Low Maintenance

Solar panels have few moving parts, requiring minimal maintenance. They may only need cleaning occasionally to remove dust or dirt.

Energy Transformation

Solar panels convert sunlight directly into electricity using photovoltaic cells, which are like devices that turn sunlight into power.

Storing Solar Energy

Solar batteries store the energy generated by solar panels during the day for use at night or when sunlight is limited.

Eco-Friendly

Solar energy is clean and environmentally friendly as it doesn't produce harmful pollution like burning fossil fuels do.
