Photovoltaics - Questions about Tax/Business

Hello everyone,

we are planning a photovoltaic system with storage for our new single-family house. As far as I understand, I should register a small business beforehand, where I can declare the VAT/sales tax. I then have to report the earnings from the photovoltaic system to the tax office monthly, but I can reclaim the VAT on the acquisition costs and depreciate the entire system over 20 years.

We are getting the battery from Sonnen and signing a contract with Sonnen. Thus, the surplus will be delivered to Sonnen and remunerated. This should play a role, but I mention it for the sake of completeness.

Is that correct? Is there anything else I need to consider when registering the business, apart from being able to declare VAT?

Thanks

You do not have to register a small business. You can reclaim the VAT, but then you have to file a monthly VAT advance return and pay taxes on your own consumption. Battery from Sonnen... well, if you have money to give away and believe that the shop will still exist in 20 years.

The battery with cloud is nonsense. Put the money into more modules and fill the roof. That will cost you less and increase your profit instead of diminishing it.

You report your commercial activity to the tax office. For the input tax deduction, the small business regulation must be waived. However, the latter has nothing to do with depreciation.

Google this text (with quotation marks) and read the page completely: "25-30 Seiten kompliziertem Vertragswerk das dem Anbieter zahlreiche Rechte und Vollmachten einräumt".

Stupid question but is a photovoltaic system still worth it?? We would have enough space and money ...

Sure (without storage, without cloud crap), what are you waiting for?

That means? I feed in? To inquire about a tip?
