Q:Rooftop solar system
Solar panel power generation, then the proposed size of the proposed group, mainly the power substation and storage of electrical equipment is very expensive, the highest conversion rate in the 17%-20% efficiency is very low, not as good as plant photosynthesis
Q:What is the system voltage of solar panels
System voltage refers to the number of solar panels composed of a solar power generation system, the maximum DC voltage of the power system.
Q:How about the price of solar power generation system
Photovoltaic power generation system can not buy cheap, cheap product quality is not good to use expensive. Photovoltaic power generation system can be used to invest in financial products, general household photovoltaic system 7~9 can recover the cost of power system can be used for more than 25 years, 25 years after the power attenuation of about 20%, if the poor quality of the products are generally 2~3 years can be reduced by 20% and must keep their eyes open several more formal manufacturers so when buying light V system, quality quality assurance production factory.
Q:Solar power generation system installation which precautions, ah, there is a need for special attention
Solar power system consists of solar panels, solar controller, battery, inverter and other load. Solar power system installation note has the following 1, the battery plate array need to consider the installation azimuth angle, tilt angle. 2, to avoid blocking between the panels. Including the surrounding buildings (poles, building eaves, etc.). 3, stent placement stability and firmness. 4, the distance between the line and the bus box location. Try to walk a short distance and average. 5, related accessories to meet the system requirements (such as wiring column, with wire diameter etc.). 6, the terminal should be firm, to prevent the virtual connection or disconnection.
Q:How to calculate the income of photovoltaic system
Hypothesis: 1 my peak electricity price of 1 yuan / degree, the flat price of $0.7 / degree, the local coal desulfurization unit benchmark price of 0.4 yuan / degree. 2 my home at noon to 1 points solar power generation of 90 degrees, power consumption of 40 degrees; in the afternoon from 5 to 6 solar power generation of 10 degrees, power consumption of 60 degrees. Results: 1 according to the total solar energy power generation and the total energy consumption calculation two times my solar power electricity is 100 degrees, 100 degrees, more than electricity difference is zero; so I save electricity 85 yuan, receive subsidies 35 yuan, the total revenue of 100kWh * [(1 + 0.7) /2 + /kWh = 0.35 yuan) 120 yuan.
Q:Solar PV systems
Article 1 in order to regulate the construction of distributed photovoltaic power generation project management, promote distributed photovoltaic applications, according to the "People's Republic of China renewable energy law", "People's Republic of China, People's Republic of China" power law "administrative licensing law", and the "State Council on a number of opinions" to promote the healthy development of the PV industry, these measures are formulated.
Q:What are the main features of solar photovoltaic systems
Compared with the commonly used thermal power generation system, the advantages of photovoltaic power generation:No danger of depletion; safe and reliable, no noise, no pollution, absolutely clean (pollution-free); not subject to geographical distribution of the resources, can take advantage of the building roof; for example, areas without electricity, and complex terrain area; no fuel consumption and the erection of transmission line can be on-site power supply high quality energy;; users emotionally receptive; the construction period is short, get energy to spend a short time.
Q:Solar power generation system how to choose?
The power of the solar panel is determined by the efficiency of the battery, the material assembled into the solar panel and the process. The process and material of the big brand is generally no problem, but the battery is also high and low, the price difference is also very large, to ask about the efficiency of battery and components. 250W single crystal battery pack 18.6% is sufficient, the standard specification 1650mm*992mm, the components are generally in the; 250W polycrystalline battery sheet in the 17.6% sufficient, standard specifications, components generally in the 15.3%.
Q:Household solar photovoltaic power generation system connected to the grid, how much money?
Sold to the power supply bureau 0.45 yuan once, the state subsidy fee of $0.42, a year issued 3000 kwh.
Q:What are the devices needed for PV systems?
Solar cell array. The solar cell array is composed of a solar cell composite plate and a square bracket. Because the single voltage of solar cells is generally low, so usually they are connected in parallel and series solar panels have practical value, as an application unit, and then according to the power requirements of a plurality of application unit series and parallel composition of solar cell array. Solar panels (some semiconductor materials, mainly polysilicon and silicon and amorphous silicon, through a certain process to assemble) is the main component of the solar photovoltaic system, the highest value is also part of the solar photovoltaic power generation system. Solar panels in the light of the circumstances, the battery absorbs light energy, the two ends of the battery appears to be the accumulation of different charges, that is, the light generated voltage, which is the "photoelectric effect". Under the action of the photoelectric effect, the electromotive force is generated at both ends of the solar cell, and the light energy is converted into electric energy.
