What You Should Know About An Off-Grid Solar System For Remote Areas

A solar cell is an electronic device that converts solar energy into electrical energy. The solar cells that we use in general household buildings are on-grid solar cells that must work with the electricity supply. But imagine remote areas where electricity may not be accessible, such as areas on islands, mountains, or mountains, as well as agricultural areas where electricity is used very far from transmission towers. This causes us to use off-grid solar cells because they do not have to be connected to the distribution system of the Metropolitan Electricity Authority or the Provincial Electricity Authority, but can be connected directly to electricity from the solar panels. Including a battery that can store electricity for use in emergencies. So don't wait. Let's get to know more about off-grid solar cell systems!

How Off-Grid Solar Cells Work

Off-Grid solar cells work by converting solar energy into electricity. Then store that energy in the battery. Then the electrical energy stored in the battery will be used. Normally, Off Grid solar cells support only direct current (DC), but because most of the electrical appliances in our home use alternating current (AC). Therefore, if you want it to be fully usable, you must rely on an inverter to act as a medium for converting electricity. Which has both batteries to store electricity for us to use in emergencies and without having to connect to electricity from the electricity company. Therefore making it suitable for remote locations because it is a Stand Alone system that can produce its own energy.

What does an Off-Grid solar cell system consist of?

Solar panels: produce electricity.
Controller: Responsible for adjusting the voltage regularly before sending power to store in the battery.
Battery: serves to store electricity for use at night or in emergencies.
Inverter: Responsible for changing the direct electric current from solar panels. to alternating current to supply various electrical appliances within the home

Advantages of off-grid solar cell systems

There is no monthly electricity bill that must be paid to the Electricity Authority.
The off-grid system means that we are not damaged by power outages or outages.
The off-grid system is not connected to electricity from the electricity authority. Therefore, there is no need to request permission from the electricity authority and related agencies.

Considerations for off-grid solar cell systems

There are relatively high installation and maintenance costs. Because there are more tools and accessories for installing the system than other systems.
If it rains for several days in a row or there is no sunlight for several days in a row. The energy stored in the battery may be depleted.

Things to know if installing Off-Grid solar cells

Off-grid solar cells support direct current (DC). This means that if your appliances are direct current, It can be connected to use with the device without having to connect through an inverter. But if your electrical appliances are alternating current, they need to be connected through an inverter.
Inverters of on-grid and off-grid systems are different.
- The on-grid system uses a Grid Tie Inverter: It is a device that converts electricity to use with home appliances and can be connected to the electricity grid system.
- The off-grid system uses an Off Grid Inverter: converts electricity from direct current to alternating current but cannot be connected to the electricity grid system.
Taking direct electricity from solar panels and storing it in batteries. We can choose whether to supply power to devices that use direct or alternating electricity.
An off-grid system is a system that is produced for own use or if production exceeds It will be stored in the battery system instead. Cannot be resold like on-grid systems
