1.
How can I install solar PV systems?
You would need to go through the following steps to install solar PV systems:

i. Apply to SP Services (SPS) for solar PV connection. This could be done through the appointment of a Licensed Electrical Worker (LEW); and
ii. Apply for the relevant licenses (see Qn 2) before turning on your solar PV system.

More information can be found on Singapore Power's Solar PV website.
2.
Do I need a licence to install solar photovoltaic (PV) systems to offset my electricity consumption?
You may require up to two licenses to install a solar PV system.

i. Electrical Installation Licence
An Electrical Installation Licence is required to use or operate any electrical installation, including a solar PV system. It is imposed on non-residential electrical installations with demand exceeding a certain threshold (45 kilovolt ampere or kVA). In addition, you will need to appoint the appropriate class of Licensed Electrical Worker (LEW) to handle the electrical installation. The LEW is also able to assist in the application for the Electrical Installation Licence.

ii. Electricity Generation Licence
For a solar PV system, the aggregate of the AC inverter capacities at the point of connection to the grid will be used to determine the threshold for licensing requirements. The point of connection refers to the point where the solar PV system is connected to SP PowerAsset's substation.

If your solar PV system exceeds 1 MWac (measured in terms of aggregate inverter capacity at the point of connection to the grid), you would need to apply for a licence from the EMA.
3.
Can I be paid for excess solar electricity sold back to the grid?
You are required to register with the Energy Market Company (EMC) to receive payment for excess solar electricity sold back to the grid based on the prevailing nodal prices.
4.
Where can I find more information on the payment and regulation for solar PV system?
More information can be found on Singapore Power's Solar PV website.
