Cleantech Solar (Cleantech), established in 2014, is a leading Pan-Asia regional rooftop solar developer, owner and operator that offers full-service solutions to commercial and industrial (C&I) customers looking to reduce their carbon footprint. A rooftop photovoltaic power system is a system where electricity generating solar panels are mounted on the rooftop of a building (in this case commercial and industrial consumer buildings) and connected directly to the building’s power supply for usage. As this reduces the amount of power drawn from the grid (reduced electricity meter reading), such systems are commonly also known as ‘behind-the-meter’ systems.

E&S Context

The environmental and social risk rating of the portfolio has been classified as Category B (in accordance with CI1’s risk categorization), which is equivalent to International Finance Corporation (IFC) Category B. This is due to the limited potential for adverse social or environmental impacts associated with the activities of the business (rooftop solar installations).
Individual assets may be rated differently; for example, open access solar sites in India are generally rated individually as Category B+. This reflects the potential for adverse environmental and social impacts that extend beyond site boundaries but are largely reversible and can be addressed through relevant mitigation measures.
CI1 continues to conduct assessments of the environmental and social impacts of new projects in development and provides guidance as required. Ongoing monitoring and review of CSA’s environmental and social performance is conducted, and various environmental and social initiatives are being undertaken. These include developing an environmental management system and contributing to research on sustainable disposal of end-of-life solar panels.
