energy used on-site vs sold energy

I’m reading the new version of the reference guide and I have some doubts concerning this credit. As example, within the LEED boundary electricity is produced by pv panels. Part of the electricity is used onsite, while when the produced energy is more than the needed energy a part is sold. The owner of the pv system is also the owner of the building. Can the project team consider for the achievement of the credit both the renewable energy used onsite and the sold renewable energy? Only if RECs are purchased for an amount equal to the total renewable energy produced (used onsite + sold)?
