Design, engineering, procurement and installation of rooftop and ground-mounted photovoltaic systems for factories, warehouses and commercial buildings.
Work covers grid-tied inverters, mounting structures and grid connection under the Enhanced Central Intermediary Scheme. Buyers select on EPC track record, financing model and operations-and-maintenance terms. The companies on the record holding this capability are collected on the Singapore Industry Index’s list of Leading solar & renewable energy companies in Singapore.
The buyer of commercial & industrial (C&I) solar in Singapore is a factory, port, logistics operator, mall REIT or government agency, and the questions they ask are unlike a homeowner's: what is your installed MWp track record, will you fund it as solar-as-a-service under a 15–25 year PPA so there is zero upfront capex, can you build floating and ground-mount as well as rooftop, and have you cleared an EMA/SolarNova government tender. This is a tender-led and PPA-led market, not a retail one — the searchable demand ("HDB solar," "residential solar Singapore") points at an audience this capability does not serve, because C&I megawatts are awarded through JTC's SolarLand and HDB/EDB's SolarNova programmes, PUB floating-solar tenders, and bilateral corporate PPAs. Singapore's national target is 1.5 GWp of solar by 2025 rising toward 2 GWp by 2030 (EMA/EDB), and roughly a third of that is being delivered by a single company, so the field is concentrated and evaluated on balance-sheet depth and O&M reliability rather than price alone.
The shape of the industry is a short list of large developers and independent power producers (IPPs) sitting above a longer tail of EPC and O&M contractors. Sembcorp Industries (SGX: U96) crossed 535 MWp of Singapore solar and operates the 60 MWp Tengeh Reservoir floating farm (122,000 panels across 45 hectares) plus the won 86 MWp Pandan Reservoir floating tender — one of the world's largest inland floating clusters. EDP Renewables APAC, which absorbed home-grown Sunseap in 2021, holds the SolarNova 1/4/8 pipeline (~380 MWp) and runs the 9.5 MWp Jurong Port array billed as the world's largest port-based solar facility, and won the largest-ever public tender (up to 200 MWp). Floating and offshore solar (Tengeh, Kranji, the Johor Strait) is the local frontier because land is scarce; manufacturing is not — REC Solar in Tuas is the lone panel maker, turning out roughly 4 million heterojunction (Alpha) modules a year, while Singapore-headquartered Maxeon designs cells but fabricates offshore. Structural shifts to watch are successive SolarNova tranches (now SolarNova 8), PUB's move from Tengeh to Pandan and larger reservoirs, and low-carbon electricity import corridors (Sembcorp's conditional 1 GW from Sarawak) that reframe "clean energy" beyond domestic panels.
Companies with this capability in Singapore
Listed alphabetically. Order does not indicate ranking.
Cleantech Solar finances, builds, owns and operates solar and wind plants for commercial and industrial customers across Asia, holding roughly 1.2 GWp of projects in operation, construction and development across seven countries from India to Vietnam. Customers pay only for the energy generated, with no upfront capital. Headquartered in Singapore, the company became wholly owned by Keppel Ltd. and Keppel-managed investors in November 2025, when Shell sold its 49 per cent stake.
A regional solar independent power producer that absorbed Singapore solar pioneer Sunseap. It holds the SolarNova 1/4/8 pipeline (~380 MWp) and SolarLand Phase 3 (60 MWp), operates the 9.5 MWp Jurong Port rooftop billed as the world's largest port-based array, and won Singapore's largest public solar tender to date (up to 200 MWp). South-East Asia portfolio around 2 GWp.
The South-East Asia arm of the French energy major, spanning distributed solar and demand-side energy services. It has 24.5-plus MWp of solar installed in Singapore and 100-plus MWp across the region, with C&I sites including KK Hospital and Changi Airport and a FairPrice Group multi-site programme. As a NEA-accredited ESCO it offers Utilities-as-a-Service with AI-driven plant optimisation and district cooling, with reference projects at the National University of Singapore and Punggol Digital District. Parent of the SME PPA platform GetSolar.
An ENGIE-backed commercial and SME solar PPA platform offering zero-upfront solar from systems as small as 20 kWp, with over 200 installations.
An SGX-listed asset manager and operator whose infrastructure arm spans three clean-energy capabilities. In solar, Keppel Renewable Energy develops solar and cross-border clean-power, progressing an Indonesia-to-Singapore electricity import licence. In water, Keppel Seghers built and operates the 137,000 m3/day Keppel Marina East Desalination Plant and delivered the 162,800 m3/day Ulu Pandan NEWater upgrade. In waste, it runs the ~2,310 t/day Senoko and ~800 t/day Keppel Seghers Tuas waste-to-energy plants, together treating close to half of Singapore's incinerable waste.
A commercial-and-industrial solar independent power producer and asset owner across six Asian markets, with around 543 MWp operational including some 30 MWp of Singapore C&I rooftop.
A Singapore-headquartered high-efficiency solar cell and panel company (a SunPower spin-off) supplying premium modules; design and headquarters in Singapore, with cell fabrication offshore.
A Singapore-based commercial-and-industrial solar developer and EPCC-plus-O&M contractor operating regionally, targeting carbon-neutral corporate rooftop clients.
Singapore's only solar-panel manufacturer, running an integrated heterojunction (Alpha) module complex in Tuas producing on the order of 4 million panels a year; also executes local rooftop EPC.
A Singapore commercial-and-industrial solar EPC and O&M contractor with a portfolio of commercial and industrial rooftop projects for local factory and warehouse clients.
