The exponential rise in the use of technology on a global scale is making way for numerous innovations. These innovations are going to change the way we do things and perceive things. Also, they have the potential to bring about many useful changes. One such technology is the use of solar panels to make electricity. Solar panels are getting popular all across the globe. It is because they are highly sustainable in operations and produce electricity enough to power big projects. The good news is that you can make your solar panels to create heat and save costs while benefiting the environment as well. If this sounds like something you are interested in, you are in the right place. We will tell you all about how you can make your solar panels easily.
Sun is the most significant source of energy in the world from the dawn of time. The heat and light received from the sun consist of electromagnetic radiations, including heat light and radio waves. All forms of energy (except Nuclear) ultimately comes from the sun. It has been an integral part of our Eco-system, from helping plants in making their food to melting glaciers and fulfilling other nature’s requirements. With time man has found different ways to use this abundant source of power to fulfill its own needs. In ancient times people use magnifying glasses to create a beam that could make the wood catch fire. Still, with the passage of time and innovation in technology, the man produced machines that could convert this power of sunlight into other forms of energy.
Solar energy means the energy received directly or indirectly from the sun. The process of converting sunlight into useable energy like electricity is called the solar energy process. With the invention of the solar cell, which converts direct sunlight into electricity, solar energy finds a way into our daily life. These cells are consist of p-type silicon crystal and n-type ( semiconductor). These solar cells are used to power electronic devices such as pocket calculators. Solar energy has a vast scope; it is not only used for making electricity also for heating water, making buildings withstand the heat of sunlight. It has enormous potential because the majority of our population lives in those areas sunlight the majority of their time.
The solar energy process
To further understand the solar energy process, here is some basic example light radiation causes electrons to be released and creates a potential difference so current can flow between electrodes connected to the two crystals. All wavelengths are shorter than one micrometer can produce electrical energy. Cells convert c.10% sunlight into electrical energy. Another process of solar energy starts when a collector in the solar panel collects solar energy from the sun stores it into its backup after that a chemical reaction in the machine attached with the backup converts this stored power into electricity. In another case, the heat from the sunlight heats the pipes installed on the rooftop. After that water crosses from those pipes, the heat of the pipes changes the temperature of the water, making it hotter.
In a broader perspective, solar energy covers all aspects of using sunlight in different forms of applications using photovoltaic(PV) cells, solar heating, solar thermal energy, and artificial photosynthesize.
In other words, Solar energy includes all the methods from which man can harness the power of sunlight. The technology is contently evolving, not only increasing our energy needs but also introducing new ways to use solar energy. In the present time, techniques using solar energy are becoming an essential part of catering to our energy needs; many countries, both developed or underdeveloped, are shifting towards solar energy. The latest setups of solar energy power generation can provide electricity to a small city.
It is no secret that human activities are leading to various issues for the environment as a whole. These activities are resulting in issues like climate change. It is a responsibility for all of us to play our part in making a change to shift towards more sustainable practices. But, what if you could save money by making a lasting change? We are talking about using wind turbines to produce electricity. You can easily create a wind turbine that will be enough to fulfill your domestic electricity needs. However, if you do not know the first thing about making wind turbines, do not panic. In this article, we will tell you how you can make a wind turbine to create free electricity in a highly sustainable fashion.
What is a wind turbine?
A wind turbine uses the energy in the wind to make electricity. The different blades of the fan turn to rotate a turbine. The blades are connected directly to a rotor. The rotor is then connected to a shaft. By operating on this simple mechanism, wind turbines create electricity.
Why a wind turbine?
There are scads of reasons why using wind turbines for creating electricity is a good option. The most impactful goal here is the high level of sustainability that is a part of the process. Also, you can significantly cut down the cost of the expenses by using wind turbines.
What is the minimum speed needed?
About 2% of the total resource of solar energy reaching the surface of the earth is converted into kinetic energy, which the wind holds. The function of wind turbines is that they use up the kinetic energy of the wind and change this into electricity without any harmful emissions to the environment. The division of wind throughout certain areas is quite mixed and uneven. Therefore, class 3 winds are the standard requirement for the wind turbine to produce energy. A class 3 wind has a speed of 14.3mph or 50m.
As it is evident from the facts above, high wind speeds can be beneficial in generating more electricity because the more the turbine rotates, the more energy it produces. Since wind turbines are easier to install and they also do not have any harmful emissions to the environment, governments are promoting their use so that electricity can be created through cleaner means. Farmers are also moving towards the trend of using wind turbines as an alternative to mechanical turbines because wind turbines can pump double the water with the same initial investment. A research study further says that about 20% of the electricity in the future will be generated through wind turbines.
Now that you are aware of how wind turbines can help generate electricity and what minimum wind speed they require to generate electricity, you can easily make an informed decision. You can also save significant levels of costs that you incurred previously due to the consumption of electricity.
