text: Accounts Receivable and Allowance for Doubtful Accounts 
  
  Depending on the day of the week on which the end of a fiscal quarter falls, our accounts receivable balance may 
  
  fluctuate as we are waiting for certain customer payments to clear through our banking institutions and receipts of payments 
  from our financing partners, which can take up to approximately two weeks based on the contractual payment terms with such 
  partners. Our accounts receivable balances associated with sales of energy storage products are dependent on billing milestones 
  and payment terms negotiated for each contract, and our accounts receivable balances associated with our sales of regulatory 
  credits are dependent on contractual payment terms. Additionally, government rebates can take up to a year or more to be 
  collected depending on the customary processing timelines of the specific jurisdictions issuing them. These various factors may 
  have a significant impact on our accounts receivable balance from period to period. As of September 30, 2024 and 
  December 31, 2023, government rebates receivable was $315 million and $378 million, respectively, in Accounts receivable, 
  net for the current portion and an immaterial amount and $207 million, respectively, in Other non-current assets for the long- 
  term portion in our consolidated balance sheets.
