A7: No, we do not recommend connecting a CIGS solar panel with a 200W 9BB mono solar panel in series or parallel. As CIGS panels and Mono panels have a significant voltage difference, they cannot be connected in parallel. Therefore, it is not recommended to connect these two types of panels together. When connecting panels of different sizes, it is important to consider the voltage and current between them. Panels in series need to have the same or similar current, and when connected in series, the current value tends to be the minimum current of the panels. If one panel is blocked or damaged, the whole circuit will be blocked. Panels in parallel need the same or similar voltage, and a large voltage difference can cause a risk of burning off.
