@ Mr Prasad its a temporary project.
 

I think, you need to obtain GST registration (Normal) in the respective States in which you are planning to effect supply. You can obtain temporary registration as Casual Taxable Person only if you occasionally undertake transactions. Validity of Casual Taxable Person is only 90 days. So depending on the project, you may decide.

Yes, you should consider registering for GST separately in Madhya Pradesh and Uttar Pradesh for your solar project.
