What system size suits my business?

Most commercial sites land between 100 kW and 1 MW. ESQ sizes against 12 months of interval data so the system matches your load — not your roof area.

How are STCs and LGCs handled?

ESQ creates, assigns and trades both certificate classes on your behalf. The value is netted off your installed price up-front.

Will my network operator approve export?

We hold pre-approval pathways with Energex, Ergon, Ausgrid, Endeavour, Essential, Jemena, Powercor, CitiPower, United, SAPN, TasNetworks, Western Power and PowerWater.

What warranty applies?

Tier-1 modules carry a 25-year product and performance warranty. Inverters carry 10 years standard, extendable to 20. ESQ workmanship is warranted for 10 years.
