It's a solar system that is connected and synchronized with the power grid. So, the electrical load will be fed from both sources which share to each other in feeding it.
In cloudy days or at night where the solar system generation is low or even is not exist, the electrical load takes its power requirements from the power grid. And in sunny days where solar generation exceeds load power requirement, the load take all its power requirement form the solar system and surplus solar generated electricity will go to the power grid to be used elsewhere.
If you plan to design and install a grid tie solar PV system for your home, you will want to know how much electricity the system can produce each year. Now we will take the roof of 60m2 as an example to make this calculation. At present, the household solar power system generally adopts the monocrystalline silicon solar panel and polycrystalline silicon solar panel. Its specification is generalized as 36V 280W, and the single piece of solar panel generally has an area of 1.8 m2...
The basic principle of solar water pump system is to use semiconductor solar cells to convert solar energy directly into electricity, and then use various motors to drive water pumps for water lifting from deep wells, rivers, lakes and other water sources. In some small and medium power solar pump systems, brushless DC motor is often used as the driving motor, but in some larger power solar pump systems, asynchronous AC motor is also used as the driving motor. In the case of AC asynchronous motor as driving motor, solar pump inverter(solar variable frequency drive) is usually used to control.
