Components of Solar Energy System CNBM-K4 (300W)


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
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: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
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
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:Household solar photovoltaic power generation system connected to the grid, how much money?
General installation 3000W on the line, a full set of system down 21 thousand yuan. Print-Rite used solar panels, inverter with crystal fuyuan. Guilin Jinyang PV is so safe.
Q:How to calculate the income of photovoltaic system
There are two kinds of algorithms, one for the total solar energy and the total electricity consumption, a solar photovoltaic power generation in real-time and real-time electricity.
Q:I want to install a full set of domestic solar heating equipment does not know how much money to spend, please.
This area of solar heating system is divided into 4 parts: solar panels. Thermal energy water storage device. Thermal converter. Auxiliary heating wall. This system can be added with winter heating of buildings above 50% hot heat as a heat source for heating indoor floor heating systems, the spring and autumn three season can use gas or not using gas assisted heating (heat storage water tank can not increase the gas heating can be all-weather hot water).
Q:Solar power generation system how to choose?
Solar power generation technology is now very mature, the most important choice is to generate sufficient power, stable operation, reliable warranty and after-sales service.
Q:Solar power generation system suitable for home, how much is the cost of a set?
Configuration of a household solar power system is about ten thousand to $twenty thousand
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.
