The law terminates 45Y/48E for affected solar and wind facilities placed in service after 2027 when construction begins after July 4, 2026\. For financing purposes, the tax analysis should be translated into a closing-condition matrix rather than left as a tax-counsel workstream that sits outside the lender model. A lender should run two schedules: one preserving the pre-deadline construction position and one assuming the project misses it. The second case needs to test whether COD before 2028 remains realistic and whether the project still closes if the credit disappears. This keeps the tax-credit source of funds tied to the exact diligence items that determine whether the proceeds arrive on time and in the amount assumed. ## Underwriting Tests for Solar Beginning Construction July 4 2026 - **1.** physical work of a significant nature. - **2.** binding written contracts for off-site work. - **3.** continuity requirement. - **4.** low-output exception where relevant. - **5.** critical-path construction schedule. - **6.** placed-in-service before 2028. ## Documents Required for Solar Beginning Construction July 4 2026 The lender file should let a credit committee reproduce the assumption without relying on management narrative.
