Advantages of owning your own solar power system (versus leasing)

There is a big push now from larger corporations such as solar companies to lease people’s roofs and other suitable space because this is a high return investment (for them) especially in Massachusetts. However, if you own your own PV system:

  • Up 30% of total cost can be used as an income tax credit.
  • Collect Solar Renewable Energy Credits (SRECs) for 10 years. Actual payback depends on production and market price; average credit $2,000/year.
  • Never pay for electricity again; become invulnerable to price changes.
  • Businesses can deduct the installation as business expense.

Own your own system and put the profits in your own pocket.


We are now a Mass Solar Loan approved installer.

Incentives to help Massachusetts residents go solar by purchasing their own PV system:

  • Low-interest, fixed-rate loans
  • Loan support for qualified residents

Domestic DC Systems designs and installs:

Grid-tied PV systems

A photovoltaic (PV) system that generates electricity with solar panels. Grid-tied systems are interconnected with the power grid through a grid interactive inverter. Electricity can flow TO or FROM the power grid depending on your needs and production.

Battery based back-up systems

Critical appliances are powered from a battery bank during power outages. Batteries are charged from 1 or more of the following sources: grid, generator, solar panels.

Bi-modal systems (grid-tied and battery back-up)

Best of both worlds. Combination of grid-tied system with battery based systems. Will always power your appliances even during a grid outage. Extra energy will be "stored’" on the power grid.

AC and DC coupling

Battery-based retrofit for existing grid-tied systems to work during a power outage.

We provide:

  • Installation of PV and battery backup systems for homeowners and small businesses.
  • Service and maintenance (check system for proper functioning once a year).
  • Retrofitting existing grid-tied systems with battery backup.
  • Free initial estimates.
