Commercial solar for your business

Power up your business with commercial solar

Investing in solar is one of the smartest decisions your business can make. High energy consumption during peak daytime hours can send power bills soaring, and with electricity prices rising, managing costs can feel impossible.

Solar power puts you in control, reducing overheads and boosting energy efficiency. For landlords, it’s also an opportunity to charge tenants for the solar energy they use through a clear, usage-based system—helping you recoup your investment while providing tenants with cost-effective, clean power.

It’s not just about savings—solar makes your property more attractive to eco-conscious tenants, adds long-term value, and positions your business as a leader in sustainability.

How solar works

Commercial building solar

1

Solar panels convert sunlight into DC electricity for your commercial building. 



2

Inverters convert DC into 230V AC and send it to the buildings switchboard. 



3

Switchboards distribute electricity throughout your commercial building supplying power to each tenant.


4

Tenant meters measure the individual power consumption of each tenant. 

 

5

The building owner's Billing System tracks each tenants power usage and ensures clear billing for each.



6

A Revenue Stream is generated for the building owner by billing tenants for the power they consume.
