What is Solar Energy?

Solar energy is the energy that comes from the sun, which is a giant ball of gas that is 93 million miles away from Earth. The sun's energy is what makes life on Earth possible.The sun produces energy through nuclear fusion. This is a process where hydrogen atoms are fused together to form helium atoms. This process releases a tremendous amount of energy.

The Earth gets its energy from the sun in the form of electromagnetic radiation. The electromagnetic radiation that reaches the Earth is in the form of visible light, infrared light, and ultraviolet light.The visible light we see makes up only a small part of the sun's electromagnetic radiation. The infrared light and ultraviolet light are invisible to our eyes, but they can be felt as heat.The infrared light and ultraviolet light that reach the Earth are absorbed by green plants and converted into chemical energy that can be used by animals and humans for food and warmth.

How Solar Energy Works?

Solar panels are made of photovoltaic cells, which are special types of electronic devices that produce electricity when exposed to sunlight. A photovoltaic cell has two layers: a layer of positively charged "holes" and a layer of negatively charged electrons. When sunlight hits the cell, it knocks some electrons loose from their atoms and allows them to flow freely between the two layers of the cell. This flow of electrons produces electricity that can be used to power appliances or charge batteries.

How much electricity solar panels produce depends on how much sunlight they receive, which varies depending on where you live. Solar panels produce more electricity when they are facing directly toward the sun, so they should be mounted at an angle that allows them to follow the sun's path across the sky during the day.

Solar panels are connected to an inverter, which converts the direct current (DC) electricity produced by the panels into alternating current (AC) electricity. This electricity can be used to power appliances, charge batteries, or send electricity back to the utility grid.

How much solar energy is available?

The amount of solar energy available for use depends on where you live. The amount of sunlight available in the U.S. is much greater than the amount of electricity needed to power our homes and businesses. On average, there is enough solar energy in one hour to meet the nation's entire energy needs for one year.

How much does it cost to install solar panels?

The cost of installing solar panels depends on many factors, including your location, local labor rates, and the size of your home's roof. The cost also depends on whether you are installing a system yourself or hiring a contractor to do it for you. If you are installing a system yourself, you will need to purchase the panels and other equipment. The cost of this equipment will depend on your location and the size of your system. You can get an idea of how much you might spend by using the EnergySage Solar Calculator. This calculator will give you an estimate based on information you provide about your location and the size of your home's roof. It will also tell you how much you can save over 20 years by installing a solar system instead of purchasing electricity from your utility company.

Conclusion

Sunlight is considered to be "renewable" because it will last for millions of years before it runs out. Also it does not harm environment in any ways.
