Solar Energy in aircrafts?

The truth is, planes may never be able to carry passengers if they are run solely off of solar energy. Planes take enormous amounts of energy to fly, and solar power may not be enough. As of now, most solar-run aircrafts are used for surveilling only (Nasr, para. 4).

If you thought that having a solar powered car was cool, then you will love the idea of a solar powered plane! The plane, much like the car, is more of a concept with no real big production- the reasons being is that you can't really put a lot of people on these planes. It may not look like it, but the plane showed above is very thin. This being the case, it cannot have too much weight to carry. The wings are covered all across with solar panels to power the motors. Another major flaw of solar powered planes is cost, which can be in the millions.
Below I have a link to a video of the plane in the picture above making its journey across the United States!

Solar Energy in cars?

Cars are using solar energy to make them run. There are so many advantages to solar powered cars, such as ninety percent of the energy produced going straight to the car, versus fifteen percent from fossil fueled energy (Solar Energy Cars, para. 11).

Solar powered cars are a new and upcoming idea in the solar energy world. They are a good idea as they will cut down on the amount of carbon dioxide emitted into the air. Being a new idea, and the fact that not many solar powered cars are actually produced, it is more so a concept than a reality. The price of producing a car like this would be very expensive. The car would have to be covered in solar cells which are expensive to make. Another problem is that even though the car is covered in solar cells, it still may not be enough to power the car to the standards of a normal car taking into account highways, road conditions, inclement weather, etc. Solar powered cars are the future of automobiles- there has already been progress made in electric cars. People need to make the small steps toward completely solar-run automobiles.
                                                 

How is Solar Energy incorporated into homes?

Solar energy in homes is the most popular among all of the many uses in solar technology, due to the many advantages of it. From 2000 to 2013, solar panel capacity increased to supply power to just about two million homes (Rogers, 2015, para.5)

Solar energy can be used to power homes all over the planet. It could be quite beneficial to rural parts of the world where people need electricity and power to help sustain human life. The basics of solar energy incorporated into homes is pretty obvious; there are solar panels put on a roof of a house and those panels collect sunlight. Truth is, there is more to it than that. The solar panels on the roof have cells that collect the sunlight, and turn the sunlight into direct current electricity. The electricity then gets sent to an inverter in the home, that turns the electricity into an alternating current. This is what the outlets and appliances in homes use. Most of the time batteries are attached to the inverter to store any unused or excess electricity. The great thing about having solar panels for your home, is that you can sell any stored electricity back to the grid. This is how the solar panels pay themselves off in the long run.
Below I have a brief video that gives a basic on how solar panels work.
