Asking “how much do solar panels cost?” is a lot is like asking “how much does a car cost?”. It’s really tough to provide a direct answer with a single amount, without taking into account various elements. Similarly to how there are a variety of factors that go into determining the costs of a car (make, model, features etc.), there is a myriad of components that work together to determine how much do solar panels cost in Australia. We’ve broken down the main ones including the solar panels themselves, the size of solar panel system and the type of solar panel technology that you plan on installing.

Solar Panel Technologies

A common misconception with solar is that people think that the number of solar panels is one of the biggest determining factors. In reality, it’s the type of solar panel that you choose; not necessarily how many are required. The electricity output of your solar panel system will not be determined by how many panels you need; moreover, it’s about the overall capacity of the system. For example, your solar panel system may have 20 x 250W panels, or 25 x 200W panels – either way, you end up with a 5KW solar system.

In saying that, it’s the quality of these panels that determine the energy output. One of the biggest determining factors for the question of “how much does solar cost?” is the solar panels themselves. Another important element to keep in mind when considering solar panel prices Australia is that properties may require additional solar technology such as inverters and solar batteries.

When comparing solar panel prices Australia and the output from each type of panel, three of the major technologies include Monocrystalline, Polycrystalline and Thin Film solar panels.

At Captain Green, we only supply the highest quality, most efficient panels and solar technology on the market. We generally work with Monocrystalline, which is not typically the cheapest type of solar panel; however, it is the most efficient and highest watt solution. We work with several high quality Australian solar panel brands to deliver the most efficient, effective and exceptional solar panel installation. Some of the solar power brands that we operate with include Jinko, Q Cells, LG Solar and Aleo.

The Size of Solar System

The solar system size that you require for your property will also be one of the main determining factors for how much do solar panels cost. You can work out the solar panel system size that your property requires by looking at your latest energy bills. Essentially, you need to have an understanding of the amount of energy you plan on generating to determine which solar panels and how much will solar panels cost for your property.

The capacity of the solar panel in Watts will be a direct cost determining factor, as solar panels and solar packages are generally priced depending on the output per watt. The Watts of each solar panel relates to the amount of electricity generated in normal conditions. For example, a 10W panel installed and operating in ideal conditions will generate ten watt-hours of electricity each hour. Multiple 10W panels can be used to generate higher wattage per hour, creating a solar panel system.

How much does solar cost for a typical household? On average, a typical residential property uses approximately 20kWh of energy a day. A 5kW solar system would typically meet the daytime power requirements of such a home. However, the right solar system size will come down to how much power you plan on generating and the unique needs of your property.
