This page was created by students from Worcester Polytechnic Institute working with the Town's Energy Office on a research project examining local solar-PV adoption on Nantucket. The team spent seven weeks on Nantucket learning about the unique challenges of installing solar photovoltaics on island as part of a Interactive Qualifying Project ( report can be found here. During our time on Nantucket, we interviewed residents who own solar PV systems, interviewed solar installers, sent a survey out to residents about solar PV, and created a database of solar installations on Nantucket. With the information we gained, we created this webpage to be used by the Town of Nantucket Energy Office to educate the public about installing solar PV on Nantucket.
This map shows all of the solar PV installations on Nantucket. Interact with the map to learn more about each installation.
This map consolidates information about residential solar PV, commercial solar PV and solar hot water, and is maintained by the Energy Office.
The installers listed in the map have operated on Nantucket. This serves in no way, shape, or form as an endorsement for these installers.
Photovoltaics (PV) use solar panels made of semiconductors to generate electricity from sunlight. This energy is converted into electricity where it can be used to power electric devices or power the electric grid. The cost of photovoltaics has drastically decreased over the past decade as the technologies have been refined to maximize efficiency and lower manufacturing costs while local, state, and federal governments have all passed rebates to promote the installation of photovoltaics. Photovoltaic systems can be mounted to your roof, or installed on the ground as a fixed array, or installed on the ground to track the sun.

Illustrated to the left is a graph showing the number of residential solar PV systems (shown in blue) and the number of commercial solar PV systems (shown in red) installed from 2007 to 2017. This graphic does not include solar hot water systems.
Described to the left is the local permitting process that every person has to follow when installing a solar PV system. These can be done by an installer or by the homeowner. The time for each step is an estimate and may change depending on the situation.
