CNBM On Grid System 7000W  with Certificate UL TUV CE

Product description

They range from small residential and commercial rooftop systems to large utility-scale solar power stations. Unlike stand-alone power systems, a grid-connected system rarely includes an integrated battery solution, as they are still very expensive. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.

Connection of the photovoltaic power system can be done only through an interconnection agreement between the consumer and the utility company. The agreement details the various safety standards to be followed during the connection.[4]

Solar energy gathered by photovoltaic solar panels, intended for delivery to a power grid, must be conditioned, or processed for use, by a grid-connected inverter. Fundamentally, an inverter changes the DC input voltage from the PV to AC voltage for the grid. This inverter sits between the solar array and the grid, draws energy from each, and may be a large stand-alone unit or may be a collection of small inverters, each physically attached to individual solar panels. See AC Module. The inverter must monitor grid voltage, waveform, and frequency. One reason for monitoring is if the grid is dead or strays too far out of its nominal specifications, the inverter must not pass along any solar energy. An inverter connected to a malfunctioning power line will automatically disconnect in accordance with safety rules, for example UL1741, which vary by jurisdiction. Another reason for the inverter monitoring the grid is because for normal operation the inverter must synchronize with the grid waveform, and produce a voltage slightly higher than the grid itself, in order for energy to smoothly flow outward from the solar array.

Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells.

Feature

Residential, grid-connected rooftop systems which have a capacity more than 10 kilowatts can meet the load of most consumers.[2] They can feed excess power to the grid where it is consumed by other users. The feedback is done through a meter to monitor power transferred. Photovoltaic wattage may be less than average consumption, in which case the consumer will continue to purchase grid energy, but a lesser amount than previously. If photovoltaic wattage substantially exceeds average consumption, the energy produced by the panels will be much in excess of the demand. In this case, the excess power can yield revenue by selling it to the grid. Depending on their agreement with their local grid energy company, the consumer only needs to pay the cost of electricity consumed less the value of electricity generated. This will be a negative number if more electricity is generated than consumed.[3] Additionally, in some cases, cash incentives are paid from the grid operator to the consumer.

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: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:Rooftop solar system
Solar panel power generation, then the proposed size of the proposed group, mainly the power substation and storage of electrical equipment is very expensive, the highest conversion rate in the 17%-20% efficiency is very low, not as good as plant photosynthesis
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: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: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: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: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: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.
