The sun produces a lot of energy every year. We call it solar energy. For us, there will be an inexhaustible supply of solar energy during the remaining five million years of the sun’s life. Solar panels are made up of solar cells that convert solar energy from sunlight into electricity. Because solar cells can generate electricity directly from sunlight, it is the most reliable power generation technology we have now, which is why rooftop solar panel are widely used.
Rooftop solar panels are made up of silicon atoms. Every atom of silicon contains tiny, lightweight electrons, which carry a faint electric charge. When sunlight hits a solar panel, it hits one of the electrons and knocks it out of its orbit. These hit electrons are free to move about, but the cell is designed so that the electrons can only move in one direction, toward the sun. So when sunlight falls on a solar cell, many of the electrons are thrown out of their orbits and become free electrons. Because of the nature of solar cells, the electrons can only move upwards, creating a current that can drive a household appliance.
Rooftop solar panel is the assembly of a number of solar cells, is the core part of the solar power generation system, is also the most important part of the solar power generation system. The features and advantages of solar panel:
- High conversion rate, high efficiency output.
- Excellent low light effect.
- The unique technology makes the components beautiful, strong and weather-resistant, easy to install.
- Solar panels are applicable to a wide range of fields.
- Resources saving, electricity saving and energy saving, simple operation.
Using solar energy helps reduce greenhouse gas emissions that damage the planet. Solar energy is cheap compared to other energy sources and will get cheaper. If we use more solar energy, we can accelerate the reduction of traditional energy use that hurts the planet.
