Sunlight not only can make us feel calm and happy on a bright sunny day but can also be put to work to reduce our electricity bills. With constant talk of dwindling resources and serious issues with climate change, it\u2019s no wonder that an increasing number of people are looking for ways to save money, resources, and the environment. One popular method is solar energy.<\/p>\n

Solar panels have become very popular as they offer a handful of benefits such as being an eco-friendly source of energy and a cheaper way of powering your house. Read on to learn about where in the world solar energy is the most popular, how do solar panels work, what are solar panels made up of and much more.<\/p>\n

Understanding of the Topic Solar Energy.<\/h2>\n

Evolution of Solar<\/strong><\/p>\n

In the year 1767, Horace Benedict, a Swiss Scientist invented the world\u2019s first solar collector. The insulated box was constructed out of three layers of glass, designed to absorb heat energy. This mechanism was known as the first solar oven and could reach a temperature of 110 degrees Celsius.<\/p>\n

Next solar energy milestone occurred in the year 1839. French Scientist Edmond Becquerel discovered the Photovoltaic effect by placing an electrode in a conductive solution. As soon as the electrode was exposed to sunlight, a current was generated.<\/p>\n

It was in 1950s, Bell Laboratories produced the very first silicon solar cell- an electrical device that converts the energy of light directly into electricity via the photovoltaic effect. Assemblies of solar cells are now used to make solar modules, which generate electrical power from sunlight for residential and commercial buildings.<\/p>\n

How do Solar Panels work?<\/strong><\/p>\n

When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a circuit, they generate electricity. Multiple cells make up a solar panel and multiple panels can be wired together to form a solar array. The more panels you can deploy, the more energy you can expect to generate.<\/p>\n

Solar panels work best when they are installed pointing directly at the sun, and in a position where nothing is blocking them. The weather will also play an important part on the effectiveness of the panels.<\/p>\n

What are solar panels made of?<\/strong><\/p>\n

Photovoltaic solar panels are made up of many solar cells. Solar cells are made of silicon like semiconductors. They are constructed with a positive layer and a negative layer, which together creates an electric field, just like in a battery.<\/p>\n
