Compact is the whole pitch: HQST markets this 200W panel for Class B campervans, and the dimensions explain why. At 46.3 by 30.1 inches with a 1.2 inch frame it slides in beside a roof fan and leaves clearance for a ladder or a roof rack. The N-type 16-busbar cells reach up to 25.4% efficiency, which squeezes more watts out of limited area than older panel types.
The listing cites a 30-year output warranty, a long period that usually promises a gradual decline rather than constant output, so read the terms before banking on it. The IP65 rating handles rain and road spray, but it has no special shade design, so a roof fan casting a shadow will cost you output in the afternoon. It suits a van where you can arrange panels clear of the fixtures.
Two of these side by side make a 400W van roof, which is a lot for a single bank. Use sealed Z-brackets or an adhesive mount that avoids drilling the ribs, and keep a gap beneath for airflow. Compared with the ECOBOSS 200W it is smaller and a bit less shade tolerant.
