Q:Rooftop solar system
2013 PV industry in Europe and the United States antitrust investigation, overcapacity led to the collapse of a large number of photovoltaic industry in Zhejiang, solar prices have fallen. This can be checked at any time online
Q:Solar PV systems
Fourth administrative department of energy of the State Council is responsible for the distributed photovoltaic power generation planning guidance and supervision and management; the local competent department of energy under the guidance of the State Council department in charge of energy, to supervise the construction of distributed photovoltaic power generation planning, the area; the national energy administration agencies shall be responsible for the supervision of the area of distributed photovoltaic power generation planning and policy implementation, network operation, the market fair and safe operation.
Q:How about the price of solar power generation system
At present, the domestic solar power generation system installed capacity, investment is also different, generally less than 30 thousand yuan in the 3KW, 5-10KW more than $9 per watt, for example, about 8KW or so. Solar power generation system consists of components, inverters, stents and other components, components can be found Yingli, Trina these, inverter Hefei sunshine, Foshan de nine for you to answer.
Q:What are the devices needed for PV systems?
Battery pack. The utility model is used for storing the electric energy generated by the solar array when illuminated by the light and can supply power to the load at any time. In the grid connected solar power generation system, the battery can not be added
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: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: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 how to choose?
The whole system is not equal to the power generation capacity of solar panels, but the system capacity. There are often many manufacturers to promote solar power generation efficiency how high how high, but if the choice of the circuit design and the inverter, loss of power is also completely different. For example, the centralized inverter for series system design, the efficiency of the system is about 88%, each brand inverter is also different. The advantage is that the inverter series system competition brand, low price; drawback is the solar panel is connected in series, the solar panels generating capacity of the whole system by the minimum power capacity decision, so once the board has not completely clean the ash layer is not uniform, or falling leaves or cloudy, the efficiency of the whole system will decrease.
Q:Solar power generation system installation which precautions, ah, there is a need for special attention
Pay attention to the basic power calculation is not enough! The reality is not up to
Q:What are the components of the solar photovoltaic system?
TPT: on the back of the solar battery cover of fluorine plastic film is white, the sun has reflection function, so the efficiency of components increased slightly, and because of its high infrared emissivity, can reduce the working temperature of the component, but also conducive to improve the efficiency of the component. Of course, the fluorine plastic film with the first solar cell packaging materials required for aging, corrosion resistance, air permeability and other basic requirements.
