Solar panel

1. IntroductionPhotovoltaic (PV) module can convert solar radiation directly into electricity power. As an approach of utilizing clean, renewable green energy, it bears the advantages of no-motion components, simple structure, long life-span and convenient operation. 2. Operation & Maintenance2.1 PV modules should be installed at where there is no shade, and the surface of PV module should be vertical to sunlight, to utilize most of the sunshine. 2.2 The angle between PV module and ground would be favorable when equal to local latitude plus 5 degree to obtain maximum output. 2.3 PV modules should be handled gently during process of installation and maintenance, collision and knocking is strictly forbidden to avoid breakage of the package glass. 2.4 The front surface of PV module should keep clean regularly. 2.5 Do NOT touch the output terminals when PV module is under sunlight. Electricity can shock burn or cause death. 2.6 Do NOT use terminals signed by + and - reversely, which mean anode and cathode, respectively. 2.7 Professional experiences are needed for those personnel who are responsible for installation, maintenance and operation of PV modules. 3.
