For our Massachusetts Customers regarding MA SREC systems:

If your system electronically reports production to MassCEC, you MUST determine if communication is by cellular or internet. If cellular, you MUST take action in order to continue earning SRECs.  Please read this entire letter to learn more about the required next steps.

In 2022 all cellular carriers are shutting off the 2G and 3G cellular infrastructure needed to operate devices based on that technology. Once the 2G/3G network is turned off, those devices will no longer automatically report production. Without reporting, SRECs will not be created and you will not receive payments.

Please note that each carrier has a different shut-off date. Plans and timing to phase out 3G services will vary by company and may change. Your installer should be able to tell you which carrier you are using.

AT&T will finish shutting down its 3G network by February 2022.

T-Mobile will finish shutting down its 3G network by March 31, 2022.

Verizon will finish shutting down its 3G network by December 31, 2022.

If your installer has already replaced your 2G/3G meter or is scheduled to do so, please notify us by emailing amy@knollwoodenergy.com.

If you are just learning of this issue now, please continue reading. To ensure your SREC payments continue, you have 2 choices for reporting.

CHOICE 1 – Switch to Manual Reporting

If your system capacity is smaller than 25 kW, the easiest option and one that will require no financial outlay is to switch from automatic reporting to self-reporting.  

Requirements for Manual Reporting

1. You must be able to read the physical solar production meter, log into your MassCEC account and enter the meter reading. Reporting into the MassCEC Production Tracking System is done monthly and takes very little time to do. It is NOT the same meter as the utility company’s net meter.  

1. Reply to Amy@Knollwoodenergy.com that you want to switch to manual reporting and she will notify MassCEC to change your account. MassCEC will send you instructions on how to report your meter reading to PTS. You will use the same username and password you currently use to log into PTS.

CHOICE 2 – Continue Automatic Reporting

If you want to continue auto-reporting, you MUST contact your installer to learn of your options, which may include the following:

1. Hardwire- If available, the metering system may be able to be hardwired into the internet and avoid using cellular services going forward.
2. Meter Replacement- a new 4G meter can be installed.

Notify jessica@knollwoodenergy.com as soon as the meter is switched to ensure reporting continues. We will need to know the date the meter was changed and the last reading on the old meter so you don’t lose any credit when the meter is changed.

If it will take several months to replace the meter, we recommend that you switch to manual reporting until the meter swap has been completed.

If your original installer is no longer in business, we can suggest the following MA installers:
