Solar systems are one of the most common mediums used in Australia to save energy and reduce electricity bills. Figures show 31.46% of Australians invest in buying solar panels for their homes, and the number is only expected to rise.

However, since installing a solar panel system is a long-term investment, it is crucial to make well-informed decisions during the installation process to minimise expenses. Avoiding mistakes at the outset ensures that costs are saved, and resources are utilised optimally.

In this blog, we will cover the common mistakes that homeowners make when deciding to buy solar panels. This guide will help you make informed decisions and save money in the long run.

Mistake #1: Inadequate Research Before Buying Solar

Proper planning and extensive research are crucial for homeowners to avoid mistakes during solar panel installation. Therefore, it is essential to understand the unique installation requirements for your house before embarking on this process.

One common mistake is focusing only on present needs while disregarding potential long-term changes. Therefore, you must ensure that your solar panel design and placement allow for future expansion. For example, if the entire roof is covered with solar panels, it is important to consider where additional panels could be added if needed.

Another aspect that requires careful consideration is installing the battery and inverter, as not all of them can handle the power generated by solar panels. Therefore, it is important to select the appropriate battery and inverter that allow for future expansion of the solar panel system.

Additionally, you must ensure that the non-productive components of your solar panel face away from the sun. This prevents the corrosion of the panels, as current-carrying apparatuses are safely installed.

You must also be mindful of the wind, as it can cause wire loops to oscillate, resulting in heightened noise levels and the risk of electrical sparks.

Mistake# 2: Overlooking System Size Requirements

One of the main solar mistakes homeowners when buying solar is overlooking the importance of system size requirements. It is crucial to assess the energy needs of the household accurately. This ensures that the solar system’s size aligns with those requirements.

Installing a system that is too small may result in insufficient energy generation, leaving the homeowners reliant on grid power. This can defeat the purpose of installing a solar panel system.

Conversely, opting for an excessively large system can lead to unnecessary costs and wasted energy production. Proper consideration and consultation with solar experts are essential to determine the optimal system size for your household’s energy needs.

Moreover, it is critical to install a solar panel system that meets Australian Government Solar System Standards. This ensures your system performs optimally throughout its lifetime.

Mistake #3: Failing to Consider the Climate

Another mistake to avoid when installing solar panel systems is not being aware of the climate conditions specific to your location. Understanding how the climate can impact the efficiency and performance of your solar panels is crucial. For example, let’s consider the climate in Perth, Australia. Perth has a Mediterranean climate with hot and dry summers, mild winters, and abundant sunshine throughout the year.

This means that solar panels in Perth can receive ample sunlight, which is ideal for generating solar energy. However, the hot temperatures during summers can lead to increased heat and potential thermal issues for the panels. Therefore, homeowners in Perth need to consider factors such as panel placement, shading, and cooling mechanisms to ensure optimal performance and longevity of their solar panel system. Being aware of the specific climate conditions of your location will help you make informed decisions and maximise the benefits of solar power.

Mistake #4: Neglecting Installation Quality

One critical aspect that should not be neglected when installing solar panels is the quality of the installation itself. Neglecting installation quality can lead to various issues and compromise the solar panel system’s overall effectiveness and efficiency.

Experienced and certified professionals should carry out the installation process. Improper installation techniques or shortcuts can result in reduced energy production, potential safety hazards, and even damage to the panels.

Furthermore, the quality of materials used during installation should not be overlooked. High-quality mounting systems, connectors, and wiring are crucial for ensuring the durability and reliability of the solar panel system. Conversely, choosing subpar materials or cutting corners to save costs can lead to premature system failures, increased maintenance needs, and decreased performance over time.

Proper sealing and weatherproofing are also vital aspects of a quality installation. Inadequate sealing can result in water leaks, moisture damage, and corrosion, compromising the longevity and efficiency of the system.

Mistake #5: Failure to Balance Solar Power across Phases

Another common solar panel mistake is not balancing solar power across phases. In a three-phase electrical system, it is crucial to distribute solar power evenly across the phases.

Failure to balance the solar power can result in an imbalance of electricity flow and potential overload in one phase, while the other phases remain underutilised. This can lead to inefficiencies in the system and potential issues with electrical equipment and appliances.

To address this, it is important to consult a solar installer who can assess the electrical distribution. This individual can also design the system to distribute the solar power across the phases evenly. This can involve proper configuration of inverters and electrical wiring to ensure balanced power flow.
