Breaking with solar traditions since 2008

Radically new solar plant designs (#1): system X10

Solar plant designs are changing. They have to because the cost structure of today’s solar parks has changed. I’d like to contribute with a couple of new technologies that I’ve developed over the last couple of years.

You’re always very welcome to discuss these systems. Please feel free to like or share this posting if you – well – like it. You can also invite me to your personal LinkedIn network if you want to discuss these technologies personally. Please note: We do not produce solar products, e.g. solar racking systems. But we sell licenses to manufacturers and project developers.

Solar plant design #1: X10 solar plants

Adressed solar problem: yield losses due to soiling

This typical soiling phnomenon causes significant yield losses.

Most of today’s solar panels are embedded in aluminum frames. This frame triggers a significant problem when panels are installed at low slope angles (e.g. less than 20 degrees). The lower frame rail of the panel builds a horizontal raised rib at the lower edge of the module. This rib causes a back-water effect. The filthy water is not correctly run off resulting in the accumulation of dirt on the glass alongside the lower frame rail. This layer of dirt casts a shadow on the underlying cells, which often results in significant loss in yield.

X10 solution: rotate the panel, create a slope

Rotating the panel effectively ensures proper runoff of rainwater.

Our X10 solar system overcomes this problem in a simple, yet extremely effective way: By rotating the panel by a couple of degrees (e.g. 10 degrees) on its own plane, the horizontal corrugation disappears. The lower frame rails now both show slopes ensuring proper runoff of rainwater. The panel will remain clean, even at low slope angles.

Main benefits:

  • perfect self-cleaning capabilities for reliable energy yields
  • lower module angles for higher ground coverage ratios
  • off-the-shelf hardware, easy installation
  • reduced maintenance cost, lower electricity cost (LCOE)

About the X-panel technology: Please note that I publish my ideas only after having filed for corresponding patents. The patent for this technology is pending in the European Union, in the US, in Japan and in China. So please check with me and/or with public patent registers before using this ideas for commercial purposes.

About me: Although “inventor” sounds antiquated, it may describe best what I’ve been doing the last ten years. My solar patents are in force in twelve countries, with more patents pending, and a sketchbook full of ideas. Project developers have built utility-scale solar parks using these technologies, German solar racking manufacturers have signed license agreements. So far, so good. Now it’s time to roll out these technologies internationally. Together with the best partners.
