Solar APIs and Their Working Principle

Solar API refers to the interface that methodically interacts with solar technologies. The solar API sends the information about the data that the user wants to get on the smartphone. This information is then received by the sensors and solar systems. Once the sensors gather the relevant data, they send it back to the mobile application with the help of APIs. 

API plays a significant role in communicating real-time data in a format that users can understand. The sensors in the solar panel can measure the temperature. Similarly, the power stored in batteries is also known to the inverter. All this real-time information, when communicated through a medium to the mobile application, it is called the solar API.
