Albuquerque-based Array Technologies Inc. expects its annual revenue to blow past $1 billion in 2021. If accurate, that would represent a monumental achievement for the homegrown New Mexico manufacturing firm, which makes solar tracking systems for photovoltaic panels. The company, which went public in October on the Nasdaq Global Market, reported $872.7 million in revenue for 2020, reflecting a 35% jump over the $647.9 million it reported in 2019. Its net income grew by 49% to $59.1 million last year, up from $39.7 million in 2019. Now, the company is projecting another 30% jump in revenue for 2021, potentially climbing to $1.13 billion. It already has $654 million in backlogged orders scheduled for delivery this year, said Array Chief Financial Officer Nipul Patel in a year-end earnings conference call Tuesday.
