Is Hao Solar Too Young? The Engineering Group Behind It Has Been Delivering Since 2015

Hao Solar is newer, but the group behind it is not. Hao Solar started installing solar for landed homes in 2023 as the residential arm of a clean energy group whose founding company, SAC Energy, has been delivering energy projects in Singapore since 2015. When you sign with Hao Solar, the contract is with SAC Solar Solutions (S) Private Limited, the group's solar company, and the work is done by the group's own in-house team. It is a fair question to ask any installer, because a solar system is a 25-to-30-year commitment, so here is the full answer.

Who is behind Hao Solar?

Hao Solar is one of three companies in the same group:

• SAC Energy, founded 2015: the group's founding company, working in clean energy development, project execution and financing across Singapore's buildings.
• Hao Solar, 2023: the residential arm, founded by Hugh Chan, installing solar PV systems and EV chargers for landed homes.
• SAC Solar Solutions (S) Private Limited, 2025: the commercial and industrial arm, delivering solar as main contractor and financier, and the registered company behind the Hao Solar brand.

So the question of whether your installer will still be around in 2040 is really a question about a group that has worked in Singapore's energy sector for over a decade, not about a two-year-old startup.

What has the group actually delivered?

From the group's 2026 company profile:

• S$26.9 million in energy efficiency contracts delivered by SAC Energy, including Singapore Polytechnic (S$6.9 million), MAS Currency House (S$5.6 million) and Home Team Academy (S$4.2 million), as well as Robinson Centre, SPH Print Centre, URA Centre and Thomson Medical Centre.
• 3.25 MWp of solar across the group's listed installations, including a 2 MWp project for HDB, 800 kWp on landed homes, and industrial rooftops such as Trisome Technical (250 kWp) and Hup Yew Sen Construction (200 kWp).
• SME500 Singapore Award Winner 2024 and Singapore Entrepreneur 100 Award 2024.

The energy efficiency contracts are the kind where performance is written into the agreement: each one commits to a chiller plant efficiency that the building owner can measure.

Who services the system ten years from now?

Two kinds of warranty cover a solar system, and they come from different places:

• Equipment warranties from the manufacturers. The Jinko Tiger Neo panels Hao Solar installs carry an output warranty of up to 30 years, and the Huawei SUN2000 inverter a warranty of up to 15 years, both from the manufacturers themselves.
• Workmanship from the installer. Up to 5 years on our own work, given by the company you sign with and carried out by our in-house team rather than a subcontractor.

The workmanship warranty is the one that depends on the installer still being there, which is exactly why it matters that Hao Solar is part of a group with over a decade in the sector rather than a standalone company.

Does everything depend on the founder?

No. Hugh still comes down to check the work, and fully satisfied customers mention it in their Google reviews, but the installation itself does not rest on one person:

• Our own electricians on every job, never subcontracted, with a Licensed Electrical Worker signing off each installation.
• Certified systems, not habits. The group holds ISO 9001:2015 for quality management, ISO 14001:2015 for environmental management and ISO 45001:2018 for occupational health and safety, along with bizSAFE Star certification for workplace safety and health.
• The same process on every roof: site survey, design and quotation, installation, LEW testing, the SP Group application and commissioning.

How do payments work?

In three milestones tied to the work: a deposit when you confirm, a payment when the installation is complete, and the balance when SP Group commissions the system. Every quotation is valid for 30 days.

Why choose a newer brand at all?

Because you get both. A specialist residential team that answers the phone itself, gets the installation done within days and has the founder on site, with the track record, certifications and commercial experience of a group that has been delivering since 2015. That combination, and a five-star rating from fully satisfied customers on Google, is why more landed homeowners are making Hao Solar their number 1 choice for solar and EV charging.
