Components of Solar Energy System CNBM-K7 (3KW)


PV Array:
Convert sunlight instantly into DC electric power. Formed by the solar modules (also called photovoltaic modules) in accordance with the system requirements for series and parallel.


Solar Charge Controller:
A charge controller may be used to power DC equipment with solar panels. The charge controller provides a regulated DC output and stores excess energy in a battery as well as monitoring the battery voltage to prevent over charge or over discharge. An inverter can be connected to the output of a charge controller to drive AC loads.


Converts DC output power of photovaltaic soalr panels into standard AC power for use in the local off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary commercial appliances.


Battery banks:
Stores energy when there is an excess coming in and distribute it back out when there is a demand. Solar PV panels continue to re-charge batteries each day to maintain battery charge.

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: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:What are the devices needed for PV systems?
Solar cell array. The solar cell array is composed of a solar cell composite plate and a square bracket. Because the single voltage of solar cells is generally low, so usually they are connected in parallel and series solar panels have practical value, as an application unit, and then according to the power requirements of a plurality of application unit series and parallel composition of solar cell array. Solar panels (some semiconductor materials, mainly polysilicon and silicon and amorphous silicon, through a certain process to assemble) is the main component of the solar photovoltaic system, the highest value is also part of the solar photovoltaic power generation system. Solar panels in the light of the circumstances, the battery absorbs light energy, the two ends of the battery appears to be the accumulation of different charges, that is, the light generated voltage, which is the "photoelectric effect". Under the action of the photoelectric effect, the electromotive force is generated at both ends of the solar cell, and the light energy is converted into electric energy.
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: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: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 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.
