工商业屋顶由于其屋顶面积大，电费价格高，用电量大，利用闲置屋顶做光伏发电系统是非常划算的。利用工商业建筑闲置的屋顶，与光伏发电结合起来，让屋顶成为一个小型的清洁电力发电站，既为企业节省电费支出，又能改善屋面的隔热状况，让厂房更加节能，从而为企业带来*的稳定利润。

Due to its large roof area, high electricity prices, and high electricity consumption, it is very cost-effective to use idle roofs for photovoltaic power generation systems in industrial and commercial areas. By utilizing the idle roofs of industrial and commercial buildings and combining them with photovoltaic power generation, the roofs can become a small clean power generation station. This not only saves electricity expenses for enterprises, but also improves the insulation condition of the roofs, making the factory more energy-efficient and bringing stable profits to the enterprise.

根据结构不同，工业建筑屋顶大致分为混凝土屋面、钢结构屋面（根据彩钢瓦类型大致又可分为角驰型、直立锁边型、波浪型等类别）。分布式光伏屋面类型不同，可采用的安装方式也不同。光伏工程人员说，分布式光伏系统安装前，首先必须考虑房屋结构的安全性，必须根据国家现行的建筑结构荷载规范要求，结合现场实际情况，委托专业机构，对房屋进行结构承载力复核验算，特别是钢结构房屋的结构承载力验算，如有不满足规范要求的，必须对房屋加固处理，才能保证房屋安全可靠。

According to the different structures, industrial building roofs can be roughly divided into concrete roofs and steel structure roofs (which can be roughly divided into categories such as angle galloping, vertical locking edge, and wave shaped according to the type of colored steel tiles). The installation methods that can be adopted vary depending on the type of distributed photovoltaic roof. Photovoltaic engineering personnel said that before installing a distributed photovoltaic system, the safety of the building structure must be considered first. According to the current national building structure load code requirements, combined with the actual situation on site, a professional organization must be commissioned to conduct a structural bearing capacity review and verification of the building, especially the structural bearing capacity verification of steel structures. If there is any non-compliance with the code requirements, the building must be reinforced, Only then can we ensure the safety and reliability of the house.

光伏工程人员说，影响光伏系统安装的因素主要为屋面的承载能力、防水情况、建筑使用年限、遮挡物的多少以及屋顶面积等。混凝土屋面的承载能力基本都能符合分布式光伏要求，另外需要特别注意一下屋顶上管道的分布情况；而对于钢结构屋面来说，则需要重点对其承载能力进行核算。现有技术已经可以提供优质钢结构屋面冷加固、屋面涂层维护、屋面施工及防水等综合服务，将光伏发电与钢结构屋面实现*融合，zui大化保障发电效率和建筑安全。厂房屋顶光伏发电系统--河南省内地区都可安装

Photovoltaic engineering personnel say that the main factors affecting the installation of photovoltaic systems are the load-bearing capacity of the roof, waterproofing conditions, building service life, the amount of obstructions, and roof area. The bearing capacity of concrete roofs can basically meet the requirements of distributed photovoltaics, and special attention should be paid to the distribution of pipes on the roof; For steel structure roofs, it is necessary to focus on calculating their bearing capacity. The existing technology can provide comprehensive services such as high-quality steel structure roof cold reinforcement, roof coating maintenance, roof construction, and waterproofing, integrating photovoltaic power generation with steel structure roofs to maximize power generation efficiency and building safety. The rooftop photovoltaic power generation system of the factory building can be installed in all regions of Henan Province

随着气温的下降，人们也开始担心光伏发电系统能否抵抗恶劣天气的危害。光伏工程人员说，分布式光伏系统要按照国家出台的建筑结构荷载规范严格把控质量关，才能更好地保障安全，应对冬天雨水积雪等恶劣天气。

As the temperature drops, people are also beginning to worry about whether photovoltaic power generation systems can resist the harm of adverse weather. Photovoltaic engineering personnel say that distributed photovoltaic systems need to strictly control quality in accordance with the national building structural load specifications in order to better ensure safety and cope with adverse weather conditions such as winter rain and snow.

近日，在某地区水质净化二厂的能源站中，为合理利用和开发清洁新能源，厂房屋顶上方就架起一座104.5KW的分布式太阳能光伏发电站。并网发电后，预计年可以发出40万度绿色电力，除具备可观的经济效益之外，对节能减排、环境治理、减少雾霾等均做出相应的贡献，具有良好的环境和社会效益。

Recently, in the energy station of the second water purification plant in a certain area, a 104.5KW distributed solar photovoltaic power station was erected above the roof of the plant to make reasonable use of and develop clean new energy. After grid connected power generation, it is expected to generate 400000 kWh of green electricity annually, which not only has considerable economic benefits but also makes corresponding contributions to energy conservation, emission reduction, environmental governance, and reducing haze, and has good environmental and social benefits.
