Photovoltaics - Questions about Tax/Business

commission the system in January, you receive 20Y + the ongoing fixed remuneration

20 years the remuneration I would also receive in Nov/Dec, right? What changes in January? Does it depend on the size of the plant?

no no no... year of registration plus 20 years!

Oh, if I hypothetically put the photovoltaic system into operation in December, then the one month of December in the year 2020 already counts as the current year. They practically only recognize full calendar years. If I only connect it in January, then 2021 is the current year + 20 years of remuneration?

Exactly. Commissioning just before the end of the year is therefore tactically unwise. Of course, the feed-in tariff decreases month by month, i.e. I wouldn't postpone it by half a year for that reason. But that can be calculated.

You would have to calculate it. The remuneration decreases every month. Just calculate which is more worthwhile:
- receiving the higher remuneration for 19 years and 1 month starting from December?
- or having a lower remuneration for 11 months longer?
