About Cleantech Solar

Cleantech Solar is a pan-Asia solar energy company headquartered in Singapore that has established a strong reputation as a developer and operator of commercial and industrial solar projects across Singapore and the broader region. With 156 Google reviews at 4.9 stars, Cleantech Solar specialises in structured solar financing โ€” primarily through long-term PPAs โ€” that allows industrial and commercial clients to deploy solar with zero upfront capital and immediate cost savings. Their Singapore portfolio includes installations on logistics facilities, manufacturing plants, cold storage warehouses, and data centre campuses. Cleantech Solar's differentiation lies in their ability to structure and finance large projects on behalf of clients who do not want to hold solar assets on their balance sheet. By acting as the project developer, asset owner, and long-term operator, Cleantech removes the operational complexity of solar ownership from the client's responsibilities entirely. Their operations and maintenance teams monitor system performance remotely and dispatch technicians for cleaning, inspection, and fault resolution as part of the PPA service, ensuring that the client receives the contracted energy yield throughout the agreement term. For commercial and industrial clients in Singapore with rooftop areas greater than 1,000 square metres and electricity bills above SGD 20,000 per month, Cleantech Solar's zero-capex PPA model is among the most financially attractive options in the market. Their experience structuring projects that meet the requirements of Singapore's ECIS for grid connection, combined with their track record across over 700 MW of projects in Asia, makes them one of the most credible C&I solar developers operating in Singapore today.
