The reason of the high performance

In general it’s assumed that:

• The flat collectors are only suitable for low temperature applications.
• The high temperatures are reached by a high index of solar concentration through mirrors (parabolic (satellite dish) and tower technologies)

The alternative way to reach high temperatures is the decrease of the losses.The SRB Collector achieves that thanks to:

• High vacuum level.
• Selective treatment of high absorbency and low emittency.
• It’s for all this that reaches stagnation temperatures higher than 320ºC without concentration.
• It’s taken advantage of a high percentage of the diffuse light with concentration, due to the collector’s flat geometry (the parabolic (satellite dish) and tower technologies don’t take advantage of it).
• The advantage of the diffuse light makes the use of the panel suitable in regions of low direct radiation like many countries of central and north Europe.
