PM Surya Ghar Yojana has helped more Indian homes explore rooftop solar. After the installation of more than 40 lakh systems, the government is preparing for the next phase, known as PM Surya Ghar 2.0. The second phase may focus on battery storage, long-term service, shared solar systems and simpler access to finance.
The first phase began on 13 February 2024 with a budget of Rs 75,021 crore. Its main target is to support rooftop solar for 1 crore homes by March 2027. The new phase is still linked to proposed changes, so users should wait for official rules before booking a system based on these features.
Long-term service may become a key rule
Solar panels can work for many years, but the inverter, wiring and other parts may need checks or repairs. A common problem is that a small solar vendor may close down after a few years. In that case, the customer may struggle to find support for the system.
PM Surya Ghar 2.0 may ask approved vendors to provide service for a longer period. The plan could include clear service duties, response timelines and support for the full working life of key equipment.
This change can give buyers more confidence. A rooftop solar system is not like a phone that you replace after two years. It sits on the roof and faces heat, rain, dust and the occasional overexcited pigeon.
Solar benefits for people without a private roof
Many families live in flats, rented homes or housing societies. They may want to use solar power but do not have a separate roof for installing panels. PM Surya Ghar 2.0 may address this issue through group metering and virtual net metering.
Under a group solar model, several homes may share one solar plant. The power produced by the plant can be divided among the participating homes. This could help residents of apartment buildings, housing societies and shared properties use solar power without installing a separate system on every home.
Virtual net metering may allow the credit from a solar plant to be adjusted against the electricity use of different connections. The exact process will depend on rules set by the government and state electricity regulators.
Battery storage may enter the subsidy plan
The first phase kept battery storage outside the main subsidy structure to control costs. The second phase may bring storage systems into the scheme. This is important because solar panels produce power during the day, while many homes use more electricity in the evening.
A battery can store extra solar power and supply it later. It can also provide limited backup during power cuts, based on its size and the home’s load. A battery will not run every appliance for an unlimited time. Heavy devices such as air conditioners, water heaters and pumps can use stored power very fast.
The government is studying different locations for storage. Batteries may be installed:
- Inside individual homes
- Near local transformers
- At the level of electricity distribution companies
Each model has a different cost and use. Home batteries can offer direct backup. Transformer-level storage can support a group of users. Utility-scale batteries may help manage supply across a larger area.
Digital monitoring may improve transparency
The next phase may use digital monitoring for solar systems. A monitoring platform could track installation status, power generation, equipment performance and maintenance requests.
This can make it easier for customers to see whether their system is working as expected. It may also help officials check whether approved vendors complete installations and meet service standards. A digital record could reduce delays in subsidy processing, though the final process will depend on official guidelines.
Better equipment and simpler loans
Equipment quality may receive more attention under PM Surya Ghar 2.0. The quality of panels, inverters, batteries and safety devices affects output, system life and repair costs. Buyers should check the product warranty, installation terms and after-sales support before signing any order.
Easy bank loans are another expected focus. Solar systems need a large upfront payment, even after subsidy support. A simple loan process can help more families spread the cost over monthly payments. Borrowers should compare the interest rate, processing fee, repayment period and conditions before accepting a loan.
What users should check before installing solar
- Confirm the vendor’s approval status on the official scheme portal.
- Read the panel, inverter and battery warranty terms.
- Ask who will handle repairs if the vendor stops operating.
- Check the roof condition, shade and available installation space.
- Ask the electricity provider about net metering rules in your area.
- Do not treat a proposed subsidy as confirmed until the government publishes the final notification.
For apartment residents, the housing society may need to approve a shared solar system. The society should also decide how it will divide generation, maintenance costs and electricity credits among members. Applicants should keep invoices, installation records, warranty papers and subsidy details for future service requests.
