What Do Solar Batteries Look Like – and Where Can I Install Them?

Adding a battery to your solar setup is one of the best ways to get more value from your system. Before you start, it’s important to know what batteries look like. You should also learn where they go. Finally, make sure your installation follows safety and rebate rules.

Spoiler alert: Today's batteries are sleek, small, and smarter than before. With the federal Cheaper Home Batteries rebate, you can save 30% off the cost. This makes them easier to get, too.

What Does a Solar Battery Look Like?

Forget bulky metal boxes or warehouse-style gear. Modern solar batteries are designed with residential homes in mind. Most are wall-mounted units. They are about the size of a bar fridge or air conditioner. They have simple, minimalist designs in neutral colors.

Typical battery design features:

• Height: 70–120cm

• Width: 50–75cm

• Depth: 15–30cm

• Weight: 70–120kg

• Appearance: Sleek and unobtrusive in grey, black or white

Popular brands like Tesla Powerwall, Sigenergy, and AlphaESS all feature modern designs that suit indoor or outdoor installation.

Where Can Solar Batteries Be Installed?

Most batteries are designed to be installed:

• In garages (on a wall with bollards if a car is present)

• Under eaves or in a shaded outdoor area

• Inside utility rooms, if ventilation and safety requirements are met

• In sheds or standalone battery cabinets, where compliant

The ideal location is out of direct sunlight and extreme temperatures. Batteries prefer stable environments, usually between 15–30°C, for best performance and longevity.

💡 Tip: If you’re low on space, ultra-slimline models like the Anker battery are a good fit for tighter garage areas.

What Are the Rules Around Installation?

To get rebates, you need to meet certain rules. This includes the 30% federal subsidy and the NSW VPP-linked rebate. Your battery installation must follow safety and compliance guidelines.

Key requirements:

At Shoalhaven Solar, we handle site assessment, installation, and rebate paperwork to ensure your battery ticks every box.

Can I Install a Battery Outdoors?

Yes — most modern batteries are weather-rated (IP65 or higher), meaning they’re rainproof and can be installed outside. However, we strongly recommend:

• Avoiding direct sunlight

• Installing under eaves or a battery enclosure

• Choosing shaded areas to maintain optimal temperature

Temperature extremes (hot summers, cold winter nights) can impact battery efficiency, reducing charge/discharge rates and shortening lifespan.

What About Battery Size and Clearance?

Clearance and dimensions matter, especially in garages or tight utility rooms.

For example:

Want to park your car safely in the garage after installation? We’ll make sure the battery doesn’t get in the way — and add compliant bollards if needed.

Can Batteries Go in Sheds or Outbuildings?

Yes, but it depends on a few things:

• Distance to your main switchboard (must be within allowable range)

• Structural suitability and ventilation

• Protection from water ingress and pests

• Fire safety (some sheds may need fire-rated walls or separation)

Shoalhaven Solar often installs batteries in sheds, farm buildings, and special enclosures. We will check your site and tell you the best option.

What If I Want to Expand Later?

Planning to go off-grid one day, or add an electric vehicle? Some batteries are modular, meaning you can add capacity in stages. For example:

• Sigenergy SigenStor allows additional 5–8 kWh blocks to be added later

• AlphaESS and Tesla generally require adding a full second unit

If future-proofing is important, we’ll guide you to a battery that grows with your needs.

Will This Help Me Get the Rebate?

Absolutely — but only if your installation complies with the program rules. The federal 30% battery discount and NSW rebates both require:

• Clean Energy Council approved installers and products

• An installation that complies with safety and wiring regulations

• Physical space and clearance that meet the battery’s specifications

We’ll make sure it’s done right — from wall strength to spacing to ventilation.
