# Make it Solar
The „Make it Solar Challenge“ represents the transition from laboratory prototype to real-world conditions.
As there are many designs and possible configurations for solar heat sources, we are trying to work out which configuration works best with Acraea. Then we initial testing, but also for later implementation for end users.
