Two homes on the same street, or two businesses in the same industry, can need completely different solutions.
Who’s home during the day, an EV in the driveway, a pool pump, operating hours, demand charges, roof space, switchboard capacity: it all changes the answer.
That’s why we don’t sell off-the-shelf packages. We design one system for one property, home or business, and explain every part of it.
Why people choose OAKEN
We check it's worth it first.
We start with your bills. If solar and batteries don't stack up for your site, we'll tell you.
We check what others skip.
Your switchboard, backup options and the right battery location, not just your roof.
We only sell what we'd stand behind.
We don't sell every brand, because we couldn't recommend them in good conscience.
You make the decision.
We explain, answer honestly and never push. Then we stand by, before and after install.
Five steps, and every one of them is yours.
No expiring offers. You move to the next step when you're ready.

Send us a recent bill. We look at how much power you use, when, and what you're spending, to see if solar and batteries are a viable option for you.
