T1 Energy’s October 30, 2026 announcement reports new solar-module offtake deals totaling more than 1.58 GW, with expected supply in 2027 and 2028. The same release says more than 4 GW of its 2027 manufacturing capacity is now under contract. Those figures have different time scopes and are not presented as two independent amounts to add.

Label the contract group and year
T1 expects supply from G1_Dallas. The release does not split the new volume between the two years. Reconcile that allocation with the annual total before combining figures.
Signed future supply and completed shipments are different milestones. Keep the contract announcement separate from later production and delivery evidence.
Try a small fictional ledger
Imagine an invented supplier with three order rows, measured in arbitrary units. Customer A has 80 units scheduled for Year One. Customer B has 20 units in Year One and 30 in Year Two. Customer B’s newly signed deal therefore covers 50 units across both years.
The supplier’s Year One contracted total is 100 units: A’s 80 plus B’s 20. Adding the 50-unit new-deal figure to that 100 gives 150, but it counts B’s Year One allocation twice and also brings Year Two into the result. The distinct volume across all three rows is 130.
These are fictional teaching numbers, not T1 contract allocations. They illustrate why a deal-based total and a year-based total cannot be combined merely because both use the same unit. The real announcement does not provide the detailed ledger needed to calculate their overlap.
Build a reconciliation before calculating
For your own worksheet, give each order a reference, customer, delivery year, quantity and source date. Let a multi-year agreement occupy several rows, with one allocation per year. Keep an unresolved allocation visibly blank rather than distributing it equally without evidence.
Calculate an annual total from the year rows and a deal total from the contract reference. Then ask whether a newly announced agreement is already included in the annual summary. A reconciliation should explain that relationship before anyone produces a combined headline.
If a later update changes a delivery year, preserve the old observation and add the revised one with its date. Check whether the reported movement reflects a new order, a rescheduled allocation or actual delivery. Those events answer different questions even when the quantity remains unchanged.
No underlying contracts, customer schedules or manufacturing records were reviewed for this article. The proposed worksheet is an analytical aid, not a reconstruction of T1’s order book or a forecast of revenue. Its purpose is to keep periods and overlapping totals visible before doing arithmetic.
Can the totals be added?
