One-stop commercial & industrial solar for Singapore businesses: design, installation and O&M. With solid engineering, we turn every rooftop into a sustainable source of profit.
Three reasons Singapore businesses trust us.
Our best project on record reached 1,440 kWh/kWp per year, averaging 1,300 kWh/kWp per year, all measured data.
Well-versed in SCDF fire safety, SP grid connection and BCA/URA approvals: the complete Singapore approval chain, so projects avoid detours and land on time.
For unshaded sites we guarantee at least 1,250 kWh/kWp per year; any shortfall will be compensated in accordance with the contract terms.
40+ C&I solar projects delivered, 30+ MWp of grid-connected capacity, across Singapore's industrial estates, public agencies and commercial buildings.

From rooftop survey to long-term O&M, one team handles it all.
From roof survey and load assessment to grid connection, delivered end to end.
Annual inspection and cleaning to keep systems running at peak efficiency.
Raises system safety and keeps you compliant with fire codes.
Scalable storage to maximise self-consumption of solar power.
Regular inspection and cleaning significantly reduce degradation and extend equipment life.
Real voices from C&I property owners.
From survey to grid connection, the Hey Solar team was professional throughout. Our project went live on time and generation even exceeded expectations.
Transparent pricing and a clear process. SCDF and SP approvals were fully handled by their team, and our payback came in faster than estimated.
The O&M team inspects meticulously. Their inverter and meter reports give us real confidence. Our system has run stably ever since.
Our roof structure was fairly complex. They surveyed three times before settling on the design, and installation never once disrupted daytime production.
Approvals and owner communication on an MCST project are tedious. Hey Solar sorted the process out step by step and it passed the general meeting smoothly.
Generation hit the estimated level in the very first month after grid connection, and we can see the data on the monitoring platform every day.
Under two months from quotation to completion, faster than we expected, and the site was left spotless.
Routine thermal imaging caught two abnormally hot joints and we fixed them in time, avoiding what could have been a costly downtime.
SCDF fire safety approval is the trickiest part. Their submission went through first time and saved us a great deal of time.
Every grid-connected project contributes to a cleaner energy future.
