Thus, the LCD only can display the value not above 5 volt,am I right??
If this is the case, if I want to display value above 5v on the LCD then is that possible.

Hi DragonBall_6,
What the voltage divider does is input voltage based upon the resistors ratio into the pic pin and hopefully limit it's input voltage to TTL levels. You have to write the code to do the math and then output the voltage numbers to suit your purpose. If you store the ADC value in a byte variable then ( and I am going out on a limb here as I am as new to pic programming as you are ) you should be able to express that as a number from 0 to 255. So if 5 v = 255 (input pin at 5 v when solar panel is at 15 volts) then 255 = 15 volts.So with a given voltage divider you can express 15 volts incremented in 255 steps. Anyone out there who is more knowledgable please ring in!
