Cost and Performance

The cost of buying a solar electric system can vary based on system size, location, equipment used and other factors. Though MassCEC cannot say what a "good" price is for your solar electric system, we can help you see what others are paying for solar projects around the Commonwealth.

Incentives and Programs

Residents and business owners can benefit from a number of programs aimed at making solar electricity more affordable to install, including state and federal tax credits. Below is a quick breakdown of incentives currently available for installing residential and commercial solar electric systems. More information on incentives for clean energy projects can be found at the Database of State Incentives for Renewables and Efficiency (DSIRE).

How It Works

Solar electric systems, also known as solar photovoltaics or solar PV, convert sunlight into electrical energy through an array of solar panels that connect to a building's electrical system or directly to the electrical grid.

Solar electricity is often a cost-effective way for homeowners, businesses and municipalities to reduce their energy costs, while also reducing their environmental impact. As you consider whether solar electricity is right for your home or business, you can familiarize yourself with how the technology works.

MassCEC’s support was integral to deploying Needham-based SolarOne Solution’s next generation of solar-powered street lights in a “living-lab” environment, collecting real-world data and community feedback and facilitating real-time adjustments.  SolarOne’s lights re-lit a dark section of Somerville’s Community Bike Path, which sees roughly 500 bike riders per day.  

City of Gardner Receives Grant for New Turbine

One of the challenges of implementing renewable energy is ensuring consistent energy availability. Wind speeds are not always fast enough for turbines to generate energy, and solar PV panels can only generate electricity when the sun is shining. Numerous solutions are in the works, from batteries that can store the energy until it is needed, to the coupling of clean energy with traditional fuels when wind or solar resources cannot match electrical demand.
