Solar Cell Components, The panels are the visible part of the solar cell, as they are arranged in arrays either on the roofs, on the columns, or directly on the ground, regardless of where they are placed, they must be installed well using special holders for them, and at an optimum angle commensurate with The direction of the sun’s rays, so that the solar energy is converted into electricity. 
The battery The solar cell produces electricity during the day during sunrise, which requires a store to store part of the energy that it produces so that it can be used at night, and this is the function of the battery, where it stores the energy produced by the solar cell to be reused at night or even on cloudy days And free of sunlight.
Solar panels produce DC power (abbreviation: DC), while household electrical appliances use AC power, so the function of the inverter is to convert the DC power produced by solar cells into the AC power (abbreviation: AC) required by household appliances. 
Charge Control Device
This device is found in any solar cell system, as it regulates the amount of current fed by the photovoltaic panels into the batteries to charge them. Its main function is to prevent the batteries overcharging, in addition to blocking the battery current from leaking back into the photovoltaic array at night or when it disappears The sun 
The silicon that is used inside solar cells is highly processed, as this material is extracted from silica mines that are often located in areas with a high concentration of quartz so that the silica is refined until it reaches its mineral qualities, although this process takes place inside an arc furnace. However, the material cell remains photoelectric, thus enhancing the amount of energy released by the cell, making it pure. Pure silicon is crystalline, so it is a necessary structure for photovoltaic cells.
