Solar Energy And Solar Panels

With current energy resources becoming scarcer to produce, countries around the world have been developing alternative ways for people to utilize energy. Presently, solar energy is the leading choice in those development processes.

Solar energy utilizes the power radiating from the sun. Dating as far back as ancient times, the use of solar power has accompanied human civilization in many different ways, adapting to the technological advances made from century to century. However, because of the mass boom in technological advancement, other more manageable energy sources like coal, oil and natural gas became the dominate source for powering technology. Unfortunately, because the amount of power needed to keep current technology, running many of these natural resources are running out, thus causing mass panic and scientist trying to harness other forms of energy.

Solar energy seemed like the most promising for the reason that human beings have such a rich history utilizing it in the past and the fact that it is a constant renewing resource. Nevertheless, trying to adapt that power for modern technology has taken decades to even make the little breakthroughs available today.

One of the breakthroughs being implemented into everyday life comes in the form of solar cell panels. Presently, solar panels are used to offer electrical power for both private and commercial consumers. The rays of heat driven down to earth by the sun filter through the solar cell causing an electrical current to form. The current then flows through the wiring in both residential homes or commercial business establishments, giving power to all electrical appliances within such as computers, televisions, stoves, microwaves, etc.

Alas, because the amount of energy needed to power even a single home cannot be produced from the small amount of energy that forms from a single cell, multiple panels are required in order to fully do any good. A typical installation includes a great amount of solar panels, batteries and an interconnection wiring.

Adapting the process for current technological and economical needs, developers have implemented the thin film modules sources that convert the solar energy. These third generation solar cells are indeed advanced thin film cells and when used on current panels provides high quality and efficient conversion at an extremely affordable cost. Those who recently have chosen to work with panel energy most likely have used the third generation solar cell technology.

Module panels are generally tested under a set of rules called Standard Test Conditions. Solar panels are expected to withstand weather elements such as rain, cold, head and hail for a long time. Some companies offer their loyal customers specific warranties that guarantee production for no less than ten years at 90 percent power and 25 years at 80 percent power.

Pricing on solar panels tends to vary depending on the amount of power and space needed. The three price ranges include small quantities, mid-range buyers, and large quantity buyers which has low cost deals. Although somewhat expensive to start, solar panels over time save the user money and help contribute to an alternative energy source.

How Solar Cells Can Save You Money or Electricity:

Everyone would agree that saving as much money on monthly power bills is a big plus for the budgets of most families. You can easily draw from the suns energy to power your whole home using solar cells. Some companies will even provide you with a kit to make your own cells to save even more money.

There are different kinds of cells that run on solar energy. You might choose to use the multi-crystalline cells as well. These are actually some of the most popular ones of all. Many students use these to make their own experimental solar cells. If they can do it in their experiment, you can do it to power your whole house easily and save a lot on your electrical bills.

Poly crystalline cells are efficient as well as being powerful in drawing off the energy of the sun. You can get these kind in a solar set as well. This set will allow you to be able to build your own system. This is a great way to learn the intricate tricks of how solar power really works.

Cells that are for converting solar energy into power happen when photons are turned into electrons. This can occur when the environment is right. The cells are made of material that is semi-conductive in nature. This is a must for the electricity to evolve from sunlight.

Electrons that are set free through a light source must have an electric field to be able to go in a certain direction. The conductive material used in cells is what sets this directional pathway for the free electrons. A current is what that stream of electrons is called. When metal surface are put over and under a cell, the current can be drawn on.

While this all may seem a little confusing, it really becomes quite simple when you hold an actual cell in your hand. Through building solar cell kits, you may learn even more about how the suns energy can do more than just help you to get a tan.

Solar panel review provides an understanding of factors involved in investing in solar and renewable energy systems. With major players entering into the solar manufacturing, one wonders how to make an educated decision. Actually it is easy to find out which path to go. The secret is in knowing various pieces of information and how they relate to your situation.

To have a systematic approach, I define the decision making procedure into 3 areas:

1- Economics of the system.

2- Efficiency of the solar panel and supporting accessories.

3- Technical knowledge and skills.

Solar panel review should cover these areas to help you in your project. Economics of the system discusses the cost, geographical location, warranties, etc. The efficiency of the solar panel gives you the return on investment figure. The last and the most important issue is how knowledgeable you are in terms of the technology of the solar panels. In solar panel review I will try to get into more details of the technology driving this sector.

Solar panels are made of silicone materials. It is almost the same material used in semiconductor components. Examples of semiconductor components are transistors and Integrated Components widely used in computers, audio systems, TVs, and of course the cell phones.

To get a better understanding in solar panel review, I like to use an analogy to batteries. Let’s consider a portable CD player. It can be powered with several batteries. Using several batteries allow achieving higher voltage values by connecting them in series. If you connect six C Cell batteries, you get 9 volts (six times 1.5 volt for each battery). One might ask why not use a single 9 volt batteries instead. It would be much more convenient and the equipment can be made smaller. The answer relies in the fact that more individual batteries provide more power than a single 9 volts battery. (It should also be mentioned that if you open a 9 volt battery, you would find inside several small batteries). However if someone could hypothetically make a single 9 volt battery, it would be able to supply more power than individual batteries connected together.

The solar panels are made in two types; one of them is called monocrystalline. It is made up of one silicon crystal. Its physical characteristic is distinguished by a color resembling semi-transparent layers which look like different colors mixed with black color (Similar to color of gasoline poured onto the asphalt). They are more money than the next type. They are meant for higher temperature climates.

The other type is Polycrystalline solar panels which are made up of smaller individual cells which look like a tiled surface. They are less expensive, because it is easier to manufacture smaller cells and connect them together. They are meant for cooler temperature environments.

When reviewing solar panels, one has to also consider the accessories that go with it. For example, I can mention solar panel charger, backup batteries, wiring, and mounting hardware. The type of roof, and its positioning in respect to sun are to be considered.

This blog is an introduction to solar panels and can assist potential investors in green energy a review on solar panels. Our approach is to discuss various issues related to solar panels and solar power systems for home and commercial establishments.


In our future solar panel review posts we explore more facts about renewable energy in particular to solar panel or solar power generators.
