You've got solar questions, we've got answers

We've gathered the top questions from home owners and answered them below. Have a question that we haven't covered? Please contact us.

How much do solar panels cost 2017?

Because each solar panel system is custom designed for a home or business, there is no “one cost” of solar panels. Each installation begins with a customized quote based on several factors, including how much you spend on electricity, how large your roof is, and if you’re a residential or commercial customer. For residential installations (and commercial, if chosen), Boston Solar gives customers the choice between LG, Hyundai and SunPower solar panels. Click here to learn more about the products we offer.

How much will I save with solar panels?

Boston Solar customers can save up to 100% of their utility bill (excluding the utilities standard service charge), depending on monthly energy usage and amount spent.

Is solar financing available?

For residential customers, Boston Solar offers a variety of solar finacing options. Not interested in owning your own system? No worries - we also offer a solar lease through SunPower. A Solar Consultant will explain our options and customize a solution that has you cash flow positive in the first year. To learn more about residential financing options, click here.

How long will it take to install my system?

For residential customers, the solar panel installation is typically a one or two day process. From the moment you sign a contract, it typically takes between 90 to 120 days to install the system and get it turned on. 

Will I still need to use the electric utility?

You will always receive something from your energy company.  Even if solar covers 100% of your electricity needs, the electric utility still charges a minimum "customer charge" because they are still providing you with a meter and energy, should you need it. Solar energy needs to be consumed in real time, unless you are using a storage solution, currently not offered by Boston Solar. You will use the power from your system as the energy is generated. The energy not used is credited on your utility bill. When the sun is not shining or powering your home or business, you will use electricity from the grid. The amount of energy that your system generates will offset or, in some cases, eliminate the electricity part of your utility bill.

How much will it cost me and my family to solar power my home?

Every solar panel system is custom designed. Between financing and incentives, customers are usually cash-flow positive in their first year. Massachusetts has one of the strongest solar incentive programs in the country. In addition, federal tax credits and low-interest solar loans contribute to a positive cash flow.

Is solar energy more expensive than utility rates?

Electricity prices typically fluctuate seasonally and have increased on average by 4% nationally over the last 10 years. By owning a solar system, you produce your own power and are less exposed to the volitility and future electricity cost increases.

What is the latest news in Massachusetts solar energy incentives?

On January 31, 2017, the Massachusetts Department of Energy Resources (MA DOER) announced an extension to the lucrative Solar Renewable Energy Credit (SREC) program for home owners and businesses who purchase or finance a solar system.  SRECs provide a quarterly payment to home owners for every 1,250 kWh of electricity produced. However, SRECs will end in 2017 which is why NOW is the time to go solar. You also qualify for a 30% federal tax credit and will receive up to $1,000 state tax credit. If a customer chooses a solar lease or Power Purchase Agreement (commercial customers only) instead of purchasing or financing, they are not eligible for any federal or Massachusetts solar incentives.

What kind of maintenance do solar panels require?

Our solar systems are warrantied to last 25 years and are virtually maintenance free, with the exception of the inverters, which typically last 12-15 years.  However, our residential systems come with an automatic inverter warranty extention from 12 to 25 years. We are the only residential installer to do so. Click here to learn more about the products for residential solar systems.

Is there a warranty on my solar system?

Boston Solar offers the strongest warranty package in Massachusetts at no additional cost to the customer. Solar panel warranties are 25 years, we extend the warranty for inverter(s) to 25-years and also include a 10-year workmanship guarantee. In addition, for residential customers, we also include a 25-year production guarantee, which no other Massachusetts solar panel installer offers.

See how much you could save by going solar with Boston Solar. Boston Solar offers many financing and payment options to help you go solar with $0 down. 

Purchase Your Solar System

Over the next 10 years, SRECs are paid out quarterly for the energy you produce.

Finance Your Solar System

To get around the hurdle of upfront costs, we offer 100% financing programs through Massachusetts Solar Loans and Sungage Financial.  This allows you to own your solar array, take advantage of all the tax credits and rebates, and make a profit in the first year.  A solar system saves you on your electric bills and earns you quarterly income through Solar Renewable Energy Credits (SRECs).  You pay nothing out of pocket and still have greater system generated savings than your low monthly payments.

Lease Your Solar System

If you choose a solar lease facilitated by Boston Solar, the solar lease provider owns the solar panel system, receives all of the federal tax credits, state rebates and quarterly SRECs and you have a monthly lease payment for 20 years. You will still receive benefits of a lower utility bill, but will not own the system.
