How Solar Energy is Converted Into Electricity

Solar energy is the most abundant and cleanest source of energy available to us, but we still need to put a lot of work into converting it into energy we can use. Most solar power systems are designed to be used with solar cells, which are the most basic and popular way of converting solar energy into electricity. Other systems used to store energy come in more elaborate designs that can store more energy and run on clean sources of fuel such as the sun or natural gas. The diagram below shows the basic process of how solar energy is converted into electricity:

The Basics of Solar Cell Technology

A solar cell is a device that can convert solar energy into electricity. Solar cells are usually made of silicon or gallium arsenide, which are both abundant on Earth. These are the most common materials used to create solar cells because they are relatively easy to process into thin films, which enable them to capture more solar energy. Films made of these materials are also very stable, so they don’t degrade over time like some other types of cells do. These are the most fundamental and important concepts for understanding solar cell technology. If you’re interested in learning more, you can click on the links below:

The History of Solar Cell Technology

The history of solar cell technology is actually rather interesting because it goes back to the 1950s, when researchers in Europe and North America first started investigating how to efficiently convert solar energy into electricity. In the 1950s, large-scale solar power systems were first used in regions such as the southwestern United States, where the sunny weather and large amounts of land made it an ideal place for such systems. In the 1960s, the power of solar cells was enhanced when gallium arsenide, a more plentiful and efficient source of energy, was used to create the cells. Around this time, the use of solar cells grew considerably, and by the end of the decade, they were common in spacecraft. These early years were an important period in the history of solar cell technology because it laid the groundwork for what would become one of the dominant forms of energy generation today: solar power.

How Solar Power Systems Work

If you’ve ever been in an astronomy or astrophysics class, you may have learned about how our solar system works. The sun provides the energy that enables life on Earth to exist, so it’s only natural that we would want to harness it for our own use. The basic principle behind a solar power system is quite simple: the more sunlight that is focused on a given area, the more electricity that can be generated. This happens because the amount of energy that is in sunlight is actually quite large, and more importantly, it’s constantly changing and moving as the sun sets and rises. This is why concentrating sunlight using lenses or mirrors is so important: by focusing sunlight into a small area, a much larger amount of energy can be converted into electrical energy than would otherwise be the case. You can use a lens to focus sunlight on a solar cell or a mirror to focus sunlight on a point, like a tower. The diagram below shows you the basic concept behind why solar power is efficient:

The Rise of Solar Power

Although solar power has been around for a long time, it really started gaining momentum in the early 2010s, which you can see in the timeline below. By 2015, the use of solar power had increased by 23% due to the large amounts of sun that were shining and the increasing prices of fossil fuels. This was largely because of the increased popularity of green energy amongst the public and businesses as a whole. The year 2015 was also the inception of the modern day grid-connected solar system, which enabled even more people to buy into the green energy movement. The modern day solar system enables homeowners and businesses to generate their own electricity using photovoltaic cells without having to build a large power plant. Your solar cells are connected to the grid, and when sunlight is shining, you will have electricity immediately available to you. The rise of solar power is continuing today, and more people are looking for ways to reduce their energy consumption, protect the environment, and be more independent.

The Impending Rise of Renewable Energy

For many years, there has been talk of a coming “energy crisis,” and the world’s most prominent scientists have issued warnings about the impending world energy shortage. It’s no secret that we are running out of fossil fuels, and despite all our efforts to find alternative fuels, the truth is that we are still reliant on them for our energy needs. This is mainly because it is extremely difficult and expensive to find enough quantities of liquid and gaseous fuels to satisfy our energy demands. Scientists have suggested that this is why we are experiencing an increase in global temperatures and they predict that this trend will continue and eventually lead to the end of human life as we know it. The only solution to this problem is to switch to renewable energy sources that can be produced in large quantities and do not destroy the environment when used. The most prominent of these renewable sources are the sun, the Earth, and hydropower, which we will discuss below.

Hydropower

Hydropower is one of the most prominent renewable energy sources available to us, and it’s also probably the easiest to understand and implement. The process of hydropower involves using water to generate electricity, and the most common and efficient way to do this is called the “flow-through turbine”. Think of a bicycle outfitted with a generator that runs on water or oil. This is essentially what a hydropower plant looks like:

The Sun

The sun is another prominent and easy-to-implement renewable energy source, and it’s been around for a long time. What is more, it is the most abundant and constant source of energy available to us, which means we will likely never run out of it. The sun provides enough energy to satisfy the world’s demand for electricity, though it takes approximately a year and a half for the Earth to spin completely once relative to the Sun. The sun is also essential to life on Earth, as it provides the energy that enables us to grow food and fuel, which is why it is vital to protect it. The only problem with the sun is that we cannot use it directly for heating purposes, as the direct heat from the sun can be extremely dangerous when used improperly. Despite this, the use of the sun’s energy continues to grow, and it is predicted that in the near future, nearly every home and business will have some sort of a solar power system.

The Future of Solar Energy

The future of solar energy is incredibly bright, and it continues to gain momentum every year. There are already a variety of ways that the sun is used to generate electricity, and new innovations are being implemented all the time. In addition to the sun, we’ve discussed hydropower, which is a very stable and prominent form of renewable energy. Another prominent source of renewable energy is the wind, which has the advantage of being very plentiful and constant, though not all regions are well suited for wind farms. These are just two of the most prominent forms of renewable energy, and there are many more that can be used to produce electricity.

Where Can I Buy Solar Panels?

One of the best places to start if you’re interested in buying solar panels is online. The majority of online stores will have all the necessary information you need to choose the correct sized solar panels for your needs as well as how many you need overall. You can also find many third-party resources that can help you compare different products and their respective perks and flaws. Once you’ve found a reputable source, you can rest assured that you’re purchasing a quality product and that you’re not going to be shortchanged by any means.

Final Takeaway

There is no question that solar energy is the most promising and abundant source of energy available to us. We’ve discussed a variety of ways in which this energy can be used, and it’s clear that we have a long way to go before we can fully implement it into our daily lives. However, as more and more people are realizing the advantages of solar power, the price of solar cells has come down and will continue to do so, ensuring that everyone can afford to have their own little slice of paradise on the roof.
