If you are thinking about installing solar power at home, the government's next phase of rooftop-solar expansion could make battery storage an increasingly important part of the system.

The government is already pushing rooftop solar through the PM Surya Ghar scheme, while industry discussions around its next phase are focusing on combining rooftop solar with batteries.

Why Are Batteries Becoming Important?

A rooftop solar system generates electricity mainly during daylight hours. However, most households also consume electricity in the evening and at night.

A battery can store excess solar power generated during the day and make it available later.

This could help households use more of their own solar electricity instead of depending entirely on grid power after sunset.

Government's Solar Push Is Getting Bigger

The government has approved the Pradhan Mantri Surya Sarovar Yojana, which aims to support 5,000 MW of floating solar photovoltaic projects along with energy-storage systems. The approved plan includes storage capacity of at least two hours, totalling 10,000 MWh.

While this is focused on larger solar projects rather than directly giving every household a battery, it reflects the government's broader push toward combining renewable energy with storage.

What Could This Mean for Homeowners?

For households considering rooftop solar, battery storage could provide several advantages:

• Better use of electricity generated during the day
• Greater energy availability after sunset
• Reduced dependence on grid electricity
• Potentially better protection against certain power interruptions
• Greater use of renewable energy within the home

However, batteries also increase the initial cost of a solar installation. Therefore, homeowners should compare the additional battery cost with their actual electricity consumption before purchasing one.

PM Surya Ghar Scheme Is Still Available

The official PM Surya Ghar portal currently shows that the scheme is scheduled to remain open until March 31, 2027.

If you are considering rooftop solar, you should check the current subsidy eligibility, approved vendors and installation requirements through the official portal rather than relying on advertisements or social-media claims.

Should You Install a Battery With Solar?

Not necessarily.

If your household consumes most of its electricity during the daytime, a basic rooftop solar system may already provide substantial value.

A battery becomes more relevant if:

• Your electricity consumption is high after sunset
• You want greater energy independence
• Your area experiences frequent power interruptions
• You want to maximise your use of self-generated solar electricity

The right setup ultimately depends on your household's electricity consumption, roof size, local solar conditions and electricity tariff.

What Consumers Should Check Before Installing Solar

Before paying an installer, check:

1. Whether the vendor is eligible under the applicable government scheme.
2. The current subsidy rules and eligibility conditions.
3. The expected monthly electricity generation.
4. Whether battery storage is actually necessary for your usage.
5. Warranty terms for the panels, inverter and battery.
6. Installation and maintenance costs.
7. Whether the system can be expanded later.

The Bottom Line

India's solar push is increasingly moving beyond simply installing solar panels. Energy storage is becoming an important part of the conversation as the country adds more renewable capacity.

For households, this could eventually mean more flexible solar systems that can store daytime electricity and use it when needed. But before investing in a battery, consumers should calculate whether the additional upfront cost makes financial sense for their individual electricity usage.
