How To Choose a Solar Company

Going solar can be a great way to save money on electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when deciding if a solar installer is reliable.

Check Licensing

Make sure you hire a licensed solar installer. This helps ensure that the work is done correctly using the most up-to-date installation methods. 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.

Read Customer Reviews

Check review sites like the Better Business Bureau (BBB), Google Reviews, and TrustPilot to see feedback from past customers about local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar company that works with your budget, ask for free, detailed quotes from 3–5 providers. The quotes should outline all costs and list the solar equipment included. Looking at several quotes helps you identify the option that best fits your budget.

Ask About the Warranty

High-quality solar installations should have robust workmanship and performance warranties. The workmanship warranty covers any installation issues like poor wiring, poor alignment, or cracks in the panels. The output warranty guarantees an energy generation baseline. Strong guarantees reflect a solar provider's faith in its installations.

Evaluate Financing and Incentives

Installing solar panels can help lower your electric bills over time. When considering the total price and value of solar panels, make sure to consider these factors.

  • Look into utility rebates: Local power companies may have extra discounts to incentivize homeowners to adopt solar power. Review the qualification rules and rebate amounts with your local provider to calculate your potential savings.
  • Research federal and state tax credits: A 26% federal tax credit for the full solar system cost is available through 2032. Many states provide incentives, too. The credits can lead to substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased upfront or paid for over time through a lease or loan. Review all terms when financing, such as annual percentage rate (APR), fees, payment schedule, and ownership implications.

Cost of Solar Installation in Waltham

The cost of home solar panels in Waltham depends on several factors, including the area and generating capacity of your panel array and the type of panels you'll use. Generally speaking, a typical solar energy system costs $4,060 per kilowatt, not including labor, permit fees, or preliminary work. Most solar systems in Waltham are 4.5 kilowatts, and the typical Waltham homeowners spends $12,674 after accounting for federal tax refunds. Some homeowners may prefer leasing their solar panels to reduce upfront costs.

Frequently Asked Questions About Solar in Waltham, MA

A solar photovoltaic (PV) array can generate power to run any electric appliance or system in your home. A more specific example is installing a solar water heating system.

There are many advantages of home solar energy. You can reduce emissions, save money, and raise your property values. With the right storage equipment, solar panels can also provide you with further energy independence and offer some protection from power outages.

It depends on where you live and the kind of panels you plan to use. Waltham can experience long, hard winters, so we recommend installing your system in the springtime to maximize your generation for the year.

Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Waltham, the average amount someone can save is $1,069 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system once the payback period passes.

Your payback period is the time to earn a net profit from your solar panels. It will vary based on the average sunlight in your area, the rate your utility charges per kilowatt of power, and their rated capacity. Waltham gets quite a bit of sunlight per day, so an average payback period could last up to 11.9 years per 5 kW of capacity.

Yes. Solar panels exist independently from the power grid in Waltham and will continue to generate power even if the grid is having problems. Keep in mind, however, that a solar system without a storage system cannot keep you running through a nighttime outage. Your contractor can discuss some economical options to keep your home's power access reliable through the worst conditions, including battery backups or an emergency generator.

Solar energy is on par with other forms of renewable energy. Their maintenance costs are low and today's systems can work in a variety of conditions.
