Nobody can tell you here as nobody knows the House and your specifications. Get some Companies to your House, explain all to them what you want and ask for a quote.
The NSAFD is a bunch of Fascists and criminals and soon get dissolved by the German Constitutional Court. With more than a smile on my face I donated some hundred Euros to an Organization of truly Democrats to push this forward.
Have 21 Kwp installed in three different directions and can extend the System by another 5 Kw, with the latest Deye Inverters you can have 130% of Panels installed as of the nominal Inverter size. For Panels I'm using 550W and 580W Longi Panels.
Have had a Huawei before as well, but kicked him out and got 2 x Deye 10 kw Hybrids and 3 x 10 kw LV Topsun ESS installed. Total price was much more less than for a Huawei Battery.
Air Asia offers Business Class as well and as far I can read they use Airbus A330 for the Flight from KL to Sydney. But most likely I will go for Thai as I want to get a non Stop Flight.
