Solar Film Panels
Many years ago, solar film panels were never heard of or available in the market place.
These new types of panels are the new wave of photovoltaic technologies that may someday replace the big rigid types of seen on virtually every installation nowadays.
The traditional photovoltaic panels typically sells for about $4.00-$5.00 / watt; not considering installation costs. The new thin film technology should cost around $1.00-$2.00 / watt. This is welcome news to those who want to install these systems at their homes and business because it makes them more economically attractive.
With the cost of a lower price technology, we can probably anticipate more and more homes to be powered by the sun. Just about every thing within the home can be powered by thin film photovoltaic technologies and be much more affordable.
Before rushing out the door to by a thin film system, consider the following. For the present time, typically thin film has one draw back. Its is not quite as efficient as the typical crystalline structure type that we have come to know. These panels usually have an efficiency of 10% or less, while the crystalline types have an efficiency that is in the neighborhood of 15% to 20%. But lately, improved thin film technologies are seeing efficiencies of 10% or more.
On the other hand, thin film offers better performance than the solid types where there are low light conditions. This means thin film will actually perform better than initially thought. It can provide more energy in these conditions than a solid crystalline panel and may be within the 15% efficiency range.
Thin film offer a tremendous amount of flexibility in placement on a building. The roof will no longer be the only place. Instead we may see thin film technology being used on the sides of buildings, in windows, awnings, and patio umbrellas to mention just a few. If a surface is directly in the sun’s rays, thin film technology can generate electricity for a building’s energy needs. Thin Film panels are light in weight, made of durable materials that are able to withstand impacts of hail stones. When in need of repair, replacement is easy and cheaper than conventional photovoltaic panels.
