I do all my searches manually and not that often so would be good to know if you can store searches??
Yes you can search FB marketplace, click search and enter what it is you are looking for and underneath it says "notify me" where you can "Get notified when new listings match your filters and search terms".

I think I bought them when PV efficiency was poor enough and PV prices were high enough but didn't get round to fitting them before PV efficiency was good enough and PV prices were low enough! :roll:

There were some hybrid panels a few years back which heated water and cooled the panels for max efficiency. Don't know if they are still available.
