1Working principle
The grid-connected photovoltaic power generation 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, realizes the connection with the grid, and transmits electricity to the grid. The flexibility of this power generation system lies in the fact that when the sunshine is strong, the photovoltaic power generation system supplies the AC load with excess electric energy while feeding it into the grid; and when the sunshine is insufficient, that is, the solar cell array cannot provide enough electric energy for the load, It can also obtain electrical energy from the grid to supply power to the load.
Due to the high cost of solar systems, photovoltaic solar power generation was mostly only used in some dedicated independent operating systems, such as aerospace, border defense islands, or demonstration projects in remote areas.
The emergence of new photovoltaic materials and new technology, and the continuous decline of product prices, the continuous improvement of conversion efficiency, the introduction of advanced power electronic devices, microprocessors, and the application of advanced control strategies, all of which have led to the research and promotion of photovoltaic on-grid technology.
It is becoming every family every people can use solar systems possible day by day, and photovoltaic utilization is also gradually developing towards urban grid-connected photovoltaic power stations, residential photovoltaic building integration and low-power household photovoltaic grid-connected systems

How to choose one suitable solar on grid system?
1, confirm your grid type and voltage
2, confirm the size of your roof top or ground where solar panels will be installed
3, choose the suitable solar panels and inverter
A 20kW solar system is a substantial solar energy installation that can generate a significant amount of electricity.
A 20kW solar system typically consists of multiple solar panels, also known as photovoltaic (PV) modules, which convert sunlight into electricity through the photovoltaic effect.
The number of solar panels required for a 20kW system can vary depending on the wattage of individual panels.
Typically, panels with a capacity of 290 watts are used, so a 20kW system may consist of approximately 76 panels.
The amount of sunlight and solar irradiation received in a specific location greatly influences the energy production of a solar system.
Regions with higher solar irradiation levels and ample sunlight will generally increase energy output.
Solar panels’ efficiency and ability to convert sunlight into electricity impact energy production.
Higher-efficiency panels can generate more electricity from the same amount of sunlight.
Additionally, panel degradation over time should be considered, as it can gradually reduce energy production.
