The future of solar energy is certainly looking bright, and solar stocks have tremendous potential right now. These stocks can be quite volatile, which is why I've placed them in the Aggressive category of my Blue Chip Growth Letter.

For instance, First Solar (FSLR) posted fourth-quarter earnings yesterday of $0.77 per share--consider that in the year-ago period, it earned just $0.11 a share! You can see how much this company has taken off. First Solar also reported $201 million in revenue. The company was able to reduce its costs while increasing its sales. That's what I like to see!

Analysts had forecast earnings of $0.53 cents per share, which means the company posted an outstanding 45% earnings surprise. In fact, FSLR ended the day a whopping 30% higher! That's the power of superior fundamentals.

Analysts are scrambling to raise their estimates on First Solar, and I continue to maintain high hopes for this company. If you haven't gotten in on it yet, I'll be calculating a new Buy Below price in my March Blue Chip Growth issue. Look for it online this Tuesday, February 19.
