_Basic Concept behind the Different types of Solar Panels
 
A solar panel is a collection of solar cells that are used to absorb energy form the sun rays, which can then be used immediately to power basic electrical appliances at home, or stored for future use. While each solar cell radiates a significantly tiny amount of solar power, several solar cells spread evenly over a large surface area can provide sufficient energy to power most household activities and electronic appliances. Needless to mention, because solar panel get power from the sun, the solar panels would need to be pointed directly to the sun in order to trap as much amount of energy as possible.
 
The Photovoltaic Panel
There are two main types of solar panels in use today: solar thermal collectors and photovoltaic modules. The photovoltaic modules are the panels designed to trap and convert solar energy into useful electrical energy that can power electronic devices such as computers, light bulbs in the house, TV, radio and sometimes even cars. Solar thermal collectors on the other hand are designed in such a way that they would absorb energy from the sun directly as heat energy, and are mostly used to heat water for basic uses at home such as showers.
 
The photovoltaic module is basically a collection of several solar cells which make up a photovoltaic array, or what is simply referred to as a solar array. The solar cells would be combined into a single panel for economy of scale and ease of use. Once combined into easily manageable solar panels, they would make them easily portable and would ease the process of installation. Besides, the electronics used to make them can be shared equally by several solar cells, no wonder they are the most economical type of solar panels available in the market today. 
 
The basic type of solar panel utilizes either very thin films made up of cadmium telluride or silicone, or they can utilize crystalline silicone in form of wafers. Once light from the sun hits the panel, part of the energy would be absorbed into the semiconductor, thus knocking the electrons free. The electrons would then be forced into a certain direction, resulting in a current that would be trapped and converted into useful energy.
 
With that being said, one of the concerns raised by consumers is how to make the most out of a solar panel from a small surface area. A solar panel as it is, is very expensive and would occupy a large space meaning it has to be not only economical in terms of space but also financially so as to make it a worthwhile investment at home rather than relying on other forms of energy.
 
While the consumer panels available in the market today operate at 20% efficiency, with the technological advancements in place, it is only a matter of time before they have a 50% and more efficiency, meaning the innovative solar panels that will find their way into the market would be able to trap and convert more solar power which can be used for a wide range of applications.
