Q:Solar PV systems
Third to encourage all types of power users, investment companies, professional contract Energy Service Companies, individuals as a project unit, investment and construction and operation of distributed PV projects.
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
Q:Solar power generation system suitable for home, how much is the cost of a set?
Then the 1000 Watt Solar panel price is 5000 yuan -10000 yuan, regardless of inverter and power generation, but with the power of the household appliances related to property, if you use ordinary household appliances 100 watt power inverter, then with a 300-500 tile, if you are using a blender or high power desktop computer although only 100 watts -200 watt but starting current, so the best 1000 Watt inverter. The price of the inverter is 800-2000 yuan (depending on the power and performance price).
Q:Rooftop solar system
Solar power generation, per square meter of power generation in 120W or so, the cost per square meter in 1500 yuan, the greater the area the lower the price
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 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:How to calculate the income of photovoltaic system
Hypothesis: 1 my peak electricity price of 1 yuan / degree, the flat price of $0.7 / degree, the local coal desulfurization unit benchmark price of 0.4 yuan / degree. 2 my home at noon to 1 points solar power generation of 90 degrees, power consumption of 40 degrees; in the afternoon from 5 to 6 solar power generation of 10 degrees, power consumption of 60 degrees. Results: 1 according to the total solar energy power generation and the total energy consumption calculation two times my solar power electricity is 100 degrees, 100 degrees, more than electricity difference is zero; so I save electricity 85 yuan, receive subsidies 35 yuan, the total revenue of 100kWh * [(1 + 0.7) /2 + /kWh = 0.35 yuan) 120 yuan.
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: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.
