Gather information about solar light, solar water heating system and solar cooker.
Hint:Solar energy is sunlight and heat captured through a range of continually advancing technologies such as photovoltaic systems, solar heating, solar thermal power, molten salt power plants, solar architecture, and artificial photosynthesis.
Complete Answer:
Solar power is derived from the sun and converted into electrical or thermal energy. It stands as the cleanest and most widely accessible form of renewable energy. Solar technologies harness this energy for various purposes, including generating electricity, providing natural light or comfortable interiors, and heating water for residential, commercial, or industrial needs.
A solar lamp, also known as a solar light or solar lantern, is a lighting device that includes an LED lamp, solar panel, battery, charge controller, and inverter. The lamp operates on batteries charged through a photovoltaic solar panel. Solar-powered home lighting can complement other light sources like candles or kerosene lamps. Solar lamps have lower upkeep costs than kerosene lamps since sunlight, unlike fuel, is free and renewable. Furthermore, unlike kerosene lamps, solar lamps do not emit indoor air pollutants. However, solar lamps often come with higher initial costs and are dependent on weather conditions.
Solar water heating (SWH) is the process of transforming sunlight into heat energy to warm water through a solar thermal collector. There are several SWH system designs available, with varying costs to suit different climates and locations. SWH systems are frequently used in homes and some commercial settings. A sun-facing collector heats a fluid that flows through a storage tank, keeping the water warm for future use. SWH systems may be active (requiring a pump) or passive (relying on natural convection). They may heat only water or both water and another working fluid, directly or via light-concentrating mirrors, and can function as standalone units or as hybrids alongside electric or gas water heaters.
A solar cooker is a device that uses direct sunlight to cook, heat, or pasteurize food and beverages. Many solar cookers are simple, low-tech devices, though some have the power and sophistication comparable to conventional stoves. Large solar cookers can prepare food for large groups. Because solar cookers operate without electricity and are cost-effective, several non-profit organizations promote their use worldwide to reduce fuel costs and air pollution and help curb deforestation and desertification.
Note: Solar energy is a vital renewable resource, with technologies classified as either passive or active, depending on their methods for collecting, storing, or converting solar energy into usable forms.
