Under the same condition of ensuring optimal installation angle, in areas with good lighting conditions, such as Inner Mongolia, the annual electricity generation can reach 1.6 degrees/W. The annual electricity generation in Chengdu, Sichuan can only reach about 0.7 kWh/W. Eastern regions of China such as Jiangsu, Zhejiang and Shanghai have a simple and easy-to-remember formula for generating electricity, which is to generate electricity once a year per watt. After determining the area, you can find out how many kilowatt hours of electricity a photovoltaic module can produce in that area in a day. For example, a 450W photovoltaic module in Shanghai can produce 450 kilowatt hours of electricity in a year, or 1.23 kilowatt hours of electricity per day on average.
1 kilowatt of photovoltaic energy production per year
1.825 billion kilowattheures of electricity.
Under the optimal tilt angle, the equivalent sunshine hours in Beijing are 1,576 hours per year, with an average of 4.32 hours per day. Under normal circumstances, December sees the worst sunshine, with one. averaging just 2.47 hours per day, with the best sunshine in May, averaging 6.17 hours per day.
Therefore, the total electricity production for the whole year is 5 kW*80%*1,576 h=6,304 kWh, the average daily electricity production for the whole year is of 17.27 kWh and the average daily electricity production in December is 5 kW. *80%*2.47h=9.88kWh, the average daily electricity production in May was 5kW*80%*6.17h=24.68kWh.
Precautions for photovoltaic power plants
For photovoltaic power generation systems that operate for a long time, the impact of dust accumulation on the panelsneaux cannot be underestimated. The dust on the surface of the panel has the function of reflecting, scattering and absorbing solar radiation, which can reduce the transmission of the sun, causing the panel to receive less solar radiation and reduce the output power. Its effect is proportional to the accumulated thickness. dust.
Shading is the most taboo problem in photovoltaic power plants. Pay attention to design and installation, and even more attention to subsequent operation and maintenance. Common shadows mainly include bird droppings, dust, shadows of trees, buildings, fallen leaves and branches, etc.
1000 degrees. Photovoltaic power generation is a technology that uses solar radiation to convert solar energy into electrical energy. The installed capacity of a 1 kilowatt photovoltaic plant is 1,000 watts, which representsnd usually from various factors such as geographical location, weather, quality of equipment and technical level. Under normal circumstances, the average electricity output of a 1 kilowatt photovoltaic plant per year is generally around 1,000 kilowatt hours. Photovoltaics, short for Solar Power System, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It works independently and works in parallel. manners.
