How should Solar Panels be Installed?

Looking to switch to solar power? Installing solar panels is an exciting endeavour that allows homeowners to harness the power of the sun and reduce their reliance on traditional and unsustainable energy sources. However, it is crucial to ensure the proper installation of solar panels to maximise their performance, longevity, and safety. This post will provide a guide on how solar panels should be installed, offering important insights for a successful and efficient process.

The popular location for solar panel installation is the roof so that panels gain the maximum sunlight. However, if this is not appropriate or desired, solar panels can also be mounted directly on the ground. This relies on nothing blocking sunlight access. 


1: Site Assessment and Planning:

Before installing solar panels, a thorough site assessment needs to be conducted to determine the ideal location of the panels on your property. Factors such as roof orientation, shading, and structural integrity should be considered. Additionally, any necessary permits or approvals should be obtained that are required by local authorities.

2: Mounting System Installation:

Begin by installing the mounting system that will secure the solar panels to the roof or ground. The mounting system should be structurally sound, weather-resistant, and compatible with the chosen solar panel type. The mounting structure must be tilted at an angle of between 18-36 degrees to ensure maximum sunlight exposure. Follow the manufacturer's instructions carefully. 

3: Electrical Wiring and Connections:

Next, carefully wire the solar panels to connect them in a series or parallel configuration, depending on the system design. Typically, MC4 connectors are used as they are suitable for all solar panels. The electricity supply should be shut off during this wiring stage. Consult a licensed electrician to ensure compliance with local electrical codes and safety standards. Properly route and secure the wiring to avoid any damage or exposure.

4: Panel Installation:

With the mounting system in place and electrical connections ready, it's time to install the solar panels. Place each panel onto the mounting brackets, ensuring a secure fit. Use appropriate mounting hardware and follow the manufacturer's guidelines for a secure fit and the correct torque specifications to prevent any damage.

5: Inverter Installation:

Install the inverter, which converts the direct current (DC) produced by the solar panels into usable alternating current (AC) for your home's electrical system. The inverter should be installed in a well-ventilated area and connected to the main electrical panel following safety protocols. Inverters are usually more efficient if kept in a colder location. If your inverter is outdoors, ensure it is not impacted by the afternoon sun. Alternatively, if the inverter is installed indoors, a utility room or garage are great locations as they have good ventilation and stay cool for most of the year. 

6: Monitoring and Safety Measures:

Set up a monitoring system to track the performance and efficiency of your solar panels. This allows you to monitor energy production and identify any problems quickly. Additionally, implement necessary safety measures, such as labelling DC disconnect switches and ensuring proper grounding for the solar power system.

7: Final Inspections and Testing:

Before activating your solar system, schedule a final inspection with the relevant authorities or a certified professional. This process ensures that the installation complies with safety standards and regulations. Conduct comprehensive testing to verify proper functionality and address any potential issues.


Proper installation is essential for maximising the benefits of solar panels. By following a systematic approach, you can ensure a successful and efficient installation. Remember to consult professionals when needed, such as licensed electricians or certified installers, to guarantee compliance with local codes and safety standards. With careful planning and attention to detail, your solar panels will provide clean, sustainable energy for years to come, reducing your environmental impact and generating long-term savings
