In order to monitor solar panels in a power line system can i use the spyder or do I still need two MTU's.

It depends on what accuracy and precision you want and whether you want to use the built-in support for generation in Footprints. If the accuracy and precision (less than a certain minimum value, dependent on the CT rating, reported as zero) of the Spyder is adequate for you and you are going to download the data and manipulate and display it outside Footprints, then you should be able to use a Spyder CT. In most solar applications, a second MTU and main CT set will work better.

I wouldn't use a spyder for solar you give up too much flexibility.  Using 2 MTU's allows much more flexibility when looking at the data and doing comparisons and as mentioned above, you give up a tremendous amount of accuracy.
