Solar on Leased Business Premises: Questions for Tenants and Landlords

Can a business install solar on a leased building?

Solar can be worth evaluating, but settle three questions before committing: who has the right to use the roof, whose electricity account benefits, and what happens when the tenant leaves? Ask for written site rights, an agreed billing arrangement, and contracts that address lease expiry, roof work and removal. A promising electricity-savings forecast does not resolve those issues.

This guide is for U.S. commercial premises. New York City permitting and California utility arrangements appear as examples, not nationwide rules. Use the project’s actual state, municipality and utility territory when checking requirements.

1. Establish roof rights and obtain the necessary consent

Start with the property lease—not a panel layout. Ask your property lawyer to review the description of the leased premises, alterations provisions, access rights and end-of-lease obligations. Do not assume that renting the space beneath a roof gives the tenant permission to install equipment above it.

Prepare a site-rights plan covering:

• The roof area proposed for panels.
• Space for inverters, disconnects and other equipment.
• Cable routes through shared or landlord-controlled areas.
• Access for surveys, construction, maintenance and emergencies.
• Temporary staging areas and any restrictions on working hours.
• Arrangements for other roof users, including HVAC contractors.

Seek written agreement on these points before authorizing substantial project spending. Ask counsel whether a lease amendment, separate roof agreement or agreement involving the solar provider is appropriate, and whether any lender or other party must also consent.

Landlord consent and public approvals are separate checks. In New York City, the Department of Buildings’ solar checklist says the property owner’s signature or consent is required for the design professional’s project application. Its owner requirements also call for professional construction documents, structural analysis and separately permitted electrical work. These are local requirements; obtain the equivalent checklist from your own authority. (home4.nyc.gov)

A useful first deliverable is a marked-up plan showing proposed equipment and access routes, accompanied by a written statement of which parties must approve each area.

2. Identify the meter and the route to savings

Ask the designer to produce a simple diagram showing the solar connection point, utility meters, account holders and loads served. Then ask the utility to confirm the proposed billing arrangement.

A roof location alone is not enough to establish which tenant will receive a financial benefit. For example, PG&E describes virtual arrangements in which an owner or manager allocates percentages of exported generation to eligible benefiting accounts. The allocation is part of a defined utility program—not simply a private promise to share savings. (pge.com)

Use these questions to investigate the arrangement:

Proposed arrangement	What to establish before modeling savings
Solar connected behind the tenant’s meter	Account holder, connection approval, applicable tariff and treatment when the tenant moves
Solar connected to a landlord or common-area account	How any tenant benefit will appear in rent, service charges or another agreed calculation
Landlord master meter with tenant submetering	Applicable supply and billing rules, measurement method and allocation formula
Separate generator account allocating credits	Program eligibility, credit allocation, administrative charges and procedures for changing tenants

Do not use an old net-metering example as evidence of current eligibility. PG&E’s current guidance says its standard NEMV, NEM2V and NEMVMASH programs are closed to new applications and directs applicants to the Virtual Net Billing Tariff. Check the applicable tariff rather than relying on the program name alone. (pge.com)

For a practical check, request a sample monthly reconciliation: utility charges, solar payments, allocated credits and any landlord charges. Every claimed saving should have an identifiable recipient and calculation.

3. Separate building ownership, equipment ownership and electricity purchases

Treat these as three different questions:

1. Who owns the property?
2. Who owns the solar equipment?
3. Who buys its electricity?

For evaluation purposes, compare tenant-owned, landlord-owned and third-party-owned proposals. Do not assume they place the same obligations on the parties.

Under a solar power purchase agreement, or PPA, a third-party provider owns, operates and maintains the system, while the host customer purchases its electricity for an agreed period. That describes the basic structure; the actual agreement still needs careful review. (epa.gov)

Ask each proposal to state:

• Who owns panels, mounting equipment, wiring and replacement components.
• Which items, if any, become landlord-owned improvements.
• Who pays for monitoring, maintenance, repairs and insurance.
• Whether equipment can be transferred, purchased or removed.
• Who receives export payments and other financial benefits.
• Who owns renewable energy certificates, or RECs.

Keep the environmental claim separate from the electricity payment. DOE explains that selling a project’s RECs limits the host’s ability to claim use of the associated renewable electricity. Do not let the tenant and landlord both make claims based on attributes neither has retained. (energy.gov)

Also check whether the proposed sale of electricity is permitted locally. DOE notes that third-party onsite electricity sales are not allowed in every state and utility territory. Ask counsel to confirm the rules for the specific transaction, including any landlord-to-tenant billing arrangement. (energy.gov)

4. Match the property lease to the solar commitment

Put all relevant dates on one timeline:

• Property lease expiry and renewal-option deadlines.
• Expected installation and operating dates.
• Solar payment or financing term.
• Site-access term.
• Planned roof replacement.
• Purchase-option and removal deadlines.

