Solar Stocks Surge 29% in a Month, Up 6% Today

NextPower Inc. (NASDAQ: NXT), a solar tracking systems provider listed on the Nasdaq, closed at $121.37 on February 5, up 6.09% for the day. Trading volume reached approximately 1.5 million shares, and the company’s market capitalization climbed to about $18 billion—roughly 24 trillion Korean won—adding some $1.2 billion (around 1.6 trillion won) in value in a single session. Over the past month, NextPower’s shares have risen about 29%, and year to date they are up more than 140%.

The rally follows the company’s better-than-expected third-quarter fiscal 2025 results, which beat analysts’ revenue and profit estimates and prompted NextPower to raise its full-year sales guidance. Following this “beat and raise,” KB Bank upgraded its rating on the stock and several firms lifted their price targets, driving shares to fresh all-time highs. Meanwhile, insider activity was also noted: director William Watkins sold 5,000 shares on January 30.

NextPower, headquartered in Fremont, California, is a renewable-energy technology company that supplies utility-scale and distributed solar plants with compact, rotating trackers, power equipment, and related software. Since its Nasdaq listing in 2023, the firm rebranded from Nextracker to NextPower in 2025 and has expanded its offerings into integrated solar solutions by combining AI and robotics with power hardware.
