PPA carries no CAPEX exposure and no asset on the school's balance sheet; CAPEX-funded solar (with PSDS or Mayoral Renewables grant) returns a faster payback but ties up capital and adds an asset to maintain.
Solar for Schools PPAs commonly run 15 to 25 years with buy-out clauses at defined milestones. The buy-out price is index-linked and depreciates over the term.
Solar for Schools publishes installed-kWp and case-study data on its site, which can be used as a comparator for any new PPA negotiation.
