Frequently Asked Questions
What is the significance of the DBT scheme, and who administers it?
The DBT scheme, or Direct Benefit Transfer scheme, initiated by the Indian government, aims to lower solar panel prices in Delhi and promote off-season adoption of solar energy. The designated platform for facilitating online processing and disbursement of the scheme is the National Portal for Rooftop Solar.
How does the DBT scheme operate?
Under the government-sanctioned DBT scheme in India, consumers pay the full installation cost to their solar system vendor. Following thorough verification, the scheme refunds the appropriate subsidy amount directly to their bank account. This process is applicable for 30 days after the system is commissioned.
What is virtual net metering, and why is it noteworthy?
Many states are implementing VNEM, or virtual net metering, policies. These policies benefit residential customers by enabling them to receive net metering concessions even if the solar panels are not installed on their property. An example of this type of net metering is community solar farm-based policies, where subscribers of one solar farm receive net metering credits during periods of low power generation. All members equally benefit from this arrangement.
Can I avail solar subsidy in Delhi for any type of solar system?
Solar panel systems are available in various types and sizes to meet the diverse needs of residential and commercial customers. These include off-grid solar, on-grid, and hybrid solar systems. Presently, the solar subsidy in Delhi is only applicable to on-grid solar systems installed on-site.
Would residents of Delhi opt for solar panel installation? Why is the state government emphasizing this initiative in Delhi?
Delhi grapples with poor air quality and high pollution levels. With the government incentivizing the use of solar panels to power residential, commercial properties, and farmhouses, an increasing number of customers are transitioning to solar energy. Modern solar systems have the capacity to generate ample electricity to fulfill our power requirements and offset the usage of grid-supplied power. Unlike conventional energy sources, solar energy generation is clean and does not emit harmful gases into the environment.
