ON GRID SOLAR PANEL
What Is a Grid Connected PVSystem?
The generated electricity will be fed into the grid, and the grid is used as an energy storage device. When the electricity load is large and the solar power is insufficient, electricity is purchased from the national grid. When the load is small or the electricity cannot be used up, the excess electricity will be sold to the national grid.
On grid photovoltaic systems have a connection to the public electricity grid via a suitable inverter, the direct current output by the solar array is transformed into alternating current of the same amplitude, same frequency and same phase with the power grid voltage, and realizes the connection with the power grid and the transmission of electric energy to the power grid.
On Grid Solar Panel
Residential PV generation is a model of using PV power stations as consumer goods, residents buy them at home and install them on the roofs for "spontaneous use, and surplus electricity is connected to the Internet". Photovoltaic power plants can be connected to the grid, and the excess electricity is sold to the national grid, and then used by residents themselves. Industrial and commercial PV power generation refers to suitable installation in enterprises, institutions, schools, hospitals, commercial buildings, office buildings, hotels, shopping malls, industrial plants, and other large-scale electricity consumers. The distributed grid direct pv systemcan be consumed locally, offsetting part of the electricity consumption of online purchases and saving energy. The user's electricity bill, or the full Internet access, is exchanged for income.
How Does Solar Panel Grid ConnectionWork?
The on grid photovoltaic system can convert the DC power output by the solar cell array into AC power with the same amplitude, frequency, and phase as the grid voltage, and realize the connection with the grid and the transmission of electric energy to the grid. The flexibility of this kind of power generation system is that when the illumination is strong, the photovoltaic power generation system supplies the AC load while sending the excess power into the grid; when the illumination is insufficient, the solar modules cannot provide enough power for the load. On grid photovoltaic system can also obtain electrical energy from the grid to supply power to the load.
What Is On Grid Solar Panel System?
On grid photovoltaic system is a new investment model that can be used by itself and the surplus power can be sold into the State Grid to obtain income. On grid pv systemcan be installed in areas with sufficient light and no shelter. On grid solar pv system is suitable for residential roofs, industry and commerce, medium and large ground stations. The on grid photovoltaic system is mainly composed of photovoltaic modules, inverters, grid connected cabinets, metering meters, etc., with power ranging from 3-1000KW.

During the daytime, under the light condition, the solar cell module generates a certain electric potential, and through the series and parallel connection of the module, the solar cell square array is formed, so that the voltage of the square array reaches the system input voltage requirement. The battery is then charged by the charge/discharge controller to store the electricity converted from light energy. At night, the battery bank provides input power for the inverter, and through the role of the inverter, the DC power is converted into AC power and delivered to the distribution cabinet, which is powered by the switching role of the distribution cabinet. The discharge of the battery bank is controlled by the controller to ensure the normal use of the battery. The on grid photovoltaic system should also have load limiting protection and lightning protection devices to protect the system equipment from overload operation and lightning strikes and maintain the safe use of system equipment.
Regardless of the form, the working principle is that photovoltaic modules convert light energy into direct current, which is transformed into alternating current under the action of the inverter, and finally realizes the function of electricity consumption and Internet access.
Sunrise can offer a solar PV system price to customers to save your photovoltaic system cost.

Benefits of On Grid Solar System
NO
01
RESOURCE UTILIZATION
Solar energy, a clean and renewable natural energy, is used to generate electricity without consuming non-renewable and carbon-containing fossil energy with limited resources, without emissions of greenhouse gases and pollutants, in harmony with the ecological environment, and in line with the strategy of sustainable economic and social development.
NO
02
COST REDUCTION
The generated energy is fed into the grid, and the grid is used as the energy storage device to save the battery. Compared with the independent solar photovoltaic system, the construction investment can be reduced by 35% to 45%, so that the cost of power generation is greatly reduced. The secondary contamination of the battery is avoided by eliminating the battery, and the mean time free from failure of the system is improved.
NO
03
INCREASE SELLING POINTS
The perfect combination of photovoltaic cell modules and buildings can not only generate electricity but also serve as building materials and decoration materials so that the full use of material resources can play a variety of functions, which is not only conducive to reducing construction costs but also improve the building's scientific and technological content and increase selling points.
On grid pv system in Different Application
Photovoltaic + industrial and commercial roof
The industrial and commercial roof area is large, with the characteristics of flat roof, large electricity consumption, and high electricity price, so the installed capacity is large and the power generation is also large.
Photovoltaic + Transportation
The application scenarios of photovoltaic + transportation include airport photovoltaic power stations, photovoltaic railway stations, photovoltaic high-speed rest stations and even photovoltaic roads.
Photovoltaic + school
The school has a relatively broad roof, good structure, and stable power consumption; the installation of photovoltaic power stations can play a role in energy conservation and emission reduction, and promote the construction of an environmentally friendly and energy-saving campus.
Photovoltaic + water plant
Photovoltaic power generation utilizes the roof, sedimentation tank, biochemical tank and contact tank of the sewage treatment plant to install solar photovoltaic panels on it, which has a unique space advantage.
How does On-grid Solar System Work?
Grid connected solar pv systemaccessories include: solar modules, inverters, support brackets and cables, combiner boxes, AC and DC power distribution cabinets and monitoring systems. Among them, combiner boxes, AC and DC power distribution cabinets and monitoring systems will be installed according to the actual scenario.
How grid-connected power generation generates energy: The grid-connected power generation system converts the received solar radiation energy into high-voltage direct current through high-frequency direct current conversion through photovoltaic arrays. sinusoidal alternating current.
