Shared areas in an apartment building can include lighting, pumps, security equipment and lifts. A solar project should begin by identifying the meter, ownership arrangement and loads included in the proposed scope.
Separate shared and individual consumption
Review which equipment is connected to common supplies and which belongs to individual apartments. Collect the relevant bills and operating schedules. Any discussion about allocating benefits or costs should be documented by the building’s decision makers before a system is ordered.
Coordinate access and responsibility
Roof access, maintenance routes and equipment locations affect residents as well as installers. Ask for a proposal that clearly identifies the served circuits, support contact and handover responsibilities. Special equipment such as lifts requires its own technical assessment rather than a general household assumption.
Define the shared loads and who owns them
Separate corridor lighting, pumps, security equipment and any lifts in the project brief. Confirm which meter supplies each service and who can authorise roof and electrical work. A shared system needs clear responsibility for monitoring, maintenance and cost allocation. Specialist loads such as lifts should receive their own assessment; do not assume that ordinary lighting backup is suitable for them.
Your practical checklist
- Identify common-area meters and loads
- Agree who approves installation and maintenance
- Keep resident access and roof use in the project plan
Can one rooftop installation automatically serve every apartment?
No. Metering, electrical boundaries and the agreed ownership arrangement must be established first.
