Quick Summary

What Is Solar Energy Credit for SESB Bills?

Solar energy credit is the bill credit given when your solar PV system exports excess electricity to the SESB grid. Solar Rakyat Sabah allows domestic consumers to install solar PV systems mainly for self-consumption, while surplus electricity can be exported to the grid and credited against electricity bills.

The biggest savings usually come from using your own solar electricity during the day, not from exporting all of it.

How Does Solar Power Reduce Your SESB Bill?

Solar power reduces your SESB bill by lowering the amount of electricity you need to import from the grid. During the day, your home uses electricity generated by your rooftop solar panels before drawing power from SESB.

For example:

In this example, your home uses 18 kWh of solar electricity directly. That means you avoid buying those 18 kWh from SESB, which gives the strongest financial benefit.

This is why we usually review each customer’s daytime usage before recommending a system size. Homes that use air conditioners, refrigerators, pumps, washing machines, or other appliances during the day often benefit more from solar self-consumption.

What Happens When Solar Panels Produce More Than You Use?

When your solar panels produce more electricity than your home needs, the extra energy is automatically exported to the SESB grid. That exported electricity becomes energy credit based on current Solar Rakyat Sabah programme rules.

Example:

Here, 7 kWh is exported to the grid. A simple way to explain it is: extra solar power helps deduct your future electricity bill.

How Are SESB Energy Credits Used?

SESB energy credits are used to offset electricity charges based on imported and exported energy. Under the programme, imported and exported energy are considered when calculating the bill credit, based on the applicable programme rules and gazetted domestic energy rate.

Example monthly energy flow:

Instead of paying based only on 350 kWh imported from SESB, the exported 120 kWh helps reduce the bill value.

Example of a Monthly SESB Bill With Solar

A monthly SESB bill with solar is lower because part of your electricity is supplied directly by your solar PV system, while excess solar generation earns bill credits.

Your savings come from:

• 250 kWh used directly, which you did not need to buy from SESB.
• 80 kWh exported, which helps create bill credits.

As a result, your payable SESB bill is lower than it would be without solar.

Real Customer Scenario: How Solar Credit Works in Daily Life

In real home usage, solar electricity generated during the day first supplies appliances such as air conditioners, refrigerators, lighting, washing machines, fans, water pumps, and other electrical items.

For example, if your home imports 500 kWh from SESB in a month and your solar system exports 200 kWh to the grid, the bill is based on the net energy concept:

If exported solar energy is higher than your monthly imported usage, the remaining net credit can be carried forward for up to 12 months within the settlement period. However, it cannot be exchanged for cash or transferred to another SESB account. ECoS states that energy credits may only be used to offset electricity bills and cannot be converted into cash.

Why Bigger Solar Systems Are Not Always Better

A bigger solar system is not always better because unused credits may build up if your daytime electricity usage is too low. The best solar PV system size should match your SESB bill, daytime consumption, roof condition, and household needs.

When we review a home, our team checks:

This helps us avoid oversizing the system and reduce the risk of generating too much credit that cannot be fully used.

For homeowners planning their budget, our guide on choosing a solar system based on your budget explains how usage, system size, and long-term savings should be compared.

What Warranty and ROI Should Homeowners Expect?

For some homes, estimated ROI may be around 3 to 5 years, depending on system budget, electricity usage, daytime self-consumption, roof condition, and system size. A properly sized system helps improve payback because more solar energy is used directly at home.

Warranty coverage may include the following, based on the confirmed system package and product brand:

Warranty terms may vary by product brand and package. Our team explains the expected generation, payback, product coverage, and maintenance needs clearly before installation.

For cost planning, this guide on solar panel installation cost factors may help you understand the main pricing points.

As an example, a RM14,000 package may achieve an estimated ROI of 3 to 5 years for some homeowners, depending on usage, system suitability, roof condition, and daytime self-consumption. This is not a fixed guarantee, but it gives homeowners a practical way to understand payback before deciding.

What Are the Solar Rakyat Sabah System Limits?

Solar Rakyat Sabah system capacity is capped at up to 5 kWac for single-phase homes and up to 10 kWac for three-phase homes. These are maximum limits, not automatic recommendations for every house.

A smaller system may be more suitable if your daytime usage is low or your roof condition limits solar generation. Our team recommends system size based on actual SESB bill usage, not simply the maximum allowed capacity.

Applications must be submitted through an ECoS-registered Electrical Contractor Class PV Grid-Connected contractor, also known as ECCPV-GC. The contractor supports the design, installation, technical certification, and application submission process through the ECoS Energy Information System platform.

HAG Solar supports Sabah homeowners with ECoS/ECCPV-GC-related solar application guidance, documentation support, site assessment, installation, and commissioning. You can also learn more about our ECoS-registered solar system consultancy for solar planning and compliance awareness.

Based on current programme information, the programme has a total 20 MW quota available until 2028 or until fully allocated, with applications processed on a first-come, first-served basis.

Simple Illustration of Solar Energy Flow

Solar energy flow is simple: your home uses solar first, exports extra power during the day, and imports electricity from SESB when solar generation is not enough.

SESB Grid ─────────► Your Home

During the day, solar panels generate electricity for your home. At night, when there is no sunlight, your home uses electricity from the SESB grid.

How to Maximize Solar Savings for SESB Bills

The best way to maximize solar savings is to use more electricity during solar generation hours.

Useful habits include:

For quotation comparison, we also recommend checking what is included in the system design, equipment, warranty, installation scope, and after-sales support. Our guide on comparing solar PV quotations properly explains these points in more detail.
