The important of solar energy, benefits can you get using solar energy, how is the process using the solar panels to produce energy and list the advantage and the disadvantage of it.

Answer 1

Importance of Solar Energy:-

All life on earth is supported by the sun. This amazing resource radiates energy and provides us both heat and light by fusing hydrogen into helium at its core. We call this solar radiation. Only about half of this solar radiation makes it to the Earth’s surface. The rest is either absorbed or reflected by clouds and the atmosphere.solar energy can be used directly for heating and lighting homes and businesses, for generating electricity, and for hot water heating, solar cooling, and a variety of other commercial and industrial uses.

there are two main types of solar energy technologies—photovoltaic (PV) and concentrating solar power (CSP).

photovoltaic (PV):- When the sun shines onto one of those solar panels, photons from the sunlight are absorbed by the cells in the panel, which creates an electric field across the layers and causes electricity to flow. PV installations may be ground-mounted, rooftop-mounted or wall-mounted. They may be mounted in a permanent orientation to maximize production and value or they may be mounted on trackers that follow the sun across the sky.

concentrating solar power (CSP):-t is used primarily in very large power plants and is not appropriate for residential use. This technology uses mirrors to reflect and concentrate sunlight onto receivers that collect solar energy and convert it to heat. The heat is used to drive a heat engine, usually a steam turbine, that is connected to an electrical power generator which is then used to produce electricity.

How Does Solar Energy Work?

The first and most basic concept to understand relative to solar energy is the simplicity of how it works. Basically, solar energy is produced by capturing radiant light and heat from the sun and then converting it into energy that can be used to power homes, businesses, tools, and machinery. Electricity is generated during peak periods — hot afternoons — when the demand is highest and air conditioners are going full blast. But solar energy can be stored for later use such as on highways where the sun’s energy is captured during the day to enable highway signs to shine at night. There are different kinds of systems that can be designed to collect and store solar energy but the most common installation is known as an active solar power system. An active system uses a mechanism, such as the solar panels one sees on a roof, to capture sunlight and generate power. Solar panels are made up of photovoltaic (PV) cells that capture sunlight particles called photons. Using a semiconducting material such as silicon, the PV cells then convert the photons into useable direct current (DC) electricity. NAn inverter connected by wires to the panels turns those direct currents (DC) into alternating current (AC) electricity and sends it to the breaker box panel in your home or business to power your lights, computers and other appliances.
