The sun is a great source of energy. It would be great to use solar energy in your homes especially nowadays when the prices of oil and gas continue to increase. Because of the high fuel and gas prices, more and more people are experimenting on the use of solar energy in their households in their attempts to minimize the costs of basic utilities.

The sun’s energy can be harnessed in different ways depending on how you would utilize the end product. There are so called solar collectors which are placed on the roof tops or used in buildings. The main purpose of these solar collectors is to provide heating and even ventilation for the houses and buildings. These collectors harness the sun’s energy by magnifying the sunlight several times and transferring that heat to air or water. That heated air or water is stored and will provide the building or home heating and hot water whenever needed.

The only problem here is that not all places have equal amounts of sunlight. As you go farther from the equator, the strength of the sun is reduced. But still, this is a much better solution than relying on electric grids which do not reach remote areas. It is just a mater of storing the heat generated from the solar collector properly. For example, some buildings in Sweden utilized an underground storage facility where solar energy is stored resulting to savings from heating the building and their water.

In areas where gas and fuel are out of reach of the pockets of poor communities, residents have to rely on solar cooking for their meals. They use this bowl shaped discs equipped with mirrors or reflectors which directs all the sunlight on the middle where a pot is placed. The same technology is being used in India, Sri Lanka, and Nepal. This serves are a good alternative from conventional fuels like coal, firewood, and gas. They can use these solar stoves during a sunny day and use traditional fuels when the weather is not that good.

The information about Solar Energy presented here will do one of two things: either it will reinforce what you know about Solar Energy or it will teach you something new. Both are good outcomes.

This reliance by communities on solar cooking should encourage more studies on how to make photovoltaic cells cheaper for an ordinary household. At this time, the use of solar cells is not economically friendly for a single household. However, the approach here is to install a series of solar panels which would be shared by the whole community. This could be a good idea depending on your usage, but for basic lighting purposes these could work in small poor communities.

In some areas, community cooperatives have found ways to bring electricity to households out of reach of power grids. In the Philippines for example, a local cooperative provided households loans to enable them to install a basic solar power module which can produce enough electricity for three light bulbs. This ay be laughable in our standards but to these people who have been living all their lives with the flickering light of the candles, three electric light bulbs make a great deal of a difference.

The story is the same in other countries. In Israel, the high costs of photovoltaic cells have clamped down the growth of solar energy in the country. It if fortunate, therefore, that the Israeli government is now providing incentives for households that would use solar energy.

However, according to industry analysts, the costs of solar cells production will go down as the demand increase. Also, most are hopeful that recent discoveries and advancement in technologies will find a way to bring down costs of using solar energy.

Ordinary households using solar energy is an ideal scenario that we should all strive to achieve.

The only way to keep up with the latest about Solar Energy is to constantly stay on the lookout for new information. If you read everything you find about Solar Energy, it won’t take long for you to become an influential authority.

Today in center stage is a battle for the ages. On the right corner, packing a hurricane punch yet is known to move softly as a breeze is wind power. On the left corner, with a scorching hot aura, moves in a speed of light, is solar energy. Wind power versus solar energy, which one is going to be declared the champion of the alternative energy movement?! Let’s get ready to rumble!

Or something like that. I apologize for that intro but I just can’t help. I figured that if I was going to match one alternative energy resource against the other, then I’ll make some extravagant introduction. Just imagine the drum rolls.

Actually, there is an existing debate among environmentalists and even scientists on which energy resource should be developed first given their advantages and drawbacks. Staying away from the personal biases, numerous studies have shown that overall, wind power is more cost effective than harnessing the sun’s energy. Let’s see the reasons behind that conclusion.

Harnessing the sun’s energy can be done by a number of ways. But probably the simplest way which can be applied in a small home is by using photovoltaic cells or PV or solar cells. What happens is that sunlight hit the surface of a photovoltaic (PV) panel which responds by creating free electrons which is channeled to generate an electric current.

Wind power on the other hand utilizes a propeller and a shaft system which has a magnet wrapped by a coil of wire inside. As the wind turns the propeller and the magnet inside, the electrons in the wire are forced to move along the wire producing an electrical current.

