Commercial

Put your building to work.

Solar and storage for working buildings.

Illustrative Australian logistics building with rooftop PV and loading forecourt

Evaluate the opportunity against the operation.

Commercial PV and storage need an operating case as well as a roof layout. Daytime loads, connection capacity and delivery constraints shape the opportunity.

Which data matters most?

Interval electricity use and operating hours help distinguish steady daytime demand, short peaks and seasonal loads. Add current tariffs and export conditions before assessing an operating or financial scenario.

What could limit the project?

Roof condition and structure, access and fire/service zones, switchboard capacity and network connection requirements. Identify tenancy, lease and ownership responsibilities before assuming the roof or electrical system can be altered.

How should proposals be compared?

Use the same load data and tariff assumptions. Compare scope, generation estimates, export assumptions, equipment, monitoring, maintenance and disruption. A generic payback figure is not a substitute for a site-specific assessment.

Technical details.

System integration

Generation joins the working building.

PV inverters connect to main distribution, which serves tenancy and plant loads. The grid and optional storage connect at the distribution system, not through the loads themselves.

System connections

From generation to building use.

Illustrative building energy connectionsAn illustrative electrical topology: PV array supplies an inverter through a DC route. The inverter supplies AC to the switchboard. Building loads and the grid connect separately to that switchboard. Optional AC-coupled storage has a separate battery inverter connection.

Design notes

Storage is shown as a separate AC-coupled branch. Metering, protection and isolation are omitted. Backup requires a separately designed arrangement. This is not a construction drawing.

Design considerations

Design around the operation.

A commercial roof can be an energy asset, but the opportunity depends on the load beneath it. Process equipment, tenancy patterns and delivery constraints make every site different.

Demand profile

Operating hours, interval data, HVAC and process loads inform generation and storage decisions.

Roof & connection

Structure, roof condition, access, switchboard capacity and network requirements define feasibility.

Delivery & evaluation

Assess project-specific costs, sequencing and business disruption using confirmed site data.

FAQs & enquiry checklist
Can the website estimate a project’s return?

A useful financial assessment needs actual energy use, tariffs, system scope, costs and connection conditions. SOLNEX does not present generic estimates as project outcomes.
