Connected Solutions is summer-only, at least in MA. That said, as a person with Tesla solar and a Powerwall on order who is also enrolling in Connected Solutions for next year and given the electric supply tightness ISO New England is expecting this winter due to natural gas woes, I'm kind of surprised that there isn't talk/interest of adding a winter season too. It may be that power problems in the summer tend to be confined to a very few hours in the afternoon, while winter shortages tend to last several days, accompanying the more severe cold spells. That and perhaps people don't want to let their KWh out given the shorter solar generation days of winter.