Distinguish a hoped-for renewal from an enforceable right to renew. Ask counsel what conditions apply to any option and whether the solar agreements remain workable if it is not exercised.

Worked example: a short lease and a longer PPA

Assume, solely for discussion:

• A tenant has five years remaining on its property lease.
• Project development and installation take one year.
• A proposed PPA runs for 15 years from operation.
• The tenant has not secured additional occupancy or a release from later obligations.

At operation, the tenant has four years of occupancy remaining. The PPA therefore extends 11 years beyond the property lease: 15 − 4 = 11.

This is a timeline illustration, not a production forecast or financial estimate. It shows why the parties should resolve the mismatch before signing.

Possible negotiating routes include extending occupancy, making the landlord the long-term purchaser, or arranging an approved transfer or buyout mechanism. None should be assumed available. Obtain written terms explaining who takes responsibility if the tenant leaves and whether provider approval is required.

Ask for separate scenarios for staying, leaving at expiry and leaving early. Include any quoted termination, transfer or removal costs rather than treating future electricity savings as a substitute for an exit plan.

5. Agree on roof repairs and interruption costs

Before selecting a layout, ask the landlord for roof records and arrange a qualified assessment of condition, structural suitability and anticipated repair needs. In New York City, the structural analysis required for solar work must determine whether the existing structure can support the added panel weight. Do not substitute a sales estimate for the necessary professional review. (nyc.gov)

Request written answers to two different issues:

• Roof condition: Is repair or replacement needed before installation?
• Contract responsibility: Who pays when roof work requires solar equipment to be moved?

The roof-work provisions should address:

• Notice periods and emergency access.
• Who diagnoses leaks and authorizes repairs.
• Responsibility for installation-related damage.
• Removal, storage, reinstallation and recommissioning.
• Whether solar payments continue during interruption.
• How any compensation is calculated and limited.
• Roof-warranty conditions and required approvals.

Ask for a costed approach to any already-planned roof replacement. “We will handle it later” is not a useful allocation of responsibility.

Check emergency access as well as maintenance access. New York City’s rooftop-access guidance explains that rooftop solar must be considered alongside fire-service access requirements and identifies circumstances requiring a variance application. Have the design team establish the applicable local pathways and clearances before treating the whole roof as usable space.

6. Define the exit before installation

Ask your advisers to test the agreements against specific events, rather than relying on a general promise that the system is transferable:

• The property lease expires without renewal.
• The tenant closes, relocates or assigns its lease.
• The landlord sells the building.
• A casualty damages the roof or equipment.
• The solar provider defaults or ceases operating.
• The site becomes vacant or its electricity demand changes.

For each event, identify who owns the equipment, who owes payments, who retains access, and which approvals are needed.

If removal is required, specify the responsible party, deadline, restoration standard and treatment of cables, penetrations and abandoned equipment. Ask whether security for removal and restoration costs is appropriate. If equipment remains, document the transfer terms and responsibility for inspection, warranties and future maintenance.

Also request a vacancy scenario. Ask who pays for solar electricity when the intended purchaser has left, and how any export revenue would be treated under the applicable tariff.

Finally, clarify the handover package: operating manuals, monitoring access, inspection records, warranty documents, utility correspondence and emergency contacts. Make delivery of that package an explicit project-closeout requirement.

7. Use a tenant–landlord checklist before procurement

Hold an initial meeting with the tenant, landlord, facilities representative and finance lead. Bring in property counsel, a qualified solar designer and utility representatives as the questions become specific.

Use this checklist to assign decisions and missing evidence:

Question	Evidence or decision to request
Who controls the roof and equipment spaces?	Lease review, site plan and written access terms
Whose bill benefits?	Meter diagram, account details and tariff confirmation
Who owns and pays for the system?	Ownership schedule and proposed commercial agreements
Does occupancy cover the commitment?	Timeline and stay/leave scenarios
Is the roof suitable?	Condition records and professional assessment
Who pays during roof work?	Repair and interruption provisions
What happens at exit?	Transfer, buyout, removal and restoration terms
Who receives environmental attributes?	REC ownership and permitted-claims provisions
Which approvals remain outstanding?	Consent, permit, inspection and interconnection register

Keep the approval register separate from the commercial checklist. For example, PG&E’s virtual-tariff process requires an interconnection application and specified final documents before written permission to operate. A landlord’s approval does not replace those utility steps. (pge.com)

Common mistakes to flag are counting unagreed renewals, assigning savings to the wrong meter, leaving roof-work costs undefined, and assuming departure automatically ends solar payments.

The next step is not necessarily a binding solar contract. First assemble the lease documents, electricity records, roof information and a proposed responsibility schedule. Proceed to detailed procurement when the parties can explain—in writing—who benefits, who carries each obligation and how the arrangement survives a change of tenant.
