Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core technology?Photovoltaic (PV) cells converting solar radiation into DC electricity
2. What is the energy management system?Charge controller for regulating battery charging and discharging cycles
3. What are solar street lights?Solar street lights are special street lamps that use sunlight to power themselves. They shine bright lights at night without needing a power line.
4. How do solar street lights get their power?Solar panels on the pole catch sunlight and turn it into electricity. That electricity charges a battery, which then powers the LED light.

Photovoltaic Effect: The generation of voltage and electric current in a material upon exposure to light.
Charge Controller: An electronic device that regulates the voltage and current from the solar panels to the battery.
Grid Independence: The ability of a system to operate without being connected to the public electricity network.
IoT (Internet of Things): A network of physical devices embedded with sensors and software that connect and exchange data.
