Solar cells or solar cells It is a device that directly converts solar energy into electricity. Its working principle is to use semiconductor materials such as silicon that have special properties in creating an electric charge when exposed to sunlight. Solar cells have the advantage of having no moving components. no noise No greenhouse gas emissions and can be used for up to 20-25 years.

Solar panels or solar panels It is a device used to convert solar energy into electrical energy. Its working principle is to use materials that have semiconductor properties, such as silicon, that can generate electricity when exposed to sunlight. Solar panels The advantage is that there are no greenhouse gas emissions. no noise Don't need a very large space. and does not require much maintenance.

Solar cell system or a system for generating electricity using solar energy Consists of 4 main components:

• Solar Panel, which is a device used to receive sunlight and convert it into direct electricity (DC).
• Charge Controller, which is a device used to control battery charging from solar panels.
• Battery, which is a device used to store electrical energy from solar panels.
• Inverter, which is a device used to convert direct current (DC) to alternating current (AC) for use with household electrical appliances.

Off Grid and On Grid systems are different systems for generating electricity from renewable energy. Off Grid systems are systems that are not connected to the public electricity system. or not receiving power from any agency, such as a solar power system that uses batteries as an important part of storing electricity Suitable for areas without public electricity supply. or there is an unstable power supply.

On Grid system is a system connected to the public electrical system. or receiving power from any agency, such as a solar power system that uses an inverter as an important part in converting electricity Suitable for areas with public electricity supply. To reduce the cost of using electricity.
