First Step - Selecting an Installer

If you've reviewed the basics and decided solar may be right for you, you're ready to take the first step: getting quotes and selecting an installer.

To get started, you should contact a licensed solar installer in Connecticut. The installer will work with you to design your system and submit your application to Groton Utilities.

The Connecticut Green Bank maintains a database of contractors that they have approved as registered or eligible to offer the various green solutions promoted by the Green Bank.

The tool can be filtered by name, address, solution, service, or product.  Click here for CT Green Bank's Solar Contractor Tool.

It is recommended that you solicit at least three competitive quotes. The installer will determine the recommended size of the system based on your electricity usage.

Once you've received quotes, the following steps are recommended:

• Check installer's references
• Verify that installer is properly licensed
• Make sure installer is bonded and insured

System size limit:

• Your solar installer will provide you with a system size recommendation based on your highest average annual consumption over the last 5 years. 
• You may request additional allowance for the standard expected kWh of up to two electric vehicles and a whole-home heat pump system, as listed here: 
  • Electric vehicle (per vehicle): 3,285 kWh  
  • Whole-home air source heat pump: 3,608 kWh 
  • Whole-home ground source heat pump: 2,458 kWh
