Q:Rooftop solar system
Now the national clean energy, photovoltaic power generation policy is more than 10kW can be free of charge, but the price of electricity recovery is very low, cumbersome procedures.
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 PV systems
Fifth distributed photovoltaic power generation implementation of self occupied, power over the Internet, the nearest consumptive, power regulation, operation mode. The power grid enterprise uses advanced technology to optimize the operation and management of power grid, and provides the system support for the distributed photovoltaic power generation operation. To encourage investment business entities with the same power supply area of the power users in power grid enterprise cooperation in a variety of ways to achieve the nearest consumptive distributed photovoltaic power generation.
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 [1]. 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:Solar photovoltaic system
Analysis of economic benefits: 50kW distributed photovoltaic PV power plant total operating period: 25 years of this project on average generating capacity: the annual average generating capacity of 200kWh: 73000kWh, 25 years of total power: 1825000kWh residential electricity price: 0.55 yuan /kWh local coal-fired power benchmark price: 0.44 yuan /kWh (the case): Total investment the total investment of about 450 thousand yuan, equivalent to 9 yuan / watt.
Q:How to calculate the income of photovoltaic system
There are two kinds of algorithms, one for the total solar energy and the total electricity consumption, a solar photovoltaic power generation in real-time and real-time electricity.
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: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?
Solar photovoltaic power generation is suitable for families but to look at your location and sunshine time, before the country without a policy or honest with general electric, energy saving is a national matter we the people pay so without saving
Q:What are the components of the solar photovoltaic system?
Photovoltaic system is composed of solar cell array, battery, charge and discharge controller, inverter, AC distribution cabinet, automatic solar tracking system, automatic solar module dust removal system and other equipment. The equipment is in the light (either sunlight or other light generated by the light) case, battery to absorb the light, the two ends of the cell appeared heterocharge accumulation, namely "photo voltage", which is "photovoltaiceffect". Under the effect of the photovoltaic effect, both ends of the solar cell produce electromotive force, which converts light energy into electrical energy, which is an energy conversion device. Silicon solar cells are generally divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells three
