Cheapest solar panel kits, per watt
A kit bundles panels with the charge controller and cables you need to charge a 12V battery, so it costs more per watt than a bare panel. Ranked by kit price ÷ panel watts in the product name. Kits that include a battery are left out so the comparison stays fair. Bare panels: cheapest solar panel per watt.
