Are Negative/Positive terminals of solar panel plate connected to ground(its metallic frame) or are independent and floating points.

I am wondering if frame is connected to ground may cause grounding problems
 

The metal frame should not be wired to the PV panel's positive or negative lead. If lightning were to strike you'd have it going into your electrical system. Bad news.

Often panels are fastened together as a structure, in which case they are supposed to have a lightning/ static discharge cable to earth ground.
 
The panels I have are rated for 1Kv operation above the surrounding aluminium frame, which I believe is fairly standard.
No problem in connecting a long string of panels in series to operate at high dc voltages.

If bolting the aluminium surround onto a steel frame, it's probably a good idea to have low voltage insulation to prevent galvanic corrosion. Many people do not bother and do not seem to have a problem. But if near the sea, its probably something to think about.

As Brad says, if the panels are very high, lightning could be an issue.
And if on a steel roof, always be aware of the possibility of electrocution.
A two pole isolating switch is usually a requirement for higher voltage systems.
 
By default metallic frame is not connected to any terminal(Positive/Negative) of panel plate?
 

The metallic frame is isolated from the positive and the negative terminals of the panels. Generally speaking, during an installation, you by default provide a ground path for the frame via the installation channels

Metallic frame is completely isolated with insulation that has a high voltage rating.
