Last time I bought a panel from Lidl, it worked only on very sunny day. Very Strange.

Inspection revealed it had two 6 Volt 10 Watt panels in parallel and then 12V to 5V USB-converter.

When panels were reconnected in series it was quite OK.

What do you mean? Do you mean small solar panel for smartphones? Because the panels in the article are over a square meter big. Mine make 200-400 watts on sunny days

Yes. But 20W panel is panel too.

Little worried about Lidl-quality also on larger scale.

		Thats competly two different things. Different companies, different manufactoring methods and different components. The inverter is the biggest cost at normal PVs for example, the panel itself is glas and alumnimum and not epoxy or plastic.
