Cleantech Solar Zero-Capex Rooftop and Open Access Solar

Cleantech Solar is a renewable energy company headquartered in Singapore that finances, constructs, owns and operates solar PV and wind projects for corporate customers in Asia. It serves commercial and industrial users in India, Thailand, Malaysia, Indonesia, Cambodia and the wider ASEAN region.

Customers pay only for the energy generated, without upfront capital expenditure. The company offers rooftop solar on factory and commercial roofs, floating solar, and open access solar and wind delivered from renewable energy parks to multiple corporate offtakers. Recent projects include 10 MWp of floating solar for Cargill in Thailand and anchor open access capacity in RE parks in Tamil Nadu and Maharashtra.

• Rooftop solar: systems on factory and commercial roofs with no upfront cost.
• Floating solar: PV arrays on water bodies at industrial sites, such as for Cargill in Thailand.
• Open access solar and wind: power delivered from renewable energy parks to corporate offtakers.
• Pay-for-energy model: customers pay only for the electricity generated.
• Full ownership and operation: the company finances, builds, owns and operates each asset.
• Multi-country delivery: projects across India, Thailand, Malaysia, Indonesia and Cambodia.

Food processing and beverage plants in Vietnam can install rooftop or floating solar on site without capital spending. Multinational groups with plants in several ASEAN countries can use one developer for renewable supply across sites. Factories with small roofs can source off-site renewable power under a direct purchase scheme.

Corporate customers switch to solar and wind without capital expenditure and pay only for the energy produced. The developer finances, builds, owns and operates the assets, so the customer carries no technical risk. Rooftop, floating and off-site park options let sites with limited roof space still reach higher renewable shares.

Multinational manufacturers in Asia are setting RE100 and science-based targets that extend to their regional plants. Zero-capex power purchase models and off-site renewable supply are growing across ASEAN, and Vietnam's direct power purchase mechanism opens a similar route for industrial users.

Headquartered at 75 High Street, Singapore. Named customers include UNO MINDA, Bosch, Saint-Gobain India, Barry Callebaut, Coca-Cola, Kerry, Lotus's, Cargill, Coats Group and Phnom Penh SEZ. In 2026 it signed with Sona Comstar in Tamil Nadu and Coats Group in Indonesia.
