217 GW of Module Capacity, Nowhere Near the Demand: Insuring Idle Solar Factories

In August 2026 the Ministry of New and Renewable Energy added 12,724 MW of solar module capacity to ALMM List-I, taking cumulative listed module manufacturing capacity to 217,107 MW, as reported by PV Tech and Energetica India. SolarQuarter recorded MNRE's 50th ALMM revision on 4 August 2026 alone adding more than 11.5 GW of new module capacity. The additions were not marginal: PV Tech reported Adani New Industries adding 4,781 MW from a new plant in Kutch, Gujarat, Fujiyama Power Systems adding 1,014 MW from Dadri, Uttar Pradesh, and four new entrants contributing a combined 1,638 MW.

Annual domestic solar installation runs far below 217 GW. The consequence for the manufacturing base is arithmetic rather than opinion. Listed capacity is a permission to supply, not an order book. Across the sector that gap shows up in three physical and financial forms at once: lines running well under nameplate throughput or standing idle for stretches, finished modules accumulating in factory yards and third-party sheds because they were built ahead of an offtake, and receivables stretching as buyers hold cash against a falling module price.

Each of those three is an insurance problem before it is an accounting one. An underinsured, partially operating factory with a swollen stock pile and a concentrated buyer book is a very different risk from the same factory running at full tilt and shipping to schedule, and almost none of that difference is visible in a renewal submission that simply repeats last year's numbers.

Indian fire wordings, and the special-perils covers built on them, carry conditions that assume a working factory. Two matter here.

The first is the unoccupancy condition. Fire wordings in the Indian market have long required the insured to give notice where the insured premises, or a building containing insured property, remain unoccupied for a continuous period beyond 30 days, with cover capable of being suspended or voided if that notice is not given. A module line that stops for a monsoon quarter, a shed emptied of staff while only a security contractor visits, or a second unit mothballed pending orders can all trip that condition without anyone in the finance team realising a policy condition has been engaged. The same mechanics are covered in more depth in the post on unoccupied premises and vacancy warranties in property underwriting, and the analysis applies directly to a mothballed module bay.

The second is the alteration and cessation-of-business condition. Fire wordings typically respond to any material alteration in the risk, including the ceasing of manufacture, without written insurer agreement recorded by endorsement. Partial operation frequently comes with exactly the changes underwriters want to know about: reduced shift cover, a skeleton maintenance crew, sprinkler or hydrant pumps left unattended, a fire-detection panel in permanent fault because nobody is on site to clear it, and a plant where hot-work permits get issued by someone with no line responsibility.

The stock number in a solar module placement is usually set at renewal from last year's peak. In an oversupplied market that number goes stale in one direction only. Modules are built, they are not lifted, and the yard fills.

Under the sum insured logic of a fire policy, the consequence is the average clause. If the declared stock value is INR 80 crore and the actual value at risk on the day of the fire is INR 140 crore, a partial loss is scaled down in the ratio of declared to actual. On a stock pile that has quietly grown for three quarters, that reduction can be larger than the deductible by an order of magnitude, and it applies to every partial loss, not only a total one.

The declaration policy exists precisely for stock that fluctuates, and Indian fire declaration wordings, carried over from the erstwhile All India Fire Tariff, run on a specific mechanic:

• The policy is available on stocks where the sum insured is at least INR 1 crore.
• A provisional premium is paid at inception, with the balance adjusted at expiry against declarations.
• The insured declares the highest value at risk during each month, by the agreed date.
• Where a declaration is not filed, the full sum insured is deemed to have been declared for that month, so the insured pays for cover it may not have needed.
• The sum insured operates as a ceiling. Any value above it on the day of loss is uninsured regardless of what is declared.

That last point is where oversupply bites. A declaration policy does not protect an insured whose stock has grown past the ceiling; it only makes the premium fairer below it. A module maker whose finished-goods pile has doubled needs the sum insured raised, not merely the declarations updated.

Accumulated finished goods change the plant's loss profile as well as its balance sheet. A module is glass, an encapsulant film, a polymer backsheet on most product lines, an aluminium frame and a junction box. Stacked in pallets, the fire load is concentrated in the polymer content, and stacked outdoors it is exposed to hail, wind uplift, flood and ground water in a way that a module on a mounting structure is not.

Three consequences follow for the placement.

1. PML rises with density. A yard packed to the fence line removes the separation distances the original survey assumed. The estimated maximum loss the underwriter priced against the plant may no longer describe the site, which matters for both rate and for the reinsurance the insurer arranged behind it.
2. Storage location drifts off the policy schedule. Overflow stock goes to leased sheds, transporter yards and port storage. Fire cover is location-specific. Stock sitting in a third-party warehouse that was never added to the schedule is uninsured, and a floating policy over declared locations is the correct instrument when stock genuinely moves between named sites.
3. Storage duration erodes recoverability. Modules held long enough in an open yard invite claims about pre-existing degradation, and a fire or flood loss on aged inventory attracts arguments over whether the loss reduced a value the market had already written down. Establishing book value and condition before an event is much easier than after one.

