photovoltaic design life of 25 years. If you want your photovoltaic power station has a better power efficiency and longer service life, good after-sales service is not to be ignored. System problem is mainly due to the voltage not starting voltage, the inverter can't work and start, as well as the component or low power inverter to produce. Typical problem may arise in the system components including the junction box local fire burned and component. When the system is under warranty problems, can telephone contact professional maintenance staff recently, explain the problems in the system. Professional maintenance staff to answer this question, and, when necessary, to the scene to solve the problem. If the problem cannot be solved, please contact the installation personnel or operator. Need to check the parts should be carried out in accordance with the product instructions from any maintenance. Major maintenance of the system is to wipe components. Usually, large and rainfall frequent rainfall in the region does not need to manually wipe. Recommended cleaning once a week parts in the rainy season. Area increases with a large number of sand and dust cleaning. A large quantity of snow area, can keep clear of snow to avoid uneven snow melts influence power and absorb sunlight, and remove the trees or debris plug in time. In order to avoid in high temperature and strong light wipe components to inflict lightning damage and may damage the components and advice in the summer morning 6:00, winter morning before 7:00 or summer night before 7:00 and winter afternoon after 6:00 after clean parts. Advice first photovoltaic components with a soft cloth to clean the glass surface, and then with water at room temperature to clean again. Clean force should not be too large, so as not to damage the glass surface. Glass with a coating of parts should be paid attention to avoid damage to the coating. Photovoltaic modules on building shadow, leaves, and even guano will greatly affect the security of power system and power generation. System installation will consider various shadow effect of the system. Should be paid attention to in the daily maintenance, removal of photovoltaic modules, bird droppings and other stains around the branch. Is not recommended to install barbed wire, because the pv array installed wire could cast a shadow on the component parts, the formation of hot spot effect, thus affecting the whole efficiency of the photovoltaic power station. In addition, because all qualified pv module through the ice hockey impact test, under normal circumstances, the impact will not affect the performance of the module. Distributed photovoltaic power generation system is equipped with a lightning protection devices, so there is no need to disconnect. If there is a need to remove the snow snow back part, can use soft object pushes snow, and be careful not to scratch the glass. General advice don't wait for the snow is too thick to clean, to avoid parts surface ice. The output power of photovoltaic cells will reduce with the increase of temperature. Ventilation cooling can improve the efficiency of power generation. The most common method is to natural ventilation. Do not within 15 cm away from module on the back of the pile up sundry, lest affect the normal ventilation of the module. Photovoltaic power generation system according to the principle of photovoltaic effect converts solar energy into electric energy. It is no pollution and no radiation. Both inverter, power distribution cabinet and other electronic equipment through the electromagnetic compatibility test, harmless to the human body.
