Solar racking system is a crucial component in the installation of solar energy system, which provides safe and stable support for PV panels and ensures the efficiency and reliability of solar PV power generation. When choosing the right mounting method, we also need to consider the cost factors of different systems. Solar ground systems and rooftop systems are the two most common types of installation today. The installation costs of these two systems will be compared below.

installation process

The installation of solar ground systems involves a number of aspects such as land preparation, foundation construction and racking installation. It requires land clearing and leveling, a longer construction period, and additional investment in materials and labor costs. Solar roof system, on the other hand, are relatively easy to install and are mounted directly on the roof without land preparation and infrastructure, and the installation time is usually shorter.

Material costs

Solar ground systems require more materials such as racking systems, solar cables, and fixtures. Solar mounting system are more costly and require the use of specially designed racking systems. Rooftop systems, on the other hand, are relatively simple to install and reduce some of the material costs.

Power density

Solar ground systems can arrange PV modules in a larger spatial area and utilize a larger area to absorb solar energy, thus having a higher power density. Solar roof system, on the other hand, have a relatively low power density due to the limitations of the roof area.

Maintenance costs

Ground-mounted solar systems are easier to maintain and clean than rooftop systems, eliminating the need to climb the roof and making it easier to inspect and repair. Rooftop systems, on the other hand, are more difficult to maintain and clean and require additional safety measures and labor costs.

To summarize, both solar ground system and rooftop system have their own advantages and adaptable scenarios. Ground-mounted systems are suitable for places that require more flexible installation positions and angles, but their construction costs are higher. Rooftop systems are suitable for existing buildings and are less expensive.

However, installation cost comparisons are also influenced by factors such as geographic location, system size, material selection, and local market conditions. Installation projects may vary by region and by size. For large-scale solar power projects, ground-mounted systems may be more advantageous. For buildings with large roof areas, rooftop systems are the more economical choice. Therefore, before choosing a solar power system, it is advisable to conduct detailed cost estimates and comparisons to determine the most suitable option for your situation.
