How Does Solar Powered Electricity Work?

July 19th, 2010

The use of solar electricity is getting all the rage right now. What with booming solar powered products such as light fixtures and automobiles coming from every corner of the world, it’s only a question of when this method will overtake the world’s traditional ways.

So how does solar powered electricity work?

Before going to the nitty-gritty details of how solar power is created and used, here are a couple of terms that you need to be familiar with so that the discussion later on won’t be mind-bugging.

Solar is the term used for the energy acquired from the sun’s light that is utilized for household appliances, company equipments, etc. Photovoltaic cells or solar cells are found on solar panels, which are needed to acquire the rays of sunlight for the conversion of actual usable energy.

Now that you know two of the important terms about solar electricity, we now discuss how it is created.

Solar power is acquired through solar panels, which are placed on roof tops of buildings, houses and other structures. These solar panels have photovoltaic cells that allow for the conversion of the sun’s light to DC power. An inverter then transforms the DC power to AC power, which is what is needed for equipments and appliances to work. The AC power can also be stored as solar power can be generated all the time. This allows for fewer dues on your electrical bill and more cash on your pocket.

The strength of the production of solar power is also dependent on several factors. Because solar power is a cause of the sun’s light, heat is not a part of the equation. As long as the sun shines, even when there is snow, solar power can still be generated. The solar panels, as was discussed earlier, are important to be greatly exposed to the sun. The more exposed the solar panels are to the sun, the larger amount of solar electricity can be produced. External factors such as clouds and shadows affect how much solar power can be created. Again, exposure to the sun is very important for the production of this energy.

Solar powered electricity work hand-in-hand with solar powered devices. These devices require photovoltaic cells that are present in solar electricity. Devices like the solar car or solar powered light bulbs are just some of the examples invented to accommodate the energy humans can acquire from the sun.

Like any other resource given to us, solar power should only be used for the betterment of societal living and the environment’s stability. With so much environmental tragedies happening, solar power really sheds some light to the growing economic crises the world is facing. Solar power may be advisable for everyone’s usage, but not everybody is knowledgeable enough on this wonderful undertaking science has once again opened for us.

The use of solar electricity is easy but also requires financially investing for equipments such as solar panels. But in the long run, one will realize that this is only a small cost to a bigger reward.

Understanding Solar Power Generation

April 23rd, 2010

An increasing number of people are now considering the conversion of solar energy into usable power. Those of you who are not may benefit from understanding exactly how solar power generation works, how it is helpful both to us and the environment. Many people all throughout the world do not know a lot about it. Because of that, they do not realize its advantages either.

You may not know this, but solar power has a pretty enviable reputation. The sun has been a source of power for more than a thousand years. It is a renewable source of energy. That means that we will never run out of it. It has been around for millennia and it is not going to fail us any time soon. Given the fact that a fraction of solar radiation could power up the whole world, there is no way we could use it all.

Long ago – and still today – solar power was used as a heating device. Like say, that is still one of its primary uses. Installing windows and skylights into houses is one form of solar power – known as passive power. A lot of windows are centrally placed so that they face the south, and the house itself must be set up a certain way. Solar energy can also be converted into power through active solar power, which relies on various solar technologies. These usually have to be installed. These methods can make solar energy be used as a heating and cooling source, in addition to providing power. Naturally any form of solar power also provides its own alternate light source, straight from the sun in the sky.

Solar panels are a popular technology associated with active solar power. You have problem seen them – on house roofs, in backyards, et cetera. They have been around since the nineteen seventies. They were known as solar collectors at that time. As the name suggests, they collected solar radiation, then later converted it into power. They were placed roof tops and able to work appliances.

Solar panels are the next phase of collectors, you could say. You can have them installed in a variety of places. Some of them can even be placed within your house. A popular method is to let the panels power the house during the day, while at night the power is run on batteries. These batteries get their juice from the heat stored in the panels.

Solar power generation can also be applied to water systems. That is right, there are solar powered hot water systems. Sometimes people choose to place the water tank outside, sort of like a cistern. The sun keeps the water hot. Other times, using active solar power, people choose to have water tubes running alongside their solar panels. The water gets heated as it runs along the tubes.

Solar cells can be used on laptops, cell phones, and other such devices. The solar cells, too, juice up the batteries within those items. The use of an inverter converts them to AC power.

Using solar power can save you money as you help save the environment. Neither the sun nor its radiation rays cost a penny. The only fees you will have to pay will involve installation and maintenance, and they do not go on forever. Besides, the sun renews itself. When you do not have to worry about running low on a power source, the cost is significantly lower.

All You Want To Know About Solar Panels

February 10th, 2010

No one has a doubt that our planet is facing all round environmental degradation due to human intervention. However, there is a growing realization now that all this needs to be stopped and reversed. Hence, there are ways to find out about the eco-friendly, green, sustainable, alternative and renewable energies and technologies, which can contribute to make things better. There is a strong belief that the technological innovation and intervention in renewable sources of energy like sun, wind, ocean thermal gradient, tides, etc. can help us out in this situation. Out of these, the solar energy is, perhaps, the most important.

The utilization of the solar energy is currently being done by two technologies:

a) the photo-voltaic technology, and

b) the solar thermal technology.

The photovoltaic (PV) technology is used to make solar panels and it involves the conversion of solar rays into electricity which, in turn, is used for running a variety of electrical appliances. The thermal technology, however, directly converts the solar rays into power as in solar cookers.

PV solar panels come in three types of thin film varieties: mono- crystalline, multi-crystalline, and amorphous. A PV cell is made up of one or more layers of semi-conducting material, which is more often silicon, an expensive but indispensable proposition. On reception of sunlight, an electric field develops across the silicon chip layers resulting in a flow of electricity. Normally, two designs of panels are available, flat-plate and concentrator. The PV Solar panel can produce some electricity even under cloudy conditions. The intensity or strength of PV cells is measured in terms of kilowatt peak (KWP). Thin films cost less to produce than silicon cells as they are made up of wafer thin layers of photosensitive material, and the manufacturing process consumes less energy. Thin films can be embedded in roof shingles, windows, and sidings.

The solar panels can be installed on the roof tops of the buildings that do not come under the shadow of any other building or something else. They should preferably be south facing. The panels are mounted on poles or platforms and cover considerable area.

Before opting for this type of technology, a reasonable assessment of the power requirement shall be made. The cost-benefit analysis shall be done duly considering expenses like the initial capital outlay, installation, and regular maintenance cost of the solar panels, the benefits like the tax credits and subsidies from the government, savings from the monthly electricity charges, etc. Social and environmental factors like reduction in pollution, reduction in global warming, dependence on fossil fuels, etc. shall also be considered. The benefits far outweigh the costs in the long run.

These panels can be used to run a variety of appliances at home and at commercial establishments like the bulbs/CFLs, solar geysers, solar cookers, water pumps, fans, traffic signals, heating and cooling systems of the building, etc. However, it shall be noted that the panels function best when these are utilized optimally, which means that these are not used to run high-wattage appliances if the installed capacity is less.

To top it all, the electricity generated by the alternative renewable sources of energy including the solar panels can be sold to the power company and this means generation of regular income for the individual. So, these have earning potential as well.
