In our society, almost everything powered is because of electricity. Electricity has been the main source of energy since the 1800’s. As more and more people are realizing the substantial, irreversible damage of fossil fuels, and that the cost of electricity is rising, they are seeking alternatives. Eventually, fossil fuels will run out. As opposed to fossil fuels that are un-renewable, you cannot run out of solar power. According to NASA, we have the sun for another 6.5 billion years! Our sun, the center of our universe is roughly 27 million degrees. Although only a little bit of those rays reach us, it is still enough to power the whole world. There are 3 types of solar panels: Monocrystalline, the most efficient and most expensive, Polycrystalline, the most common, a little less efficient, and a lot less expensive, and Amorphous Silicon or “Thin Film”, the cheapest, not effected by shading, but their efficiency is lowest. On your average day, the sun shines about 1,000 watts of energy per square meter, and that is more than enough energy to power our electricity needs. There are lots of pros and cons facing this controversial subject. Fossil fuels are easy, and standard, where as no one really knows anything about solar energy just yet. Fossil fuels will run out eventually, it’s time to learn. Solar energy is renewable, and abundant. “The surface of the earth receives 120,000 terawatts of solar radiation – 20,000 times more power then what is needed to supply the entire world.” As well as being renewable, and abundant, it is sustainable. There will be no way to over consume solar energy because sustainable energy sources only meet the needs of the present. The next is clear, environmental friendliness. Although with manufacturing, transporting, and installing come emissions, the damage is minuscule compared to the damage that non-renewable energy sources have on our earth. “It is clear that solar energy reduces our dependence on non-renewable energy sources. That is an important step in fighting the climate crisis.” xpensive, and Amorphous Silicon or “Thin Film”, the cheapest, not effected by

CHAPTER 3: SOLAR PHOTOVOLTAIC ENERGY CONVERSION
3.1 Introduction to Solar Energy
Solar energy is gets by the radiation of the sun. Solar energy is available on the earth continuously and in abundant manner. Solar energy is freely available in the nature. It doesn’t produce any gases and it is pollution free. It is free of cost and has low maintenance cost. Only problem with solar panel, it cannot produce energy in bad weather and climate condition. But it has greater efficiency than other energy…
In today’s society, energy is needed in order to provide for a modern way of living. Most people need it for cooking, transportation, and even communication. As energy is becoming more and more necessary, many people are starting to turn toward a cleaner power solution, like solar energy. Solar energy is a very effective solution to obtain energy because it is great for the environment and is becoming widely available.
Every day the sun is shining and giving the Earth warmth…
out many ways to use all kinds of energy to power our everyday products. Today there are many discoveries of different energy sources that have helped us greatly. We have now started to use alternative energies to help with the depleting resources. One of these energies is solar energy. Even though this alternative has helped with the conservation of resources, this has become a huge cost and toll on the economy that has affected it greatly. Solar power using solar panels has become a bigger cost than…

PROJECT RELEVANCE AND NEED
The sun has been producing energy for many millions of years. It is estimated that there is enough hydrogen still in the sun's core to last another 4.5 billion years. Solar energy as we refer to it is the solar radiation in the form of light and heat that reaches the earth. Every day the sun radiates enormous amounts of heat and light energy. The planet and the atmosphere absorb some of this energy with the remainder being reflected back…

Sun, wind currents, and plant-life of many varieties are the most important energy choices for our new planet. The sun is important because we can use solar energy to power most of our needs instead of using electricity that uses terrible fossil fuels. As stated by the power point in our class, “Passive solar heating uses solar energy to heat buildings without the use of equipment. Savings can be as much as 50% of heating costs.” Not only will we be saving our environment from the bad fossil fuels…
an alternative energy source that could be used as a primary form of power supplying, especially in a country like Saudi Arabia, where the sun is out for most of the year. Solar power is an alternative form of energy that is being adopted around the world. Solar panels refer to a panel designed by using photovoltaic cells to absorb the sun’s rays as a source of energy for producing electricity or heating. Photovoltaic cells or solar cell are the electric device that covers the energy of light directly…
What is Solar Energy
The sun has produced energy for as long as the earth has been around.
Solar energy is the sun’s rays, (solar radiation) that reaches the Earth. It is
the radiant light and heat from the sun that has been harnessed since ancient
times. It is also one of the of the many renewable energy sources available
to man, but for now cannot replace fossil fuels 100%.
Solar energy can be converted to electricity. This is done in two ways.
One, by using Photovoltaic…
B) Only 60% of gas produced energy of electricity which was sent to the power grid and the remaining energy was lost in the form of heat due to the blades having to overcome air resistance and also the friction of the turbines.
C) Wind energy is less efficient (even when running at their optimum wind speed) because There's friction between all the moving parts, the generator or alternator aren't 100% efficient, and the energy is lost at the rotor blade friction and drag, gearbox losses, generator…
