Different photosynthetic power plants “harvest” the energy before plants use the “products” of their own photosynthesis, and convert the energy into electricity to run energy-efficient equipment. energy.
The principle of photosynthesis is to convert light energy into chemical energy. Water molecules in plants are broken down into hydrogen and oxygen atoms. The electrons produced during the decomposition process will help plants produce beneficial substances for the growth of sugar bodies. . Plants try to extract electrons before using them to produce sugars.
The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. Silicon atoms have 4 electrons. If atoms with 5 electrons, such as phosphorus atoms, are mixed with pure silicon, it becomes a semicondN-type uctor. If atoms with 3 electrons, such as boron atoms, are mixed with pure silicon, it is formed. a P-type semiconductor. When P and N types are combined, a potential difference is formed on the contact surface and becomes a solar cell. When sunlight irradiates the PN junction, the holes move from the N pole region to the P pole region, and the electrons move from the P pole region to the N pole region, forming an electric current.
Has anyone installed photovoltaic power generation in their home? Come in and tell me
The “Fishing and Complementary Photovoltaics” photovoltaic power generation project combines photovoltaics and fishing. Above Photovoltaic panels produce electricity and agriculture thrives in the water below, allowing three-dimensional and comprehensive use of space.
Constructionof the “fishing and complementary light” photovoltaic solar project takes full account of the needs of agriculture. The distance between piles is maintained in the design, and the coverage area of. photovoltaic panels are reasonably arranged to give full play to their sunshading effect and reduce the photosynthesis of water surface plants, inhibit the reproduction of algae to a certain extent, and at the same time improve the water quality, it lowers effectively the water surface temperature and; reduces water evaporation, providing a good growth environment for fish.
Project design
The project has a total investment of 1.8 billion yuan, a total water area of 4,492 acres, a total installed capacity of 200 megawatts and an estimated annual average electricity production of around 220 million kilowatt hours. Assuming that an average household consumes 200 kWh of electricityty per month and 2,400 kWh of electricity per year, it can meet the electricity consumption of 100,000 households for one year, which is equivalent to saving 70,400 tons of electricity. standard coal.
My house is equipped with photovoltaics, and I am also in this sector.
It's simple, you install photovoltaics, and the simplest is to let the seller do it for you. Process, but now that there are no more grants, there's actually not a lot of process to go through. However, when installing photovoltaics, you must first contact the local State Grid (in bold). and italics represent important), and then you can install bidirectional. To put it simply, for example, if you install a 5 kW electricity meter, ordinary households usually have a surplus. Therefore, when State Grid calculates your household electricity bill, it does this. Thatwill calculate the electricity you produce based on its purchase price (usually thermal energy) / price of water and electricity (cheapest)), then deduct the money so you can 'use and will calculate the money. This is also the recommender's premise to say that if you install PV you don't have to pay.
The average household I'm referring to is that your home does not have a superpower . For example, your house has a hotel-level air conditioner/water heater/cold room. However, your home already uses this level of power. equipment, and are you still thinking about photovoltaic energy production? , usually 1-2p air conditioner + refrigerator + electric water heater + electricity for three meals a day + watching TV daily and other small things can be easily handled by a 5 kW power station.
If you don't have blots of money on hand, only less than 50,000, do you want to buy a stock fund? So this is really nonsense. Install a photovoltaic system, first of all, as I said before, you don't have to worry about the electricity bill. If you are in a rural area, you don't have to worry about food. The electricity bill will be lower. and we can still eat meat from time to time. This thing is more convenient than putting 50,000 yuan in Yu'e Bao in the bank. As long as there is nothing wrong with it, it will continue to make money, more than Yu'e Bao and banks, and more stable than stocks and funds.
To put it simply, what are you doing with photovoltaic power generation? Go to sleep and everything will be fine. There is everything in the dream.
By the way, there is a misunderstanding. Photovoltaic energy production does not depend on the heat of the sun (even the heat of the sun is still a weakening), buts of the brightness of the sun. as long as you can simulate general lighting from the sun, it can also produce electricity. If the brightness is not sufficient, it will not be able to produce electricity. But you can also use thin film solar cells, which can do this as well. produce electricity at night. However, the efficiency is not high, and overall it is not as good as conventional components (cost, payback time and profit time)
