About
The purpose of this study is to identify the causes of underperformance in rooftop plants in India
and suggest economically viable mitigation measures.
More
Sites
A total of 100 sites located in several areas of India have been inspected in the framework of this
study. Mainly plants with low yields were selected.
More
Findings
11 main findings have been identified as responsible for the underperformance detected in the
plants. Some of them are especially relevant as they are present in all inspected sites.
More
Outlook
Lenders, planers, installers and owners can benefit from the conclusions obtained from this study
in order to minimize risks and ensure the revenues for the next generation projects.
