This study shows the results of a pioneer analysis conducted by PI Photovoltaik-Institut Berlin AG (PI Berlin), on behalf of Physikalisch-Technische Bundesanstalt (PTB), of the status of operating grid-connected solar photovoltaic plants installed across India in recent years.

Six representative plants were selected and inspected by PI Berlin between the 3rd and 14th July 2017 thanks to the support of the Solar Energy Corporation of India (SECI) and the Kreditanstalt für Wiederaufbau (KfW), in cooperation with the Ministry for New and Renewable Energy (MNRE) and the National Institute for Solar Energy of India (NISE). The shortlisted plants were selected considering Indian specific environmental stress factors present in different climates, representative module, and mounting structure technologies used in Indian solar plants, and statewide accumulated solar capacity. The selected plants were evaluated by PI Berlin using a Technical Due Diligence product (Q3) developed for operating assets that focuses on aspects such as contracting, installation quality, long term durability of the components, design assumptions, operation and maintenance, PV plant commissioning and system performance calculations.

The purpose of this study is to document the status quo of the six plants in terms of safety, performance, and commercial touching points, and to identify failures, risks and mitigation measures that help to increase the awareness of solar project developers(SPD)and financing institutions in regards to quality assurance of solar PV projects.
