Est. PV output: Estimated solar photo-voltaic (PV) output

Installed PV cap: Installed solar PV capacity

MWac: Nominal power output in megawatts (MW), converted to alternating current

Installed solar PV capacity refers to the total capacity of solar PV installations in Singapore. This is measured in MWac, which refers to the capacity of the inverters used in solar PV installations.

Electricity from solar can vary based on factors such as the amount of sunlight, cloud movement and shade. On a cloudy day, for example, there will be less solar PV output. This solar irradiance heat map shows the solar irradiance variations across Singapore.
