End of December. Germany. −5 °C outside.
~3.8 kW solar production — and 1.2 kW going straight into the heat pump.

Not “free heating”.
Recycled sunlight. ☀️➡️🔥
No grid import. No battery cycling. Just direct winter solar doing useful work.

This is why cold, clear days are PV magic.

A quotation from Shakespeare

GAUNT: His rash fierce blaze of riot cannot last,
   For violent fires soon burn out themselves;
   Small showers last long, but sudden storms are short;
   He tires betimes that spurs too fast betimes;
   With eager feeding food doth choke the feeder;
   Light vanity, insatiate cormorant,
   Consuming means, soon preys upon itself.

William Shakespeare (1564-1616) English dramatist and poet
Richard II, Act 2, sc. 1, l. 37ff (2.1.37-44) (1595)

I did manage to get a crude pin-hole #eclipse pic and have so far steered the dishwasher around needing to #import from the #grid - #selfConsumption FTW

I did not get much done #today, but I think that that is OK for a Sunday! It has been sunny, I recovered from a slight hangover from yesterday's fun evening, and I did tweak a minor system parameter to improve #selfConsumption...
