How Much Power Does a Single Solar Panel Generate in Victoria?

 Across Melbourne and regional Victoria, more households are switching to solar to save on power bills and cut down on emissions. One of the most common questions we get asked is: “How much energy does one solar panel actually produce?”

Let’s break it down.

Average Output from One Solar Panel

Most solar panels installed on Victorian homes today have a capacity of 300–400 watts. Under good conditions, each panel can produce:

  • 1.2–1.6 kWh of electricity per day

  • Around 35–45 kWh per month

  • Between 500–650 kWh per year

For example:

  • A 370W panel produces about 1.4–1.5 kWh daily.

  • A 440W panel can generate 1.7–1.8 kWh daily.

What Affects Solar Panel Output?

The amount of electricity you’ll get from your solar panels depends on several factors, including:

  • Sunlight Hours – Melbourne averages 3.8–4.2 peak sun hours per day.

  • Panel Orientation & Tilt – North-facing with a tilt of ~37° is ideal.

  • Shading – Trees, chimneys, or nearby buildings can reduce output.

  • Weather – Cloudy days produce less energy than sunny ones.

  • Panel Quality – High-efficiency panels capture more power in the same space.

How Many Panels Does a Home Need?

The average Melbourne household uses around 15–20 kWh per day.

  • A 6.6kW solar system (16–18 panels) generates ~24 kWh per day – enough for most families.

  • A 10kW system (24–27 panels) can generate 36–40 kWh per day – ideal for large households, batteries, and EV charging.

Getting the Best from Your Solar

To make sure your solar system performs at its peak:

  • Install panels in full sun with no shading.

  • Keep panels clean to avoid dust and dirt build-up.

  • Invest in a quality inverter for efficient energy conversion.

  • Monitor your daily production to spot issues early.

  • Add a battery to store excess energy for night use.

Why Solar Is a Smart Choice

Solar panels use the photovoltaic effect to turn sunlight into electricity. By investing in solar, you lower your bills, reduce your reliance on the grid, and contribute to a cleaner environment for Victoria.

Final Thoughts

In Victoria, a single solar panel typically produces between 1.2–1.8 kWh of energy per day. While one panel won’t power an entire home, a full system of 10–20 panels can significantly reduce or even eliminate your energy costs.
