Renewable energy is an energy source that is naturally available and can be utilized continuously. This is in line with information from the International Energy Agency (IEA) which also states that renewable energy is energy that comes from natural processes that are continuously renewed. The term renewable energy was born as a solution to the limited potential of non-renewable energy sources that are widely used today. Apart from that, the research results also show that the use of non-renewable energy, also known as fossil energy, in the long term also has negative impacts. One renewable energy is solar thermal energy using solar cells or solar panel modules. The subject to be researched is the smart portal at the Datuk Bandar Timur Police Station which uses a voltage supply sourced from the sun or solar panels, so that if there is a power outage, besides that, sometimes the electric current often breaks, so that the operational electrical load becomes weak, this is proven by the lights which is dim so it needs to be subsidized by solar panels and additional batteries so that the door portal can also be actively opened. Apart from subsidizing the electric voltage at the door portal, this research also focuses on reading the incoming voltage and outgoing voltage parameters with an Arduino microcontroller. The tool system design also applies the internet of thought (IOT) concept where the monitoring system will be connected to the telegram system, and if there is a voltage drop (lack of voltage) on the battery, the tool design system will send a message via the telegram device design, in addition to the voltage drop, the incoming voltage , the output voltage as well as the temperature and degree of solar radiation will be sent via telegram, so that the system can be read remotely.
