ᐅ Photovoltaic system / heat pump – do you have two meters?

Hello and Happy New Year!
I have a question – since last October, we have had a photovoltaic system on the roof, including a battery storage.
Previously, we had two electricity meters: one for general electricity and one for the heat pump because of the reduced electricity rate.
Our electrician connected the heat pump’s electricity to the general meter due to the photovoltaic system, so we could see how this setup works and whether the heat pump benefits from the solar generation.
In December, we had a consumption of 700 kWh, which is quite high! Our general electricity use is usually around 250 to 300 kWh per month.
I understand that these are the darker months and it should improve from March, with likely much lower electricity consumption as the photovoltaic system generates more and the heat pump uses less.
How do you handle this – do you only have one meter now? Or do you keep the heat pump on a separate meter?
Thanks and best regards

I had an appointment yesterday with a solar energy consultant/salesperson. They said it’s fine to keep the two meters. Usually, it only makes a difference of about 30-40 euros per year.
Regarding the battery storage, they mentioned that you either install it right away or skip it completely. Adding it later is possible, but more complex and therefore more expensive.
I still need to research this topic more to fully understand everything.

Regarding the storage system, he said you either include it right away or not at all. Retrofitting later is possible, but more complex and therefore more expensive.
I still need to read up more on this topic to fully understand everything. If you go for storage, definitely install it now. We are still getting subsidies for that, 100 euros (USD) back per kWh (for us 1000 euros (USD) out of 5000 euros (USD) total).

The statement was that if you are going to install a storage system (if any at all), then it should be done now.
I don't think this was advice to get a storage system per se, but rather that if you really want one (for ideological reasons, for example), you should acquire it now.
