5 Factors to Consider When Choosing a Solar PV Mounting System


Solar PV (photovoltaic) systems are a popular way to generate clean, renewable energy from the sun. However, to ensure the optimal performance and longevity of a solar system, a reliable and robust mounting system is needed. The mounting system holds the solar panels in place and positions them at the correct angle to capture the maximum amount of sunlight. When choosing a solar PV mounting system, there are several factors to consider. Here are the top 5:

  1. Type of surface: The type of surface the solar panels will be installed on will impact the choice of mounting system. For example, if the solar panels will be installed on a flat roof, a ballasted mounting system may be a good option. Ballasted systems use weights to keep the mounting structure in place, rather than penetrating the roof with bolts or screws. If the solar panels will be installed on the ground, a pile-driven system may be more appropriate, as it can be easily driven into the soil.

  2. Load-bearing capacity: The mounting system needs to be able to support the weight of the solar panels, as well as any additional load, such as snow or wind. The load-bearing capacity of the mounting system should be able to withstand the most extreme weather conditions in the installation area. For example, if the area is prone to heavy snow, the mounting system should be designed to withstand the weight of the snow.

  3. Orientation and tilt: The orientation and tilt of the solar panels are important factors to consider, as they impact the amount of sunlight the panels receive. In the Northern Hemisphere, solar panels should face south to receive the most sunlight, while in the Southern Hemisphere, they should face north. The tilt angle of the panels should also be adjusted based on the latitude of the installation site to ensure the panels receive optimal sunlight throughout the year.

  4. Materials: The materials used to construct the mounting system should be durable, weather-resistant, and able to withstand the weight of the solar panels. Common materials used in solar mounting systems include aluminum, steel, and concrete. The materials should be selected based on the specific needs of the installation site, such as the local climate and weather conditions.

  5. Installation and maintenance: The installation and maintenance of the solar PV mounting system should be done by qualified professionals. The installation process involves securing the mounting system to the roof or ground, connecting the panels to the mounting system, and wiring the system to the inverter and electrical grid. Proper maintenance is also important to ensure the longevity of the system and the safety of the people and property around it. The maintenance should include regular inspections of the mounting system and solar panels, as well as cleaning and repairs as needed.

In conclusion, choosing the right solar PV mounting system is crucial to the performance and longevity of a solar system. The type of surface, load-bearing capacity, orientation and tilt, materials, and installation and maintenance are all important factors to consider when choosing a mounting system. By taking the time to consider these factors and working with qualified professionals, a solar PV system can be installed safely and efficiently, providing clean and renewable energy for years to come.
