200 billion PHP is 3.58 billion USD. The farm is 3500 MW and has 4000 MWh of battery storage. As of today 1 Wp (peak watt) of mainstream solar panels costs about 0.16 USD [1], and 1 kWh of li-ion battery costs about 140 USD [2]. Which means the panels alone cost 560M USD, and the batteries also cost 560M USD, so combined they represent 31% of the total 3.58B USD budget. It seems to be not very cost-efficient, as the overhead for everything else (2.46B USD) is quite large: inverters, mounting hardware, grid connection, installation, inspection, etc. Edit: I was basing my "not very cost-efficient" remark on the fact that this solar plant is basically $1.00/W however the best utility-scale solar plants achieve about $0.80/W, or 20% less. However I forgot to account for the fact this plant has batteries, so a higher overhead is expected. So, after all, the capex is in line with what I'd expect.
