Path-Q Solar
What grid approval risk does a landlord face when one solar system serves multiple tenant meters?
Answer
The landlord may face approval, metering, ownership, allocation, and interconnection complications because one generating system is connected to multiple customer accounts. The project may require a specific approved arrangement, additional studies or equipment, separate agreements, or may not be allowed as designed under the serving utility's current rules.
Key points
- Determine whether generation will be behind one meter, allocated across meters, or delivered through an approved shared arrangement.
- Confirm who is the interconnection applicant, account holder, generator owner, and beneficiary of credits or savings.
- Ask whether separate meters require additional metering, controls, protection, or billing arrangements.
- Build approval timelines and redesign risk into the project schedule and budget.
- Do not rely on an installer's verbal statement that multi-meter allocation is permitted.
What it depends on
- Utility territory and current interconnection rules
- Meter configuration and ownership
- Proposed energy allocation and billing model
- System size and export profile
- Building and electrical design
Risks and trade-offs
- A technically feasible design may still fail a utility's program or customer-eligibility rules.
- Approval delays can affect tenant expectations, financing, and construction timing.
- Allocation errors can create billing disputes among tenants.
- Redesign or additional metering can materially increase cost.
Information you may need
- Utility and meter account details
- Single-line diagram and proposed allocation method
- Current interconnection and shared-generation requirements
- Installer's approval history for comparable projects
- Written utility pre-screen or feasibility response
