  • Build district-level installer and electrician networks, including training and certification programmes.
  • Offer zero- or low-down-payment solar loans through banks, NBFCs and microfinance partners.
  • Bundle rooftop solar, battery storage, smart energy monitoring and maintenance into standardized household packages.
  • Run village demonstration projects through CSR channels to establish trust and generate local referral demand.
