Do You Leave Solar Power Lights Out In Garden All Year Round?
Yes, you can, but if you live in severe winter locations, I’d bring them in. Cold is hard on the plastics. And as said above, if you aren’t in the garden, why have them? Good time to clean them up and replace the battery….if you can find the replacement parts.
If you want a more permanent outdoor lighting, might be time to go with a wired 12 volt system.
E.J. there is actually a technical answer to your question. I’m leaving after this.
If the batteries are nickel cadmium, always leave them out never bring them in. If you do the batteries will suffer damage from non-use. If they are nickel metal hydride batteries (not really that common) then you can bring them in if you want to (your choice).
EDIT: Hey nothing like being “green” eh? We all put heavy metals in our gardens haha. How ironic. Nickel and Cadmium. Actually the cadmium is the culprit. Hahaha. Yeah ‘GO GREEN!” shhh! and then put cadmium in the garden haha so shameful.
The light manual should say, what type of batt is in there, or it should be marked on the light itself. I have cheap Chinese ones and even those say in the two page manual on them “nickel cadmium batteries”. Most are nickel cadmium.
You can do, but sometimes they’ll get condensation in them if they’re left out in really damp conditions.
If I were you I’d take them in when it’s too dark and cold to be out in the garden in the evening.
I understand your “Q” but would you stand outside in the Winter months with out the heat of the Sun? No to your question.
Most will not last 12 months anyway.
It rains here 8 months in the year !
How sad do you have to be,to own them in the first place!?
