Solar Power and Energy Storage

Common-area electricity is one of the largest long-term expenses for an estate. Yet the solar potential of rooftops, car park canopies and external walls often goes unused. We assess each estate's sun orientation, shading and existing electrical installation, and work out generation potential and payback period first — deciding whether and how large to build comes after the numbers, not before selling equipment.

The PV system is designed on a self-use-first, export-the-surplus basis: daytime generation supplies common-area loads directly (pumps, lifts, lighting, monitoring), reducing purchases from the grid, while surplus power can be sold under the government's Feed-in Tariff scheme, generating real income for the estate. Energy storage shifts daytime surplus to evening peaks, and doubles as backup support during outages.

The works are delivered by the group's licensed electrical team: structural assessment, inverter and distribution arrangements, lightning protection and earthing, through to completing the grid-connection application with the power company — one team accountable end to end. A generation monitoring platform lets the management office view daily and monthly output and savings, with the data feeding into the annual management report.

Maintenance and safety are long-term commitments: panel cleaning, inverter cooling, DC isolation and fire requirements all follow Electrical and Mechanical Services Department requirements, with periodic inspection reports filed with the owners' corporation. We also assess roof waterproofing and structural loading, and carry out the works without affecting the warranty obligations on the estate's original waterproofing layer.
