Explanation:
Solar power is the energy from the sun that is transformed to electrical or thermal or energy. It is the cleanest and most available source of renewable energy. Solar technology may use this energy for a range of applications, including producing power, supplying light or comfortable interiors, and heating water for residential, commercial or industrial use.
A solar lamp also named as a solar light or a solar lantern is an illumination device consisting of an LED lamp, a solar panel, battery, a charge controller and an inverter. The lamp is powered by batteries, charged by the use of a solar photovoltaic screen. Solar-powered household lighting can supplement other light sources such as candles or kerosene lamps. Solar lamps have lower maintenance costs than kerosene lamps because, unlike fuel, renewable energy from the sun is free. In comparison, solar lamps emit no indoor air emissions other than kerosene lamps. However, solar lamps typically have higher initial costs and are weather-dependent.
Solar water heating (SWH) is the transformation of sunlight to heat for water heating by means of a solar thermal collector. A number of configurations are available at variable cost to offer solutions in diverse latitudes and climates. SWHs are commonly used in residential and some commercial applications. The sun-facing collector heats up the operating fluid that flows through the collection tank for later use. SWH is active (pumped) and passive (convection-driven). They use just water, or both the water and the working solvent. They are heated directly or by light-concentrating mirrors. They work independently or as hybrids of electric or gas heaters.
A solar cooker is a system that uses direct sunlight energy to cover, prepare or pasteurize beverages and other food materials. Many of the solar cookers currently in use are relatively affordable, low-tech machines, but some are as powerful or as costly as conventional stoves, and sophisticated, large-scale solar cookers can be used to cook for hundreds of people. Since they use no electricity and cost little to run, several non-profit groups are encouraging their use around the world to help mitigate fuel prices and air emissions and also slow down deforestation and desertification.
Note:Solar energy is an important source of renewable energy, and its technologies are generally described as either passive solar or active solar energy, based on how they collect and transmit or transform solar energy into solar energy.
