There are several types of solar energy production. One is crystalline silicon, including monocrystalline silicon and polycrystalline silicon, the other is amorphous silicon power generation, which is not crystalline silicon. There are thin layers of solar energy and flexible. solar energy. Due to the low conversion rate of amorphous silicon, crystalline silicon solar power generation is now more widely used.
Regarding your approximate power output per square meter per day, generally speaking, 1 square meter of crystalline silicon solar panels is equivalent to about 120-140W. If calculated as 120 W, the power of the sun at 6 a.m. day, i.e. 120*6=720WH. A 10W lamp depends on how many hours you use it per day and how many consecutive rainy days you need. If you use it 9 hours a day and 3 rainy days,then the battery panel. is 30 to 50 W.
Solar energy comes from celestial bodies outside the Earth (mainly solar energy). This is the enormous energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperatures. that humans need comes directly or indirectly from the sun. Fossil fuels such as coal, oil and natural gas that we need to live are all formed by various plants which convert solar energy into chemical energy through photosynthesis and store it in plants, then by plants and animals buried underground for a long time. period of geological time. In addition, water energy, wind energy, wave energy, ocean current energy, etc. are also converted from solar energy.
How much does the total investment of 60 square meters of solar energy production cost? ? How much electricity can be produced in a day?
Cost of 100 watts per square meter? more than 700 yuan, 300 square meters more than 30 kilowatts, one hour Generate 30 kilowatt hours of electricity. The cost is more than 200,000 yuan.
The State Grid doesn't want your electricity production.
Now is not the time to promote self-generated electricity.
Solar cells are too expensive to pay for yourself.
There's nothing wrong with experimenting on a small scale and having fun with it.
To answer this question, we need to consider the following aspects:
First of all, we need to know how much electricity a 60 square meter solar panel can generate. This value depends on the type and quality of the panels. Generally speaking, each square meter of panels can produce around 200 to 400 watt hours of electricity per day.
Assuming that each square meter of panel produces 300 watthours of electricity per day, then 60 square meters of panel can produce 18,000 watt hours of electricity per day.
Next, you need to consider the price of solar panels. Prices vary depending on market conditions and the type and quality of panels.
Assuming that electricity generation costs 10 yuan per watt hour, the total daily investment in 60 square meters of solar panels would be 18,000 watt hours × 10 yuan/watt hour = 180,000 yuan.
Finally, energy storage and export costs must be taken into account. These costs depend on the type and quality of panels and storage equipment, as well as electricity market prices.
Assuming that the cost of energy storage and power generation is 5 RMB per watt hour, then 60The total daily investment in square meters of solar panels requires the cost of this part: 18,000 watt hours ×5 yuan/watt hour = 90,000 yuan.
Therefore, the total investment for solar power generation on 60 square meters requires about 270,000 yuan.
As for the amount of electricity that can be produced each day, this value will vary due to many factors, including weather conditions, orientation and tilt angle of the battery panels, etc. . Generally speaking, a 60 square meter solar panel can produce around 1,800 to 3,600 watt hours of electricity per day.
Assuming that an average of 2,700 watt hours of electricity can be produced per day, a 60 square meter solar panel can produce approximately 27 kilowatt hours of electricity per day.
It should be noted that this value is only a rough estimate and the actual situation may be different.
