Factors that affect the cost of solar systems in Queensland?

Many factors can affect the cost of solar systems in Queensland as they may reduce or increase the cost of a solar system for different reasons.

The System size

The larger the solar system, the more solar panels and other equipment is required, which can increase the cost. However, the larger the solar system is, the more electricity it produces which, in turn, allows households to save more on energy costs.

The Type of solar panels

There are different types of solar panels, such as monocrystalline, polycrystalline, and thin-film and the cost varies depending on the materials used to manufacture the solar panels. These different materials have different levels of efficiency, durability, and lifespan and the better these qualities are, the costlier the solar panel will be.

The Brand of solar system

The cost of solar panels can vary depending on the brand and its reputation in the market. Popular brands usually have good customer reviews and are generally tested and trusted brands. This allows them to have a higher price point compared to less popular solar system brands.

STC rebate location

Queensland has three different rebate amounts depending on where you live in the state. STC zones 1, 2 and 3 intersect Queensland. Depending on your Postcode and subsequent zone, you could be entitled to a large government rebate.

Installation costs

The cost of installation can vary depending on the complexity of the installation, such as the type of roof, mounting system, and wiring required. Some rooftops cause installers more difficulty when installing solar panels and more complications with wiring and this can increase the cost of a solar system.
