Solar setup for Floodlight

Hi,

Looking to install a couple of LED floodlights for a relative in some sheds. Basically he wants to have a yard in front of a shed illuminated during darkness (although I'd expect that activation with a PIR would be acceptable).

There are currently 50W LED floodlights in place running off a generator. However, the issue with this is that when arriving at night there is no illumination to access the shed until you are inside and the generator turned on.

Originally I had planned to use something like these which can be permanently on with low light, increasing to full illumination when the sensor is triggered. I have used these before and they are reasonably good for their price - although in the depths of winter they do run out of power:
(MPOW 54 LED Security Light)



However, the owner also wants security cameras installed. So, I was thinking if it would be better to create a battery bank trickle charged off a solar panel using some deep cycle car batteries. I would also put a battery charger across them too so that when the generator is going, it can top them up too.
I could then link a PIR to each of the pre-existing 50W LED floodlights and power them from the battery bank.

In regards to the security cameras, I've not given them an awful lot of thought as yet - maybe something like the Reolink Go PT - which is either powered by a rechargeable battery or solar powered - it can be powered by a 5V/2A supply according to the spec. Although I think the shed would require 2 - 3 cameras of sufficient coverage - so not sure how that could be done remotely and only require a single sim card.


Is this a viable plan or should I separate out both?

Think bigger.
Put big panels in the sunlight. Run off a single large battery. Use a charge controller with lighting controls.
If you can keep every appliance operating at or near the battery native voltage instead of an unnecessary inverter your efficiency will be very high.
