Solar energy is the energy that we get from sun. Solar energy is most readily source of energy. It does not belong to anybody and hence it is free. It is the most important non-conventional source of energy because it is non-polluting and therefore helps in reducing greenhouse effect.
Solar energy is used since prehistoric times. In 1970s after the rise in oil prices, several countries began to formulate many research and development programs to use solar energy more efficiently.
The Earth receives a large amount of solar energy. Sun is a fusion reactor which has been burning over 4 billion years. In one minute, sun provides enough energy to meet world’s energy needs for one year. In fact, "The amount of solar radiation striking the earth over

In India, agencies like the Indian Renewable Energy Development Agency and the Ministry of Non-Conventional Energy Sources are making a programme to use solar energy in many households in the next few years. However, for this programme to be successful, the people’s initiative is very important.
India is the country with long days and plenty of sunshine like in Thar Desert. This zone, receives abundant solar energy and it is suitable for harnessing solar energy for a number of applications. Areas which receive similar intensity of solar radiation, solar energy could be easily harnessed in such areas. In India, Solar thermal energy is being used for heating water for both industrial and domestic purposes.
Solar power is just as practical in populated areas connected to the local electrical power grid as it is in remote areas. "An average home has more than enough roof area to produce enough solar electricity to supply all of its power needs. With an inverter, which converts direct current (DC) power from the solar cells to alternating current (AC), which is what most home appliances run on, a solar home can look and operate very much like a home that is connected to a power
Solar energy is energy taken from the light that reaches earth's surface from the sun. There are four different kinds of solar energy, which are active solar systems, passive solar systems, photovoltaic cells and concentrating power systems. An active solar systems is a system that captures solar energy by mechanical means. Common active solar systems are often in buildings or homes. Some examples are roof collectors and water heating. Low Intensity and high variability have limited the use of active solar energy in Canada. A pass...
When you stop to think about the earth we live on, you begin to realize how much of it we take for granted. The planet earth is teaming with millions of living organisms and countless mountain tops. This way of thinking could also lead you to ask the questions, “Where did our major source of energy come from?” To answer the questions, most living things depend on the sun as their ultimate energy source. Let me elaborate on that point more, what we have going on, on earth is more or less a system. A system is defined as a network of independent components and processes, with materials and energy flowing from one component of the system to another (McGraw-Hill, 2013). When describing how most living things on earth use the sun as their ultimate source of energy the following things are factored; Photosynthesis, herbivory, predation, and decomposition. Separate, it seems as though they have nothing to do with each other, but when you put them together it makes it clear how these factors are most living things sourc...
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
Everyone is looking for a better way to have power. Solar power has very dependable technology, with little to no maintenance. It can bring finical savings by making more power a home owner may need and you can resell back the power company. Lastly help the environment by having no waste so less pollution and takes up unused space by putting them on to the roofs of the houses. In the end Home owners should try looking pass the initial price of Solar panels and see that this is a great way to produce energy that does not produce any carbon foot print.
Our Sun continuously converts hydrogen into helium and with this process it provides the essentials for life processes. In doing this it controls “our climate, provides light, raises tides, and drives the food chain” (Schaefer 34). Our Sun also has influenced many beliefs now and in the past. History has documented Sun worshipping religions while many current societies use solar calendars (Schaefer 34).
In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on fossil fuels.
The prime advantage of this approach to harnessing solar energy is that the process is simplified by combining energy gathering and storage into a single step. This process is robust, stable and cheap. One limitation of this process is, while this is useful for heating applications, production of electricity would require another step using thermoelectric devices or producing steam to run a generator.
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.

... and monthly water filling. Solar energy is the cleanest and purest form of energy, allowing for cleaner air overall in our environment. There is great hope for a lot more solar panels to be installed worldwide. Solar is a viable alternative energy with solar panels becoming more affordable and more efficiently designed.
Solar collectors are special type of heat exchangers that transform solar radiation energy into thermal energy. The key component of all solar system is the solar collector. This is a device which absorbs the solar radiation from sun converts into heat and transfers this heat to a fluid ( air, water, oil ) passes through the collector. The solar energy collected is carried from the circulating fluid either directly to the hot water or to a thermal energy storage tank from which can be utilized for use at night or cloudy days.
In addition, Malaysia also focuses on solar energy because of the hot climate throughout the year, which makes it practical to use solar energy. Its location in the equatorial region is...
...t is readily available to us freely. The sunlight and heat will always be available to us because, it is a non-extinguishing resource and so, let us make use of it. With all these points made, there is no question that, solar energy is capable of becoming the world's future power supply.
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heats the panels, it produces electricity. Solar power produces energy during the day and can store energy for the night. Solar power does not pollute the environment. However, it has high maintenance cost, and it takes a lot of land space.
