Solar energy is a trending, affordable and renewable power source that people use all over the world today. The primary source of solar energy is the sun. We can support this energy through the use of photovoltaic solar panels. The sun is the source of energy received by the earth. This is one reason we can transform solar energy into electricity through the sunrays.
Furthermore, the energy from the sun can light up home appliances, provide power to companies and can serve any power purpose. Solar energy can also serve smaller purposes in some countries such as the production of salt. This is possible through seawater by evaporation. Solar energy meets the world’s power needs of a year, within one hour. Although, we are only able to access 0.001 percent of this energy.
This source of energy is perpetual as long as there is a potential source of sunlight. Also, solar energy if we manage it suitably tends meeting potential energy needs. However, three factors determine the quantity of electricity we generate using solar energy, which are:
- Size of the solar panel.
- The accuracy of the solar cells within the panel
- Amount of Sunray that gets into the solar panel.
The two major types of solar energy are the photovoltaic solar energy and the thermal power solar energy.
The photovoltaic solar energy: This type of solar energy transforms light into power supply through a semiconductor known as silicon. This kind comes from different cells produced by a constant current. The current is then transformed into other currents by an inverter. The photovoltaic energy works mainly with sunlight. Although it works in cloudy weather also, with a reduced volume. This is the commonest way to use solar energy. The generated energy can be used immediately or stored in a solar battery. Photovoltaic solar energy is mostly for residential usage and small scale electricity needs. Unlike the thermal solar energy that is used to produce electricity on a larger scale
The thermal solar power, on the other hand, produces heat at a temperature below 100c. This heat is stored and converted into electricity. We use solar thermal through the process of water heating. This is achieved by placing the panel on the rooftop to absorb sunlight. Thereby, heating the liquid in the cylinder and transmitting it into your chamber for use.
There are so many ways to use thermal solar energy namely,
Reducing temperature solar thermal energy, this is done by climate effect, through the heating and cooling of air. The passive solar building design is an example of this kind of thermal energy. The process works through the entrance of sunlight on a spacious area, and after that closed when it needs to be cooled.
Medium temperature thermal solar, this involves a solar boiling heating process. On the rooftop of your building, the collector captures the heat from the sun. After that, you can transfer the heat via water pipes in your homes. This method is a substitute for the traditional water heater generated by oil and gas.
Intense temperature thermal solar energy. This is used to generate power supply in large quantity, such as a turbines. The technology is referred to as concentrated solar power. It works with a mirror focusing the sunlight with tubes that contain a liquid which can hold heat energy for a longer time. This heated liquid can turn water into steam, which can generate electricity
Solar energy products are fast rising in the market today. Solar energy helps to foster economic growth as well as the environment. Over time, energy needs have been met solely by oil, coal and natural gas. However, recent discoveries about solar cells technology have made it much better than it was several years ago. For this reason, many people are swinging towards solar power today.
As we read on, we will see several benefits of solar energy.
Advantages of solar energy
- Easy regenerated source
This is however regarded to be the best of the pros of solar energy. Continuity is a basic factor associated with any product. As long as the sun sets daily, solar energy will be available to all, even in a billion years to come. Unlike other sources of power, every country of the world can make use of solar energy easily without fear.
- It can meet different power needs
We have many needs that have to do with the use of power, and in this 21st-century, power is crucial for survival. Solar energy can meet our daily diver’s energy needs. Solar energy can also, be used as a good source of power in environments with no access to the energy grid to get good water supply. Also, solar energy can be composed into matters used for building.
- Low functional charges
Another important benefit of using solar energy is that maintenance is not capital intensive. The charges are relatively on the low side. All it entails is keeping it clean always. You can have them cleaned a couple of times in the year by contracting certain cleaning companies, who do it at a minimal fee. It’s difficult for it to wear or tear because there are no detachable parts. The inverter is the only part that you need0 to renew within 5 to 10 years. Another part is to ensure that you maintain the cables for tremendous effect.
- Decreases energy bills
Electricity is a necessity in every home and organization. Without it, so many things will come to a halt, and this would affect our well being. We all know how important electricity is and that’s why many people pay heavily to have sufficient energy supply. The good news is, you can pay less and have as much energy supply as you need with solar energy. The reason being that most of the power needs will be met through solar energy.
- Advanced technology
It is a plus that the solar system technology is advancing rapidly. This will eventually lead to better innovations and packages that would suit our energy needs better. Furthermore, this will mean an increase of solar panels and double effectiveness on electrical advancement on solar energy systems.
