The South Delhi Municipal Corporation (SDMC) has eased the norms related to the height of the panels. There was earlier a two-metre height regulation in Delhi, which has now been removed. The new rules allow rooftop panels at any height or levelsubject to the maximum height permitted by Airports Authority of India and clearance from Delhi Fire Services. The bylaws have been amended and notified by Delhi Development Authority. This is expected to make it easier for installing more rooftop solar systems in the city. However, for higher installations, more advanced and expensive mounting structures may be required along with a more robust base construction to ensure durability. Rooftop projects are technically more complex as each plant has to be customised according to the roof size and demand load. Further, in the rooftop engineering, procurement and construction, and product markets, a variety of players are offering products and services of varying quality.
The government has set a target to install 100 GW of solar power capacity by 2022, of which 40 GW is to be achieved by the rooftop solar segment. Several policy measures have been announced across India for the large-scale deployment of solar rooftop projects. These include comprehensive rooftop solar policies and net metering regulations, along with streamlined utility interconnection processes, which have led to rapid deployments in the rooftop solar space.
