Moving from kW to kWh: Rooftop Solar PV Asset Strategies
26th August 2020 @ 3:00 pm - 4:30 pm IST
While there is much enthusiasm and excitement about India’s thrust towards renewable and especially solar, there are also some concerns about the quality and maintenance of the installations in the rooftop solar segment. Despite the relatively lesser maintenance requirements of rooftop solar PV systems, upkeep of the systems tend to be often overlooked, which can be detrimental to optimal utilization of the assets.
Under the National Solar Mission, the Government of India has set a target of installing 40 GW capacity of rooftop solar photovoltaic by 2022. The official statistics of the Ministry of New and Renewable Energy (MNRE) show that the currently installed capacity is around 2,817 MW as of 30.06.2020 while current efforts are being directed towards substantially increasing the rooftop solar capacity addition with the aim of meeting the target of 40 GW, it is imperative to ensure that these rooftop solar systems perform optimally – with high specific yields (kWh/kWp). The current approach towards this goal has been to increase the installed capacity (kWp) of rooftop PV systems across various sectors. Additionally, the government subsidies for rooftop PV plants are dispersed based on the capacity installed and not the generation achieved from the installed PV plants.
Understanding the importance of ensuring that these installed rooftop solar systems perform optimally, GIZ undertook a technical study titled ‘Moving from kW to kWh’. The study was aimed at currently installed rooftop PV systems to identify the causes of sub-optimal performance, quantify those in terms of contribution to loss in generation and propose cost- optimal solutions to fix the quality issues.The study involved the on-site analysis of the selected rooftop PV plants along with analysis of the contracts, warranties and O&M practices in four locations in India and covered 40 sites from various segments including government, educational, residential and commercial PV plants. The results from the study have highlighted significant shortcomings in installation and maintenance practices for rooftop PV systems with issues such as mechanical damages in cells, soiling and improper plant design and construction among other things which were present in a significant number of plants. Moving forward, it will be imperative that all issues identified in the study are properly looked into to ensure the longevity and further uptake of rooftop solar in India.
In this webinar the key highlights of the study will be presented by GIZ and PI Berlin followed by Panel discussion on the innovating the O&M aspects of solar rooftop power plants.This webinar meets at the intersection of asset owners, managers, investors, IPPs, Discom’s and O&M service providers to create a unique convergence of opportunities to network, learn and share knowledge, representing industry views across the entire asset management and O&M spectrum.
