Mistake = Good news

Taking the advice of some postings, I purchased a Kill A Watt to get a more accurate measurement of the watts my computer system pulls. When using my system, the following components draw power.

• Mac mini (1.5 GHz Intel Core Duo)
  
• Mac 20" display
  
• Lacie 500GB external hard drive
  
• JBL Duet 2.0 speakers

These components pull 75 watts of power. 

• Airport
  
• Cable modem

These components pull 5 watts of power.

So instead 197 watts like I previously thought, I'm only looking at 80 watts. This is great news. I only need to collect 320 watt hours of solar power to run my computer system for 4 hours over the weekend.
