How Do Solar Panels Perform in Melbourne’s Weather?
If you’ve ever thought, “Can solar panels really work well in Melbourne’s unpredictable weather?”—you’re not alone. With our four-seasons-in-a-day climate, it’s a fair question. But here’s the thing: solar technology is far more resilient and efficient than most people realise.
In this post, we’ll break down exactly how solar panels perform in Melbourne’s weather, bust a few myths, and help you decide whether solar is the right move for your home. Spoiler: it probably is.
Oh, and if you’re serious about making the switch, Chris Ramsey at Ramselec Solar is your go-to local expert—more on him later.
☀️ Quick Answer: Do Solar Panels Work Well in Melbourne?
Yes, solar panels perform very well in Melbourne. Despite our cloudy days and chilly winters, Melbourne averages about 4.18 peak sun hours per day over the year, which is more than enough for efficient solar generation.
That means a quality solar system can power a typical home while slashing your energy bills—and still feed excess energy back into the grid.
🌦️ Melbourne’s Climate & Solar Potential
Melbourne is famous for its moody weather, but let’s look at the data:
Average sunny days/year: ~220
Average solar irradiance: ~4.18 kWh/m²/day
Annual rainfall: 650mm (fairly moderate)
Typical summer temps: 25–35°C
Winter temps: 6–14°C
This all translates into a solid solar yield—especially if your system is designed properly and installed by a pro (hi, Chris!).
🌤️ Do Solar Panels Work on Cloudy or Cold Days?
Absolutely. Modern solar panels are designed to capture diffused light, not just direct sun. So even on overcast days, they’ll still produce electricity—just at a reduced rate.
In fact, solar panels are often more efficient in cooler temperatures. Heat can decrease their performance, so Melbourne’s milder climate can actually be an advantage.
✅ Bonus tip: Clean, cool panels in winter can still generate solid output, especially when the sun does come out.
🧠 Common Solar Myths (Busted)
Let’s clear up a few myths that stop Melbournians from going solar:
❌ “Solar won’t work when it’s cloudy.”
Truth: It will. Light still reaches your panels, even if it’s filtered through clouds.
❌ “You need to live in Queensland for solar to be worth it.”
Nope. Melbourne’s solar uptake is growing rapidly for a reason—it makes economic and environmental sense here too.
❌ “Solar panels don’t work in winter.”
Actually, as long as there's daylight, they generate electricity. It’s about light, not heat.
⚡ Real Output: What You Can Expect in Melbourne
Here’s a rough guide based on average systems:
System Size Daily Output (kWh) Annual Output (kWh) 3kW 10–12 ~3,800–4,300 5kW 16–20 ~6,000–7,200 6.6kW 22–27 ~8,000–10,000
These numbers can vary based on roof orientation, shading, system quality, and installation.

🛠️ Getting the Most from Solar in Melbourne
Want to maximise your solar performance in Melbourne? Follow these tips:
1. Panel Positioning Matters
North-facing roofs are ideal, but east and west can still work very well depending on your usage patterns.
2. Minimise Shade
Trimming overhanging branches and avoiding tall nearby structures will improve efficiency.
3. Use Quality Panels & Inverters
Cheap panels might save money upfront but cost you long-term. Chris recommends Tier 1 brands with solid warranties.
4. Add a Battery (Optional)
Solar batteries let you store energy for evening use and blackout protection. Want to learn more? Check out Are Solar Batteries Worth It?.
