The sun is a very valuable source to the world today. We use it for heat, plants use it to grow, and energy such as solar power. Solar power is the conversion of sunlight into electricity. Solar power is the next alternative to all other sources of energy out there. Fossil fuels such as oil and gas are non-renewable, which means they are limited.
Since the discovery of fire until late 19th century , human beings relied on renewable energy as an essential part of their life .The present world is moving quick towards improvement of human progress. Enterprises, manufacturing plants, control plants, different government foundations, logical establishments, private associations are experiencing childhood with the premise of accessible characteristic vitality sources. Be that as it may, these sources are restricted and costly. Fossil fuels are the fundamental sources that are being utilized to deliver vitality today. They are quick draining as well as polluting the earth, and influencing the financial soundness of numerous nations.
Creating and adapting new ways of utilizing renewable resources is becoming increasingly important. One of the most abundant sources of renewable energy comes from the sun in the form of solar radiation. The Pizza Box Solar Oven is just one example of how we can use the sun's energy as a clean source of power. Every step in creating the Solar Oven represents an important concept about how energy from the sun is harnessed. The Components of the Solar Oven Aluminum Foil: Reflects the light from the sun into the oven.
• Solar–thermal systems which solar collectors utilize. • Artificial photosynthesis which is being used for delivering carbohydrates or hydrogen via water splitting. • Passive solar technologies which are installed in buildings for improving solar lighting and heating. • Biomass
Simulation of Solar Photovoltaic System using MATLAB and XILINX A. Tirupathi Rao Assistant Professor, Dept. of EEE, G.M.R Institute of Technology Rajam, Andhra Pradesh, India firstname.lastname@example.org Abstract: Solar energy is the most abundant available source of energy in nature. This solar energy is a renewable energy source used for the production of electricity. With the present technologies improving day by day the solar energy will be getting more focused. In this paper the solar photovoltaic (PV) system is modeled and simulated.
Renewable energy is energy that is collected from renewable resources such as sunlight, water, wind, and geothermal heat. A common form of renewable energy is solar energy. Solar energy is radiant light and heat from the Sun that is harnessed by using technologies such as solar heating, photovoltaics, solar thermal energy, and more. The Sun releases pockets of energy called photons that travel from the Sun to the Earth in a matter of minutes. When photons hit a solar panel, they knock electrons lose from their atoms.
Technology history In 1839 a French physicist name Edmond Becquerel first observed photovoltaic effect, Becquerel was able to discover the creation of small voltage / electric current in certain materials upon exposure to light. In 1870, Heinrich Hertz studied photovoltaic effect on solid like selenium, after a while selenium cells were produced and were able to convert light to electricity with over 1% efficiency. Selenium was later adopted for use in the field of photography and incorporated in light measuring devices. Steps were taken in 1940s and early 1950s towards commercializing pv and the czochralski process was created for producing crystalline silicon which were highly pure. About 1954 at bell laboratories, scientist improved on the czochralski process and they developed the first crystalline silicon photocell with an efficiency of about
As far as a single solar panel can produce just limited amount of power, many installations contain several panels. This is known as a photovoltaic array. Advantages: solar energy is a resource that is not only sustainable but also indefinitely renewable. Solar panels also require little maintenance. After installation and optimization they are very reliable due to the fact that they actively create electricity in just a few millimeters and do not require any type of mechanical parts that can fail.
The heat is then used to boil water to drive a steam turbine that generates electricity in much the same way as coal and nuclear power plants, supplying electricity for thousands of people. Solar industry is helping to pave the way to a cleaner, more sustainable energy future. “Due to the country’s exposure to the equatorial sunshine, the OBG 2010 report cites solar energy as one of Brunei's most promising forms of alternative energies. Since ASEAN countries agreed to have 15 per cent of total installed power to come from renewable sources by 2015, it has become crucial for Brunei to boost the power it sources from renewable energy. “ as quoted from a local article in Brunei Times.
