APEIRON pioneered and introduced the “OPEX Model” which is also known as ‘Energy Sale’ model in Indian solar Industry in 2012. Today we have a network of private farms across India, through which we supply large corporates with clean energy as per their needs.

On-site Solution

Our On-site solar energy solutions are pay-as-you-go model, where corporates pay for solar electricity at a rate lower than grid tariffs – in fact, up to 20-40% cheaper. As there is zero investment, there is no capex and none of the associated performance risks either. This translates into considerable savings for companies, which are also risk-free. 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, and sit back and enjoy the benefits.

Solar Farm (Open Access)

In 2015, we introduced this OPEX model in our private solar farms business. Today we have a large network of private farms in Karnataka and Tamil Nadu, through which we supply large corporates with clean energy as per their needs. This solar farm energy solution has zero upfront investment and, as with all our on-site solar solutions, you will get power at rates which are 20-40% cheaper than prevailing grid electricity tariffs. Additionally, as part of our private solar farm vertical, we also offer captive or group captive models, wherein consumers can own a portion of our solar farms and get maximum benefits from the Open Access model, over and above tax and financial benefits.

Maximizing Solar Power Output

At CleanMax, whichever model you choose, we are committed to deliver maximum solar performance, thanks to our all-purpose remote monitoring system. This collects relevant information from all our solar plants and feeds it to our integrated monitoring and maintenance platform, which allows us to:
