Detailed ways

In the embodiment shown in Figure 2, the embodiment of a single solar cell panel is sectioned, and the solar (photovoltaic) cell panel (1) converts light energy into electrical energy (i.e. power generation) under sunlight, and supplies electricity to the storage battery (2) ) charging, but sequentially collect the direct current generated by each solar (photovoltaic) panel in the whole system and input it into the inverter (3) to convert it into alternating current output 110V 60HZ, 220V 50HZ or other output power, different output is selected by switch control.

In Figure 1, solar (photovoltaic) components are composed of monocrystalline silicon, polycrystalline silicon solar (photovoltaic) panels and photovoltaic controllers placed on the back, and connected as power generation components, placed in the sun to generate electricity, through which The photovoltaic controller on the back charges the storage battery. Usually, the voltage of solar (photovoltaic) panels converting light energy into electrical energy is 36V, so this voltage is safe. Solar photovoltaic panels can be composed of several panels to form a wheeled positioning mobile frame, such as every 2 or 4 panels to form a wheeled positioning mobile frame with a slope in line with the light, or it can be installed in the form of a fixed type or a sun tracker. Composition, but it must be installed in a place where it can be directly exposed to sunlight.

In Figure 2, the storage battery adopts a battery with a relatively long service life, such as a colloidal battery, and the voltage of a single battery is 12V. cloudy, snowy) power supply. Along with science and technology development will adopt more advanced accumulator, can provide more electric energy when there is no sunlight, accumulator (group) is installed in a accumulator box with positioning pulley, so it can be placed indoors.

In Figure 3, the inverter is converted into electricity, such as 110V/60HZ, 220V/50HZ, etc., and is intelligently controlled by the computer in Figure 4 (or without a computer), and the output power can be directly supplied to Figure 5. Lighting, 6. Household appliances, 7. Office equipment, 8. Industrial electricity, 9. Electricity for public facilities, charging (such as mobile phones, etc.) and other electricity (such as field operations, military purposes), etc., and the remaining electricity can also be incorporated into the country Power grid, but when the power generation of this system is not enough, it can automatically switch to the national grid system for power supply. The inverter is divided into grid-connected and off-grid, and is equipped with easy-to-move positioning pulleys, which can be placed indoors where it is easy to operate.

If the user's local conditions are ripe, the system can omit the battery, and the electricity generated by the solar (photovoltaic) module can be directly input into the grid-connected inverter, and output into the national grid where it is located.
