Claim:
1. A method for assembly of a root portion extension panel at a wind turbine site to at least one of a leading or trailing edge of a previously manufactured wind turbine blade, said method comprising: attaching a mold to one of the leading or trailing edges adjacent to a root of the wind turbine blade, the mold extending span-wise from adjacent the root along one of the leading or trailing edges towards a tip of the wind turbine blade, the mold having a chord-wise dimension so as to extend inwardly and terminate at an intermediate position between the leading and trailing edges so as to not surround the root, the mold extending outwardly in a chord-wise direction beyond the leading or trailing edge; injecting a viscous material into the mold; allowing the viscous material to cure into a hardened state that adheres to the respective leading or trailing edge and defines a core of the root portion extension panel; and wherein the root portion extension panel does not surround the root portion and extends from the intermediate position outwardly to the leading or trailing edge and changes an aerodynamic chord-wise length and shape of an inner board area of the wind turbine blade adjacent the root.
