Solar Resources

Thinking about going solar? Here, you’ll find knowledge and tools to help make informed decisions about solar for your home or business. Whether you’re curious about savings or want to dive deeper into non-carbon energy, we’re ready to help you harness the power of the sun with confidence.

Selecting an Installer

Once you've decided solar is right for you, your next step is to get comparative quotes to select an installer.

The Massachusetts Clean Energy Center (MassCEC) Solar Costs Comparison Tool is a database of solar installers that have completed projects in Massachusetts. The tool can be filtered by county and provides the name of the installer, their median cost per watt, and the number of projects they've completed. The data is curated and maintained by the Mass CEC.

Your selected solar installer will help you determine the size of the system based on your electricity usage and other factors. RMLD also recommends that you:

• Always check the installer's references.
• Verify that the installer is properly licensed by checking the MA Home Improvement Contractor Registry or the MA ePlace Portal.
• Ensure the installer is bonded and insured.

Are you a large municipal or commercial customers issuing a Request for Proposal (RFP)? The U.S. Department of Energy has created a Solar PV RFP Template that can be customized.

RMLD does not endorse or recommend contractors and recommends that you solicit at least three competitive quotes. 

What Happens to Excess Electricity?

When your solar system produces more electricity than your home will use, you will be credited the monthly fuel charge per kWh for excess electricity fed into RMLD's distribution system. The fuel charge is the only kWh charge that RMLD credits back for solar. This charge is update monthly on the RMLD Monthly Rate Adjustments page.
