Path-Q Solar

Should a landlord include tenants' future electricity use when planning solar for a rental property?

Answer

Include credible future tenant electricity use only for the meters and loads the solar system can actually serve, and distinguish landlord-paid from tenant-paid electricity. The design should reflect expected occupancy, appliances, building upgrades, and turnover, but avoid paying for speculative demand unless expansion is difficult and the economics support planning ahead.

Key points

  • First determine who receives the solar benefit and who pays the electricity bill.
  • Tenant-controlled loads may vary more than common-area or landlord-controlled loads.
  • Electrification, added units, appliance changes, and occupancy changes can materially alter future demand.
  • Submetering, shared meters, and allocation arrangements can affect how benefits and responsibilities are handled.

What it depends on

  • Meter configuration and who pays each electricity bill
  • Lease structure, occupancy, appliances, and tenant turnover
  • Planned building improvements or electrification
  • Solar allocation, monitoring, and cost-recovery arrangement

Risks and trade-offs

  • Sizing to one tenant's behavior may not represent future occupants.
  • A landlord may bear installation costs while tenants receive most energy savings unless the arrangement is planned.
  • Over-sizing tenant-serving solar can increase cost if occupancy or usage falls.

Information you may need

  • Meter and panel schedules
  • Historical consumption by unit and common area
  • Lease and utility-payment arrangements
  • Planned renovations, equipment changes, and occupancy assumptions

Your next step

What to do next

Map each meter, payer, and load, then ask for separate current-use and future-use solar scenarios tied to the property's expected ownership and cost-recovery arrangement.
