Residential rooftop solar in India – pv magazine India
Founded in 2015, Gurugram-based solar EPC player Corrit Energy and Infra caters to a diverse customer profile ranging from large-scale industries to residences. Director and CEO Mayur Misra talks about the current state of residential rooftop solar power in India and emerging trends.
pv magazine: Why has solar power on residential rooftops not taken off in India?
Mayur Misra: There are a multitude of reasons why residential rooftop solar energy has not taken the path it ideally should have. The first being inconsistent subsidy policies over the years for different states. Second, according to consumers, DISCOM is moving slowly with the net metering process. Third, there is still no smooth financing process for consumers to obtain the necessary funds for the power plant, further discouraging the adoption of solar power as not everyone can afford. an initial cost. Another major reason for the weak growth of the residential sector is the lack of awareness of how these factories operate, the costs involved, the return on investment (ROI), etc. In addition, failure to promote success also hampers growth, especially in Tier 2 and Tier 3 cities.
In metropolitan cities, smaller rooftops or shared rooftops like in residential buildings a challenge? How to overcome this challenge?
The wattage capacity of the modules has improved significantly over the years. While 375Wp was the largest module capacity until 2019, we can currently get 550Wp modules on the market.
EPC companies with advanced engineering and design team can design elevated structure to solve shadow problems. These structures also create an opportunity for owners to use the area below. In the future, the modules will also be highlighted in the facade of the buildings.
What has been the trend in component selection for residential rooftop solar power?
Homeowners now favor monocrystalline modules for better generation and efficiency. They’re willing to spend 5-10% more on a better generation, which wasn’t very common two years ago.
Technology has advanced considerably over the past two years. Modules with a power as high as 550 Wp are currently available in the market and people prefer them since they need less space for installation. In addition, there has been a wave of inverter brands entering the domestic market. Brands like Sungrow, Hitachi and Polycab have grown in popularity over the past two years, while Delta and ABB continue to have a good market share.
The Solar plus battery is a must-have solution for consumers facing numerous power outages. This guarantees a back-up battery in the event of power failure in the network. This mode is increasingly adopted in level 2 and 3 cities, especially by commercial and industrial consumers. However, in such an arrangement, the battery investment will be recurring. So it is better to use lithium ion batteries rather than lead acid batteries because lithium ion batteries have a longer lifespan and are built on better technology.
Solar roofs or solar modules mounted on roofs, how to choose?
Roof mounted solar modules allow the homeowner to use their existing roof. A solar roof is currently an expensive option because it requires more components, but it can be chosen by premium customers who intend to put up a new roof exclusively for installation or who need to invest in an elevated structure for installation.
What financing options are available for residential rooftop solar power?
Solar financing is still a very complicated procedure in India and is not very widely available. With the exception of a few nationalized banks, no other bank has a vertical dedicated to the solar power plant. Often, the country’s private banks neglect the ROI aspect of the plant and assess the asset solely on the basis of the customer’s creditworthiness.
Net metering policies vary from state to state. What are your points of view?
While in Haryana, net metering facilities can be used by residential, commercial and industrial (C&I) consumers, they are only valid for residential consumers in Uttar Pradesh. With net metering, the average return on investment is between three and four years for consumers. Without net metering, it goes to about five years.
As an established EPC company, we believe the government should put in place a central net metering system to govern facilities across the country. It will also help with post-installation analysis and data management for the government.
