Rooftop solar · Who pays
Rooftop solar always sends a bill to someone. Who is left holding it?
India's total subsidy bill grew 3.7 times in one year. In the US the tax credit ended, and one of its biggest installers collapsed.

First principles
A rooftop system costs a lot on day one and pays you back slowly.
You pay for the panels and the wiring up front. The savings arrive a little each month, for years.
So at the start there is a hole between what the system costs and what a family can pay. Someone has to cover it.
Illustration drawn for this story. No real numbers.
First principles
The hole has to land somewhere. There are only four places.
Public money can fill it. Other electricity customers can fill it through their bills. The buyer can fill it by paying more. Or the firms in the middle can swallow it.
The rest of this story looks for which one is paying.
The story in four numbers
Two countries, two answers to the same question.
What changed this week
Three news items, one question.
The power regulator in Bihar, in eastern India, proposed paying only half the usual rate for extra rooftop power left at year end. It is a draft.
Australia became the first country to back a global plan to double the world's homes with rooftop solar by 2030.
This Friday is the last day for customers of the collapsed US installer Freedom Forever to file claims.

India
India adds rooftop solar three times faster than 15 months ago.
A gigawatt is a billion watts. In the first three months of 2025, India added 1.2 gigawatts of rooftop solar. In the three months to June 2026 it added 3.8.
That is 3.2 times as much. These counts come from a private research firm, not from the government, so read them as a strong guide and not an exact tally.

India · Taxpayers
Who pays in India? Taxpayers. The total grew 3.7 times in a year.
The central government pays part of the cost of each home system. Add up everything paid so far: ₹4,309 crore in January 2025, ₹16,061 crore a year later.
A crore is ten million, so that is about ₹160 billion.
Bihar · The newest news
In Bihar the owner may pay: a draft would halve the rate for extra power.
DraftSome roofs make more power than the house uses. The extra goes to the grid. At year end, the draft would pay for what is left at half of the set price. It would also cap these systems at 500 kilowatts.
Who paysThe households and firms with the most extra power. The electricity company pays less.
ContestedOne report frames year-end buying as a benefit to consumers. We do not know today's rule, or if this is one proposal or two.

United States · The middle
The US credit ended on 31 December. Seven months later, a top installer was gone.
Until the end of 2025, a US buyer got a tax credit worth 30% of the system's cost. A law signed on 4 July 2025 ended it for systems finished after 31 December.

United States
US home solar fell 12% by spring. The forecast for the year is a 23% fall.
FactEarly 2026 was still 6% above a year earlier. By April to June it was 12% below.
Our readAnalysts point to the end of the credit, a big installer failing, and tighter money from lenders. We cannot prove which mattered most.
Source: SEIA / Wood Mackenzie, Solar Market Insight Q3 2026. Q4 2025 is left out because two reports disagree on it.
United States
About 6 of every 100 new US home solar systems came from Freedom Forever.
Picture the whole US home solar market in 2025 as 100 squares. Sunrun held about 13. Freedom Forever held about 6, which made it number two.
Our readWhen one of the top two fails, many homes lose the firm that was meant to finish the job or honour the warranty.
United States · The end of the line
When the money stops, the people at the end of the line wait.
A home solar job passes through hands. The buyer pays a deposit. The installer does the work. If the installer collapses halfway, the buyer can be left with a half-built roof and a warranty from a firm that is gone.
Freedom Forever customers have until 16 October 2026 to file a claim. Filing is not the same as being paid.

Australia · The world plan
The plan to double the world's solar roofs has no named payer yet.
On 8 October Australia became the first country to back a plan to go from about 150 million homes with rooftop solar to 300 million by 2030.
The plan is voluntary and not binding. In the sources we read, it gives no price tag and does not say who pays.
Risks and counter-case
The strongest case against this story.
Buyers still gain.
A subsidy or credit is a transfer, and it buys real panels. India's scheme had put 2.27 million systems on roofs by January 2026.
Fact
US demand may return.
SEIA and Wood Mackenzie expect a recovery after the 2026 fall, and Solar Power World reports growth is forecast again in 2027.
Forecast
It may be one weak firm.
Freedom Forever's fall may say more about its own debts and sales model than about who pays. Bihar's 50% rate could also protect customers who pay for the grid. We have no source for that last point.

What to watch next
Four dates, and one with no date.
The next test of who pays comes in the courts, at the climate talks, and in India's cell rule.

Sources and claims log
What we checked, and what we left off the page.
A claim needs two independent sources or one primary source. Contested: the Bihar framing, and US Q4 2025 installs. Not found: the current Bihar rule, a count of US installer failures, and any price tag for the global plan.
