Commercial Solar Equipment Financing & Leasing

Choose the ownership model before comparing quotes

Under a power purchase agreement, the customer generally purchases power from a third-party-owned system; an equipment lease concerns use of the equipment. A financed purchase has its own ownership and repayment terms. The DOE decision guide explains these different models and the importance of local project conditions.

Do not compare a price per unit of electricity with an equipment payment as though they purchase the same rights. Consider escalation provisions, system output, operating responsibilities and the remaining obligations if the building is sold or the tenant moves.

Establish site control and utility requirements

Identify the roof, ground area or canopy involved and who has authority to permit installation. Consider the relationship between the system’s intended life and the building occupancy period. Roof condition, access and future repair plans can affect both project cost and timing.

Have the project team confirm applicable permitting, interconnection and utility arrangements for the actual site. Requirements and available ownership models vary. A contractor’s projected start date is not proof that the utility has accepted an interconnection request.

Separate installed equipment from development costs

An itemized scope can include modules, inverters, mounting systems, monitoring and electrical components, alongside design, construction and commissioning. Storage is a distinct technical and commercial component when included. Identify which supplier is responsible for the integrated system.

Request a milestone schedule covering orders, installation, inspections and permission to operate where applicable. Explain deposits already paid and when remaining amounts fall due. Financing availability must be reviewed against that schedule rather than assumed from the overall contract value.

Test project economics and end-of-term choices

Use a USD budget with independently reviewable assumptions for output, electricity prices, operating expenses and degradation. Do not deduct a projected incentive as though it were cash already received. Eligibility, ownership requirements and current tax treatment need transaction-specific advice.

For leased equipment or a PPA, read purchase, renewal, removal and transfer provisions. Who pays for roof access, equipment removal or a building sale can materially affect the comparison. For an owned system, maintenance and replacement of components still need funding over its life.
