Jacque....Not sure what parts you are looking for...is it a project?
I am not sure which one you might be talking about. So sorry I can't help.
Contact the manufacturer, have the make and model numbers ready.
Do you want to buy and build a solar panel system?
Was it this project or something similar: https://www.hometalk.com/4120059/mason-jar-solar-light-diy?
If so, try asking directly on the post, in the "Questions" section, so the poster can see it and respond.
