Non-compliance with this installation instruction may result in property damage and/or physical injury. ET Solar will not be liable for compensation of any loss or injury caused by this type of non-compliance. 2 Codes and regulations The mechanical and electrical installation of PV systems should be performed in accordance with all applicable codes, including electrical codes, building codes and electric utility interconnection requirements.
3.1 Safety precautions for installing a solar photovoltaic system Regular safety: ET Solar Modules are designed to meet the requirement of IEC 61215 and IEC61730, application class A. Modules rated for use in this application class may be used in system operating at greater than 50VDC or 240W, where general contact access in anticipated.
www.etsolar.hk Keep children well away from the system while transporting and installing mechanical and electrical components. Completely cover all modules with an opaque material during installation to prevent electricity from being generated. Do not wear metallic rings, watchbands, ear, nose, or lip rings or other metallic devices while installing or troubleshooting photovoltaic systems.
4 Mechanical Installation 4.1 Installation requirement ET Solar bears NO responsibility for any damage caused by the use of unsuitable or inappropriate mounting / fixing systems. Before starting with the mounting process, the strength of mounting / fixing structure on the panel field must meet the local loading condition, e.g.
www.etsolar.hk Shading on the module will reduce electricity production. Do not install the module near equipment or in locations where flammable gases can be generated or collected. A minimum angle of 10° is recommended in order to make ...
www.etsolar.hk Mounting with clamping hardware 4.2.2 When choosing clamp mounting method, please be sure to use at least four clamps on each module, two clamps should be attached on each long sides of the module. Depending on the local wind and snow loads, if excessive pressure load is expected, additional clamps or support would be required to ensure the module can bear the load.
www.etsolar.hk Installation position and static loads 4.2.3 Maximum Static load(test load) of the PV module by: front 5400pa and back 2400pa, these values can vary depending on installation method of the modules (please refer to the following installation methods) Installation Methods and corresponding max pressure relation Installation methods Clamp Clamp...
When using lay-in lugs, the grounding conductor should be inserted into the opening indicated in the figure, and secured using the set screw. Expect for equipment grounding, ET Solar recommends the negative pole of PV module array is connected to earth during all PV system installations. That...
EN50618(or IEC62852 ) All field wiring cables must have large enough cross- sectional areas approved for use at the maximum short-circuit current of the PV module. ET Solar recommends that installers use only sunlight resistant cables for direct current (DC) wiring in PV systems. The recommended minimum wire size should be 4 mm²(12AWG) and must be subject to the local national codes...
Notice, bypass diode is not the overcurrent protection device. If the diode is suspected to be defective, the installer or system providers shall contact ET Solar. Please do not try to open the junction box by yourself.
ET Solar recommends the following maintenance items to ensure optimal performance of the module. 6.1 Cleaning This manual covers the requirements for the cleaning procedures of ET Solar PV modules. Professional installers should read these guidelines carefully and strictly follow these instructions. Failure to follow these instructions may result in death, injury, or property damage.

www.etsolar.hk not have"self-cleaning" function as those installed at 10° or larger tilt angles. The back surface of the monofacial module usually does not need to be cleaned. When cleaning the back of the bifacial module, avoid any sharp objects that may cause damage or penetrate the base material.
The maximum water pressure recommended is 4 MPa (40 bar) Method B: Compressed Air ET Solar recommends using this method to clean the soft dirt (like dust) on modules. This technique can be applied as long as the method is efficient enough to clean the modules considering the on-site conditions.
