Old Solar Energy Bits & Bobs (Bellevue EH7)

Hello, I'm hoping to begin learning, and use solar energy at home and eventually, mobile in a camper van. If anyone has an old solar set-up, or any parts of one such as; a panel, battery charger, inverter, fusebox, cabling and any batteries, they would be put to really good use. Thanks in advance if you may have some parts or a system you no longer need.
