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?
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
To search and collect profit (in all spontaneous terms): the average recovery of funds on average generating capacity = * (distributed generation electricity subsidies + residential electricity price =200* (0.42+0.55) =194 were the first year of the recovery of funds = daily recovery funds *365=194*365=70810 yuan investment recovery period = total investment / average recovery of funds is about =450000/70810=7.06 years. 6.5 years 25 years average annual net income = recovery funds * (20 -6.5) + daily average generation price *365 * electricity days *5 years =70810*13.5+200*0.55*365*5=1156680 yuan
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:How to calculate the income of photovoltaic system
Photovoltaic panels can only generate electricity, storage batteries need to match. The peak power output of photovoltaic panels = peak wattage X local sunshine time X efficiency coefficient of general domestic parts of the sunshine time is 4 hours (per day), the efficiency of PV system with battery is about 0.7. That is to say, 1000W system, the average daily electricity is about 2800WH (2.8 degrees) or so in accordance with the distributed PV subsidy of 0.35 yuan / degree, solar photovoltaic power generation more than the Internet how exactly?
Q:I want to install a full set of domestic solar heating equipment does not know how much money to spend, please.
Save 50% equivalent to an annual savings of more than 3300 heating projects; water consumption in accordance with an average of 200 liters a day, remove the winter has been deducted 120 days, the remaining 240 days probably with hot water total: 48 tons, natural gas energy is calculated according to the cost of the cheapest words per ton of hot water heating costs 15 yuan, annual water savings of 720 yuan. Two of the total savings of 4000 yuan, according to the energy prices coefficient is estimated at less than 10 years to recover the full investment, another ten years of savings more than 40 thousand yuan.
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: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?
Frame: aluminum alloy frame with high strength, strong resistance to mechanical impact. Is also the most valuable part of home solar power. A device for converting direct current into alternating current. Since the solar cells and batteries are DC power, while 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 photovoltaic power generation system for grid connected operation. 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.
