Block chain sharing photovoltaic power station

1. I didn't see any specific solutions to the practical problems
on the contrary, it's like taking advantage of the hot spots to catch a wave of people's feet.

2. The application cases of Chongqing jinwowo analysis blockchain technology in the energy field are as follows:

1. Electric vehicle solutions, such as distributed charging piles and shared cars< Establish a personal energy system, buy and sell electricity, solar energy, gas and other energy

3. Support community energy model, battery management, and build an energy-saving power pool

4. Connect energy buyers with operators of renewable energy systems.

3. The problem of distributed access to the Internet has been solved. Now the power grid is basically centralized, while the blockchain is decentralized, which is consistent with the current photovoltaic power generation. Photovoltaic power generation is decentralized and multi-point.. The access to the power grid is uncertain and its performance is unstable, or some intervention may damage the power grid. In the algorithm of blockchain, there is consensus algorithm, which can solve this problem well,

4. As long as it is a formal blockchain, it is approved by the state.

5. Photovoltaic power generation is the use of solar photovoltaic power generation, referred to as photoelectric. Photovoltaic power generation is a technology that uses photovoltaic effect of semiconctor interface to directly convert light energy into electric energy. The key to this technology is solar cells. Photovoltaic shared power station is mainly reflected in the sharing of land between photovoltaic power station and crops or vegetables, which is a way to effectively use land resources, because the solar cell moles used in photovoltaic power station are supported by supports, while the ground will be empty, leaving most of the land, and this part of the land can be used to grow fruits and vegetables, especially fruits and vegetables, to achieve resource sharing.

6. The installation capacity with an area of about 5000 square meters can be about 500 kW, and the investment cost is about 5 million yuan

7. Yes

first of all, photovoltaic power generation can be regarded as the application of photovoltaic power generation, ranging from GW to several watts of a solar lawn lamp
secondly, as a power station, it can be divided into large-scale and small-scale. Large scale photovoltaic power station generally needs MW level, 100kW can only be considered as small-scale
thirdly, the so-called grid connection corresponds to the off grid. Grid connection means that the electricity generated by photovoltaic is directly converted into AC, and then transmitted to the place where the electricity is used, which is equivalent to selling to others. And off the grid, refers to the generation of electricity for their own use, do not sell
Fourth, when off grid, the battery is usually added to store the generated power, which can be used ring the day and at night. No battery is needed for grid connection. It can only be used for power generation ring the day, but not at night.

8. The quality and brand are different, and the cost is also different. You need to confirm the demand orientation of the other party, and then you can give the design after understanding. To make a photovoltaic power station, you need to make a high-quality one.

10. Is it investment of 300000 yuan or installation of 300000 watt photovoltaic power station? This number is quite different between the two units

for example, invest 300000 yuan to install a distributed photovoltaic power station, use it spontaneously, and use the remaining electricity online
according to the national standard price of 8 yuan / watt, about 37.5 kW can be installed at 300000 yuan In some places, the quoted price is 9 yuan / W or 10 W / W, and the price determines your installed wattage, so you can calculate the income by yourself:
the annual power generation in China is about 800-1900 kwh / kW, and the annual power generation in common areas is about 1200 kWh / kW, The annual power generation in northwest Xinjiang, Tibet and other places can reach above 1600 kwh / kW, the annual power generation in Northeast China is also higher, and that in coastal and southern cities is higher than that in inland China. The following estimate is based on the annual power generation of 1200 kwh / kW:
annual power generation: 37.5 kW * 1200 kwh / kW = 45000 kwh, that is, the annual power generation is 45000 kwh
income 1: state subsidy of 0.42 yuan / degree (national unified standard)
state subsidy for 20 years, settlement by power generation degree: 45000 degrees / year * 0.42 yuan / degree = 18900 yuan / year, 20 years total subsidy of 378000 yuan
income 2: provincial subsidy (some provinces and regions have no subsidy policy)
local subsidies are implemented according to local policies, and the subsidy policies are different across the country, which are settled according to the degree of power generation
income 3: Municipal subsidy (some cities have no subsidy policy)
local municipal subsidy is implemented according to local policies, and the subsidy policies are different across the country, which is settled according to the power generation degree
income 4: the generated electricity is self used, saving electricity cost
the annual electricity generation of 45000 kwh is self used, saving electricity cost every year: commercial electricity price of 0.85 yuan / kWh * 45000 kwh = 38250 yuan / year, saving electricity cost of 765000 yuan in 20 years. 20 years later, it will still be used by itself to save electricity< Income 5: the generated electricity can not be used up, and the state can recycle it.
the annual generated electricity can not be used up by itself, and the national policy is to recycle it at a price of 0.4161 yuan per kilowatt hour. The income depends on how much electricity you have left. You can get the annual income by taking the unit price of recycling, which is implemented every year and calculated quarterly! Why is the income calculated according to 20 years? Because the national subsidy is 20 years. The national quality standard is that the service life of PV moles is more than 25 years. Generally, the after-sales insurance of installation companies is 10 years, and that of insurance companies is 5 years

if it is a photovoltaic power station with an investment of 300000 watts, 300000 watts is equal to 300 kilowatts, calculate according to the above way! What's more, your question is purely for commercial use. Is the generating capacity for commercial use, or is it to invest in the construction of centralized photovoltaic power plants? If it is a centralized photovoltaic power station, the benchmark online price is 0.65 yuan / degree, 0.75 yuan / degree and 0.85 yuan / degree for class I, II and III areas,
