At present, the power supply of various household or outdoor functional equipment mainly adopts power grid power supply, and part of household electrical equipment, such as a water heater, an outdoor street lamp and the like, adopts a photovoltaic panel or a fan for power supply, but has limited conversion efficiency, and also depends on mains power supply for maintenance and use.

In addition, the photovoltaic panel of the existing solar water heater is generally placed on a balcony, and is limited in installation; the photovoltaic panel on the street lamp is mainly fixed on the support of the rod, is easy to blow and incline, is firmly fixed, has low absorption efficiency towards fixed light, and has high manufacturing cost even if a steering tracking device is arranged.

Therefore, there is a need for an energy conversion device that is inexpensive to manufacture, stable and reliable in use, and capable of improving energy conversion efficiency.

The photovoltaic element is advantageously adapted to the shape of the pillar, whereby a greater stability with respect to strong winds and damage caused thereby is achieved.

However, the photovoltaic element is limited to a flexible photovoltaic element, the manufacturing cost is high, sunlight can only irradiate the photovoltaic panel from the front, only one side absorbs light, and the light absorption efficiency is low. In addition, when the photovoltaic panel is installed, an inclination angle is required to be set, namely, the angle of the photovoltaic panel for receiving sunlight, so that the photovoltaic panel can have the best receiving efficiency no matter the solar panel is lifted to fall within 10 to 14 hours. And when outdoor installation, outdoor environment is all comparatively complicated, probably has the shielding of building or trees around, and partial photovoltaic board can not receive sunshine, can cause the waste of photovoltaic board. There is therefore a need to solve the above-mentioned technical problems.

In addition, in partially remote areas, there is currently no grid supply, and there is a particular need for energy devices that can sustain the supply of electrical energy sustainably. Therefore, it is necessary to develop an autonomous energy device which can adapt to different environments, different regions and different climates at home and abroad, flexibly and comprehensively utilize natural energy sources such as solar energy, wind energy and water energy, and can realize high-efficiency energy conversion, power generation by a generator and electric energy storage and use.
