Comparation between common controller and our MPPT controller
 photo 2-24_zpsa8581aef.jpg        photo ccccc_zps3293bd97.jpg    
       <Picture 1 > on charging when using common controller                           < Picture 2> on charging when using  our MPPT  controller
 As we know that W=V x I, so from pic. 1, we get the power is 12x5.54=66.5w.
But from our MPPT charge controller, you can get the power up to 18x5.54=12x8.31=100 WATT ! (see pic. 3)
Therefore, when the Vpmax= 18v, Battery voltage Ub=12v, the Eff= 100/65= Vp/Ub=18/12=1.5.
In other words, the MPPT controller can increase nearly 50% efficiency than the common controller.
While in practical use, the efficiency will be effected by the temperature, sunshine, conversion efficiency, etc..  so usually a good MPPT can increase the efficiency up to 15-30% for you.
