solar batteries testing in order to determine whether the battery module to work properly, before the installation must be tested on the solar cell, installation personnel must contrast when measuring solar cell manufacturer's technical manuals. The open circuit voltage measurement must be the sun in the solar energy battery components, heating before because the output voltage of the solar cell components will reduce with the increase of temperature. Short circuit current measurement directly influenced by the sunshine intensity. Unless you can accurately measure the sunshine intensity, only the output current characteristics of the solar cell module for approximate estimate. In the process of measurement, make the solar cell component perpendicular to the plane of the face to the sunshine. Most of the solar energy battery components field measurement results and the data given in the product specification differs in 5 - Less than 10%, the best measurement under the condition of the strongest sun at noon battery components. Installation method 1) Bracket installation method. A single solar arrays can use a simple bracket device installation. Two Angle plating steel stents through screw fixed on the wall and roof of the building, the other pair with stents with connection at the end of the solar cell component framework, two stents linked together to form a simple, durable, cheap to install solar cell phalanx bracket device. Support device can rotate so that depending on the season to adjust Angle, so as to optimize the performance of the photovoltaic system. 2) Post installation method. Directly fixed on the ground of the column used to install the solar cell phalanx. Generally speaking, the diameter of 5 - 7 cm steel tube is very suitable for as the material of the support structure. Using this method of installation, Angle also can be adjusted according to the season, in order to optimize the performance of the photovoltaic power generation systems. 3) The ground installation method. When installing solar array on the ground, should base on the ground is made in advance, and then the metal framework on the base, the final install solar arrays on the frame. Install the framework usually includes two parallel channel. Use screws to fix horizontal support aluminum on the channel beam. Horizontal support aluminium profile should have high strength, in order to prevent the blown away. The solar cell phalanx of aluminum frame with screws in the upper and lower levels of support on the aluminum ( In the preset Angle of fixed) 。 Can also purchase or production with adjustable Angle bracket device, so that according to the season to adjust the Angle of the panels. Galvanized steel is applied to directly installed on the concrete base metal framework, because the lime content in concrete corrosion of aluminum. In addition, screws, nuts and washers shall be made of stainless steel to prevent corrosion. In the final options prior to the installation position of the solar cell array, should be detailed assessment of local climate conditions and soil bearing capacity. Ground installation requires a base, have enough strength to avoid the damage caused by excessive pressure. At the same time, the base should be able to withstand the tangential wind ( Lateral movement) Force. Refer to the local building standards can provide the basis for determine the basic requirements. Before installation, ensure that the supporting components conform to these standards. 4) Roof installation method. In the roof installed solar arrays have four kinds of commonly used methods: installed stents, independent, direct installation and integration. ( 1) Bracket installation. In bracket installation mode, the solar cell array is supported by metal frame, and presents the preset Angle. Installed on the bracket, a set of square solar cells through the screw on the roof. This kind of installation method will increase the load bearing of the roof and the wind stress. However, due to the air flow path is completely surrounded by the solar cell array, the solar cell array can remain relatively low working temperature, thus improve the efficiency. Some stents installation method can adjust the Angle according to the season, improve the efficiency of photovoltaic power generation systems.
