What are the advantages of PM’s rooftop solar plan and who may utilize it?

On February 13, the “PM-Surya Ghar: Muft Bijli Yojana” was introduced, with a 75,000-Cr fund. Encouraging one million homes to install rooftop solar panels and support environmental objectives
What advantages will users have?
Depending on the size of the rooftop capacity and usage, installing rooftop solar panels would provide a home with a monthly supply of up to 300 units of free electricity and an anticipated yearly savings of Rs 15,000–Rs 18,000.

Installing charge stations for electric vehicles, particularly automobiles and two-wheelers, may also provide income for households, particularly in rural regions.
Who may submit an application? Furthermore, how?
Although the subsidy is only offered for rooftop systems with a capacity of up to 3 kW (3,000 watts), any home may apply. Applications are accepted at https://pmsuryaghar.gov.in; the website also provides assistance in determining the rooftop system’s suitable capacity and advantages.
Exist any prerequisites?
For households to be eligible for subsidies, they must install a solar energy system using ‘Made in India’ solar panels and a vendor that has been approved by the government (listed on the webpage). In order to get a subsidy, a home cannot have battery storage.
What is covered by the subsidy?
Assistance with financing is only available for systems with a maximum capacity of 3 kW. 60% of the cost of a system up to 2 kW in capacity and 40% of the extra cost for systems between 2 and 3 kW in capacity are covered by the subsidy. This equates to a subsidy of around Rs 30,000 for 1kW systems, Rs 60,000 for 2kW systems, and Rs 78,000 for systems with a capacity of 3kW or more. The subsidy will be sent straight into the beneficiary’s bank account after the installation of rooftop solar panels and the completion of government authorities’ due diligence.
Does the user need to make any payments?
The remainder due after the subsidy is applied, which is at least 40% of the total cost, must be paid for up front by households. There are hints that, should economically disadvantaged households living in smaller homes—particularly those constructed under the PM Awas Yojana—not be able to afford the initial outlay, central electricity providers may be called upon to install rooftop systems. In these situations, the electricity PSU will get the subsidy and be responsible for the initial outlay. To finance the first investment, households may also take advantage of loans with favorable interest rates.

What makes the new scheme unique?
Compared to Phase-II of the residential rooftop solar program, which was introduced in March 2019, the new plan gives a larger subsidy. Subsidy applications that are received before February 13 will still get government assistance under the previous program.
How much does a rooftop system cost?
The cost of a rooftop system is determined by the quantity, size, efficiency, and specifications of the solar panels. The cost is also influenced by the peripheral electronics and mounting quality. Upwards of Rs 72,000 may be spent on a 1 kW rooftop system, and above Rs 1.6 lakh on a 3 kW unit.
Which solar panels should I use?
Panels with mono or bi-face features are available. Either way, the quantity of sunlight turned into energy is indicated by the efficiency rating, which also establishes the overall energy output. After 25 years, the panels continue to generate electricity, but at a reduced capacity.
How many panels are required?
The majority of 1 kW systems consist of three or four 250–330 watt solar panels. The number of panels required to provide the rated power output is reduced by high-efficiency panels. As the capacity grows, so does the number of panels.
How is the production of electricity calculated?
Through the use of net metering, which turns customers into “prosumers,” homes with rooftop solar systems are able to sell their excess energy to the utility grid.
How is net metering implemented?
The family uses a conventional connection to draw electricity from the grid when solar power output is insufficient to meet demand, and the customer is billed for the quantity of units utilized. When solar power output exceeds the amount of energy required, the excess enters the distribution system via the grid connection. At the conclusion of the billing cycle, a home is either charged for the amount of power consumed or paid for the number of units sent into the main line, depending on whether it has used more than it has provided or is a net contributor to the grid. It is also possible to carry over the positive amount to the subsequent billing cycle.
