What we believe
Residential solar isn't a solar business.
It's a consumer business.
Utility-scale solar is project finance. We're the opposite: thousands of families, each making a S$15,000 decision about their own roof, their own bill, their own home.
That puts us closer to Sunrun, Grab and Apple than to a traditional contractor. What matters isn't megawatts — it's trust, install quality, referrals, and how a customer feels five years later.
Singapore has roughly 70,000 viable landed rooftops, and fewer than one in ten have gone solar — a S$1 billion+ market still waiting to be built. We're here to close that gap, and to do it properly.
Our story
From powering 50,000 people across Asia to your rooftop in Singapore.
Before Sunollo, our founders built and ran Mandalay Yoma Energy — the ENGIE joint venture that brought reliable electricity to 50,000 people and 100+ companies across Asia.
They learned what it takes to deliver energy people can depend on — in markets where reliability was never optional and trust was earned one home at a time.
In 2023 they brought that discipline to Singapore: a premium market that deserved a home-energy company built for the next 25 years, not the next signature.

Where we're going
Singapore first.
Asia next.
Across Asia, billions of people will need new energy infrastructure this century — and the grid built for the last era won't serve them. We're proving the model at home in Singapore: premium, distributed, customer-owned. Then we take it across the region, one rooftop at a time.
