gather information about solar light ,solar water heating system and solar cooker
Answers
Solar Light: This functions by absorbing the light energy of sun during the day time and then converting it into electrical energy during the night time when the light energy is not available .Most commonly the street lights are the best example of solar light .These lights are made up of photovoltaic cell which converts light into electrical energy by the help of solar battery
Solar Water Heating System: This is used to convert the light energy of sun into heat energy using a solar thermal collector .A sun facing system is is fixed and when the fluid reaches it is stored in it for some time and can be used later.
Solar cooker: This device is used to cook food or pasteurise drink and other food materials by converting the solar energy into heat energy .
The common principle that works behind all these three different machines is that they all use solar light or sun rays to get charged and this acts as the main mode of a resource.
Explanation:
- A solar water heating system, solar light, and solar cooker: all operate with the use of solar energy. The first heats water using sunlight, the second light up the spaces using sunlight and the third cooks food using sunlight.
- Panels are present in all these three machines which absorb the solar rays and recharge the batteries, and then the machines can use these to run.
- The only issue is, solar cooker works very slowly and hence takes considerable time. It is the same for solar-powered heating systems.
- Solar lights will only shine bright if the batteries are fully charged with the help of high-intensity sunrays.
