Solar Power System
What is a solar power system?
The sun is an indispensable natural resource for mankind, and it is inexhaustible and inexhaustible. The solar power system is the principle of converting solar radiation energy received by the earth’s surface into electrical energy. A solar energy system is a power generation system that connects solar photovoltaic modules, controllers, batteries, and loads. There are two main types of solar power systems: on grid and off grid solar system. Off grid solar system makes it independent from the public grid.
When there is a large amount of power generation, the surplus electric energy can be stored in the battery of off grid photovoltaic system, and it can be supplied to the load on rainy days or when there is no light. The on-grid solar power system does not store energy by the battery and directly inputs the electric energy into the public grid through the grid-connected inverter. When the system generates insufficient power due to rainy days and other reasons, the grid supplies power to the load.
The composition of solar panel system
The solar panel system consists of solar battery packs, solar controllers, and storage batteries (groups).
A solar panel is the core part of the solar power system and the most valuable part of the solar power system. Its function is to convert the sun’s radiant power into electric energy, or send it to the storage battery for storage, or drive the load to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system.
The function of the solar controller is to control the working status of the entire solar pv systems and to protect the battery from overcharging and over-discharging. In places with large temperature differences, a qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch and time control switch should be optional options of the controller.
The batteries used in solar panel battery systems are generally lead-acid batteries. In small and micro systems, nickel-hydrogen batteries, nickel-cadmium batteries, or lithium batteries can also be used.
On many occasions, an AC power supply is required. Because the direct output of solar energy is generally. In order to provide electrical energy to the electrical appliances, it is necessary to convert the DC electrical energy generated by the solar energy system into AC electrical energy, so an inverter is required. On some occasions, when multiple voltage loads are required, inverters are also used.
The characteristics of solar energy system
The solar battery of the solar panel battery system can be installed on the roof and other spaces that are not normally used. It is noiseless and has a long life. Once the installation is completed, there is almost no need to adjust.
Now, as long as the roof is filled with solar cells, the self-sufficiency of electricity in the home can be achieved. Nowadays, the main use of solar energy is no longer small-scale, but professional in nature. It has played an important role from the military field, the communications field to the urban construction field.
