General Questions:

How long will it take to break-even?

Residential homeowners will typically break-even in five to seven years. Variables include electrical production, applicability of investment tax credits (ITC), use of accelerated depreciation (commercial projects), and applicable State incentives. See our Financials videos for more information

I don't have much free cash; are there financing options?

Yes. No money down, competitive interest rate loans are available through Mass Solar Loan and/or UMassFive College Federal Credit Union. The following link to UMassFive’s solar loan program summarizes both: Solar Loans

What if my roof doesn't face South?

Although South facing is the optimal exposure, any exposure between East and West allows for a viable system. We complete a 'sun exposure' analysis to project the energy your system can generate. For those without a suitable rooftop, we offer ground-mounted systems, and our "Better Than South" Trackers.

I don't want them on the roof; can I put them on the ground?

YES, we love to do ground-mounted systems. With ground-mounts we can optimize the solar panel tilt for your exact location on the planet and position the system to minimize shading. And, because ground mounts run cooler, electrical production is higher. With a well-sited ground mount or tracker system you can expect to produce up to 30% more energy than the same size rooftop system.

What if I have trees that block the sun?

Using irradiance and sun tracking tools, we can project your solar production as compared to having no trees. If production suffers significantly, we would recommend trees to be trimmed and/or removed*.

2020 Web FAQs 2 What should be the maximum age of my roof to support a solar installation?

Each roof is different. For all roof mounted systems we complete an onsite assessment to determine suitability for installing solar. If repairs, re-surfacing, and/or a new roof are required, loans* can be structured to include those costs.

How long will solar incentives be in place?

Solar incentives may be classified as one-time, or on-going. The one-time tax credits are declining, but the on-going incentives - specifically here in Massachusetts - will pay solar owners for up to twenty years. Because all incentives are temporary and historically have declined, it's always better to commit to solar sooner rather than later.

What are the incentives?

Today's incentives include Federal and State tax credits and ongoing SMART payments from the utility. For an overview of current incentives and other financial aspects, see our video:'Solar Incentives', our Buying vs Leasing Fact Sheet, and see the 'Financial' tab on our website.

What happens if my system produces more electricity than I use?

The utility will credit all or part of any month’s excess production to your account to be applied to any bill when usage exceeds solar production.

Residential Questions:

I don't like the way some modules look; they have too much silver or look like a checkboard. Are there options?

Yes, today all black solar panels are popular and available.

How long will it take to install the system on my home?

We strive to have systems installed within 90 days of contract signing. Larger systems and any work with banks and financial institutions will require more time.

What if I sell my house in the next few years?

According to national realtor organizations, solar arrays add about 4% to the overall sale price of the home. Most important, because you own** the system, selling a house with solar is easy.

Will the assessed value of my home increase if I install solar?

No. Massachusetts law specifically prohibits increases in assessed value when solar is installed.

Why wouldn't I lease a system?

See our Buying vs Leasing Fact Sheet below.

Is any ongoing maintenance required?

For the first five years after installation, required maintenance is covered under workmanship and/or product warranties. Reputable installers work with the manufacturers to make sure warrantied parts are provided at no cost. We at Plymouth Solar Energy monitor each of our systems daily to identify possible component issues.
