Commercial Solar in Darwin.
Businesses that run through the day are the best possible fit for solar — you consume what you generate, at the moment you generate it. Offices, workshops, retail and light industrial across Darwin and Palmerston.
Common sites
Sized Against the Load Profile, Not the Roof
The temptation with commercial solar is to fill the roof. On a business tariff that is often the wrong answer — the value is in offsetting consumption at the times you actually consume, and demand charges do not care about your solar at all unless the system is designed with them in mind.
We work from interval data where it is available. That tells us what your load actually does through the day, which is what should decide system size rather than how much roof happens to be there.
Where Commercial Differs
Three things that change on a business site.
Tariffs Are More Complicated
Demand charges, time-of-use rates and capacity charges mean the saving is not simply consumption multiplied by a rate. Modelling it properly changes the sizing.
Downtime Has a Cost
Switchboard work and connection on a trading site has to be scheduled around operations. That is part of the job, not an inconvenience to be sprung on you.
Roofs Vary Enormously
Commercial roofs range from ideal to unusable — age, sheeting type, structural capacity and existing plant all affect what can go up there. Worth assessing before designing.

Solar, Electrical and Air Con on One Site
Commercial premises rarely need solar alone. Switchboards, lighting, power and air conditioning maintenance usually come with it. Flynn’s holds electrical and refrigeration licences and does solar, so one contractor can handle the site rather than you coordinating three and refereeing between them.
Great communication, great work, fair prices. They told us they do domestic electrical work so we’ll definitely be contacting them for future works. Highly recommended.— Alexander G.
After extensive research and a number of quotes from different installers, these guys stood out. They were the most thorough when it came to preparing a quote, asking lots of questions and doing a detailed inspection of our property. I was left with no doubt about which system best suited our needs and why. If you want a genuine team of experts who take a measured and detailed approach to both system specification and installation, I can’t recommend Shane Frew and the rest of the Flynn’s Team enough.— Sandra Y.
Friendly, professional and excellent service. Will recommend to anyone, and will use again!— Kerry B.
Frequently asked questions.
What commercial clients ask.
Is commercial solar worth it in Darwin?
For a business consuming power through the day, generally yes — you use what you generate at the moment you generate it, which is the best case for solar. The detail depends on your tariff and load profile, which is why we start with bills and interval data rather than a roof measurement.
How do you size a commercial system?
From your actual consumption through the day, not from available roof space. On commercial tariffs, filling the roof is often the wrong answer because export earns far less than the consumption it offsets.
What about demand charges?
They need to be modelled specifically, because solar alone may do very little to them depending on when your demand peak occurs. Sometimes storage addresses it, sometimes it does not. We will be straight about which.
Will installation disrupt trading?
We schedule switchboard work and connection around your operations. For retail and hospitality that usually means out of hours. It is planned in from the start rather than sprung on you.
Can you assess multiple sites?
Yes. We assess the portfolio, prioritise by return and report on the lot, so you can stage the investment rather than deciding site by site in isolation.
Do you handle the grid connection application?
Yes. Commercial connections can be more involved than residential, particularly for larger systems, and we manage that process.
