• Two equal solar panels were exposed to the real sun and conversed electrical power was measured.
• Test conditions:      
• Solar panels (both):    200W (producer spec. at AM 1.5)
• Date:                       July 2005
• Time:                       4:00 to 20:00 (sun time)
• Geo. Latitude:           46° N
• Weather conditions:   sunny, but not totally clear
• Results:       
• Average energy of fixed:                 836,8Wh
• Average energy of motorized:        1354,0Wh
• Note: sum of motor energy consumption through all day is 5,84Wh or 0.43% of all collected energy.

Efficiency of motorized panel: 161,1% against fixed panel in a sunny day.
