Planning solar for compound houses in Ghana

A compound house may contain several households, shared pumps, security lights, gates and common spaces. A single system can serve common needs or selected occupants, but unclear boundaries often create technical and financial disputes.

Decide what is shared

Start with common services such as water pumping, security lighting, gates and communications. If household loads are included, define the circuits and limits for each dwelling rather than relying on informal use.

Measure and allocate fairly

Sub-metering or monitored circuits can show who uses energy and help allocate operating costs. The arrangement should address new tenants, additional appliances and users who do not contribute.

Design for diversity and surge

Households do not always use appliances at the same time, but coincident cooking, ironing, pumping or refrigeration can create peaks. A load study should test realistic simultaneous demand and starting currents.

Assign responsibility

Document who owns the equipment, holds warranties, approves changes, pays for maintenance and authorises technician access. Provide labels and operating rules that every household can understand.

For a compound house, governance is part of the power system.
