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: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:What are the devices needed for PV systems?
Solar photovoltaic power generation system is mainly composed of solar cell matrix, controller, battery, inverter and other equipment
Q:Solar photovoltaic system
State subsidies for distributed PV policy: distributed generation price subsidies by 0.42 yuan / kWh (subsidies for a period of 20 years), distributed photovoltaic power generation system of power grid, power grid enterprises in accordance with the local coal-fired power by electricity (0.44 yuan /kWh) acquisition.
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 is the system voltage of solar panels
Solar panels (Solar panel) is composed of one or more solar cells to form a solar panel. A solar cell is a semiconductor device that converts light into electrical properties, which can convert solar radiation energy on its surface into direct current
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: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:Solar power generation system suitable for home, how much is the cost of a set?
Configuration of a household solar power system is about ten thousand to $twenty thousand
Q:What are the components of the solar photovoltaic system?
EVA: a high quality EVA film with a thickness of 0.78mm, which is made of UV resistant agent, antioxidant and curing agent, is used as a sealing agent for solar cells and a bonding agent between glass and TPT. High light transmittance and aging resistance.
