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
When the photovoltaic power generation system is combined with the building, it usually adopts the form of grid-connected power generation. Compared with the independent photovoltaic power generation system, this type of system has the following five outstanding advantages as follow:
1. On rainy days or at night, the power grid is used to supply power to the load so that the solar system can not need to be equipped with an energy storage battery, which can not only reduce the cost of the system, but also eliminate the trouble of maintaining and replacing batteries, and increase the reliability of power supply;
2. The electric energy generated when there is sunshine can be supplied to the load in the building, and if there is excess, You can harvest power with accessories such as inverters and lifepo4 battery,Then it can be fed back to the power grid; you also increase your income
3. In the grid-connected photovoltaic power generation system, it is not limited by the state of charge of the battery, and can access electricity to the grid at any time;
4. When designing the inclination angle of the solar plates array, the angle corresponding to the maximum amount of solar radiation that can be received throughout the year can be taken to maximize the power generation capacity of the solar battery array
5. In summer, the intensity of solar radiation is high, and the solar battery relatively more electricity. Summer is also the peak period of electricity consumption. The utilization rate of refrigeration equipment such as air conditioners is high, and the power consumption is large, playing a role in the power grid. The role of peak shaving.
