工商業(yè)光伏發(fā)電的施工要求認(rèn)識不足,對工程質(zhì)量和技術(shù)環(huán)節(jié)的重視程度不夠,從而引發(fā)施工問題。本文就工商業(yè)建筑在光伏發(fā)電設(shè)計(jì)和施工中的注意事項(xiàng)展開討論。
Because some construction enterprises do not know enough about the construction requirements of industrial and commercial photovoltaic power generation, and do not pay enough attention to project quality and technical links, construction problems are caused. This paper discusses the precautions of industrial and commercial buildings in the design and construction of photovoltaic power generation.
工商業(yè)屋頂安裝光伏發(fā)電的一個突出的問題是屋頂或場地產(chǎn)權(quán)問題,由于光伏發(fā)電使用壽命長,投資成本也高。在產(chǎn)權(quán)不明晰的場地或屋頂建設(shè)光伏發(fā)電站會給電站建成后的使用和收益產(chǎn)生很多不確定因素。因此在建設(shè)工商業(yè)電站前期要充分做好場地產(chǎn)權(quán)、靜態(tài)投資和運(yùn)維投入、收益分配、風(fēng)險承擔(dān)等一系列可行性分析,制定好切實(shí)可行的解決方案。
A prominent problem of industrial and commercial roof mounted photovoltaic power generation is the property right of the roof or site. Due to the long service life of photovoltaic power generation, the investment cost is also high. The construction of photovoltaic power station on the site or roof with unclear property rights will bring many uncertain factors to the use and income of the power station after completion. Therefore, in the early stage of the construction of industrial and commercial power plants, a series of feasibility analysis should be fully done on site property rights, static investment, operation and maintenance investment, income distribution, risk bearing, etc., and practical solutions should be formulated.

對于建筑屋頂承重能力差、不能直接采用混凝土重樁的情況,可采用不銹鋼繩牽拉固定。需要說明的是牽拉支架的不銹鋼繩不能直接打膨脹螺絲固定在屋頂上,通常是固定在建筑外墻或其他相對穩(wěn)定堅(jiān)固的混凝土立柱上。
If the building roof has poor bearing capacity and concrete piles cannot be directly used, stainless steel rope can be used for pulling and fixing. It should be noted that the stainless steel rope of the traction bracket cannot be directly fixed on the roof with expansion screws, but is usually fixed on the external wall of the building or other relatively stable and solid concrete columns.
與地面光伏不同,屋頂光伏如果無法與原建筑屋頂混凝土鋼筋直接連接的時候,可根據(jù)當(dāng)?shù)仫L(fēng)力情況采用混凝土重樁放置在屋頂上,通常每個獨(dú)立樁的重量不宜超過100kg。對于經(jīng)常受到臺風(fēng)襲擾的沿海地區(qū),建議采用條形混凝土樁,不僅能確保光伏陣列系統(tǒng)的抗風(fēng)能力,還可以減少光伏電站對建筑屋頂?shù)膲毫Α?/div>
Different from the ground photovoltaic, if the roof photovoltaic cannot be directly connected with the roof concrete reinforcement of the original building, the concrete heavy piles can be placed on the roof according to the local wind conditions, and the weight of each independent pile should not exceed 100kg. For coastal areas frequently disturbed by typhoons, it is recommended to use strip concrete piles, which can not only ensure the wind resistance of photovoltaic array systems, but also reduce the pressure of photovoltaic power stations on building roofs.
連接支架的鋼螺栓須與混凝土澆筑一體,不能用膨脹螺栓代替混凝土基礎(chǔ)與支架間的連接。特別要說明的是:不能在平屋頂屋面上直接打孔或安裝膨脹螺栓,以免破壞原建筑屋面的防水結(jié)構(gòu)。通常建筑屋頂?shù)闹饕δ苁欠烙旰捅?。光伏透光組件安裝在建筑屋頂上不僅要牢固可靠,抗風(fēng)抗打擊,防雨的問題不容置疑,要嚴(yán)格做好密封防雨措施。
The steel bolts connecting the support must be integrated with the concrete pouring, and expansion bolts cannot be used to replace the connection between the concrete foundation and the support. In particular, it is not allowed to directly drill holes or install expansion bolts on the flat roof to avoid damaging the waterproof structure of the original building roof. Usually, the main functions of building roofs are rainproof and thermal insulation. Photovoltaic light transmission modules installed on the roof of the building should not only be firm and reliable, but also be resistant to wind and rain. There is no doubt that sealing and rainproof measures should be strictly taken.
此外屋頂光伏電站的陣列支架要做好防雷接地,如果原建筑已有屋頂防雷接地系統(tǒng),要將光伏支架接地端與原建筑屋頂防雷接地引出線可靠并接。關(guān)注我們

In addition, the array support of the roof photovoltaic power station shall be well grounded for lightning protection. If the original building has a roof lightning protection grounding system, the grounding terminal of the photovoltaic support shall be reliably connected with the lightning protection grounding lead of the original building roof.
