Skinny Film or Crystalline Solar energy panels?


Thin film solar online businesses are dropping like flies. This coming year, companies such as Abound and also Konarka have gone bankrupt and also things do not look like they’re going to get much better. Crystalline section prices continue to drop considerably and European subsidies have risk. Despite these obstructions, does the thin film have a very future in the solar market? Should projects use skinny film panels? There is no evident answer to this question. Plenty of environmental factors go into the efficiency of solar cells. In certain scenarios, each technology has an advantage. In the end, it all comes down to the charge per watt. Choose the uv & solar window film.


To raised understand the solar industry’s circumstances, we first need to check out some general theories at the rear of photovoltaic panel technology. ENERGY performance depends on cloud protection, temperature, ground albedo, breeze speed, and much more. While using research last week I leaped into the following (very basic) equation:

P = Page rank (1 + (25-T)(C))(Si /1000)

where P is the result, Pr is the rated result at STC, T will be ambient temperature, C is a thermal coefficient and Evidentemente is solar insolation

Because of this relationship we can extract some fundamental truths about solar panels. Minimal temperatures and high solar energy insolation increase power production. Meanwhile, the more negative the C, the more sensitive to help temperature the panel will likely be. Unfortunately, the equation doesn’t give us the whole picture. There isn’t any way to see how absorption spectra or wind speed have an impact on performance.

From a purely complex perspective, the thin film features several advantages over different solar technologies. One of the main variances between the two major cell types is their winter coefficient (C). A thin motion picture has a much smaller value regarding C, meaning that its efficiency changes much less in response to heat.

Therefore, we can say that while building a solar plant inside the desert, this technology will probably have an edge. Absorption is a key factor in this argument. Thin film cells take in a wider range of mild, absorbing more infrared (IR) and ultraviolet (UV). The PV cells achieve this by combining many layers of materials with various absorption spectra. Together, the particular layers can absorb a lot more light than the crystalline mobile.

This gives them the advantage if an area doesn’t have consistent sun. Just because it is cloudy outside the house does not mean there is no IR or perhaps UV light to be gathered! Finally, they can also be “rolled” during manufacturing, which is an extremely efficient process, and do not will need mounting for installation.

Total thin film panels will be more reliable than crystalline, carrying out consistently under poor climates and high temperatures. However, technological innovation is not the deciding aspect when deciding to install any solar panel. Economics has the previous laugh.


Project constraints and costs play a significant role in designing any solar electricity system. The skinny film can only be used if you have enough space. A simple calculation according to panel efficiencies will show that will nearly twice as much room would be needed for these motion picture.

The extra land costs only may be enough to destroy any thoughts of using less efficient panels in many projects. An interesting point to that argument can be made for off-grid facilities. Since this picture is capable of producing electricity, not in good conditions, the technology could reduce the required battery standard bank size. This will decrease the expenditure and the space needed. Whenever you can still produce some energy on rainy days, instantly you don’t need as much storage. Normally the capability to produce electricity in poor conditions is crucial with large projects.

Another simple factor to consider is racking. Thin film panels do not need the special racking that is required for crystalline installations. They can be fastened directly to roofs and other soft surfaces using an adhesive. That brings down their installation fee and gives engineers and designers more freedom in buying a site or surface to get solar panels.

From all the information preceding, you may assume that thin picture panels are the cheapest available. Unfortunately, this is false. Si prices are so low this despite the theoretical advantage of this specific technology, crystalline panels master the market. Thin film manufacturers need to decrease costs to keep competitive.

There are two major ways to do this: expand production capacity or improve technological innovation. Both are very costly initiatives that may get companies in debt. R&D and new factories are generally not free. Many solar organizations have tried these methods. Abound stopped production through the first quarter to give attention to research and development, simply to go bankrupt recently. In the meantime, LDK Solar is $3. 4 billion in debt.

In theory, if a site has very good year-round insolation and sensible average temperature, crystalline is a reasonable choice. If the site will be large, hot, or overcast and there are intermittency concerns, the skinny film now looks like an even more reasonable option. You can think it over like this: the thin film will probably be better suited in deserts and northern regions although crystalline will perform well among the two extremes (unfortunately skinny film will have to compete with solar heating in deserts). While there is potential for both engineering, the thin film marketplace is going to have to somehow lower its cost to compete with transparent panels. It is still too soon to call, but you can find still a promising future for skinny film solar panels.
