Solar Panels

The commercially available solar panels used in stand alone and grid connect systems currently are all based on silicon and can beclassed into one of three types, polycrystalline; monocrystalline or amorphous depending on the structure of the silicon used in the individual cells.

 

We offer Solar Panels made by BP, Solarex, Sharp, Kyocera, Siemens, UniSolar

Polycrystalline Solar Panels

Panels made from polycrystalline cells are the most common and cheapest. Well known brands include BP SX (formerly Solarex), Sharp and Kyocera. These panels typically retail at between $8.50 and $9.50 per watt. Under standard conditions their conversion efficiency of sunlight to electricity is 12% to 12.5%, which means that 1 sq. metre of panels exposed to the full sun will generate 120W to 125W of electricity.

These performance figures are for the standard conditions at which solar panels are rated and are rarely if ever attained in Far North Queensland. The most important difference is temperature. In the Far North on a sunny day, panels usually operate at a temperature of 50OC or higher, well above the 25OC used for the standard. The effect is that output is significantly reduced. A reduction of between 14% and 23% can be expected and this needs to be factored into design and costing calculatios......read more information

Monocrystalline Solar Panels

Panels made from monocrystalline cells have been widely used for over 20 years. They are typically used in high reliability applications such as telecommunications. Well known brands include BP and Siemens. These panels typically retail at between $10.00 and $11.00 per watt. Under standard conditions their conversion efficiency of sunlight to electricity is much the same as for polycrystalline cells.

However, they too experience a significant reduction in output at elevated temperatures, although the effect is not as large as for polycrystalline panels. A reduction of between 12% and 15% can be expected on a sunny day in FNQ and this needs to be factored into design and costing calculations..........read more information

Amorphous modules

Panels made from amorphous cells have been used in portable items such as pocket calculators for many years, but it has only been since about 1998 that they have become available for rooftop applications in Australia. The best-known brand is UniSolar, which retails for about $10.00 per watt.

They have recently become very popular in FNQ, because unlike the other types, their output does not decrease in elevated temperatures. Indeed, one independent test showed a slight increase in output. This means that the actual output is likely to be close to the nameplate rating.

Their conversion efficiency of sunlight to electricity is 6.3%, about half that of polycrystalline or monocrystalline panels. Thus an array of amorphous panels will require about twice as much roof space as an array with a similar rating using other types of panels. This can limit their application when the amount of unobstructed roof space is limited...........read more information
