1. Solar cell module
A solar cell can only generate a voltage of approximately 0.5V, which is much lower than the actual required voltage for use. To meet the needs of practical applications, it is necessary to connect solar cells into components. The solar cell module contains a certain number of solar cells, which are connected through wires. The number of solar cells on a module is 36, which means that a solar module can generate approximately 17V of voltage.
The physical units sealed by solar cells connected by wires are called solar cell modules, which have certain anti-corrosion, wind, hail, and rain resistance capabilities and are widely used in various fields and systems. When the application field requires high voltage and current, but a single component cannot meet the requirements, multiple components can be formed into a solar cell array to obtain the required voltage and current.
2. DC/AC inverter
A device that converts direct current into alternating current. Due to the fact that solar cells emit direct current, while the general load is AC load, inverters are indispensable. Inverters can be divided into independent operating inverters and grid connected inverters according to their operation mode. Independent operating inverters are used for solar cell power generation systems that operate independently and provide power to independent loads. The solar cell power generation system used for grid connected operation by grid connected inverters feeds the electricity generated into the grid. Inverters can be further divided into square wave inverters and sine wave inverters based on their output waveform.
3. Design of distribution room
Due to the lack of batteries, solar charge and discharge controllers, and AC/DC distribution systems in the grid connected power generation system, if conditions permit, the inverter of the grid connected power generation system can be placed in the low-voltage distribution room of the grid connected network. Otherwise, a separate 4-6m2 low-voltage distribution room can be built.
