The ballast roof solar system refers to a solar energy system installed on the roof of an existing building. Compared to traditional installation methods, the ballast roof solar system has the following advantages:

1. Make full use of existing space: The ballast roof solar system utilizes the existing roof space of the building without occupying additional land or space. This is particularly advantageous for places with limited land resources or where ground installation is not possible.

2. Simplify the installation process: Due to its installation on the roof, the installation process of the ballast roof solar system is relatively simplified. Compared to building brackets and foundations on the ground, roof installation is usually faster and easier.

3. Reduce the energy cost of buildings: By installing solar energy systems on the roof, buildings can consume the generated solar power on their own, thereby reducing dependence on traditional power grids. This helps to reduce energy costs and provide more sustainable energy solutions.

4. Enhancing the value of buildings: The ballast roof solar system can add additional value to buildings. The existence of solar energy systems can not only reduce energy consumption and carbon footprint, but also improve the green certification and energy efficiency rating of buildings, or attract tenants or buyers interested in sustainable development.

5. Reduce energy loss: The nearby use of solar power reduces energy loss during energy transmission. Electricity is directly supplied to buildings from rooftop solar systems, without the need for long-distance transmission lines, thereby reducing transmission losses and grid burden.
