When it comes to understanding solar energy, there are a number of things to consider.  This page provides info about SRECs, Federal Incentives, State Rebates & Policies, How Solar Works and much more. Can't find the information you're looking for? Contact us today!

Why Solar?

  •  To harness the power of the sun, a facility doesn't have to be the constructed with the latest high tech LEED methods.
  •  The system designs are proven and installation can be completed within three days. The best part is the payback begins as soon as the "switch is flipped" and you have the ability to monitor your system online.
  • State and Federal incentives are available to most everyone, whether you are a privately owned firm or a municipal facility.
  • State rebates are at an all time high. Between state and federal tax incentives, it is not uncommon to see a system pay for itself between four and seven years.
  • Solar electric systems typically last over 25 years and excess power it generates can get sold back to the grid.
  • New technology is being introduced almost weekly, so the system efficiency is increasing at an unprecedented rate.

City of Boston Interactive Solar Map

The Solar Boston map allows you to see active renewable energy installations within the city, and to calculate the solar potential of building rooftops. The map was created by the Boston Redevelopment Authority in cooperation with the Solar Boston program.


Solar Boston Permitting Guide

The Solar Boston Permitting Guide was developed as a resource for residents, businesses and solar installers to help navigate the solar project development process. Click on the links below to view specific chapters of the guide.

Solar Renewable Energy Certificates (SRECs)

In SREC states, the Renewable Portfolio Standard (RPS) requires electricity suppliers to secure a portion of their electricity from solar generators. The SREC program provides a means for Solar Renewable Energy Certificates (SRECs) to be created for every megawatt-hour of solar electricity created.

SRECTrade currently operates monthly auctions for SRECs in states where there are SREC markets.  The information on this page is general information describing how SREC programs work.  For information about your specific state program see the following links:

District of Columbia Ohio
Delaware Massachusetts
Maryland Pennsylvania
New Jersey

Distributed Energy Resources video

This video discusses the challenges, benefits, and technologies of distributed energy. Distributed energy, such as solar, refers to power-generating technologies that are placed at or near where the energy is consumed.


 American Recovery & Reinvestment Act 

In the face of an economic crisis, the magnitude of which we have not seen since the Great Depression, the American Recovery & Reinvestment Act represents a strategic, and significant, investment in our country's future.

The Act will save and create three to four million jobs, 90 percent of them in the private sector. It will provide more than $150 billion to low-income and vulnerable households -- spurring increased economic activity that will save and create more than one million jobs.

These measures are necessary to help the millions of families whose lives have been upended by the economic crisis. But, this Act will do more than provide short-term stimulus. By modernizing our health care, improving our schools, modernizing our infrastructure, and investing in the clean energy technologies of the future, the Act will lay the foundation for a robust and sustainable 21st century economy.


**(Note: early in the video, you'll hear the statement, "Every minute, enough of this [sunlight] energy reaches the Earth to meet the world's energy demand for a whole year." This statement is misleading if specific assumptions are not considered. A more accurate general statement is that "every hour enough of this energy...".)
