Who handles SunStrong Management accounts now

SunStrong Management manages billing, customer service, and system operations for many former SunPower and Sunnova leases and PPAs, and some loans, on behalf of the system and contract owners (for Sunnova, Solaris Assets). SunStrong's account page sends homeowners to the billing portal tied to the original company (SunPower, Sunnova, PosiGen, or GoodLeap), so the owner of the contract or loan, and the holder of the UCC filing, can differ by account.

What it means for homeowners

  • SunStrong is generally the manager, not always the owner, of your contract; your lease, PPA, or loan terms stay the same unless the owner changes them in writing.
  • Pay through the billing portal SunStrong lists for your original company, and keep records of every payment during the transition.
  • SunStrong asks homeowners selling a home to tell it as soon as possible using the Sell or refinance my home option on its inquiry form.
  • SunStrong's site does not explain buyouts, payoffs, or UCC filing releases, so request these in writing and ask who the contract owner is.
  • Connecticut's AG reported complaints about system transfers and a $10 monthly fee for production data; complaints can go to your state AG or consumer protection agency.
