I buy some stuff from Harbor Freight but solar gear isn't one of them. If your intention is to have an auxiliary charger for a single (or possibly dual) battery system, when not plugged into the grid, 45-50w is in range. Solar Blvd has this 55w monocrystalline module on sale for $55. You could couple that with an inexpensive PWM controller for around $30. The total system weight would be in the range of 30-40 lbs., easily totable. Shop around for modules that are being sold nearby because shipping the large flat modules can get expensive.
Good luck with the solar charger, it is a great way to maintain your batteries.
