Some large commercial buildings have open and flat roofs, which are the places with the long sunshine time. How can we use flat roofs to build pv mounting system?
1.The solar carports on the flat roofs: Some commercial building’s roofs are used as parking spaces, with which can be established the carport with solar panels. The system can not only meet the requirements of parking spaces,but also use solar energy to generate and save the electricity which could be used for the whole commercial building’s daily usage. The carport usually includes the solar mounting steel structure with modules. The roof of the shed adopts BIPV, replacing the roof of the shed with photovoltaic modules, achieving power generation function at the same time, as well as the role of shading and rain prevention, and can reduce the temperature under the shed by about 15℃.
2.Flat roof solar ballast: This is another Solar Mounting Racking, which is very economical and applicable. On low-sloped flatter rooftops, many building owners don’t want to poke holes through the roof. Ground mounting has resolved this concern: Solar arrays which are installed on top of embedded parts cannot penetrate the roof. That’s where solar ballast comes in. Concrete blocks are placed throughout a project to secure an array to the roof and prevent wind lift or other movement. Different ballast types are selected according to their own needs.The solar ballast usually includes base rail, rail connector, rear leg, front leg and different inter/bottom/end clamps.
3.Flat Concrete Roof Mounting System : Solar Mounting Bracket shall be located on the flat roof with the cement base. This solar mounting structure usually includes U shaped bolt, Solar Panel Rail Brackets U(21X41,41X41,41X52,41X62mm),connector,clamps and hex bolts. All the profiles and accessories are pre-assembly, which is convenient to be installed in the short time. The most advantages of this type mounting is: The U shaped bracket’s sizes and hole’s size/position are common universal, which is more easy for installer to assemble the structure. The cold bending production efficiency is very high,which makes Rail U profiles are very popular. Some producers usually makes extra quantity as inventory in their warehouse (like GRT solar energy). When the PV project need Pv Panel Brackets urgently, the installer/EPC can easy buy from local market.
Above all, no matter what kind of mounting system you choose for the commercial flat roofs,try to connect with at least three different contractors before you make decision, and understand the warranties or guarantees from your installers.
