For most of the last decade, the story of solar was a happy one: prices fell, year after year, until panels became one of the cheapest sources of electricity on Earth. In 2026, that script is being rewritten — not in a factory, but on a 33-kilometre stretch of water near Iran.

The conflict in the Gulf and the near-shutdown of the Strait of Hormuz have triggered what energy agencies are calling one of the largest oil-supply disruptions in modern history. Brent crude jumped sharply, freight rates climbed, and the shockwaves did not stop at the petrol pump.

Solar may run on sunshine, but it is built from metals and shipped across oceans. Two of its key ingredients — silver, used inside the cells, and aluminium, used in the frames — turned highly volatile this year as investors and inflation reacted to the war. Add the surge in shipping and freight costs, and the bill for a finished module starts to swell.

The result, according to leading Indian manufacturers, is a 15–20% rise in solar module prices through early 2026 — driven mainly by costlier freight and volatile input materials rather than any shortage of panels themselves.

There is a second, slower-moving force in play. From 1 April 2026, China — which makes roughly 80% of the world’s solar modules — began withdrawing the VAT export rebate that long kept its panels artificially cheap. Industry voices expect this alone to lift module prices by around 10% over time. War supplied the spark; policy is the slow burn.

Closer to home, market trackers reported that while average rooftop system costs held broadly steady in the first quarter, systems built on imported Chinese modules already showed a clear uptick. Gujarat, meanwhile, continues to lead the country — accounting for roughly a quarter of India’s total rooftop solar installed to date.

Here is the irony worth framing on a wall: the very war making panels dearer is also making solar more valuable than ever. When oil and gas spike, every rooftop that runs on the sun becomes a shield against tariff shocks. In March alone, solar generation reportedly saved Europe over €100 million a day by cutting fuel imports. The sun, as one analyst put it, does not care what happens in the Strait of Hormuz.

For a Vadodara home or a factory in Ahmedabad, Surat or Rajkot, the maths is simple. Grid tariffs only move in one direction during an energy crisis — up. A solar system bought today freezes a large slice of your power bill for 25 years. The question is no longer whether to go solar, but whether you lock today’s rate before the next price revision lands.

There is a second wallet the Gulf crisis is hitting: the one at the petrol pump. As crude climbs, every litre of fuel gets dearer — and that is exactly why solar-powered EV charging is having a moment. Pair a rooftop or solar carport with a home or commercial EV charger, and your car effectively runs on sunshine instead of imported oil. One system, two bills frozen — electricity and fuel both.

Experts agree markets rarely react overnight — much of the raw-material cost is still working its way toward the customer over the coming months. That lag is precisely the opportunity. The monsoon is the smartest time to plan: lock your quote now while prices are still soft, complete the paperwork and subsidy approval through the rains, and install the moment the skies clear. Quotes signed now can still capture pre-revision pricing and the full PM Surya Ghar subsidy; quotes delayed risk catching the wave on the way up.

In short: the cheap-solar decade may be pausing for breath. For Gujarat’s households and businesses, 2026 is shaping up to be less about waiting for prices to fall — and more about acting before they rise.
