Winter morning in north-eastern Europe: a solar fence steams while thawing (infosec.pub)

To make no excessive claims, I have to admit I burnt a fair bit of wood during the night. In the morning however, around 9 o'clock, the solar fence (nominal power 2400 W) was giving 600 W and steaming vigorously. By 10 o'clock, it had thawed and gave 940 W. Later, other panel arrays took over and wattage decreased. The energy was used to run a heat pump.

P.S. Knowing that server resources aren't infinite, I hosted the image externally, I hope that hosting on "postimages.org" works smoothly.

Your intake of solar is quite low

I have other solar arrays besides the fence. Two diagonal arrays and one shed roof (which covers with snow in winter). All together they can currently give 4.5 kW. But this never happens in winter, of course.

If you cool something considerably below room temperature (specifically, the "dew point" at the air moisture level that you have), condensation will happen for sure.

I use my heat pump for cooling in summer. The indoor unit keeps dripping condensation water through a small hose into the big water tank.
