About this Initiative

With a click, the Cambridge Solar Tool shows Cambridge residents, businesses, and property owners how much electricity can be produced on their rooftops from solar photovoltaic (PV) systems, how the financial investment will pay off, and how much pollution will be reduced.

Solar energy is a key strategy for Cambridge to reduce greenhouse gas emissions and make the community more resilient to the impacts of climate change. To promote solar installations the City of Cambridge worked with Mapdwell to develop The Solar Tool.

Mapdwell developed the solar potential data delivered and visualized through Solar System as well as the complete cost/benefit analysis modules, while the City of Cambridge provided the underlying input datasets, content, and imagery.

The City of Cambridge intends to regularly update the tool to reflect changing market conditions and financial incentives. Please note that the PV market is very dynamic and some assumptions may at times not be entirely up to date, given the ever-changing reality of the market.

The Cambridge Energy Alliance (CEA) program assists the community in taking the next steps toward installing a PV system. Please contact CEA with renewable energy and energy efficiency related questions.

Four Easy Steps to Install Solar on your building:

  1. Find your potential on the Cambridge Solar Tool
  2. Contact installers to get a free site assessment and quote
  3. Decide to lease or own the solar panels
  4. Install and reap the benefits

Installers help you select the best system(s), guide you through the application process for incentives, and answer any questions you may have about how best to proceed.

There is not a recommended or "approved" list of solar installers in Massachusetts. A useful set of questions and resources are available from the Massachusetts Clean Energy Center (MassCEC). Please contact the Cambridge Energy Alliance with any energy related questions, from efficiency to solar.
