I've been working on renewable especially on solar since 2001.
Capacity declered (MW) were based on AC (actual generating capacity export) - no need loss factore excep for technical transmission loss) which very insignificant as menergy meter were located no far from solar farm.
Plus point for solar power:
1. constant revenue with quit consistant energy yield for contract tenure.
2. Good cash flow as TNB is a very good pay-master.
3. Repair & maintenance (including scheduled inverter repalcement) already factored in financial model.
4. LSS 1 & 2 really good price for project owner.
