GSPARX is a wholly owned subsidiary of TNB that focuses on green retail generation business. At the moment, our focus is in the investment of rooftop Solar PV for all retail customers.

GSPARX offers a solution for customers interested in solar PV self-generation and selling the excess of solar energy under the Net Energy Metering Scheme (NEM).

We install solar PV system on your rooftop. the energy generated by solar will be used by your house to power all the electrical appliances. That means you buy less from TNB whenever sun is shining.

If there is an excess or balance of energy, it will automatically flow to TNB grid. And if package your installation with NEM, you will get credit for the excess energy to further reduce your bill. The rate of selling to TNB is the same rate as buying.

GSPARX is offering a package that include NEM where the house/building consumes the solar energy first and sell the excess to TNB and get credit for it.

We have 2 specific programs for customers:

  1. Residential customers
    For Residential customers, we offer a standard package of 3,5,6,8,10,12 and 15 kWp system. Nevertheless, we do cater for bigger size installation after site assessment is made.
    There are 3 payment options available:

    • Cash Purchase- pay lump sum amount
    • Credit Card- We have a special instalment plan with Maybank for 12,24 and 36 months. For other banks, only the one-off swipe is available
    • Personal Loan- Finance the PV system via personal loan. Choose your preferred bank. Special rate by Bank Islam for GLC employees.
  2. Commercial & Industrial (C&I) customers

    • For C&I customers, we have a special payment plan called SPPA.
    • Key features of SPPA are:
      1. Investment will be done by GSPARX, hence ZERO Capex/ No upfront cost from the customer.
      2. Solar tariff will be discussed between customer and GSPARX. The intention is to offer lower tariff than the grid tariff, hence providing IMMEDIATE electricity cost savings for the customer.
      3. The solar tariff could be fixed throughout the tenure, hence provides hedging for future grid tariff increase.
      4. If there is additional energy expected to be supplied to the grid, we would highly recommend for the customer to sign up with Net Energy Meter program (NEM). Under NEM, the excess energy generated by solar and exported to the grid will be on a one-on-one offset i.e. no difference in the sale and purchase prices of electricity. You can read more about NEM at
      5. Maintenance of Solar PV system will be taken care throughout contract period.
    • Other payment plan i.e. cash is also available for C&I customers.
    • Please register your interest at our website or at this link: We will contact you. Please be ready with your location and a snapshot of your bill. Availability of historical record of your electricity consumption would help a lot!

No. The program that you refer to is Feed-In Tariff (FIT). FiT allows customer to install on their rooftop and sell all energy produced to TNB and get paid for it. The Government has stopped offering new quota for Solar PV. Our product is packaged with NEM.

The concept of NEM is that the energy produced from the solar PV system installed will be consumed first, and any excess to be exported to the distribution licensee (such as TNB /SESB ).

The priority is for self-consumption, however some premises especially industry or manufacturing companies which may not be operating during the weekends may have excess energy exported to the grid.

In return, customers account will be credited at the prevailing customer rate based on the 1:1 NEM announced by the YB Minister earlier. The credit shall be allowed to roll over for a maximum of 24 months. Read more about NEM at SEDA website.

Yes, if the customer’s consumption pattern demonstrated significant potential for surplus to be transmitted to the grid, we highly encourage customer to sign up for NEM to maximize the benefit of installing solar PV. We will advise you accordingly on the NEM registration.

For customers with consumption pattern less likely to have potential surplus, NEM registration might not be required. However, we could register at customer’s request.

For residential customers, our package is inclusive of NEM. This is because for houses, the consumption of your house during weekdays/daytime is usually lower than what your solar PV system can produce. As such, with NEM, the excess energy that will automatically flow out to TNB grid will be compensated in terms of further credit to your bill.

In a simple terminology, in Malaysia, the Feed-In Tariff (FIT) scheme, allows the customers who is the Feed-in Approval Holders (FIAHs) to sell all electricity produced from Renewables resources to Distribution Licensee, such as TNB at the FiT rate.

In Net Energy Metering (NEM), on the other hand, the electricity produced by the solar PV system must be consumed first, and only excess can be exported to the grid at one to one rate.

No, because at the moment the cost of the battery is high making it not commercially viable to install solar PV with battery. We are closely monitoring the price and as a GSPARX customer, you will be amongst the first group of customers to own the battery when it is commercially viable soon.

However, with NEM that allows you to sell excess energy to TNB and be paid at the same rate as you buy from TNB, TNB becomes your ‘battery’ and you save the investment on the storage unit.

For PV module, we only use Tier 1 PV module i.e. Q-cells and Jinko.

The final choice of brand equipment that we will install is subject to final design and site assessment.

We use only the leading brands in inverter technology such as Sungrow. We give a manufacturer warranty of 5 years. You can also opt for an extended warranty.
