Solar module manufacturer Waaree Energies is increasing the capacity of its solar module manufacturing plant in Arizona in the U.S. from 1 GW to 1.6 GW by investing $37 million.

Following the expansion, the company’s aggregate manufacturing capacity in the U.S. will increase to 4.8 GW. This will comprise 3.2 GW of manufacturing capacity in Texas and 1.6 GW in Arizona.

The revamp will involve replacing the Arizona facility’s existing module manufacturing lines with new high-efficiency module production lines.

Waaree said the investment will be funded through a combination of debt and internal accruals.

The board also approved consolidating Waaree’s manufacturing facilities in Gujarat. The company will relocate plant and machinery from its 1 GW Tumb facility and 1.11 GW Nandigram facility to its existing manufacturing facility at Chikhli, Gujarat.

Waaree said the consolidation is being undertaken for operational efficiency and is expected to be completed on or before December 31, 2026. The Tumb and Nandigram facilities together contributed approximately 14% of the company’s standalone turnover during the previous financial year.

Mercom had reported that during the first quarter of the financial year 2026, Waaree’s total solar module production increased 41.5% year-over-year to 3.24 GW, while module sales reached 3.6 GW. The company had 25.8 GW of installed solar module manufacturing capacity and 5.4 GW of solar cell capacity. Capacity utilization at its U.S. module manufacturing facility stood at 59%.
