First Solar's $13.6 Billion Backlog Sets a High Bar for New Orders

First Solar ended June with 45.1 gigawatts of contracted module sales worth about $13.6 billion. That backlog is the strongest part of the investment case because it provides delivery visibility through 2030 and ties much of the order book to demand for U.S.-made equipment.

The headline value needs context. Dividing $13.6 billion by 45.1 gigawatts implies an average of roughly 30 cents per watt across the backlog. That is a portfolio average, not a guaranteed realized price. Product mix, delivery timing, contract adjustments, domestic-content benefits and cancellations can all change the economics.

Roughly 41 gigawatts of the backlog include some form of domestic-content requirement, and First Solar's fully integrated U.S. factories were substantially committed through 2028. The company also booked about 1.9 gigawatts of new U.S. orders between its recent earnings calls at roughly 36 cents per watt. That compares with about 20 cents per watt for Indian bookings in the first half, showing why U.S. policy support and local manufacturing remain central to margin expectations.

The latest quarter also shows that backlog is not the same as cash. Second-quarter revenue fell to about $1.06 billion from $1.10 billion a year earlier, largely because the prior-year period included revenue tied to customer contract terminations. Net income rose to $422.6 million from $341.9 million as cost of sales declined. Operations used $360 million of cash in the first half, compared with $458 million a year earlier, while factory expansion and working capital continued to absorb funds.

Contract changes remain a real risk. First Solar recorded only 0.2 gigawatt of de-bookings in the first half, but customer terminations can alter revenue timing and economics. Management also faces volatile commodity costs, underused-factory expenses and uncertainty around trade and energy policy.

The next report should be judged on three linked numbers: new bookings, cancellations and cash conversion. The backlog gives First Solar a cushion that many solar manufacturers lack, but the stock's durability depends on replenishing that book at attractive U.S. prices while turning signed volume into cash.
