Yes paying for themselves that's the down side I suppose.

I think you mean 2kW power output, 2kW per hour doesn't mean anything

It's how it's displayed on the smart meter IHD, I don't actually know what it means as unless it was very sunny every house I fitted a smart meter to still used grid supply

I had a small (1x1ft) solar panel that used to live on the roof of the landy and just trickle the battery, kept it topped up well until the local traveller contingent relieved me of it

What is the purpose of charging the bats?
IE, to keep them in good condition, to supply a light occasional load, to supply a heavy or long load?
Without knowing how much energy you will use its not possible to say how big a panel you want.
We have 1200watts on the roof. In summer they can produce 8.5kWh a day. In winter they make diddly squat.
This week the energy collected per day has been between 1kWh & 4.5kWh.
The 1200 watts can peak at nearer 1300 watts but not for very long as they heat up which lowers the output.

Those folding kiddies seem like the job.
The batts just need to be topped when there is no one on site, the site is run off a genny so no one there = no power.

You will also need a charge controller and there are cheaper non-folding panels about

We have 12 panels, 2.4kw peak... The most we have seen recently is 5.8kw/hrs over a day. A few weeks back. Wired 3 lots of 4 in series, outback mx60 controller...
An mppt charge controller is a must have item.

i use a couple of them for that
mysetup is 1x235w pannel 1 cheep ebay charge controller. was given the pannels by the contractor installing them and the charge controller was sub 50 quid off ebay. its just charges a couple of battery i had spare and it runs about a total of 8 mtrs of led tape when needed, if doing that you need a 12v regulator for the leds but they'll work without it i never botherd with one

We have a 3.7Kw array and our record for a 24hr period is 27Kw.
This will be our 4th year in July and so far our total is 13MWh.
Our 14 panels are divided into 2 strings of 7, each feeds into the solar inverter where the DC is converted into AC.

What voltage is your battery?
When you got the 5.8kWh what was the SOC of the battery at the start / end of the day?
