Solar panels generate electricity by relying on sunlight, so they don't need to be heated, as long as there is light.
Your question may be: When the solar panels are baking under the hot sun, will it still produce electricity when it reaches 80 degrees?
If so: the solar panel still has electrical energy output, but it is less than the electrical energy at 25 degrees. of the panel will be based on It decreases as the temperature increases. For details, please refer to the temperature coefficient provided by the solar panel supplier.
Solar panels can directly convert thermal energy into electrical energy.
Solar power generation methods There are two solar power generation methods: one is the light-heat-electricity conversion method and the other is the say conversion method.light-electricity side.
1. The light-heat-electricity conversion method uses thermal energy generated by solar radiation to produce electricity. Generally, a solar collector converts the absorbed thermal energy into steam as the working fluid, and then drives a working fluid. steam turbine to produce electricity. The first process is a process of converting light into heat; the second process is a process of converting heat into electricity.
2. The direct light-to-electricity conversion method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for converting light into electricity is the solar cell.
Monocrystalline silicon solar panels:
The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, the highest atteing 24%. This is the highest photoelectric conversion efficiency among all types. of solar panels. The most effective, but the production cost is so high that it cannot be widely and commonly used in large quantities.
Since monocrystalline silicon is usually encapsulated in tempered glass and waterproof resin, it is strong and durable, with a lifespan of typically up to 15 years and up to 25 years.
