Features of Complete Solar System
Solar module:solar battery module(also called photovoltaic battery module)in series or in parallel according to the system requirements,the solar energy will change into electrical energy in the light of the sun and then output,it is the core component of solar photovoltaic system.
Controller: solar power controller is an important part of the solar power system, System of charging and discharging and load work automatically by its intelligent control and protection. Its performance directly affects the reliability of the system. Especially the battery life, overcharge or over discharge will be cause damage and even lethal damage for the battery.
Inverter: in solar photovoltaic power supply system, if it has the AC load, it is necessary to use the devices of the inverter. The direct current generated by solar modules or the battery release of DC into AC for load.
Battery:Stored up the electricity produced by the solar cell module produce,When illumination is insufficient or night or load demand is greater than the power produced by the solar cell module.Stored energy will be released in order to meet the load demand of energy,It is the solar energy photovoltaic system energy storage unit.Currently solar pv system commonly used is lead acid battery,For higher requirements of the system,Usually adopt deep discharge vrla battery ,deep discharge suction fluid type lead-acid battery,etc

- 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: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: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: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: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
- 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
- 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 are the advantages and disadvantages of small-scale solar power generation system?
- There are intermittent and random ground application, power generation and climatic conditions in the night or rainy days have little or no power; lower power density, under standard conditions, the solar radiation intensity on the ground received for 1000W/M^2. Large scale use, the need to occupy a larger area; the price is still more expensive, for conventional power generation 3~15 times, the initial investment is high.
- 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.
