Consumers with solar PV system less than 1 MWac

Residential Consumers
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? No licence is required for residential installations less than 1 MWac.
3.	Can I be paid for excess solar electricity sold back to the grid? Currently, any solar energy produced is first used to offset your own consumption during that period. Any excess solar energy will be exported to the grid. You will receive payment (based on the prevailing low-tension electricity tariff minus grid charge) from SP Services by way of a credit adjustment to the monthly electricity bill.
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.
Non-Residential Consumers

2.	Do I need a licence to install solar photovoltaic (PV) systems to offset my electricity consumption? 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.
3.	Can I be paid for excess solar electricity sold back to the grid? Yes, consumers can be paid and the amount of payment received depends on their contestability status. Currently, for non-contestable consumers, any solar energy produced is first used to offset your own consumption during that period. Any excess solar energy will be exported to the grid You will receive payment (based on the prevailing low-tension electricity tariff minus grid charge) from SP Services by way of a credit adjustment to the monthly electricity bill. For contestable consumers, EMA has implemented the Central Intermediary Scheme with effect from 1 April 2015 to allow you to be paid the average nodal price via SPS for the excess solar electricity sold back to the grid. Alternatively, you can also 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. Currently, a commercial and industrial consumer with an average monthly electricity consumption of at least 2,000kWh is eligible to become contestable. Instead of buying electricity at the regulated tariff from SP Services, they can choose to buy electricity from electricity retailers.
