Air-water heat pump current consumption and data

Nice data, I can't compete with that. However, we had a monthly average temperature of a cozy +0.54°C here (own measurement every morning between 7 and 8 o'clock). In addition, several days of snow and ice on the modules, brrrrrrrrrr :mad:

Wow, there is a lot going on here.

It is May, something is growing but much too late. I brought my orange tree back inside, we had frost at night. Unfortunately, the leaves have turned white.

April was too cold and there was too little rain, the climate in this world is crazy, I honestly have a weird feeling.

For all interested, the total household consumption including heating, comfort electricity, and electric car for the entire April. A total of 1.1 MWh was generated by the photovoltaic system. The heating has been off for 1.5 weeks now :) [ATTACH alt="4117D759-121B-40C6-8BB5-8C03D5FA9916.jpeg"]60899[/ATTACH]

You seem to have quite a lot of sun, but why you don’t need heating remains a mystery at these temperatures. We still have well into the single digits at night and right now it’s 12 degrees outside. Of course, the heat pump will kick in eventually...

No problem, it's not a competition anyway.

It was already like this in winter that the house had a lower heat demand than others here. But we also notice the last 3 days without proper sunshine. Since the solar yield is the only heat source.

No, storage systems are generally not recommended. They are economically nonsense, as they are still far too expensive (currently about a factor of 3 away from profitability) and ecologically bad, because they have to be produced with great effort and the stored amount of electricity PLUS the charging losses PLUS the operating losses are not available on the grid to displace coal power.

Addendum (after my objection about the factor of 3 etc.):
In the overall ecological calculation, I agree that not every storage system has a good overall ecological balance (similar to e-cars). This depends on the manufacturers and, at a higher level, on legislators.

Couldn’t the charging and operating losses (depending on the storage-inverter combination, a few to (rather rare) double-digit percent) simply be combined and focus on the additional loss in the chain photovoltaic->battery->AC after conversion compared to photovoltaic->AC, since the normal case is direct consumption. So if 5% are additionally lost through the battery, that would be about 0.2 - 0.5 kWh, somewhere around 1-2% of the photovoltaic surplus in sunshine.

Regarding displacement of coal power: What are the exact numbers here? Large solar farms and still a majority of private existing systems do not use batteries at all: And private households can only store a part during sunshine anyway – so they will continue to feed in a lot – while at night they do not require the nighttime electricity mix (which still contains a lot of lignite and hard coal -> see live data).

So today is the day. The first complete 12 months with storage are over. Photovoltaic: 8.67kwp Storage: 6.4kw, since the end of March 8.98kw 191 charge cycles Of the 2093 grid consumption in the last 12 months, 1314kWh grid consumption are due to December/January because of the air-water heat pump.
