- 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
- 7, the battery terminal to be strong (10 million can not be short circuit) to pay attention to the polarity of installation, to avoid the explosion and fire. 8, the controller has the corresponding distribution protection measures. But the wiring process should also pay attention to prevent polarity reverse, short circuit, etc.. Avoid unnecessary trouble. Pay attention to the angle of placing and avoid the rain. 9, with inverter system, inverter connected to be connected to the battery positive and negative poles. 10, the construction site must be open, in the installation of solar cells can not be tall buildings or other things blocking the sun. 11, the controller needs to choose low loss, good stability, long life controller. When the installation is clear that the controller is a common negative or common cathode design, so that the entire system connection, installation help.
- 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: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 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?
- To choose the right, we must first understand the composition of the system and the core of the power generation. Solar power system consists of solar panels or solar module, inverter, bracket, distribution box, cable and other accessories. The core components are solar modules and inverters, which directly determine how much electricity is generated and how many years to come. 5KW system, in the summer when the maximum amount of light radiation can be issued 23 days a day or so.
- Q:What are the devices needed for PV systems?
- Inverter. The utility model is a device for converting the direct current of the solar cell square and the storage battery to the alternating current, which is the key component of the photovoltaic grid connected power generation system. Since the solar cells and batteries are DC power supply, when the load is AC load, the inverter is essential. The inverter can be divided into independent operation inverter and grid connected inverter. The independent operation of the inverter is used for the independent operation of the solar cell power generation system, for independent load power supply. Grid connected inverter for grid connected solar power generation system, this paper introduces the photovoltaic grid connected generation system . As shown in Figure 1, the grid connected inverter by IGBT power switching devices, control circuit of the switching element is regular continuous open or off, so that the output voltage polarity alternating, DC input into AC output. The inverter can be divided into square wave inverter and sine wave inverter according to the output wave type. The square wave inverter has the advantages of simple circuit, low cost, large harmonic component, and the utility model can be used for a system with a few hundred watts and a low harmonic requirement. Sine wave inverter is expensive, but can be applied to various loads.
- Q:What are the advantages and disadvantages of small-scale solar power generation system?
- Solar energy inexhaustible, the earth's surface to accept the solar radiation energy, to meet the global energy demand 10 thousand times. As long as the installation of solar photovoltaic systems in the world's 4% deserts, the power can meet the needs of the world. Solar power is safe and reliable, does not suffer from the energy crisis or fuel market instability impact; solar energy everywhere, to the nearest power, do not have to avoid long distance transportation, long distance transmission line loss; solar energy without fuel, the operation cost is low
- 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.
