60 lakh households or 51.7 lakh rooftops? Both are right
In early October the news said India's rooftop solar scheme had reached 60 lakh households. Our daily counter shows 51.7 lakh rooftops. Both numbers are correct. They count different things.
What happenedThe 60 lakh milestone and the 51.7 lakh rooftop count
On 7 October 2026, Republic World reported that PM Surya Ghar, India's national rooftop solar scheme, had crossed 60 lakh households. That is about 60 per cent of the scheme's target of one crore homes. pv magazine India carried the ministry's update the next day.
Both reports also carried a second, smaller number: 50,99,781 rooftop solar systems installed, with 17,855.3 MW of capacity. Neither article explains why the household figure is about 9 lakh higher than the system figure.
Our own daily readings of the national portal show where the gap comes from.
What our tracker showsHouseholds per rooftop in Chandigarh and Bathinda
The news figures match our 6 October reading exactly: 50,99,781 rooftops and 17,855.3 MW. The same reading showed 60,53,987 households. Our counter first passed 60 lakh households on the 3 October reading, at 60,04,747.
The portal keeps two separate counts: households, and installations, which we call rooftops. On the 10 October reading India had 61,36,209 households on 51,72,635 rooftops. That is 9,63,574 more households than rooftops, or about 119 households for every 100 rooftops.
The ratio is very uneven across the country. Uttar Pradesh is at about 101 households per 100 rooftops and Kerala about 102, so there almost every rooftop is one home. Gujarat is about 141, Maharashtra about 154 and West Bengal about 249.
Closer to us, Punjab has 22,577 households on 20,628 rooftops, about 109 per 100. Almost all of that gap sits in one district. Bathinda has 3,917 households on 2,236 rooftops, about 175 per 100, and holds 1,681 of Punjab's 1,949 extra households. Bathinda's household count is even higher than its 2,922 applications, which fits single applications that each cover many households. Bathinda's gap was exactly the same on our first reading on 29 August, so it is not new.
Chandigarh changed in a single reading. Up to the 5 October reading it had 1,676 households on 1,676 rooftops, one for one. The 6 October reading added 2,400 households but only 24 rooftops and about 135 kW of capacity. By 10 October it stood at 4,121 households on 1,745 rooftops, more than 2 households for every rooftop.
National portal, 10 Oct 2026 reading. India is the benchmark. 100 would mean one household per rooftop. India: 61,36,209 households on 51,72,635 rooftops. Chandigarh: 4,121 on 1,745. Bathinda: 3,917 on 2,236. Punjab: 22,577 on 20,628.

What it could mean for IndiaPM Surya Ghar households vs installations
The most likely explanation is shared roofs. One system on a housing society, a group housing block or a building with several families can be linked to many households, so the household count can rise faster than the rooftop count. The portal does not label this, and neither news report explains the gap, so read it as likely, not proven.
Chandigarh shows why care is needed. The 2,400 households added on 6 October came with only about 135 kW of new capacity, roughly 56 watts per household. That could point to shared systems serving common areas rather than a full system for each flat. A household on the counter may not always mean a home that now runs on its own solar.
This could change how India reads progress. The scheme's goal is written in households, one crore of them. If more new households come through shared roofs, the household count may climb faster than the rooftop count and the two could drift further apart. So far that has not happened: the ratio was 119 on 29 August and 119 on 10 October. Both numbers are useful. Rooftops tell you how many systems were built and need service for years. Households tell you how many families are linked to one.
It may also shape who buys rooftop solar next. Many city families live in flats, and a flat owner rarely controls the roof. If society roofs keep growing, a real share of urban demand may be decided by a committee, not a single family, with different timelines and paperwork. Distribution companies could see fewer but larger connections in cities, each serving many homes.
What it means for youHousing society rooftop solar under PM Surya Ghar
If you are an installer or dealer: society and group housing roofs are a real segment, not only independent houses. They are a different sale. Expect a committee decision, questions about which meter the system feeds, structure checks on a bigger roof and a longer timeline. One such job can show up as many households on the portal.
If you live in a flat: you may not need a roof of your own to be part of a rooftop system. Ask your society or residents' association whether a shared system has been discussed, and what it would power, such as common lights, lifts or water pumps.
If you quote numbers: say which one you mean. Households and rooftops are both correct, and mixing them up creates a 9 lakh difference. Our tracker shows both, for every state and district, updated every day.
