About Solar20 The Solar20 Project Our mission is to produce solar power at an investment of: 
To our surprise, our calculations show that it seem to be possible using state-of-art solar cells that operate with 20% efficiency at a light concentration of 20 times (20 suns) and a well designed mirror and mechanical structure. Designing a light and strong reflector has been our main focus, together
with a low-cost sub-degree tracking mechanism. We are doing FEM-analyse
together with Alfgam Optimering AB, www.alfgam.se
a company that since its founding in 1987 been active as consultants to
various companies worldwide.
Our concept is straight forward parabolic troughs in different scales and material. Basic elements are as below:
With 1 USD per W peak, electricity can be produced at 6-8 cent per kWh at good solar sites as see in the map above. To demonstrate our thinking we have build a first rudimental prototype with ALANOD sun reflectors and ANU Solar Cells. Prototype #1 - tested at Borlänge Solar Centre spring
2003 Prototype #2 - almost ready, final adjustments spring
2004 Prototype #3 - to be constructed autumn 2004.
How come this problem has not been solved earlier? Read the text “The Promise of Concentrators” under About/Reading to get the full picture. Sample ray tracing
