Commercial & Large Scale Solar
Commercial Solar Sydney & Regional NSW
Engineering-Led Systems Built to Perform Under Real Grid Conditions
For CFOs managing assets across Sydney metro portfolios, and for landowners operating high-load sites across regional NSW, the risk today is not paying too much. It is installing a system that quietly underperforms for the next 20 years.
At Opera Solar, we design commercial solar as infrastructure. That means engineering first, safety before speed, and financial modelling grounded in how the grid actually behaves, not how it behaved five years ago.

Frequently Asked Questions
There is no universal size. We assess your electricity demand, operating profile, roof, network conditions and future requirements before recommending capacity.
It depends on how your business consumes energy and the economics of storage. We assess battery storage as part of the overall system rather than assuming it is required.
Yes, where the site and project requirements support an upgrade, expansion or battery integration. The existing system and network conditions need to be assessed first.
Installation planning is designed around how the site operates. Where electrical work or access needs to affect operations, it should be planned with the business in advance.
An electricity bill is one of the most useful starting points because it helps us understand energy costs and consumption. Additional site information can improve the assessment.
Eligible NSW businesses may qualify for the battery incentive for systems from 20 kWh to 30 MWh. Eligibility and the actual discount depend on the project, equipment, installation and program requirements.
Commercial Solar Designed Around Your Business
The Cheapest Solar Quote Can Become the Most Expensive System
A commercial solar system is a long-term business asset. The price on the proposal is only one part of the decision. If a system is oversized for your actual daytime demand, limited by network export conditions, affected by voltage behaviour or poorly matched to how your business operates, the headline system size may not translate into the savings you expected.
That’s why we start with the site, the energy profile and the network — before recommending system capacity.
Before You Commit to Panels, Inverters or Batteries
We assess the commercial opportunity behind the project first.
- 01Your electricity consumption and operating profile
- 02Solar self-consumption potential
- 03Existing solar and future energy requirements
- 04Network connection and export considerations
- 05Voltage and grid constraints
- 06Roof structure and available installation area
- 07Battery storage opportunities
- 08Future EV charging, equipment or business expansion
- 09Available incentives and project economics
The goal is simple: identify a practical system that reduces grid purchases and makes better use of the energy your business generates.
