Small Business                   20kW – 50kW

Medium Business              50kW – 100kW

Warehouse                         100kW – 250kW

Manufacturing Facility     250kW – 1MW+

Large Industrial Site          1MW+


The electricity generated can be:

  • Consumed directly by the business
  • Exported to the electricity grid
  • Stored in batteries for later use

At GES Energy, we design systems that maximise self-consumption and minimise electricity purchases from the grid.

 

Why Commercial Solar Makes Financial Sense

Most businesses consume the majority of their electricity during daylight hours—exactly when solar panels are generating power.


This natural alignment allows businesses to significantly reduce electricity purchases from their retailer.


For example:

A warehouse operating during business hours can offset lighting, air conditioning, machinery, and equipment loads using solar energy.


A manufacturing facility can reduce peak demand charges and lower overall operating expenses.


Many Victorian businesses are currently achieving annual savings of:

  • $5,000 to $20,000 per year for smaller systems
  • $20,000 to $100,000+ per year for larger commercial installations


The exact savings depend on energy usage patterns, tariff structure, solar system size, and battery storage integration.

 

Victorian Government Commercial Solar Rebates

Victorian Energy Upgrades (VEU) Program

The Victorian Energy Upgrades (VEU) Program provides valuable financial incentives for eligible businesses installing commercial solar systems.

