Low voltage / LED / solar lighting circuit

[Idrisdraig]

I am looking for info on runing LED lighting for a small workshop from a combination of batteries and solar with mains charging power as a backup when the battery voltage is low and/or sunlight is limitted.
Ideally I'd like to run the lighting on a low voltage (12v ???) circuit.

Obviously it's technically possible, but I'm struggling to find any useful info on this. Is that becaues it just can't be done with commercially available kit. or am I using the wrong search terms in Google?

It can be done, but the problem is the cost of installation is far more than mains only lighting and any savings from using the solar power are so small as to be insignificant compared to the installation cost.

Instalation costs = £????.??
Labour costs for this project = £0000.00
Equipment costs = £????.??
Savings over mains = £????.??

Sanctemonious tree hugging sense of superiority = £priceless

Even that is not totally straightforward. For example, although they might not directly put many trees at risk, the battery(ies) (not required with mains lighting) alone have environmental and ecological consequences.

Kind Regards, John

as a rough guide a 50/50 5m strip will use 6amps at 12v so 5 hours will need around 36ah battery
that would give good light for a say 10x12ft shed
if you dont have mains look at say 7ah batteries or bigger if you can carry them

Did you try this or of search off grid lighting kits

Then just use the mains power you've got anyway, but buy the green stuff.

Shouldn't that be "buy the greenwash stuff" ?
