovoltaic systems with battery backups function through power outages and emergencies, and you won't have to depend on the electrical grid for your safety and well-being.
  • Smaller power bills: Sourcing some or all of your own electricity will save you money on your electric bills long-term.
  • Reduced carbon footprint: Using clean solar power lowers your dependence on conventional, less environmentally-friendly sources.

How To Choose the Best Solar Company in Shrewsbury

The more thorough your company investigation is, the better your solar system will ultimately function. Consider each of these criteria in your service provider search.

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 companies can also earn certifications from trade groups and standards organizations. The most recognized ones in the industry come from the NABCEP. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Shrewsbury

The type of solar panels you select dictates how much power you can generate. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. 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 battery backups and electric vehicle (EV) chargers. These will increase your total project price, but they can increase your solar system's efficiency. Not all solar companies include these additional features, so look for a contractor that installs them if it's important for you.

Most Shrewsbury homeowners select solar systems sized for five kilowatts (kW) of electrical capacity. These systems run about $20,300 to set up, considering both materials and labor. You can find more specific cost information in the table.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,230
Solar Polycrystalline $959
Thin-Film $561
Solar Battery $787
Solar Home EV Charger $2,951

Financing Solar Energy in Shrewsbury

Solar companies use multiple different financing options to increase your savings and lower your costs. Though some providers offer unique payment plans, the most common are cash payments, solar loans, power purchase agreements (PPAs) and solar leases. Most solar experts recommend a cash payment or using a solar loan. Cash payments demand a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Much like a car or home loan, you'll pay a set monthly rate with potentially $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) lets you pay a monthly rate determined by the energy you use, as with an electric bill. We generally don’t recommend these two options because you won't own the solar system and are disqualified from using solar incentives. We advise working with a provider that offers multiple financing options. Speak with each salesperson about what's available, and acquire more than one estimate for the best odds of keeping within your financial plan.

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

A 26% federal tax credit applies to recently-purchased solar equipment purchased through 2032. Additional incentives may be available through local governments, usually in the form of rebates and special financing programs.

Solar System Capacity Estimated Payback period
1 kW 2.0 years
2 kW 3.9 years
5 kW 9.8 years
10 kW 19.6 years

Frequently Asked Questions About Solar in Shrewsbury

How much energy and money could I save per year by switching to solar?

On average, Shrewsbury homeowners pay around $1,296 per year on power bills. Once you pay off your solar array, you could reduce your costs by $1,045.78 for every kilowatt you produce.

How prevalent is solar energy in Shrewsbury?

Yes, solar energy is gaining popularity in Shrewsbury. Some homes already generate solar power on-site or through utility grids, and they're supported by a state solar economy with 10400 jobs and counting.

Should I anticipate a property value increase after installing solar panels?

Yes, a solar PV system will boost your property value. According to the National Renewable Energy Laboratory, for every dollar you reduce on energy bills, your home value rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How long does the solar panel installation process require?

There's no universal answer for how long a solar project might take. Ultimately, it depends on local weather, the permitting and inspection process, the necessary prework, system size, and panel style. Many homeowners can be solar-ready within a few months from their initial estimate visit.

What upkeep do my solar panels need, and how often do they need it?

Solar panels don't require much upkeep to keep working well. All you'll need to do is clean and inspect the panels every six months or as necessary in dusty seasons. Solar installers frequently offer maintenance packages to assist in your system's care.

What's the average solar system size in Shrewsbury?

A typical Shrewsbury solar home has a 4.5-kW panel array, but you might need a bigger system if your energy needs are more demanding. Solar contractors will consider your property's power usage and roof shading to recommend the right system for you.

What are some "red flags" to watch for as I research companies?

Even the most renowned Shrewsbury solar installers will have both glowing and critical reviews. To make the most informed decision possible, focus on these warning signs to know if a company isn't worth your time:
  • High-pressure sales tactics
  • Dodging questions about cost, training and credentials, warranties and references
  • Inflexible options
  • Rushing through the site assessment
  • No references or testimonials
