Double Solar Technology™

Double Solar Technology™ (DST) is a technology that has been developed and perfected by Absolicon since 2002. Simply speaking, the idea behind the DST is to combine a Photovoltaic and Thermal Concentrator (CPVT) into one, thus, increasing the total energy output to 40-50%, as compared to a normal PV panel with 10-20% efficiency. Our goal is simple, to optimize the utilization of your roof space at a reduced cost.

How it works

The sun’s rays hit the solar collector that focuses and thereby concentrates the sunlight ten times on the receiver in the middle of the collector. On the outside of the receiver, special PV-cells are mounted that can withstand high concentration. The PV-cells in turn heat up, and in order to keep the cells at optimal production temperatures, the system adjusts the flow of the fluid inside the receiver to cool off the cells, thus producing both electricity and thermal heat.

The system also comes fitted with a solar tracking system that adjusts according to astronomical calculations. The tracking system also works as tool to control that the system does not overheat. When the incorporated temperature sensors reach a predefined maximum temperature, the system simply steers out of focus and thus cools off, and when the temperatures are OK once again the system steers the system back into focus again. 

Advantages

There are several advantages with the Double Solar Technology™ as compared to normal solar PV and Thermal systems, for example:

  1. Optimizes the utilization of one’s roof space, in terms of solar energy production.

  2. Lower total installation costs, due to lees piping and wiring and the fact that the system includes a tracking system, PLC, legs etc.
  3. Produces more thermal heat in wintertime, compared to normal thermal collectors
  4. Thermal system never overheats, thanks to the smart design of the PLC/tracking system.
  5. Only one single system is needed to produce both thermal heat and electricity.
  6. Lower environmental impact, according to life cycle analysis the impact is only ¼ compared
    to normal PV panels.
