Top 10 Zero CapEx Solar Companies in Singapore

Looking to install solar panels without the hefty upfront investment?

Thanks to zero CapEx solar solutions, it’s easier than ever to power your home or business with solar in Singapore.

This model removes the need for large capital expenditure, making solar energy more accessible to businesses and homeowners alike. With energy costs rising and sustainability becoming a priority, more companies are offering zero CapEx options that let you save from day one.

What is Zero CapEx Solar?

“Zero CapEx” stands for zero capital expenditure. In simple terms, it means you don't pay anything upfront for your solar installation. Instead, the solar provider handles the design, installation, and maintenance of the system. Depending on your agreement, you then either:

• Pay a discounted rate for the electricity (Power Purchase Agreement or PPA), or
• Pay a fixed monthly fee under a Rent-to-Own model, eventually gaining full system ownership, or
• Earn monthly rental income by leasing your roof to a solar provider.

Why More Businesses Are Going Zero CapEx

Here's why zero CapEx solar energy solutions are growing in popularity in Singapore:

• No Upfront Investment – Remove financial barriers to adopting solar energy
• Immediate Electricity Bill Savings – Reduce energy costs from the first month of operation
• Lower Carbon Footprint – Support ESG and decarbonisation goals
• Long-Term Advantage – Gain energy independence and cost stability
• Minimal Risk – Maintenance, insurance and system performance are often covered

Common Zero CapEx Solar Models in Singapore

Traditionally, zero CapEx solar projects in Singapore were offered primarily through Power Purchase Agreements (PPAs) — where customers purchase solar electricity at a discounted rate compared to the standard utility tariff.

Today, new models such as Rent-to-Own (RTO) and roof rental have emerged.

• Rent-to-Own (RTO)  – Pay fixed monthly instalments and take full ownership at the end of the term
• Roof Rental – Lease your rooftop to solar developers and earn passive income while they operate the solar system

These options offer greater flexibility, allowing customers to choose between long-term discounted energy, eventual system ownership, or leasing out unused roof space for passive income.
