Commercial solar for Perth businesses, scoped off your bill, not your roof space.

A business bill is not a bigger house bill

On most commercial tariffs you are charged twice. Once for the energy you use, and again for your highest demand in the billing period, measured over a short window. That second charge is set by one moment in the month, and a system designed against your annual consumption can miss it entirely.

So the first thing we ask for is your interval data, which your retailer will give you on request. It shows your load in half hour blocks across a year. Read against your trading hours it tells us when your demand peaks, whether solar lands on that peak or beside it, and whether storage is what actually moves your bill. A walk around the site cannot tell us any of that.

The roof is the last thing we look at

Plenty of commercial solar is scoped the other way round: count the usable roof, fill it, and price it. It produces a system that generates well and a bill that barely moves, because generation was never the constraint.

We work back from the bill. What your load actually does through the day, what your demand charge is set by, what your operating hours are, and what you are planning that will change any of it. The roof then has to accommodate the answer, and where it will not, that is a finding we give you rather than a corner we cut.

One licence across the whole job

SolArk is an electrical contractor that specialised into solar rather than a solar company that later hired an electrician. On a commercial site that distinction stops being philosophical: the switchboard, the mains, the metering, the protection and the network paperwork are most of the job, and they are the parts that hold a project up when they are somebody else's responsibility.

We do the electrical work ourselves, under our own licence, on the same job. There is nobody to hand your site to and nobody to point at.

A commercial customer looking at a battery that did not suit their situation. Their words afterwards: you've talked us out of it.

Battery storage for a business

A commercial battery earns its keep differently to a home one. At home it is mostly about using your own solar after dark. On a business tariff it is usually about the demand charge, and about what a power outage costs you per hour if your operation cannot ride one out.

Both of those are answerable from your data rather than from opinion, which means the honest answer is sometimes no. We have given that answer to a commercial customer who came to us wanting a battery, and their own words afterwards were that we had talked them out of it. If the numbers do not support it, or a smaller change to how the site runs does the same job, we will say so.

Commercial electrical, not only solar

Switchboard and mains upgrades, lighting, fault finding, compliance testing and the reactive calls that cannot wait until next week. We already run ongoing electrical work for a Perth agency across a rotating slate of properties, to a booked window and a flat fee, which is the same discipline a business site needs.

Working around your trading hours

A shutdown is usually the expensive part of a commercial job, not the equipment. Where the site allows it we stage the work so the disruptive steps land outside trading, and where a shutdown is genuinely unavoidable you get the window in writing before we start rather than a phone call on the morning.
