General information for installing solar PV

There are 3 broad steps to take when installing solar PV:
      1. Physically installing the solar PV system
      2. Commissioning and turning on the solar PV system
      3. Selling back excess solar generated electricity, if applicable


1. Physically installing the solar PV system

Consumers installing a solar PV system should engage a Qualified Person (QP) to ensure appropriate physical installation and compliance with regulations. A Qualified Person is a person who is registered as an Architect with the Board of Architects (BOA) or a Professional Engineer with the Professional Engineers Board (PEB); and has a valid practising certificate issued by the BOA or PEB, respectively. Depending on the individual consumers’ requirements, the QP may need to seek approval from the authorities, e.g. BCA (structural safety), URA, (planning permission), SCDF (fire safety), CAAS (aviation zone) for the solar PV installation.


2. Commissioning and turning on the solar PV system


After the solar PV system has been installed, the consumer should engage a Licensed Electrical Worker (LEW) to commission and turn on the solar PV system, including applying for the relevant electrical licences and assessing the electrical connection requirements. The consumer may also need to apply for a generation licence and market registration, if the solar PV system is 1MWac and above.


3. Selling back excess solar generated electricity, if applicable


If the consumer wishes to sell any excess solar electricity to the grid, he may either

      a. Register with SP under the Simplified Credit Treatment (SCT) or Enhanced Central Intermediary Scheme (ECIS) by requesting the LEW to submit the relevant applications to SP [Recommended], or

      b. Directly register with the Energy Market Company as a Market Participant, or

      c. Appoint a third-party as the Market Participant (not applicable to residential consumers).

For more information, please refer to the subsequent sections below on the various payment schemes and selling back excess solar generated electricity.

What are the payment schemes available for consumers generating solar energy?

Types of Payment SchemeDetails  
Simplified Credit Treatment Scheme (SCT) EMA has simplified the market registration process for Non-Contestable Consumers (NCC) to directly register with SP Services.

Under the SCT, NCCs that sell any excess energy to the market will be paid at the prevailing tariff minus grid charges.

More information on SCT can be found here
Enhanced Central Intermediary Scheme (ECIS)EMA has introduced the ECIS where Contestable Consumers (CCs) can register with SP Services directly, thus reducing regulatory barriers and administrative matters.

Under the ECIS, CCs that sell any excess energy to the market will be paid at the prevailing half-hourly wholesale energy prices

More information on ECIS can be found here
Register as a Market Participant (Non-Exporting)
EMA has introduced a new class of Market Participant (Intermittency Generation Sources Non-Exporting) category. Under this category, consumers will undergo a streamlined market registration process where they are not required to provide credit support or to submit generation meter readings to Energy Market Company (EMC). Consumers will not be paid for injecting any excess energy to the grid.

Consumers are required to pay EMC an estimated fixed charge on the IGS capacity only every six months. This will be based on a standardised IGS Generation Profile for all consumers.

More information can be found here

Register as a Market Participant
Consumers with solar installations will need to register as a Market Participant with Energy Market Company, subject to the relevant Market Rules. Any excess energy solar sold back to the market will be paid at the respective nodal price.

*Contestable Consumers (CCs) are those that can choose to buy electricity from a retailer of their choice or directly from the wholesale electricity market.


How to sell your excess solar generated electricity? 



Option 1: Register with SP Group under Simplified Credit Treatment (non-contestable consumers only)
 

Non-contestable consumers with solar capacity < 1 MWac will need to register with SPS under the Simplified Credit Treatment (SCT) to sell their excess solar generated electricity. Consumers will receive rebates via their monthly electricity bill.

The Net Export Rebate application form can be downloaded from SPS’ website here and submitted via SPS e-Business portal directly or by the consumer's appointed Licensed Electrical Worker (LEW) on the consumer's behalf. Alternatively, the hardcopy application form can be submitted via mail to the following address: SP Group, 2 Kallang Sector, Singapore 349277.

For further enquiries, please email install@spgroup.com.sg.



Option 2: Register with SP Group under ECIS

Contestable consumers with solar capacity < 10 MWac can register with SPS under the Enhanced Central Intermediary Scheme (ECIS) to sell their excess solar generated electricity. Consumers will receive rebates via their monthly electricity bill.

The Net Export Rebate application form can be downloaded from SPS’ website here and submitted via SPS e-Business portal directly or by the consumer's appointed Licensed Electrical Worker (LEW) on the consumer's behalf. Alternatively, the hardcopy application form can be submitted via mail to the following address: SP Group, 2 Kallang Sector, Singapore 349277.

Contestable consumers with solar capacity ≥ 1 MWac can register directly with the Energy Market Company (EMC) as a DMP or appoint a Third-Party as an MP to sell electricity on their behalf. EMC will pay the DMP or MP for the excess solar generated electricity. You will also need to register as a Generation Facility with EMC.

The Market Participant application form can be downloaded from the Energy Market Company (EMC) website here. The Generation Facility application form can be downloaded here.

Please submit the hardcopy forms via mail to the following address: Energy Market Company, Market Administration, 4 Shenton Way, #03-01 SGX Centre 2, Singapore 068807.
