Introduction

A solar battery system combines solar panels with battery storage to store excess solar energy for later use. It helps homeowners and businesses lower electricity costs, improve energy independence, and provide backup power during outages. In this guide, you'll learn how the system works, its benefits, and whether it's the right choice for your property.

Update: NEM Has Ended, Solar ATAP Takes Over

2026 update: The NEM (Net Energy Metering) scheme officially ended on 30 June 2025 and is no longer accepting new registrations. The current replacement programme is Solar ATAP (Solar Accelerated Transition Action Programme), effective from 1 January 2026, with cash rebates up to RM3,000 through SuRIA Home.

What Is a Solar Battery System?

A solar battery system combines solar panels, a hybrid inverter, and battery storage into one integrated energy solution. Instead of exporting all unused solar electricity to the grid, the battery stores excess energy for use during the evening, cloudy weather, or power outages.

A typical battery storage includes:

Solar panels
Hybrid inverter
Battery storage
Energy monitoring system

How Does a Solar Battery System Work?

During daylight hours, solar panels generate electricity from sunlight.

The energy produced is used in the following order:

Step 1 – Solar Panels Generate Electricity

Solar energy is first used to power appliances, equipment, lighting, and other electrical loads within the property.

Step 2 – Power Your Home First

If the solar panels generate more electricity than is being consumed, the excess energy is stored in the battery for later use.

Step 3 – Store Excess Energy

Depending on system settings and regulations, any remaining surplus energy may be exported to the electricity grid.

Step 4 – Use Stored Power Later

When solar production decreases, such as during the evening, cloudy weather, or at night, the battery supplies stored electricity to the property.

This reduces the need to purchase electricity from the grid.

What Happens During a Blackout?

One of the biggest advantages of installing battery storage is having backup power during a blackout.

Most standard grid-tied solar systems automatically shut down during a power outage for safety reasons. However, a properly configured solar + battery system can continue supplying electricity to selected essential circuits during a blackout.

This can help keep critical equipment running, including:

Lighting
Refrigerators
Internet routers
Security systems
Medical equipment
Business-critical operations

The amount of backup time depends on battery capacity and electricity usage.

What Are the Benefits of a Solar Battery System?

Lower Electricity Bills

By storing excess solar energy and using it later, you can reduce your reliance on grid electricity and increase overall savings.

Greater Energy Independence

Battery storage allows you to consume more of the solar energy you generate, reducing dependence on utility providers.

Protection Against Power Outages

Backup power capability provides peace of mind during unexpected blackouts or grid disruptions.

Better Energy Management

A battery system helps optimise energy usage by storing power when generation is high and releasing it when needed.

Support Sustainability Goals

Using more self-generated renewable energy helps reduce carbon emissions and supports environmental sustainability initiatives.

Is a Solar + Battery System Worth It?

A solar + battery system may be a worthwhile investment if:

Your area experiences frequent power outages.
You want greater energy independence.
You have high electricity consumption during evenings.
You operate critical equipment that requires uninterrupted power.
You are looking for long-term energy security.

While batteries increase the initial investment cost, they provide additional benefits that standard solar systems alone cannot offer.

Solar Battery System FAQs

Q: What is battery storage in a solar energy system?

A: It combines solar panels with a battery storage unit, so instead of sending all surplus electricity back to the grid, excess solar energy is stored and used later when solar production is low or when demand increases.

Q: What equipment is included in a solar battery installation?

A: A typical setup includes solar panels, a hybrid inverter, a battery storage unit, and a monitoring and energy management system that work together to create a more flexible and resilient energy solution.

Q: How is the electricity produced by the panels actually used?

A: During daylight hours, solar energy is used in order: first to power the property's appliances and equipment, then to charge the battery with any excess, and finally any remaining surplus may be exported to the grid depending on system settings and regulations.

Q: Why should I add battery storage to my existing solar panels?

A: A battery lets you store excess solar energy generated during the day and use it later, such as at night or during high-demand periods, giving greater energy independence and security compared to a solar-only system.

Q: Is the NEM scheme still relevant for a new solar + battery system?

A: No. NEM (Net Energy Metering) officially ended on 30 June 2025 and is no longer accepting new registrations; it has been replaced by Solar ATAP (Solar Accelerated Transition Action Programme), effective 1 January 2026, which offers cash rebates of up to RM3,000 through SuRIA Home.
