High power solar panels

Some solar panels are designed with a high efficiency but this is not always the case. Usually it is the expensive solar panels (typically made with multijunction solar cells) that are very efficient. If you research any affordable solar panel (like one made with crystalline silicon solar cells) you will find out that the efficiency is usually very low compared to that of a more expensive solar panel.

High power solar panels are those that are designed with a higher efficiency. Typically these solar panels have an efficiency of more than 20% which is definitely high. Some solar panels are capable of reaching 35-40% but in most cases anything above 20% is more than enough. Currently most high power solar panels offer you an efficiency of 24-28%.

The Design
There are various designs for high power solar panels but generally they are all made of pure silicon. The main difference in designs would be the layers in the cells. For instance, single layer solar cells are not very efficient as they absorb much less of the light available and cannot absorb massive amounts of incident light. On the other hand, if you look at multijunction solar cells, which consist of multiple layers (usually three), you will notice how much more effective they are.

Multijunction solar cells are definitely the way to go if you want the most effective option possible. These solar cells have the highest efficiency possible as they can absorb most direct light unlike some other types of solar cells. High power solar panels are usually made with multiple layers of solar cells and of those the best option is definitely the triple-junction solar cells as they cover all of the solar spectrum.

The Efficiency
The efficiency is what differentiates a low power solar panel from a high power solar panel. High power solar panels will have a much higher efficiency. Anything over 20% is definitely reasonable and if you are going to invest in high power solar panels then you will want to shoot for the best. Triple-junction solar cells deliver the highest efficiency possible with a University study having showed results of efficiency above 40% in some cases.

The main factor for how efficient your solar panel will be is usually the make up of the solar cells. If your solar cells are made up of a single layer then it allows for less light to be absorbed, and less of the solar spectrum. With multiple layer solar cells you will have different materials that are capable of absorbing different sections of the solar spectrum so you absorb as much light as possible.

The Cost
Here is the downfall for high power solar panels. If you want to have the best then you will be paying a premium price. The exact price for high power solar panels will vary by design and model but generally these will be the highest priced on the market. There are reasons for the mark up in price though.

Compared to cheaper solar panels which have a lower efficiency, there are many differences. High power solar panels are created with higher quality materials which are more expensive to begin with, not to mention the value that a higher efficiency has. In the future you may be able to find high power solar panels for an affordable price but at this time the performance of these solar panels are influencing a large price tag.

The Conclusion
After going through all this information there are a few things we can conclude. First off, if you are looking for the best performing solar panel possible then you will definitely want to check out solar panels that are made up of multiple layers. Also keep in mind that the multijunction solar cells (especially triple-junction solar cells) offer you the highest efficiency possible.

Secondly, if you are looking to buy high power solar panels then you might struggle to find a great deal but if you do decide to fork out the large amount then you will not regret it. Overall, high power solar panels are the most effective solar panels on the market today and they are the best option you have to choose from at the moment.
