Site Assessment
When it comes to solar panel installation, the first step is to assess the suitability of a property for solar energy. This involves evaluating a number of factors that can affect the performance and efficiency of a solar panel system. Some of the key factors to consider when assessing the suitability of a property for solar panel installation include:
- Roof type: The type of roof on a property can impact the feasibility and ease of solar panel installation. Sloped roofs are generally the best candidates for solar panel installation, as they provide a larger surface area and are easier to work on. However, it is still possible to install solar panels on pitched roofs, as long as they are in good condition and not shaded by trees or other structures. Most roofs in Australia are pitched at around 15 degree or 22.5 degree angle.
- Orientation: The orientation of a roof can also affect the performance of solar panels. North-facing roofs are generally the best choice for solar panel installation, as they receive the most direct sunlight throughout the day. East- and west-facing roofs can also work, although they may receive less direct sunlight and therefore produce less energy.
- Shading: Solar panels require direct sunlight to function effectively, so it is important to assess the shading on a property. Trees, buildings, and other structures can all cast shadows on a roof and reduce the amount of sunlight that reaches the solar panels. It is generally best to install solar panels on a roof with minimal shading, or to trim back any trees or other structures that may be causing shading.
In addition to these factors, it is also important to consider the overall condition of a roof when assessing its suitability for solar panel installation. A roof that is in poor condition or approaching the end of its lifespan may not be able to support the weight of solar panels, and may need to be repaired or replaced before installation can proceed.
Designing A Solar Panel System
Once the suitability of a property for solar panel installation has been assessed, the next step is to design the solar panel system. This involves determining the size and layout of the panels, as well as choosing the right panel type and equipment.
- Determining the size and layout of the panels: The size and layout of the solar panel system should be based on the energy needs of the property, as well as the available space on the roof or other installation site. A professional solar panel installer will be able to assess your energy needs and recommend the appropriate size and layout for your solar panel system. It is generally best to install as many panels as possible, within the constraints of the available space and budget.
- Choosing the right panel type and equipment: There are several different types of solar panels available on the market, and it is important to choose the right one for your needs. The most common types of solar panels are monocrystalline, polycrystalline, and thin-film. Monocrystalline panels are the most efficient, but also the most expensive. Polycrystalline panels are less efficient, but also less expensive. In addition to the panels themselves, there are also a number of other pieces of equipment that are required for a solar panel system, including solar inverters, and mounting hardware. A professional solar panel installer will be able to recommend the best equipment for your specific needs.

Permitting And Approvals
Obtaining the necessary permits and approvals is an important step in the solar panel installation process. Depending on your location, there maybe several different permits and approvals required in order to install solar panels on your property. These permits and approvals ensure that the solar panel installation meets all local building codes and regulations, and is safe for both the property owner and the general public.
In Perth, the permitting process for residential and commercial solar panel installation is relatively straightforward depending on what system size you are willing to install. Some large commercial projects may need to obtain building permits and go through a structural check which is done by an engineer who will confirm and approve that the building structure is strong enough and safe for the installation but in most cases, the first step is to inform/apply for an approval from your electricity retailer and then Western power for technical approval.
Preparing For Installation
Once the permitting and approvals process is complete, the next step in the solar panel installation process is preparing for the actual installation. This involves ordering the necessary materials and scheduling the installation date, as well as completing any necessary pre-installation inspections and tasks.
- Ordering materials and scheduling the installation date: The process of ordering materials and scheduling the installation date will depend on the specific solar panel system that you are installing, as well as the availability of the solar panel installer. It is generally best to work with a professional solar panel installer who can help you order the necessary materials and schedule the installation date based on your needs and preferences. It is also important to confirm that all necessary permits and approvals are in place before proceeding with the installation.
- Pre-installation inspections and tasks: There are several inspections and tasks that should be completed before the actual installation begins. These may include an inspection of the roof or other installation site to ensure that it is in good condition and ready for the solar panels. Other pre-installation tasks may include cleaning the roof or installation site and securing any necessary financing.
Preparing for solar panel installation requires careful planning and coordination. By completing the necessary inspections and tasks and ordering the necessary materials, you can ensure that the installation process goes smoothly and efficiently.
The Installation Process
Once all the necessary preparations have been made, the next step in the solar panel installation process is the actual installation of the panels. This involves placing and mounting the panels on the roof or other installation site, and connecting them to the electrical grid.
- Placing and mounting the panels: The process of placing and mounting the panels will depend on the specific solar panel system and installation site. Generally, the panels are mounted on brackets or racks that are attached to the roof or ground. The panels should be placed in a location that receives the most direct sunlight and should be properly aligned with the sun to maximise their performance. It is important to follow the manufacturer’s instructions for mounting the panels, and to use the appropriate tools and equipment to ensure that the panels are secure and stable.
- Connecting the panels to the electrical grid: Once the panels are in place, the next step is to connect them to the electrical grid. This involves installing an inverter, which converts the direct current (DC) electricity produced by the panels into alternating current (AC) electricity, which can be used in the home or business. The inverter is usually mounted on the wall of the home or business, and the panels are wired to the inverter using electrical conduits. The inverter is then connected to the electrical panel, which distributes the electricity throughout the property. It is important to follow all necessary safety guidelines and codes when connecting the panels to the electrical grid, and to work with a professional solar panel installer who has the necessary expertise and experience.
The installation process for solar panels requires careful attention to detail and a thorough understanding of electrical systems and installation techniques.
Testing and Commissioning
Testing and commissioning involves a number of different checks and inspections, including visual inspections of the panels and equipment, as well as electrical tests to ensure that the system is producing the expected amount of electricity.
During the testing and commissioning process, it is important to ensure that all necessary safety guidelines and codes are followed, and to work with a professional solar panel installer who has the necessary expertise and experience. The testing and commissioning process is typically completed by a third-party inspector or by the local utility company, who will issue a final approval once all necessary checks have been completed.
Once the solar panel system has been tested and commissioned, and final approval has been received, the system can be turned on and put into operation. This typically involves flipping a switch or activating the system through the inverter. Once the system is on, it should begin producing electricity immediately, and can be monitored using a monitoring system or app to ensure that it is performing optimally.
Ongoing Maintenance and Monitoring
Once a solar panel system is installed and operational, it is important to perform regular maintenance and monitoring to ensure that it continues to function optimally. Solar panel systems require minimal maintenance, but there are a few key steps that should be taken to ensure their longevity and performance.
One of the most important things to do is to keep the panels clean. Dust, dirt, and debris can accumulate on the panels over time, which can reduce their efficiency. Cleaning the panels regularly, either by hand or with a pressure washer, can help maintain their performance. It is also important to check the panels for any signs of damage or wear, and to have them repaired or replaced if necessary.
Another key aspect of solar panel maintenance is monitoring the system to ensure that it is performing as expected. Most solar panel systems come with a monitoring system or app that allows you to track the production of electricity in real-time, and to identify any potential issues or problems. By regularly checking the monitoring system and addressing any issues that arise, you can ensure that your solar panel system continues to operate efficiently and effectively.
Solar panel installation is a complex process that requires a thorough understanding of site assessment, design, permitting, and installation techniques. By working with a professional solar panel installer, such as Vista Electrical Controls, you can ensure that your solar panel system is designed and installed correctly and will provide long-term benefits for your property.