- It is not noisy
Silence is one major improvement made by the solar energy system. Imagine working, or being in the comfort of your home with the use of maximum power supply accompanied by silence. Trust me; silence has a way of calming the brain and nerves. Keeping you relaxed and happy as well. Unlike other energy sources that are very loud and extremely noisy. This is why recently, solar energy is used for residences and business purposes.
- Collective usage reduces cost
A group of people can use solar energy within a given geographical location. This will help address the issue of poor shades and inadequate space. The shared solar energy platform is known as community solar gardens. It can give electricity to a community of people without the solar energy panel installed on their rooftops. This will reduce the cost of installation.
- Produces clean energy
How can we survive in the years to come if we breathe in bad air produced by the conventional energy systems? Statistics has it that over 6.4 million people die yearly across the globe because of air pollution. These harmful gases produced by fossil fuels are also harmful to animals, crops, trees, and vegetations. Therefore, Electricity issues are best resolves with a solar energy system. Solar energy produces clean electrical energy that is not harmful to our health. With solar energy, we can live a better life for future generations.
- Long time warranty
Durability is one factor that makes a product stand out. The good news is solar energy panels are tested and designed to withstand major storms of 140 miles per hour. Solar energy cells are protected under shatter proof tempered glass, with the use of a flexible substance. There’s no need to fear, as most manufacturing companies provide a 25-year warranty for their solar panels. Also, manufacturing companies provide a detailed guideline on the maintenance strategy.
- It provides jobs
The production of solar panels by manufacturing companies provides job opportunity. It has proven to be a good source of employment in areas such as sales and installation, research and production. Not only does it create job opportunities, but it is also, an avenue for indefinite economic growth.
- It is quite simple to install
With the availability of either horizontal or vertical space, installation can be done. It is quite easy and less complicated to install a solar energy panel. Although, most manufacturing
Companies offer the services of installation. It would be best if the manufacturing companies are contracted for the installation of solar energy.
- Increases home value.
The worth of any home consist of the quality of items is in the home. Investing in a solar energy panel is one wise way to add value to your home. Most especially if such a home is for sale, it will give your home a touch of class and make potential buyers long for it. Also, it will make you smile to the bank.
Although solar energy is one good and available power supply, it also has some cons that we will discuss shortly.
Disadvantages of solar energy
- Climate condition
Solar systems are mostly functional in sunlight. Although solar power can still function in cloudy weather conditions, its effectiveness is very slow. This means there could be some sort of complications when it's rainy or cloudy. Also on the cons, solar energy cannot function when it’s dark. However, if you want a functional water heating solution at night and when it's rainy, then we recommend thermodynamically.
- Fairly high costs
Buying a solar energy system is cost intensive. Though, there is a systematic plan by the US government for the choice of a renewable energy source, called the feed-in tariff. This entails paying for solar panels, batteries, inverter, wiring, and installation as well. All of this is what makes it expensive. But subsequently, with the new solar technologies on the ground, we believe that the price will be lower.
- Requires large space.
A solar energy plant requires enormous space. The quantity of sunlight you need determines the numbers of panels you need to install. This is a major problem because some rooftops can’t accommodate the necessary panels some houses need. This will equally reduce the volume or determine the electricity you can use in your home. Though it is advisable to store some in your yard also if there would be access to sunlight there.
- Greenhouse Gasses
Greenhouse gasses are air pollution associated with solar energy. During the process of installation, this harmful gas could be emitted. There are equally some hazardous components that come out during the manufacturing process of solar photovoltaic. However, pollution from solar energy is less in comparison to other sources of energy.
- Expensive to move
If you have plans to move from a particular location soonest, it is not advisable to install the solar energy yet. This is because it is quite expensive to move from one location to another. This is a disadvantage that should be noted. However, solar panels add value to homes, and in time the money invested in it will pay off.
The primary needs of man are food, shelter and clothe. Howbeit, these primary needs of ours are a connection with the need for a good electricity supply. You will agree with me that in this modern world it is almost impossible to meet these primary needs effectively without the use of a good power supply. Added to that is the fact that all old power supplies are based on unsustainable sources of energy like coal, gas and oil.
Subsequently, the advent of solar energy is a sure way to meeting our power supply needs and living a happier and healthier life. So when you think of an efficient power supply, think solar energy.