Solar energy can be a smart way to generate electricity for your home or business. However, solar panels only produce energy when sunlight is available. This means you may still need electricity from the grid during the evening or when solar production is low. Battery storage provides a way to store energy for later use. A Deye inverter and battery storage system can work with solar panels to manage energy production, storage, and household or business consumption. Deye offers residential hybrid inverter and energy storage solutions designed for different system sizes and applications. For property owners looking for Deye Inverter & Battery Storage in Greater Victoria , GES Energy can help with system design, product selection, and professional installation. The right solution depends on your electricity usage, existing solar system, property requirements, and energy goals. What Is a Deye Hybrid Inverter? A hybrid inverter is an important part of a solar and battery storage system. It helps manage electricity from your solar panels, battery, home, and the grid. This allows energy to be used where it is needed and stored when appropriate. Deye offers a range of residential hybrid inverters for different applications. Its Australian residential range includes single-phase and three-phase models with different power capacities and battery configurations. This flexibility can make Deye suitable for a range of homes and energy requirements. However, the correct inverter should always be selected based on the property's electrical system and expected energy demand. How Does Deye Battery Storage Work? The process is straightforward. During the day, your solar panels generate electricity. Your home or business can use that electricity immediately. If your solar system produces more energy than you need at that time, compatible battery storage can store some of the excess energy. You can then use the stored energy later. This can be particularly useful when solar production falls in the evening or during periods when your electricity demand is higher. Deye's current home energy storage systems combine battery storage, hybrid inverter technology, and energy management features. Some Deye systems are also designed to provide backup power to connected loads during a grid outage. Why Consider Battery Storage in Greater Victoria? Energy consumption does not always match solar production. Your solar panels may generate their highest output during the middle of the day, while your household may use more electricity in the morning and evening. Battery storage can help close this gap. Instead of using all your solar electricity immediately or exporting excess energy, you can store some of it and use it later. GES Energy explains that solar batteries can store solar energy for later use and help property owners make greater use of their solar generation. The company provides battery storage design and installation services across Victoria. Store More of Your Solar Energy One of the main reasons people consider battery storage is to make better use of their solar power. A solar system can produce more electricity than your property needs at certain times of the day. A compatible battery can store some of that excess energy. You can then use the stored energy when your solar panels are producing less electricity. This can create a more flexible energy system. Instead of relying only on the timing of solar production, you have the option to use stored energy when it suits your needs. Battery Storage for Backup Power Power outages can interrupt important household and business activities. Depending on the system design, a battery storage system can provide backup power to selected loads when the grid goes down. Deye's current residential energy storage range includes systems with backup support for connected loads. The amount of power available during an outage depends on the selected equipment, battery capacity, electrical configuration, and the loads connected to the backup system. For this reason, backup requirements should be discussed during the design stage. You may want to keep essential lighting, refrigeration, communications, or other important equipment operating during an outage. Deye Inverter and Battery Storage for Existing Solar Systems You do not necessarily need to install a completely new solar system to consider battery storage. In some situations, battery storage can be added to an existing solar installation. However, compatibility must be checked first. Your existing inverter, solar array, electrical system, and proposed battery need to work together correctly. A professional assessment can identify the most suitable approach. GES Energy provides solar battery solutions for Victorian homes and businesses and can assess your existing energy setup before recommending a storage solution. Choosing the Right Battery Size Battery capacity is normally measured in kilowatt-hours, or kWh. The capacity you need depends on how much electricity your property uses and how you want to use the battery. A household that mainly wants to store excess solar energy may have different requirements from a household that wants significant backup capacity. Businesses can also have different requirements because their electricity demand may be higher or concentrated at particular times. Deye offers scalable storage solutions. For example, its current All-In-One Home ESS range can be configured with different inverter power levels and expandable battery capacity. The right size should be determined from your actual energy usage rather than simply choosing the largest available battery. Deye Battery Storage for Homes Every home has a different electricity profile. Some homes use most of their electricity during the day, while others have higher demand in the evening. A battery can help shift stored solar energy to the times when it is needed. This can make your solar system more useful throughout the day. For homeowners in Greater Victoria, a professional energy assessment can help determine whether battery storage is suitable and what system configuration may work best. Deye Battery Storage for Businesses Businesses can also benefit from energy storage. Commercial properties often have larger electricity loads and may use significant amounts of energy during operating hours. Battery storage can provide another way to manage energy generated by a commercial solar system. Depending on the system design, stored energy can be used when required, while smart energy management can help coordinate solar generation, battery charging, and electricity consumption. Deye also provides energy storage solutions for commercial and industrial applications, with different system configurations available for different energy requirements. Smart Energy Management Modern battery systems do more than simply store electricity. Energy management is an important part of understanding how your solar and battery system operates. Deye's current residential energy storage systems include energy management and monitoring features. Depending on the selected system, users can monitor energy production, consumption, battery status, and other system information. Monitoring can help you understand how much energy your solar panels are producing and how your battery is being used. This information can also help you make better decisions about your household energy consumption. Why Professional Installation Matters Battery storage is a significant electrical installation. It needs to be designed and installed correctly for safe and reliable operation. Energy Safe Victoria notes that battery energy storage systems have important safety requirements and that installations should meet applicable regulations and standards. It also highlights the need to assess switchboards when adding battery systems or other supplementary supplies. Professional installation is therefore an important part of the process. A qualified installer can assess the property, review the electrical system, determine suitable equipment, and configure the system according to the installation requirements. Why Choose GES Energy? Choosing the right battery is only one part of a successful energy storage project. The design and installation are equally important. GES Energy provides solar battery design and installation services for residential and commercial customers across Victoria. The company states that its Victorian battery installers are accredited by Solar Accreditation Australia and that it provides a five-year workmanship guarantee on its solar power projects. GES Energy can help you understand your available options and determine whether a Deye inverter and battery system is appropriate for your property. A Complete Approach to Solar and Battery Storage A good energy storage system should be designed around your property. Your electricity consumption, solar generation, backup requirements, available space, and future energy needs should all be considered. Deye offers different inverter and battery configurations, including single-phase and three-phase options. This allows the system to be selected according to the property's requirements rather than using one standard solution for every customer. GES Energy can assess these factors before recommending a system. This helps ensure that the inverter and battery are appropriate for your existing or planned solar installation. Is Deye Inverter & Battery Storage Right for You? Deye inverter and battery storage may be worth considering if you already have solar panels or are planning a new solar system. It can also be an option if you want to store excess solar energy, increase your use of stored energy, or explore backup power. However, the best system depends on your property. Your electricity consumption and solar generation should be reviewed before selecting equipment. A professional assessment can help you understand the available options and avoid choosing a system that does not match your actual requirements.
