Why solar photovoltaic power plant capacity will reduce in the winter?

Close to a lot of photovoltaic power station users find home photovoltaic power station capacity to reduce a lot, then find the installer complaint about product problems. In fact need not too nervous, we often say 1 kw power 4 - 6 degrees/day, this is a year of electricity the average

recently, many of the photovoltaic power station users find their home photovoltaic power station capacity decreased a lot, they found that the installer to complain about the product have a problem. In fact, there is no need too nervous. We often say 1 kw capacity is 4 - every day 6 degrees, this is the average annual output. Spring and autumn are the peak period of photovoltaic power generation, photovoltaic power generation are out of season in winter. In addition to the winter sunshine time is shorter, winter sunshine weaker and photovoltaic power station capacity is low, there are several main factors which cannot be ignored: first of all, smoke and dust due to hot, dry weather, the winter air dust content is more than other seasons, winter haze weather than other seasons. Absorb and reflect the light in the suspended substances in the air, which leads to the surface of the module receives the sun down significantly. Weather lasted for a long time, if the smoke particles found on the surface of a pv module will accumulate and the module cover is formed on the surface, cause pollution of the surface of the battery module and further reduce the electricity. Keep the panels clean not only can improve the output, but also can effectively maintain pv module, because long-term accumulated particulate matter quality can lead to module produces a large amount of heat, cause hot spots, the service life of this could threaten module, or cause a fire. two Snow snow module, only a small portion of solar energy photovoltaic module through the snow exposure, which affect photovoltaic power generation. ( 1) Installation of photovoltaic power station in yi snow region tip: A. Large Angle of photovoltaic panels installed solar panels within the scope of the good Angle to large Angle installation, can reduce the accumulation of snow speed, avoid the clearing trouble from time to time. B, when installation components, and the ground keep a certain distance in this way, will not slide down the snow accumulation at the bottom, so the snow will pile up and slowly to cover the entire component. ( 2) Also how to maintain the photovoltaic power station: general advice don't wait for the snow is too thick to cleaning, so as to avoid freezing parts. Hot water cannot be used for irrigation of photovoltaic panels. Uneven heating and cooling can severely damage the photovoltaic panels. Can use the soft object push the snow down, be careful not to cut glass, because it will decrease the amount of light transmission. ( Bounce gently with the tennis on the tilt of the photovoltaic panel, let the snow slide down, this is a good way ~) D, parts have a certain carrying capacity, but can't step on the above washing, can lead to crack or damage to the component, affect the service life of parts. E, snow removal must be clean, don't look down on the ice cream bar, is part of the blocking will disable the entire photovoltaic panels, which can lead to efficiency significantly reduced. In addition, the reflection of the snow slightly promote photovoltaic power generation. If the snow does not cover parts, the snow on the ground like a mirror reflecting sunlight, thus increasing output.
