Frequently Asked Questions

Common Questions About Commercial Solar in NSW

Straight answers on cost, sizing, payback, and what to expect from a PSC Energy install.

How much does a commercial solar system cost in NSW?

Typically $1,050–$1,300/kW installed after STCs. A 100 kW system usually lands between $105,000 and $130,000 depending on roof type, switchboard configuration, and network requirements. Larger systems (150 kW+) can see better per-kW pricing due to economies of scale.

What size system does my business need?

It depends on your annual kWh consumption and available roof or ground space. PSC Energy designs systems to offset the maximum daytime load — we start with your electricity bills and work backwards to the right system size. A site assessment gives us the full picture including switchboard capacity and network export limits.

How long does commercial solar take to pay back?

3–5.5 years for well-designed 100 kW+ systems in NSW, with electricity rates at 28–33 c/kWh and improving each year. Battery storage can tighten payback further by reducing demand charges. The ROI calculator above gives a solid indication based on your bill size.

Can I add battery storage later?

Yes. Both SigenStack and SigenStor can be retrofitted to an existing solar install. We design with future battery integration in mind from day one where possible — meaning the inverter sizing and switchboard configuration won't need to be redone when you're ready to add storage.

Do I need council approval for commercial solar in NSW?

Generally no DA is required for solar panels on commercial rooftops in NSW — most installations are considered exempt development under the State Environmental Planning Policy. Some heritage-listed or strata sites may have additional requirements. PSC Energy will flag any approval requirements during the design phase.

What warranties come with a PSC Energy commercial install?

Product warranties vary — typically 12–15 years on panels, 10 years on batteries and inverters. PSC Energy backs all installs with our workmanship warranty on top of manufacturer product warranties. Because we use our own installation team, warranty claims are handled directly by the same people who did the work.
