Yes, Solar PV systems can be easily dismantled and moved. However, the exact possibility depends on the structure on which your solar panels are installed. If the built of your rooftop is as such that dismantling the panels will damage the rooftop, then moving the solar system might not be a good idea. It might cost you for the renovation of the rooftop as well as the dismantling and the installation cost of the solar system in the new location. 

If you have gone solar under the RESCO(PPA) model, then the transferring rights of the solar system will depend on the contract that you have signed with the solar system owner/installer. This might also affect the terms and conditions of the contract and therefore you should discuss the movement with the system owner/installer. 

Relocating the solar system might also affect the insurance and the warranty benefits of your solar system. If you own the solar system, do check the warranty and insurance details before making the relocation.
