Among them, solar modules and inverters account for about 40% of total installation cost, and there are some differences depending on the crystal structure of the solar module, but most of them are generally used by existing maker products.

In addition, the inverter occupies about 10% of the installation cost, and it is common to purchase and use a general commercial product.

On the other hand, the supporting structure for fixing and supporting the solar module is largely different according to the area where the solar power plant is installed, the topography, the construction ability of the construction company, the durability and safety of the structure.

In other words, major components such as solar modules and inverters can be installed by selecting existing mass production products that have already been verified. However, since the solar module supporting structure is used for at least 30 years once installed, it is safe and durable Is very important.

Therefore, it is necessary to reduce the cost of the solar module supporting structure, which is installed in various forms for each construction company, taking the most cost in installing the solar power plant.

Particularly, the portion that occupies the highest portion in the installation of the PV module holding structure includes the raw material cost of the supporting structure and the labor cost of the worker who installs it, so that the shortening of the construction period of the PV power plant is the most expensive This is a way to save money.
