SolarCity may not have raised as much in its initial public offering than it had once hoped. But at its lowered offering price, the solar power company found more than a few takers.

During the first day of trading, the company’s stock jumped as much as 59 percent. The stock closed on Thursday at $11.79, or 47.4 percent above its offering price of $8. That valued SolarCity at $861 million.

The strong market debut followed a few days of difficulty for SolarCity and its underwriters, none of whom fully prepared for issues in bringing a clean technology company to market.
