The rooftop solar PV station is mounted on the campus of St. Mary’s University located at Bayombong, Philippines. The installation incorporates eight hundred fourteen (814) photovoltaic panels and six (6) grid-tied inverters for own consumption and when needed allowing for excess electricity to be fed back into the national grid. With a grid-tied inverter the rooftop solar PV station is grid interactive.
Real-time performance monitoring of the solar PV station is available and the system generates about 299,500 kWh per year. The project enables the school to reduce a total of about 129.5 metric tons of CO2 emissions per year at the same time. These carbon emission reductions are equivalent to burning 55,160 litres gasoline less per year.
