If the bags are made from poor material and have poor construction, then they will not be able to withstand day-to-day activities and the outdoor environment. This will put your expensive electronic devices at risk. Moreover, this will place the solar panels at risk also since they will not be protected properly and there are high chances of malfunctioning.
Another factor to consider is the battery pack which is included in the backpack.
