Path-Q Solar

How might a solar tax credit affect the financial comparison between a lease and a cash purchase?

Answer

A credit can improve the economics of a cash purchase if the purchaser is eligible and can use it, while a lease may place the incentive with the system owner and reflect its value indirectly in the contract price. Compare the complete after-incentive cash flows rather than assuming the credit belongs to the customer under both options.

Key points

  • Identify who owns the system and who is entitled to each incentive.
  • For a purchase, test whether the buyer has sufficient eligible tax liability and meets all conditions.
  • For a lease, examine whether incentive value is reflected in payments, escalators, buyout terms, or provider pricing.
  • Include maintenance, degradation, roof work, transfer, removal, and end-of-term obligations.

What it depends on

  • Current tax-credit rules
  • Ownership and financing structure
  • Lease payment and escalator terms
  • Installed price, operating costs, and expected bill savings

Risks and trade-offs

  • A headline tax credit can be unusable or delayed for a purchaser.
  • A lease can reduce upfront cost but may limit control, transferability, or long-term savings.
  • Comparing pre-incentive purchase cost with post-incentive lease economics is misleading.

Information you may need

  • Cash-purchase price and financing terms
  • Full lease or power-purchase agreement
  • Current incentive eligibility and timing
  • Taxpayer ability to use the credit
  • Transfer, maintenance, and end-of-term terms

What to do next

Request side-by-side after-incentive cash-flow models using identical production and bill assumptions, then verify the tax treatment independently.
