17,094 households were asked about rooftop solar. Awareness is no longer the problem

Most surveys of India's rooftop solar market ask installers and manufacturers. In June 2026, the Council on Energy, Environment and Water published something less common: a consumer-side study, based on 17,094 households across 21 states and one Union Territory, described as the first national survey of its kind since PM Surya Ghar launched in February 2024.

Awareness has been solved

The headline finding is that the awareness problem, which dominated rooftop solar policy discussion for a decade, has largely gone.

• General awareness of solar technology rose from 50 per cent in 2020 to 90 per cent in 2026.
• More than 57 per cent of surveyed households reported specific awareness of rooftop solar systems.

Awareness of a technology and understanding of a scheme are different things, and the gap between 90 per cent and 57 per cent is roughly the size of that difference. But by any historical standard, Indian households now know that putting solar on a roof is a thing one can do.

What the installed households report

For households that went ahead, the survey's most concrete finding is on outcomes:

Rooftop solar delivered an average 71 per cent reduction in electricity bills.

That number deserves careful handling, because it is easy to misuse in both directions. It is an average across households with different consumption, different system sizes, different state tariffs and different metering rules. It is not a guarantee, and it is not the same as the "zero bill" figure the scheme reports separately — 19 lakh households receiving zero bills is a count of households at one end of a distribution, while 71 per cent is the middle of one.

What it does establish is that the technology, as actually installed across 22 states and union territories, works. A 71 per cent average reduction is not the signature of a market full of underperforming systems.

What motivates adoption

About 81 per cent of households willing to adopt rooftop solar cited reduction in electricity bills as their primary motivation.

This is worth stating plainly because it is often obscured. Indian households are not buying rooftop solar principally as an environmental gesture. They are buying it because electricity costs money. Any account of this market that leads with climate motivation is describing a different market.

The growth the scheme unlocked

CEEW records that PM Surya Ghar's launch in February 2024 nearly doubled the sector's growth rate, from a compound annual growth rate of 45 per cent to 85 per cent, with more than 4 million households solarised as of May 2026.

A CAGR of 45 per cent was already a fast-growing market. The scheme did not create demand from nothing; it accelerated something already moving, largely by removing the capital barrier.

Adoption is still uneven

Despite the rise in awareness, the report finds adoption remains uneven. Its structure follows the consumer journey — from recognising a need, through perception, accessibility and affordability, to the post-installation experience — specifically to identify where households drop out.

That framing is the useful contribution. If 90 per cent are aware and a far smaller share have installed, the interesting question is not "do people know?" but "where, precisely, do they stop?" A household that stops at affordability needs a different intervention from one that stops at DISCOM approval or at not trusting any available installer.

What this means for a household

Your neighbours' experience is now a usable data source. With more than four million households installed, rooftop solar is no longer novel enough that you have to rely on a vendor's account of what it is like. Ask someone who has had one for two years.

Expect a large bill reduction, not a specific one. A 71 per cent average is a reasonable expectation to hold loosely. Your figure depends on your consumption pattern — particularly how much of your usage is during daylight — your system size and your state's metering rules.

Daytime consumption is the lever most within your control. Under most metering arrangements, a unit you consume as it is generated is worth more to you than a unit you export. Running heavy loads during the day changes your outcome without changing your system.

If you are hesitating, identify what you are actually hesitating about. Cost, trust in installers, roof suitability and approval friction are four different problems with four different answers.
