In an effort to learn more about Labview, I built a solar power log for a 5W panel that I bought from Harbor Freight Tools. This is built using copy of Labview 8 Student Edition that I bought from Powell's book store. The hardware interface uses a DAQCard 1200 PCMCIA card. The power is measured using a simple power resistor and a current sense resistor.

Here's a sample of the data:

Here's a screen shot of the interface:
