Working principle

The wind-solar hybrid power generation system is mainly composed of wind turbines, solar panel arrays, intelligent controllers, battery packs, multi-functional inverters, cables, supports and auxiliary parts. Wind power is used for power generation at night and when there is no sunlight in rainy days, and solar power is used for power generation in sunny days. In the case of both wind and sun, both play a role at the same time, realizing the function of all-weather power generation, which is more economical, scientific, practical.

Advantages

Fully utilize wind energy and solar energy for complementary power generation without external power supply;
Exemption from construction of substations, erection of high and low voltage lines and high and low voltage distribution systems;
It has the characteristics of day and night complementation and seasonal complementarity, the system is stable and reliable, and the cost performance is high;
The maintenance workload of power facilities and the corresponding expenses have been greatly reduced;
Independent power supply, will not affect the electricity consumption of all users in the event of natural disasters;
Low voltage power supply, safe operation and simple maintenance.
