When installing solar panels on the cement flat roof of some factory buildings, PVkingdom suggest to build a heightened bracket and then install the photovoltaic roof. After completion, it can directly become a sun-proof and waterproof storage space.

Building a heightened bracket system with a PV roof on factory buildings is a practical and beneficial solution. It effectively leverages existing roof space to generate clean energy and provide weather-protected storage, while also enhancing building efficiency and lowering operating costs. While initial investment and structural assessments are critical, the long-term advantages and cost-savings often make this a compelling choice for factories looking to maximize their resources and embrace sustainable practices.

Necessity:

Maximizing Roof Utilization: Factory roofs are often large, flat, and underutilized spaces. Installing a raised PV system allows for dual-purpose use – generating clean energy and creating additional storage space. This is especially valuable in industrial settings where space is often at a premium.

Enhanced Cooling and Energy Efficiency: The raised structure creates an air gap between the PV panels and the original roof, reducing heat transfer. This significantly lowers the building's internal temperature, reducing the need for air conditioning and lowering energy costs for the factory.

Protection of Original Roof: The elevated PV roof acts as a protective barrier for the factory's original roof, shielding it from harsh weather conditions like direct sunlight, rain, snow, and hail. This can extend the lifespan of the underlying roof structure and reduce the need for frequent repairs.

Water Management: The elevated structure can also improve drainage and water management on the roof. By directing water away from the original roof surface, it helps to prevent water ponding and potential leaks.

Financial Benefits: Beyond electricity generation, the added storage space allows the factory to optimize operational efficiency. There is reduced costs for additional storage infrastructure, and additional revenue from potential savings on cooling costs, leading to a quicker return on investment (ROI).

Advantages of This Installation Method:

Dual Functionality: The primary advantage is the dual use of the roof – for power generation and as a sun-proof, waterproof storage area. This efficiently utilizes space.

Cost Savings: Reduces electricity costs and potential cooling costs, while also potentially eliminating or reducing the need for a dedicated storage building.

Extended Roof Lifespan: Protects the existing roof from harsh weather, leading to reduced maintenance and replacement costs.

Improved Thermal Comfort: Creates a cooler indoor environment through the air gap created between the PV roof and the existing building structure.

Enhanced Water Management: The raised design aids in efficient water drainage, preventing ponding on the roof and related issues.

Increased Property Value: Improves the value of the factory by adding valuable assets that create clean energy and offer additional storage capacity.

Environmental Benefits: Contributes to reduced reliance on fossil fuels and lower carbon emissions.

Customizability: The design of the raised bracket structure can be customized based on the factory's specific needs and roof dimensions.
