Solar Power

Since the U. S. is at war in the Middle East to protect its foreign oil interests, we have seen a rapid fluctuation in oil prices, first 35$, and 70$, and in recent days 115$` (Matthew Knight, CNN). As China, India and other nations rapidly increase their demand for fossil fuels; future fighting over energy […]

Solar cell experiment

Solar Cells are used to convert available light into electrical energy. They do this without the use of chemical reactions. This conversion process is based on the work done by a French physicist named Alexander Becquerel in 1839. He discovered the photoelectric effect which describes the release of positive and negative charge carriers in a […]

Solar cells

This case study involves researching about solar cells and study the effect internal resistance has on its efficiency. This ties up with our practical investigation where we investigate the internal resistance of a power supply.Sunlight can be converted into electrical energy using photovoltaic cells also known as solar cells. Photovoltaic (PV) cells are made of […]

Solar Panels

Solar Panels, also known as Solar Cells, convert solar energy into electrical energy. When sunlight hits the solar panel It knocks electrons loose from their atoms and then they move through the built in circuit, thus creating a current of energy. This energy can be stored In batteries for later use or It can be […]

Solar Power and its environmental benefits

Solar energy is given off by the sun. It consists of light, heat and other forms of electromagnetic radiation (Pater 189). Solar energy is produced by nuclear reactions that take place inside the sun (Pater 189). Every 40 minutes, the sun delivers as much energy to the earth’s surface as all the people on the […]

A Research Paper On Photovoltaic-Based Solar Energy

With pollution reaching alarming rates in present day and looking to be increasing year in and out, it seems wise for us to find means to cut down on activities that may worsen the situation. In different parts of the world, numerous research institutions and departments at universities are nowadays devoting more and more time […]

Solar energy

Solar energy powered air conditioners have shown a great potential, for the reason that the high demands of air cooling have coincided with the huge amount of sunlight that is available in plenty. Since solar energy is available in plenty and this is the main resource for a solar powered air conditioner, therefore, Solar Air […]

Solar Panel

Solar panels are an eco-friendly electric generator. Solar panels generate electrical power from the sun by converting sunlight to electricity with no moving parts, zero emissions, and no maintenance. The solar panel, the first component of a electric solar energy system, is a collection of individual silicon cells that generate electricity from sunlight. The basic […]

Photovoltaic Cell

The name photovoltaic covers a set of technologies that convert sunlight into electricity using an electronic device known as a solar cell. While the photovoltaic effect was first observed in the 19th century, the first practical solar cell was constructed only in 1954. Since 1958, photovoltaic devices have been used to provide electric power to […]

Solar Power Electricity Generation in Nepal

Nepal is often jostled up amongst the facts and myths when it comes to hydro- electric power generation. There are facts that relate it to one of the richest countries in the world when it comes to resources. Then there is a myth, for a nation with such bountiful resources would have never been deprived […]

The Benefits of Solar Energy

Solar energy represents the future of a clean earth in days to come; it also represents the clean air that our children and their children will breathe. We constantly have to worry about pollutants in our air from all of the many harmful chemicals being thrown into the air by fossil fuels; we never stop […]

Hydro electric in malaysia

Introduction Large or small hydropower, still far the most important of the renewable energy for electrical power production worldwide, providing 19% of planet’s electricity. However, hydropower on a small scale remains the most effective energy technologies to be considered for rural electrification in less develops country. The advantages of small hydro technology are the system […]
