Built on trust,
powered by People.
From our first install to hundreds of solar-powered homes. We grow by doing things the right way: with quality, integrity, and a genuine pride in our work.
Our Story
We saw a problem — and fixed it.
Going solar shouldn't be complicated. But for too long, homeowners were stuck with confusing quotes, pushy salespeople, and prices that changed on the day.
We started Wattli to change that. Our model is simple: fixed prices, no surprises, and a job done properly — every time. We're solar panel specialists. It's all we do, and we're proud of it.
Every engineer is MCS certified, insured, and part of our team. We don't use subcontractors. When you book with Wattli, you know exactly who's coming, what they're doing, and what it'll cost.
"The complexity was unnecessary. We knew that by putting the customer first and keeping things simple, we could make the entire process fast, fair, and reliable."
— Wattli Founders
