Photovoltaic (solar energy)
Power) is a Solar photovoltaic power generation system (solar
force
System) is a new type of power generation system, which uses the photovoltaic effect of semiconductor materials of solar cells to directly convert solar radiation energy into electric energy. There are two modes of independent operation and grid-connected operation.
Solar Photovoltaic effect, short for photovoltaic (PV), also known as photoelectric effect, refers to the phenomenon that uneven semiconductors or parts combined with semiconductors and metals generate potential difference under illumination.
People usually don't regard the wiring system connecting photovoltaic module and inverter as the key component, but if the special cable for solar energy application is not used, the service life of the whole system will be affected. Solar energy systems are usually used in harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, the field temperature of solar energy system will be as high as100 C. At present, all kinds of materials we can use are PVC, rubber, TPE and high-quality cross-linking materials. Unfortunately, rubber cables rated at 90°C or even PVC cables rated at 70°C are often used outdoors, which obviously will greatly affect the service life of the system. ——2065 438+04 China Photovoltaic Market Application Analysis.
For photovoltaic applications, outdoor materials should be based on ultraviolet rays, ozone, drastic temperature changes and chemical erosion. Using low-grade materials under this environmental stress will cause the cable sheath to be fragile and even decompose the cable insulation layer. These conditions will directly increase the loss of cable system, and at the same time, the risk of cable short circuit will also increase. In the medium and long term, the possibility of fire or personal injury is higher.
During installation and maintenance, the cable can run on the sharp edge of the roof structure, and at the same time, the cable must bear pressure, bending, tension, cross-tensile load and strong impact. If the strength of cable sheath is not enough, the cable insulation layer will be seriously damaged, which will affect the service life of the whole cable, or lead to short circuit, fire, personal injury and other problems.
Photovoltaic technology has many advantages: for example, there are no mechanical moving parts; In addition to sunlight, it does not need any other "fuel" and can work in direct and oblique sunlight; At the same time, solar module does not need maintenance, and the operating cost is minimized; Moreover, from the choice of venues, it is also very convenient and flexible, and roofs and open spaces in cities can be applied. Since 1958, the solar photovoltaic effect has been applied to the energy supply field of space satellites for the first time in the form of solar cells. Today, from the automatic parking meter and the energy supply of roof solar panels to the vast solar power generation center, its application in the power generation field has spread all over the world.

How to calculate the power generation of solar photovoltaic power station?
Generally, a 2 MW rooftop solar power station generates about 8 kWh per day and 2.5 million kWh per year, which can save 864 tons of standard coal, 2,392 tons of greenhouse gas carbon dioxide, 652 tons of dust and smog, 72 tons of atmospheric pollutants sulfur dioxide and 36 tons of nitrogen oxides. Moreover, this rooftop photovoltaic power station can also be equipped with an intelligent cleaning device for solar panel robots to realize regular automatic cleaning, which saves trouble and energy. . Advantages and disadvantages of solar photovoltaic power generation Compared with the commonly used thermal power generation system, the advantages of solar photovoltaic power generation are: ① there is no danger of exhaustion; (2) Safe and reliable, without noise and pollution discharge, absolutely clean (pollution-free); (3) Not limited by the geographical distribution of resources, the advantages of building roofs can be utilized; (4) local power generation and power supply can be realized without consuming fuel and erecting transmission lines; ⑤ High energy quality; ⑥ Users are easy to accept emotionally; ⑦ The construction period is short, and the time required for obtaining energy is short. Disadvantages: ① the energy distribution density of irradiation is small, that is, the occupied area is huge; (2) The energy obtained is related to meteorological conditions such as four seasons, day and night, sunny and rainy.

What is the cost per kWh of photovoltaic power generation?
According to the current market price of photovoltaic power generation crystalline silicon battery module is about 0.703 USD/watt, please refer to the following data: 20 1309 18. Average AVGCHG% silicon solar module 0.99 0.55 0.703-0.002-0.28% thin film solar module 0.94 0.49 0.6. The estimated market price of 03 -0.00 1 -0. 17% complete sets of photovoltaic power plants is about 1.4- 1.5 USD/watt, which is less than 10 yuan/watt, that is1watt. The annual available electricity is 65,438+0,000 kWh. According to the recognized life span of 25 years, the total electricity obtained in 25 years is 25,000 kWh, regardless of the reduction of efficiency (the average annual reduction is not more than 1%). According to the current national policy, photovoltaic power generation can be connected to the Internet or desulfurized at a price of 0.43 yuan/kWh, plus an additional subsidy of 0.45 yuan/kWh. That is to say, if the total cost is 0.88 yuan/kWh, the electricity fee for 25 years will be 22,000 yuan, and the investment of 1 kW photovoltaic power station will be 1 10,000 yuan, that is to say, the power station investment will be recovered in about 10 years.

What is the cost of solar photovoltaic power generation?
1. The installation cost of photovoltaic power station mainly includes photovoltaic modules (solar photovoltaic panels), inverters (DC voltage to AC voltage) and distribution boxes. Plus the construction cost. The following is what I found on the industry platform "Carbon Synergy" APP (quoted in July 2020 16). Carbon surplus synergy ① Single crystal 355W module of photovoltaic module Longji, LR4-60HPH 355W, 543 yuan each, namely 1.53 yuan /W (including tax). Other products, such as Artes 340W, namely 1.44 yuan /W 2 frequency conversion Guruiwatt three-phase 17KW growth attmid, cost 3850 yuan each, namely 0.23 yuan /W 3 distribution box, such as Chang Song 10kW distribution box, costs 699 yuan/block. If it is an integrated solution, according to the carbon surplus cooperation solution (including three blocks, power distribution service and insurance), the investment cost of photovoltaic power generation is already very low. The price trend of photovoltaic upstream industrial chain, as of May 27th, the component price has dropped to 1.56 yuan /w ... The price mentioned in this article is the actual price given by the service provider in July. 2. Operation and maintenance costs of photovoltaic power plants At present, the service life of photovoltaic power plants is about 25 years, which requires regular maintenance. Let's take the carbon bank as an example. In addition to providing installation and construction services, Zhejiang Carbon Bank operates and maintains 200 yuan every year (different service providers have different prices), and pays extra for replacing faulty equipment. According to the calculation of 25 years, the operation and maintenance cost is more than 5000 yuan. You should know that the current cost is not high according to the market price in 2020. Data sources: Carbon Silver Network, Carbon Surplus Collaborative APP, and Carbon Silver Photovoltaic.
