Balcony power plant – with storage or without? Orientation?

I have now ordered a balcony power plant with 900 watts (2 bifacial panels), but without storage. If I notice that too much electricity remains unused, I can always buy a storage system later.

A good idea to start with. If you can time your consumers to run during the day, you won't waste much electricity.

We have now not consumed 151kWh ourselves according to the meter in about 11 months... is that a lot/little/normal?

I would say that is not that much. At 25 cents/kWh that would be about 30 euros in 11 months.

Hello,

in a private setting, one can almost universally apply the following simple rule for photovoltaic systems:

[*]Photovoltaic: As large as possible, all directions
[*]Storage: none

By the time the storage pays for itself, it is broken. Many charge cycles make it economical, but many charge cycles also cause it to wear out faster. It will probably take a while before the break-even point is clearly reached. Until then, storage is a nice hobby that gives you a good feeling of autonomy.

With balcony power plants, the situation is somewhat different. Due to the limitation of the maximum power, storage has a functional advantage. I can install more modules than the maximum allowed feed-in power. The storage acts as the buffer, the additional modules provide a constant supply.

Best regards

Hello, In private settings, you can almost apply the following simple rule for photovoltaic systems as a general guideline:

[*]Photovoltaics: As large as possible, all directions [*]Storage: none

I would no longer say that so generally. Although I built my system like that at the beginning of the year, the government has made these systems increasingly unattractive, so I don’t know to what extent that still applies for the future. 1.) Systems that were put into operation from the end of February can be switched off if there is too much surplus in the grid, and the compensation only comes after the regular 20-year period. If this happens frequently, you draw electricity from the grid even though the sun is shining. 2.) The compensation keeps decreasing, so that the remuneration hardly covers the self-costs anymore. 3.) In addition, there is currently talk of charging a fee for feeding electricity into the grid. That would also make storage even more attractive. 4.) Without storage, you cannot benefit from variable electricity tariffs like, for example, Tibber.
