Zero Investment Solar (OPEX/RESCO)

A RESCO (Renewable Energy Service Company) is a business model where the service provider installs, operates, and maintains renewable energy systems (such as solar, wind, or hybrid) for customers without requiring an upfront investment. Instead, customers enter into long-term power purchase agreements (PPAs), where they pay for the energy they consume at a pre-agreed tariff, typically lower than the grid cost.

Clean Energy Without the Upfront Costs

A renewable energy provider offers clean energy solutions such as solar, wind, or hybrid systems through performance-based models. Instead of selling energy equipment outright, these companies install, operate, and maintain renewable systems at customer sites or via open access, delivering power at a pre-agreed tariff.


This approach eliminates the need for upfront capital investment while giving customers access to reliable, green energy. These service-based companies simplify the transition to clean power for homes, businesses, and industries alike.

Benefits of Partnering with a Renewable Energy Provider

Partnering with a renewable energy provider helps organizations achieve sustainability goals without technical or financial hurdles. Long-term power agreements ensure price predictability and immediate savings on electricity bills.


The provider handles everything from installation and system monitoring to regulatory compliance and maintenance. With growing energy demands and environmental challenges, such partnerships offer a smart, future-proof way to adopt clean energy solutions.

Distributed Solar Solutions

Our Distributed solar energy solutions are in a pay-as-you-go model, by which corporates pay for solar electricity at a rate lower than grid tariffs – in fact, up to 20-40% cheaper.

There is zero investment, no capex and the user does not take on any of the performance risk of the plant. This translates into considerable savings for companies, without the risk. Our team will take care of the entire operation and maintenance for the 25-year life of the system. All you need to do is sign a Power Purchase Agreement (PPA) and sit back and enjoy the benefits.

Renewable Farms (Open Access)

In 2015, we extended this OPEX model to our private solar farms business. Today we have a large network of private farms across major states in India that allow Open Access power procurement, through which we supply large corporates with clean energy. Apart from solar farms, CleanMax has also developed wind farms as well as wind-solar hybrid farms across different states in India which allow Open Access power procurement.

Our renewable farms have different power procurement models from zero upfront investment (under OPEX model), to minimum investment (under Group Captive model) and up to 100% ownership model (as a Captive unit). Additionally, over and above the energy saving model you can also get tax and financial benefits depending on type of power procurement model.

Our innovative solutions enable companies to meet their RE100 aspirations with significant cost-savings as the power is 20-40% cheaper than the grid power.
