In their own home installation monocrystalline or polycrystalline solar photovoltaic power station is better

Someone said that the pv as good a piece of how power, photovoltaic power specification is rarely referred to. Because this is inline man this is perfectly normal a concept, but ignores the user does not know much about. Small make up today, with everyone a

some people say that photovoltaic power generation is very good, so that the specifications of the photovoltaic power generation is rarely mentioned. This is because for internal staff, this is the concept of a normal, but it ignores the fact that users don't know much about it. Today, xiao will take everyone talking about specifications and parameters of photovoltaic (pv) and see should choose monocrystalline and polycrystalline. Photovoltaic module battery 4 bb represent four grid lines, article 5 bb on behalf of the grid lines. At present, the mainstream of the market is 5 grid, a few manufacturers 12 grid. Gradually increase the main purpose of the power network is to improve the efficiency of the power. At present, 12 line is relatively rare and expensive. 12 line, also known as the main door, more MBB for short. Appearance is easy to identify. Photovoltaic modules single crystal polymorphic difference ( Visual features: monocrystalline silicon color dark; Have a round chamfer; Color is relatively uniform, polysilicon color is blue; Right Angle. Color is not like a single crystal. Careful observation will be slightly different) Because of monocrystalline and polycrystalline silicon wafer battery technology is different. Specification: photovoltaic power station commonly used components widely used on the market at present commonly used specifications are: 60 chip and 72 chip; The size of the composition of single crystal and polycrystalline ingredients are basically the same. 60 electronic component size: 1650 * 992 * 35 mm, 1640 * 992 * 35 mm; 72 board size: 1960 * 992 * 40 mm / 1956 * 992 * 40 ( The actual size shall prevail) Because the power of the same area will increase with the increase of power and natural. However, photovoltaic power station in the same installed capacity and power. And, of course, the battery unit conversion efficiency. So component cells of grid lines is the main reason of the increase gradually in order to improve the power components, this is what we call conversion efficiency. Of course, the efficiency of the batteries and photovoltaic module and the higher the price, the higher the price. If our roof area is finite, we can consider effective component, if our roof area is large enough, we can choose the commonly used components on the market. Is not valid because the same installed capacity, remember the number of the same installed capacity is not the same. Therefore, single crystal polycrystalline has its own advantages. Monocrystalline and polycrystalline collectively known as crystalline silicon, silicon use basically the same.
