Frequently Asked Questions

How much does a PV system cost?

Solar PV prices are at their lowest ever. A typical residential PV system costs about as much as an economy car. Because of current subsidies and incentive programs, your system can pay for itself in 5-7 years. Financing is available through local banks.

What incentives are currently available?

  • There is a 30% federal tax credit on the total cost of your PV installation.
  • Massachusetts offers a $1000 tax credit on your PV array.
  • Solar is property tax exempt
  • No sales tax on PV systems
  • 10-year window to earn SREC income based on energy produced

Can I sell back to the grid?

You can sell your SRECs to the utility company. A typical residential PV system will earn $1500 in SREC income per year. Credits for excess power produced by your system can be assigned to other households.

What’s an SREC?

An SREC is a Solar Renewable Energy Credit. You earn SRECs for the amount of electricity your PV system produces.  Your SRECs can be purchased by the utility company for no less than $300 each. 1 SREC = 1000kWh.

How will a PV system affect my house value or taxes?

A solar PV system will increase your home’s resale value and is exempt from additional property taxes.

What size system do I need?

This will depend on roof size, budget, and electrical usage. A typical residential PV system will cover 50% - 100% of your electrical usage and provide an additional source of income for up to ten years.

Will I still have solar power when there is a blackout?

Most PV systems shut down when the electrical grid is down. Battery backup systems and generators are available if you need power during power outages.

What will I have to do to maintain my system?

There is little to no maintenance required for PV systems. Rain will clean your PV array of dust, and snow will melt off quickly. Your system can be monitored via the internet and smartphone.

How long do solar PV systems last?

Solar PV systems are designed to last 25-30 years. Many PV systems installed in the 1980’s are still going strong.

What about insurance?

Most residential PV systems are covered under your existing homeowners policy. A small annual fee may be added.

If I can’t put solar on my roof, are there other options?

Yes. We offer ground mount, pole mount, carports, and tracker systems.
