日本自家消费型光伏屋顶系统
2023-12-08 17:17According to the Japanese government's plan, photovoltaic power generation will account for 14% to 16% of its total electricity demand by 2030, which means Japan must double its photovoltaic power generation capacity in less than 10 years. However, Japan, as one of the countries that developed photovoltaics earlier, has already developed and used land suitable for photovoltaic power generation, and now there is very little land left that can be developed. It is predicted that in the next 10 years, rooftop solar power (TRS) may replace photovoltaic power plants and become Japan's main growth driver.
Understanding Japanese roof types and developing PV fixtures suitable for various roof types has become an urgent need for the Japanese market.
Japanese roofs are diverse and there are many types of roofing materials used. Due to limited space, this time I will first introduce to you the folding panel roof and the suitable solar photovoltaic fixtures among the metal roofs with the highest proportion.
Folded panels were developed with a focus on cross-sectional construction, typical of metal roofs, and their design blends well with large, long roofs, strength and economy.The folded plates can be directly covered on the beams and the main building, without the need for roof substrates, which shortens the construction period. It can show toughness even in strong wind areas and has strong rain resistance.
采用厚度0.6～1.2mm的钢板形成较大的高度。这是一种将紧框架以约3mm至7mm的间隔安装在梁上并直接固定在梁上的施工方法。根据接合方式的不同，主要有（1）接缝式、（2）搭接式、（3）插接式。
Use steel plates with a thickness of 0.6~1.2mm to form a larger height. This is a construction method in which tight frames are installed on the beam at intervals of about 3mm to 7mm and fixed directly to the beam.According to the different joining methods, there are mainly (1) seam type, (2) overlap type, (3) plug-in type.
将附在紧框架上的紧固配件（通过焊接固定在横梁上）夹在两片金属屋面材料的端部之间，并用电动封缝机（夹紧机）将其缠绕紧固，使其防水性极佳。这是一种经济的方法，可以降低成本，因为屋顶只需重叠屋顶夹紧接缝处即可完成，并且不再需要螺栓。
这种屋顶上面有突出的部分，可以根据凸出的形状和尺寸来选用目前已开模的适合夹具，我司目前可提供的夹具如图。
Clamp the fastening fittings attached to the tight frame (fixed to the beams by welding) between the ends of the two pieces of metal roofing material and wrap and tighten them with an electric seam sealer (clamping machine) to make them waterproof Sex is excellent. This is an economical method that reduces costs because the roof is completed by simply overlapping the roof clamping seams and bolts are no longer required.
This construction method involves joining two metal roofing materials to a tight frame with hangers (fasteners) and installing caps over the joints so that no bolts protrude from the roof surface and the roof looks clean.
在屋顶打孔，虽然会加防水橡胶垫和封口胶等防漏雨措施，总还是会有风险。所以日本客户们都迫切希望能多开发屋顶上用的不打孔方案。
That's all for this introduction,we will continue to introduce other types of roofs and suitable roof photovoltaic fixtures in the future, so please continue to pay attention to the Xiamen Powerstone.
