Very good results today more than enough power to run the cooler and charge the battery. Also prepared a video for the 2015 Hackaday Prize Semifinals Video. Particularly good as it is spring and the sun isn't at its seasonal peak clear day 21C max.
3 hours of sunshine got the tank down to 4C with improved tank insulation and storage capacity this is ample for reproducing dew-point conditions in the condenser.
In preparation of dew collection I've added an insulating coat for the condenser vessel.
My son 10yo is a big fan of the project. Also our dog Alfie.