Think about what you’ve read so far. Does it reinforce what you already know about Solar Energy? Or was there something completely new? What about the remaining paragraphs?

Both ways are quite simple but the complexities now lies on the costs of producing the necessary equipment especially the mechanisms that will maximize the power output. When costs of production of photovoltaic cells and wind turbine are compared, the latter is much cheaper to produce. Although, manufacturers of photovoltaic cells stress that as the demand on PV cells increase, the costs of production decreases. So its just a matter of time before PV cells become price competitive.

Other problems include the logistics of placing the equipment. A solar panel requires quite a large space plus, your location on the globe will affect the amount of sunlight you receive and consequently the amount of power you produce. The further away from the equator you are, the less amount of sunlight you can harness. Also, on the average, the PV cells have a 15-20% efficiency rate.

The problem with wind power on the other hand is that not all areas will have winds favorable for a turbine. And if you do locate a place where winds are strong and the turbine can be maximized, you’ll find that the area (more often than not) is inhabited by various species of birds. You don’t want to kill birds with your turbine, do you?

Now going back to our wind power vs. solar energy match-up, indeed we do have to agree that wind power is more cost efficient. However, both alternative energy resource will play a big role in our future.

It is, therefore, in my humble opinion that we both develop the two technologies simultaneously for each one has their advantages and disadvantages and each one can be properly utilized for specific areas.

Are you familiar with the World Solar Challenge? It is a race specifically for solar cars. Solar cars basically have arrays of photovoltaic cells which converts the sun’s rays into usable electrical energy. The purpose of the race is to raise awareness on the use of the sun’s energy on transportation and the development of other alternative forms of energy particularly the solar cells.

The future of using solar energy on transportation services may still be a little hazy given the practical difficulties involve in converting ordinary cars into solar cars but the idea is here to stay and hopefully develops into something promising and useful.

At this point, solar cars have been built to join solar car races. Very few have been constructed for practical and commercial purposes. There are several reasons why the solar car remains on the background.

The design of a solar car relies on the electrical system of the vehicle. The system controls the electricity the flows from the photovoltaic cells to the batteries, to the wheels, and to the controls. The electric motor that moves the vehicle is powered purely by the electricity produced by the solar cells. The solar cells, depending on the number installed on the vehicle, can produce more or less 1000 watts of power from the sun’s rays. To give you an idea, 1000 watts is just enough electricity to power an electric iron or even a toaster.

How can you put a limit on learning more? The next section may contain that one little bit of wisdom that changes everything.

And since the sun will most likely be covered by clouds at one time or the other, or the car goes through a tunnel or something, solar cars are equipped with batteries to serve as backup power supply for the motor. The battery packs are charged by the solar cells. However, the batteries are not charge while driving the solar car unless you intend to go very slow.

Just like a gas pedal in conventional motors, a motor controller regulates the amount of electricity that enters the motor to speed up or slow down the vehicle whenever needed. Solar cars are not that slow as perceived by almost everyone. These cars can go to as fast as 80-85 mph.

With this, you can see why solar cars are not yet into commercial production. Nowadays, solar cells can harness more than 21% of the sun’s energy that hit the surface. If the time comes that the cells can actually get more energy from the sun then maybe we can see solar cars on the streets. But at this time, it is quite difficult to make a commercial production model of a solar car.

Nevertheless, there are companies who have already created some concept solar cars and are testing how road worthy they are. There’s even a scooter that is street legal and runs from batteries charged from photovoltaic cells. Other possible application of solar car technologies is on golf carts which runs pretty slow in the first place and can be appreciated by golfers as well.

The future of solar energy on transportation is still not that clear. The application of solar energy on homes and buildings has been moving forward in recent years so hopefully we can find new ways of converting the sun’s energy into usable electricity. And this time something that can be economically and efficiently installed in conventional cars.

Of course, it’s impossible to put everything about Solar Energy into just one article. But you can’t deny that you’ve just added to your understanding about Solar Energy, and that’s time well spent.