The underlying point in the renewable energy insurance discussion holds here too: on solar assets the argument at claim stage is usually about value and condition, not about whether the peril operated.

Business interruption on an underutilised factory is one of the harder conversations in a 2026 renewal, and getting it wrong costs the insured twice.

The gross profit declaration is built from turnover, and turnover on a line running at a fraction of nameplate is low. Declare against that low figure and the insured is protected only for what the plant recently earned, which understates the exposure if orders return during the policy year. Declare against nameplate and the insured pays premium on gross profit it is not earning, and still faces an adjustment argument at claim stage because the loss adjuster works from actual trading results in the twelve months before the incident.

The practical route through is to be explicit rather than to pick a number and hope. Three items to settle at placement:

• Whether the BI basis should be turnover or an output basis that better reflects a plant with committed capacity and lumpy despatch.
• Whether the indemnity period genuinely survives an equipment loss on imported lamination or stringing tooling, where reorder lead times run in months rather than weeks.
• Whether the trend and other-circumstances clause is being read as a floor or a ceiling by the insurer, since a market with falling module prices makes the standard adjustment clause work against the insured.

For a module maker in an oversupplied market, the credit risk is structural. Sales concentrate in a handful of large EPC contractors and developers, credit periods lengthen because buyers know they hold the pricing power, and one delayed utility-scale project can strand a full quarter of despatch value in receivables.

Trade credit insurance is the right instrument, but it behaves in ways that surprise first-time buyers when the underlying exposure is concentrated.

What the cover will and will not absorb

The IRDAI (Trade Credit Insurance) Guidelines, 2021 opened the product beyond the whole-turnover model that preceded them, allowing single-buyer and selected-buyer structures and permitting cover to be extended to banks and factoring companies with an insurable interest in the receivable. They also require the seller to retain a share of the loss, with indemnity capped short of 100 percent, so a concentrated book cannot be fully transferred.

The mechanics that decide whether a policy pays are in the credit-limit machinery rather than the headline limit:

1. Approved limits per buyer. Cover attaches only up to the limit the credit insurer has approved for that buyer. Despatch beyond it is uninsured even though the policy is in force.
2. Limit cancellability. Most Indian trade credit wordings allow the insurer to reduce or withdraw a buyer limit for future despatches. In a stressed sector limits get cut exactly when the seller most wants them, so a non-cancellable or notice-period structure is worth paying for.
3. Discretionary credit limits. Small buyers can be covered on the seller's own assessment up to a stated cap, but only if the seller can evidence the credit checks the wording requires.
4. Maximum extension periods. Cover assumes payment within the agreed credit period plus a stated extension. Informally letting a large buyer run past that window can void the claim on that receivable.
5. Notification of overdue accounts. Missing the notification deadline on an overdue invoice is the most common reason an otherwise valid trade credit claim fails.

A module maker with 70 percent of its receivables against three buyers should expect the credit insurer to price and structure around those three names specifically. That is the correct outcome. The mistake is buying a whole-turnover policy, assuming the concentration is diluted by it, and only discovering at the first default that the approved limit on the largest name was a fraction of the outstanding balance.

The reason to act at renewal rather than after an event is that every issue above is cheap to correct in advance and expensive to argue afterwards.

1. Restate stock values honestly. Take the actual peak finished-goods and work-in-progress value over the last four quarters, not last year's declaration, and set the sum insured above the realistic peak. Where the stock genuinely swings, move to a declaration policy and diarise the monthly filing so the deemed-full-declaration clause never fires.
2. Schedule every storage location. Include leased sheds, transporter yards and port storage, and use a floating cover over named locations where stock moves. An unscheduled location is an uninsured location.
3. Disclose the operating pattern. Tell the underwriter which lines are running, which are idle, what the shift and watchman arrangement is, and how long any bay has been shut. Record it by endorsement so the unoccupancy and cessation conditions cannot be raised later.
4. Keep protections live on idle plant. Hydrant and sprinkler systems, detection panels, and hot-work permitting need to work on a quiet site, and any impairment needs to be reported to the insurer at the time, not explained after the loss.
5. Re-cut the BI declaration and the credit limits together. Both depend on the same trading assumptions. A gross-profit figure built on a hoped-for order book and a credit limit built on last year's buyer mix will not survive the same year.

The insured who walks into the renewal with a current stock valuation, a schedule of every location holding modules, an honest statement of which lines are idle, and a buyer-by-buyer receivables ageing will get better terms than the one who repeats last year's proposal form. Oversupply is a market condition. Underinsurance is a choice.

The upstream side of the same policy shift is covered in the solar cell gigafactory risk profile: ALMM List-II pushed cell capacity into a build wave while List-I module capacity ran ahead of demand. Brokers placing anything in this chain need to know which side of that imbalance their client sits on, because the exposures point in opposite directions. A cell line is short capacity and long process hazard. A module line is long capacity and long working capital.
