I have 40 1.8 metre solar evacuated tubes for hot water and at present 12 ,300 watt sunpower panels onto a 3.8 sunnyboy inverter straight to grid, I am soon to have 14 panels as temperature losses keep normal output below 3kwh.
I have read peoples thoughts about cooling and I tried just simple roof cooling but that was a waste of water and efficient.
But it did prove that on sunny days that were hot I was sustaining losses of over 1kwh.
I observed today how cold panels and a bit of sun shine make these panels about 110% of out put.
I have readings of 3.8 kwh on such days where one would not even think they would be ineffective.
I was thinking plastic containers that fitted onto panels underneath and spray mists of water inside and cool the flow on continuos cycle thus cooling panels.
But would sunpowered refigeration work better, the old type Kerosene fridge type .
It has to be simple and cheap surely such options are feasible.
From what I am seeing small solar panels are a waste of effort when heat losses would make the unit ineffective.
Full sun high heat, 2.9 kwh max, cooling effect 3.6 instant change.
The potential power gain on big solar collectors would be huge if panels were kept cool.
I was looking at large system of evac tubes and home made refrigerated aircon but could not get insurance on a cheap heap of second hand tubes to bring them home.
But such a unit would be more effecient the hotter the day.
could such a unit cool panels and do it economically.
