Commercial solar is one of the most effective ways for Perth businesses to reduce operating costs and gain more control over rising electricity prices. Ultima Solar designs and installs solar PV systems for businesses across Perth and Western Australia, with solutions tailored to your consumption profile, roof space, tariff structure and long-term energy goals.
We work with businesses that need more than a generic solar quote. Your system should be designed around when you use power, how your demand charges behave, how much export the network will allow, and whether battery storage or EV charging should be planned from day one.
Energy analysis
We review bills, interval data, tariffs and demand peaks before recommending a system size.
Commercial design
Panel layout, inverter selection, export limits, switchboard capacity and future upgrades are considered from the start.
Install and support
We manage installation, commissioning, monitoring and ongoing maintenance support.

How large should a commercial solar system be?
The right size depends on your daytime consumption, roof space, tariff, demand profile, export limits and growth plans. Many small and medium commercial systems sit between 20 kW and 100 kW, while larger sites may need a staged or large-scale design.
Can my business add batteries later?
Yes, but it is better to consider battery readiness during the solar design stage. Inverter selection, switchboard capacity, space allocation and monitoring architecture can all affect future battery integration.
