A solar panel review provides an understanding of factors involved in investing in green or renewable energy systems. With major players entering into 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 panels and supporting accessories.

3- Technical knowledge and skills.

We would cover these areas in various articles to help you in your project. Economics of the system discusses the cost, geographical location, warranties, etc. The efficiency of the photovoltaic (PV) devices 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 PVs. In comparing these, 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 of a PV, 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 type is called mono-crystalline. 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 are 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 boards, 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 article 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 articles we explore more facts about renewable energy in particular to Photovoltaic power generators.

In the hope that one day, our sun can warm us all:
