Solar Energy
by Sydney Rice, Abby Watson, and Haneen Musa
How efficient are solar panels?
Most solar panels on people's houses are fairly inefficient. Less than 14% of the energy that reaches them will be converted into electricity.
Renewable
How is the Sun used to generate energy?
Nuclear fusion converts hydrogen atoms into helium. The by-product of nuclear fusion in the sun's core is a massive volume of energy that gets released and radiates outward toward the surface of the sun and solar system beyond it. The sun radiates/emits energy towards the Earth and then we collect the sun's energy and transfer the rays into electricity which can be a renewable energy.
Where is solar energy used now?

Ranking Country Installed PV [MW]
1 Germany 32,411
2 Italy 16,361
3 China 8,300
4 USA 7,777
5 Japan 6,914
6 Spain 5,166
7 France 4,003
8 Belgium 2,650
9 Australia 2,650
10 Czech Republic 2,072
Abundant
Maintenance
The majority of today's solar power systems do not require a lot of maintenance. Residential solar panels usually only require cleaning a couple of times a year. Technological advancements are constantly being made in the solar power industry. Innovation in nanotechnology and quantum physics has the potential to triple the electrical output of solar panels. Solar panels will keep being remodeled and revised to be better for people and our world

Fun Facts about Solar
Energy !!
Solar energy is renewable. This means that we will never run out of solar energy. We will have access to solar energy for as long as the sun is alive which is estimated to be billions of years from now. Solar energy is available all over the world.
The potential of solar energy is beyond imagination. The surface of the earth receives 120,000 terawatts of solar radiation (sunlight) – 20,000 times more power than what is needed to supply the entire world.


Solar panels give off no pollution. Once they’re actually installed on your home, they are doing absolutely nothing negative to the atmosphere; this is a huge difference than what you see from other forms of standard energy.
Pollution
A disadvantage of solar power is that it cannot be created during the night. The power generated is also reduced during times of cloud cover (although energy is still produced on a cloudy day).
Production Times
A big con of solar energy is how much it costs to install the solar panels on your home. The costs of the best quality solar panels will be above $1000, and many families will require more than one solar panel. This makes the starting cost of solar panels very expensive. It will take up to 10 years to 15 years before you can break even with your initial investment
Costs of solar panels
Pollution
However solar panels do not release pollution, a lot of pollution is caused to build the solar panels. Solar panels are made up of silicon and other toxic metals like mercury, lead and cadmium which cause a lot of pollution.
The country who uses the highest amount of energy from solar panels is Germany
Summer is obviously a better time to collect solar energy. In the U.S the best states to use solar energy tend to be the states closest to the equator where the sun's rays are much stronger.
The price of residential solar power. On average the total cost of solar installation can be between $15,000 to $29,000 for average sized systems sized between 4kw and 8kw. Sun run solar lets you get started as little as $0 down and helps you lower your electric bill.
Yes solar energy is being collected here in Washington State. There are currently more than 135 solar companies at work throughout the value chain in Washington, employing about 2,262 people.
No air or water pollution is given off when solar panels are used for energy production. It does not require transport of fuels or disposal of waste products. Solar energy produces electricity and causes very little sound, so there also no sound pollution caused from solar energy
The world’s first solar-powered bus was introduced in 2013, in Adelaide, Australia. Adelaide’s city council was keen on reducing the city’s carbon emissions as more than 30% of it came from transportation, both public and private. So, hopefully in the future more solar powered vehicles will be invented across the world. They would reduce a lot of pollution emitted.
~ Solar energy produces no pollution, has no environmental effects and is ecologically acceptable.
~ Space missions by various countries use solar energy to power their spaceships.
~ Solar energy is very reliable source of energy.
~ Solar energy can also be used to power calculators.
~ Solar energy has been used for over 2700 years.
~ Clouds and pollution prevent the sun’s rays from reaching the earth.
~ Solar energy is the most abundant energy resource on earth
~ the Sun was born about 4.57 billion years ago and has another 6-7 billion years before it becomes a white dwarf
~ many spacecrafts rely on solar energy
The history of solar energy is as old as human kind. In the last two centuries, we started using the sun's energy directly to make electricity. In 1839, Alexander Eamona Beguerel discovered that certain materials produced small amounts of electric currents when exposed to light.
Solar energy can be provided through solar panels. Solar panels absorb the sun's rays to power everything.
