Summer how to solve the problem of photovoltaic power generation systems?

Summer is how to reduce the electricity! Summer influence the elements of photovoltaic power generation is high temperature, high temperature will have an impact on component, will also affect inverter. During the peak temperature coefficient of photovoltaic modules in - probably 0. 38 ~ 0. Between 44% / ℃, temperature

the summer how to reduce electricity? In summer, the high temperature is the key factors influencing the photovoltaic power station power generation. High temperature will affect the components and inverter. In the meantime, the peak temperature coefficient of photovoltaic modules about - 0. 38 ~ 0. 44% / C, that is, when the temperature increases, the photovoltaic modules of a lower capacity, in theory, every time the temperature increases, the output by about 0. 44%. According to the calculation of 20 mw photovoltaic power station, heating components to produce the output of about 200 degrees every day. Although 200 degrees of electricity is not much, but the continuous high temperature can affect not only power, and in severe cases will cause high temperature fire equipment downtime and equipment. And, of course, this is the probability of not very high, but does not rule out unexpected happens. So, we should be how to deal with this situation? First, although the inverter protection grade reaches IP65, but would still need a shading treatment. Under normal circumstances, the level of domestic inverter reaches IP65, wind resistance, dustproof and waterproof performance. Inverter is composed of many components, these components have their service life. Under the condition of high temperature, even if the whole machine reaches IP65 rating, in the case of continuous heating, the service life of the components will be natural. Therefore, under normal circumstances, household photovoltaic inverter will be equipped with shading devices in the system, in order to reduce the temperature of the equipment. Secondly, for the photovoltaic power station on the ground, to ensure that no weeds. In order to eliminate the influence of high temperature and photovoltaic power station not only ventilation, but also pay attention to the external environment. For example, some of the photovoltaic power station is located in remote areas, power plant usually surrounded by weeds and lush vegetation, this will also affect the activity of air volume, thus reducing power. It is necessary to remove weeds and vegetation in time. Third, components and inverter should keep ventilation, to ensure that the air can be recycled. Rooftop photovoltaic power plant ventilation cooling without consideration, mainly for photovoltaic (pv) the users of agricultural greenhouse, general can do so: in the Settings of the side of greenhouse roof photovoltaic modules, vent is set in backlight blind area, on the premise of not affect crop growth, largely for ensuring the temperature of the photovoltaic modules suitability. Frequency converter device environment should be well ventilated, to ensure that the air convection. Fourth, the regular inspection is very important. After the completion of photovoltaic power station, operation maintenance cannot careless, especially in the summer, need regular inspection, to ensure that equipment heat dissipation is good, the air circulation more than empty, weeds and obstacles that can affect the heat should keep clear of in time. Whether the ground station or family photovoltaic power station, the construction of the plant is not equal to a stable income. Especially in the summer, even if the power generation in advance, also pay attention to the operation and maintenance, but also pay attention to the heat dissipation of pv systems. Only in this way, photovoltaic power plant can run smoothly.
