How to Choose the Right Solar Setup for Your WA Home
With solar becoming more popular than ever in Western Australia — and the new $5,000 battery rebate now available — many homeowners are wondering:
Should I get a battery, or just install a bigger solar system?
It’s a good question, and the answer depends on your energy habits, budget, and long-term goals. At Solar You, we design every system to suit real WA households, so here’s a simple breakdown to help you decide what’s right for you.
Option 1: A Bigger Solar System – More Panels, More Daytime Power
A larger solar system means more panels on your roof, generating more electricity during the day. This can help you:
- Cover more of your daytime usage
- Run energy-hungry appliances like air con, pool pumps, or washing machines
- Export more power to the grid (and earn feed-in credits)
- Prepare for future upgrades like batteries or EV chargers
This is a great option if you’re at home during the day or can shift your energy usage to daylight hours.
✅ Best for:
Homes with high daytime usage, people working from home, or those wanting lower upfront costs and fast payback.
Option 2: Add a Battery – Store Power for Night-Time Use
A solar battery stores any extra power your system generates during the day so you can use it in the evening – when energy prices are usually highest.
With the new WA Government battery rebate (up to $5,000), batteries are now far more accessible for many homeowners. Adding one can:
- Maximise your solar savings
- Reduce reliance on the grid
- Protect against blackouts
- Future-proof your home for rising energy costs and EV charging
✅ Best for:
Households using most power in the evening, people looking for energy independence, or those wanting blackout protection.
So, Which Option Is Right for You?
| Scenario | Bigger System | Add Battery |
|---|---|---|
| You’re home during the day | ✅ | Maybe |
| You’re out during the day and use power mostly at night | Maybe | ✅ |
| You want the lowest upfront cost | ✅ | Maybe |
| You want blackout protection | ❌ | ✅ |
| You want to maximise long-term savings | ✅ | ✅ |
| You want to take advantage of the WA battery rebate | ❌ | ✅ |
