Is a photovoltaic system also sensible in the west or east?

If photovoltaic is considered purely as a financial instrument, it can play a good role in an investment portfolio as a safe investment - just like other forms of investment. This modern, simplified either-or thinking under the microscope seems to be a sport.

Two comments from me on the calculation: 1) The high self-consumption is a special case 2) According to the calculation, the storage provides savings of €70 per year with one-time costs of €1500. From today’s perspective, amortization of the storage is therefore excluded. The storage is merely subsidized by the photovoltaic system and thereby worsens the account balance and the climate balance (manufacturing, storage losses). A lot still has to happen before a storage system pays off. Whether storage systems need to be kept at home is another question.

- a question, you have built quite large.. what level of self-sufficiency do you achieve? Could you provide some information on this?

Best regards

Sorry, I can't say anything about that yet. My system was completed in December. It was "commissioned" and reported operational in January, and I am still waiting for the installation of the bi-directional meter + generation meter. However, I expect a self-sufficiency rate of 50% and up. That is quite high for the average consumer, but two households are connected to the photovoltaic system here. In both households, the women are sometimes at home all day, sometimes from 2 p.m. That means I can basically schedule every laundry load, every dryer load, and every dishwasher load during the sunny hours. Additionally, I sometimes run a dehumidifier in the basement in summer, which I can of course also set on a timer to run during sunny hours, and in one household no electricity is needed for cooking during the heating period because there is a wood stove. For all these reasons, I assume that we will achieve a self-sufficiency rate of >50% even without storage.

I dared to order a 25.6 kWp system. Commissioning then in April.

In mid-March, the cabinet wants to discuss the future of the cap again and possibly adopt a transitional solution.

According to the current state of expansion, the cap should be reached no earlier than May. Factors such as the current weather situation and supply problems (Corona virus) are currently slowing down the expansion.

Is it still worth it? With the current price level, definitely (around 1,000€/kWp).

if you like, I am happy to share my calculation and regional providers

We have since had a conversation with a provider. That was very sobering. Offered only with storage and cloud. The feed-in tariff (which is already at rock bottom) would expire before we went online. So the electricity would be given away without storage. But that alone costs 10K.

We are now skeptical about this. If nothing happens on the part of the state, we will not be able to afford it.
