What is solar insulation?
Solar insulation is a measure of the amount of solar energy reaching a surface or radiation on a given surface over time. The surface in question can be exposed to sunlight, from a particular object or placement on Earth to small space objects such as artificial satellites to the surface of the planet. The Sun cliff of the particular area of the Earth depends on its distance from the equator, its weather conditions and the daily time of the day and the year. It is essential for the continued existence of life on Earth, because the plants rely on the energy of the Sun to survive, and also that it is an important factor in the construction and location of the solar energy.
usually measured in watts per square meter per day. Watt is a standard metric unit of energy or energy over time; One watt of power equals one jouleenergy per second. Kilowatthodines, the term most commonly used with reference to the production of electricity, is enough energy to create a production of 1,000watts for one hour or 3,600,000 joules (3.6 megajoules).
The directly the surface is directed, the higher its solar insulation. Maximum solar insulation is produced when the sunlight hits an angle of 90 degrees. Neolations decrease, as the angle decreases because the bottom angle spreads the same amount of radiant energy to the wider areas. Therefore, the area around the Earth equator that receives the most direct sunlight, the warmest part of the Earth and the polar regions are the coldest. It also causes a changing period because the tilted Earth's axis means that the angle of sunlight reaching a given part of the planet will change during the year. Therefore, the temperature on a given day of Wilmam tends to culminate around the sun's noon when the sun is at the highest point in the sky, and then decreases when the sun falls closer to the horizon later on the day.
Total solar insulation of the outer atmosphere of the Earth from direct sunlight diarrheaIt is of about 1,366 watts per square meter at an angle of 90 degrees during the year, most of which are in the form of visible light. Sunlight attenuation, when it passes through the atmosphere, reduces to about 1,000 watts per square meter at an angle of 90 degrees at the time it reaches the Earth's surface. This character is constantly decreasing as one moves to higher latitudes and decreases from solar noon at the time of the day and drops almost nothing at night. The average insulation of the Earth as a whole during the year is approximately 250 watts per square meter.
areas in similar latitudes may still have significant differences in average postponement due to local factors. Neosolation of the area may be furrier with atmospheric conditions that disrupt sunlight, such as clouds or atmospheric haze. Neosolation rises at higher altitudes, because there is a smaller atmosphere for passing sunlight and be weakened. Measurement of the amount of sunlight in different places can be set upt to create a specialized map called non -adapter map.
The creator of the solar energy is strongly relying on the quorum. The arid or semiarid areas are commonly home to solar power plants to minimize interference with sunlight caused by a cloud and are built at higher altitudes, if possible. Photovoltaic solar panels are mounted at the angles for the incoming sunlight as close as possible to an angle of 90 degrees to maximize the energy received. The optimal angle for this varies according to the geographical location and the season.
The insolation of the area can also be used in designing buildings. For example, the large window of the side of the building facing the equator will release more light and heat during the winter when the sun is low in the sky, and relatively less when it is high in the sky during the summer. This alleviates the extremes of seasonal temperatures inside the building, making it more convenient to reduce the amount of energy needed for heating or air conditioning.
