The main component is the solar panel. which will serve to receive sunlight for use in generating direct current koiusa electricity Inverters are responsible for converting direct current from solar panels into alternating current for use with household appliances.
Solar Cell โซล่าเซลล์ Panel
solar panel It is an invention that can change solar energy. There are many types of usable electrical energy, the most popular type being Silicon Semiconductor, which absorbs the energy from sunlight and converts the energy into DC electricity, divided into 3 types. is
– Monocrystalline Silicon Solar Cells
– Polycrystalline Silicon Solar Cells
– Thin Film Solar Cells
which can be used the same but has the ability to generate electricity that is different in Thailand, it is commonly used with solar cells โซล่าเซลล์ Monocrystalline Because it is the type that can produce the best electricity and lasts up to 25 years. You can read more articles on solar panels.
Inverter
Inverter is a type of electrical device. used for converting direct current to alternating current The electricity obtained from the solar panel will be direct current. And will pass to Inverter Inverter is detectmind responsible for converting direct current to alternating current. Can be divided into 2 types:
– Model used with Stand-Alone System
– Grid-Tied Inverter is used with systems that work in relation to electricity (On-grid System).
There are different uses. The type used with the stand-alone system (Stand-Alone System) will be used with the installation of off-grid solar cells or the type that stores the power in the battery, but the Grid-Tied Inverter will Used with the installation of solar cells with On-grid systems, which can be read more in the solar panel article.
Solar Charge Controller
It is a solar cell battery charge controller. which will charge the battery requires a battery charge controller Because if the solar cell system is connected directly to the battery There will be a voltage that pushes between the voltage of the solar cell and the voltage of the battery. The battery charge controller must be compatible with the selected system voltage.
Battery
Is a body that will help store electrical energy When the battery is put into operation, the discharge current will be a DC voltage. But if you want it to become an alternating current voltage that is used by the residence. An inverter must be installed to convert the DC voltage to AC. There are many different types of batteries today. must be selected to suit the type of use for the battery used Recommended as a battery that is for backing up electricity. (Stationary/Standby Battery) This battery has a power storage page for emergency use in case of power outages, blackouts and surges, etc.
Dc/Ac electrical equipment
It is an electrical device intended for the connection between DC, direct current and AC, alternating current. in the solar cell installation system so that the system is complete and can be used effectively
How many solar cell systems are there and how do they work differently?
The current installation of solar cell systems can be divided into 3 main systems together. To be suitable for the form of use and suitable for the installation area as follows
On Grid System On Grid
On Grid System On Grid : It is a solar cell system that uses both electricity from electricity. and electricity produced from solar panels Suitable for residential houses that use electricity during the daytime. This system does not have a battery to back up power. Electricity can be generated and ready to use. Before installing this solar cell system must first ask for permission from the electricity authority. At present, this system is the most popular.
Off-Grid Off-Grid System
Off-Grid Off-Grid : It is a solar cell system that is not connected to electricity. There will be electricity generated and ready to use immediately during the day. And the rest will be backed up in the battery for use at night. (also known as Stand Alone system) does not require permission from the Electricity Authority Installation with this system is suitable for places where electricity cannot reach such as remote areas on high mountains.
Hybrid system
Hybrid system Hybrid : It is a mix between Off Grid and On Grid systems, which is connected to electricity from electricity. together with the use of electricity produced from solar panels and power from the battery In the event that the solar panel generates more electricity than it can use, the electricity is sent to the battery. and can be used during the night But the hybrid system will not be able to sell electricity to the government. It also has a very high installation price, so it’s not very popular.
