Path-Q Solar

How should I compare solar financing when payments begin before the system is producing electricity?

Answer

Compare financing based on the full cash-flow timeline, including payments made before operation, construction delays, and the date savings actually begin. A loan with earlier payments may cost more during the non-producing period even if its stated rate or payment appears lower.

Key points

  • Identify the first payment date, expected permission-to-operate date, and any interest accrued during construction.
  • Model delayed completion, delayed interconnection, and the possibility that savings begin later than promised.
  • Compare total payments, fees, rate structure, prepayment terms, and the effect of any promotional period.

What it depends on

  • Loan disbursement and payment schedule
  • Construction and interconnection timeline
  • Whether interest accrues before production
  • System output, bill savings, and delay remedies

Risks and trade-offs

  • The homeowner may carry both loan payments and the existing electricity bill during delays.
  • Variable rates or deferred-interest features can change the actual cost.
  • A provider's production guarantee may not compensate for all financing or delay costs.

Information you may need

  • Financing agreement and amortization schedule
  • Estimated installation and interconnection milestones
  • Delay, cancellation, and payment-adjustment provisions
  • Expected utility bill during the construction period

Your next step
