Abstract


With the intensification of the global energy crisis , and industrial production strengthen energy -dependent countries in the world have invested a lot of manpower , material and financial resources of renewable energy research . Solar energy as a green , clean, renewable energy major application form of light thermal applications , photovoltaic applications and photoconductive lighting three categories , including photovoltaic applications is the use of semiconductor silicon materials , solar cells convert light energy into electrical energy . Firstly, proceed from photovoltaic applications focus on integration in the form of photovoltaic technology in the steel building . Based on the connection of PV modules and steel building and construction , integrated system of photovoltaic steel structure is divided into tilted square style style of curtain wall box , plug-in , single -point , flat horizontal and paste the mire six types of integrated system . The highest degree of integration is affixed to the well-formed , the worst is tilted square style . Then proposed an embedded the modular PV module design ideas , the basic idea is to use the grid regional aspect to the formation of the connecting bracket , each PV module directly embedded into a single grid , modular installation , ease of operation maintenance. Under the guidance of this idea , the embedded module PV modules border connecting bracket and other components of the detailed design , research and development component size 1646mm × 874mm × 50mm . For the research and development of photovoltaic modules , mechanical testing , the test as well as the static water tightness test of the relationship between the power generation efficiency and force . 5 (2400Pa) mechanical testing of PV modules loaded into the center point of the battery plate deflection value 19.505mm, to meet the requirements ; force after power test of the power generation efficiency of photovoltaic modules by up to 4.65% of the maximum attenuation , less than 5% of the specification ; static water tightness test reaction embedded modular PV module has a good water tightness performance . Finally, on the basis of the argument in the trial embedded modular photovoltaic components used in the actual demonstration project , detailed design and discusses their PV systems . Demonstration project of 548 embedded module PV modules installed system peak power 98.28KW , an annual generating capacity reached 9.92KWh 25 during the life savings of standard coal amounted to 967.5 tons .
