Unboxing and Initial Impressions

The OptiSolex 400W portable solar bag arrived, and I was surprised by its compact size. Despite being a 400W panel, it's remarkably smaller than anticipated, easily fitting into a space comparable to a laptop bag. Its lightweight design, weighing just over 7 kilos, is a significant advantage compared to other 400W panels which often weigh close to 20 kilos. This makes it incredibly easy to transport and store.
