Just remember solar panel suppliers give the max and not average / normal power produced. A 500 watt array might therefore only produce 100 watts on an overcast day and 300 watts on a normal UK summers day. The 500 watts could be measured at midday in the Sahara !
What I'm saying is take the figure with a pinch of salt and go for probably 1000 or 1500 watts array if you reliably want 500 watts.

Thanks, I'm trying to keep within budget. I haven't got £500 yet. It would be nice to know what i actually get from them Real world advice is what helps with things like this and i have just found these guys. I'll put their links up in case anyone else finds it useful. Very helpful and they supply new and used kit to suit your needs, and local enough to me (Leeds) to go and chew the fat They advise spending money on a good charge controller (£260) then adding used panels in as and when needed. They reckon £500 would get a reliable and flexible 500w system, which would hopefully do the job, or can be added to later www.ebay.co.uk/itm/165W-MONOCRYSTALLINE-BLACK-SOLAR-PANELS-ONLY-59-/131893996459?hash=item1eb57eabab:g:8eoAAOSwUfNXSae7ianeenergy.co.uk/ |

I would suggest first giving all the walls and ceiling a coat of white paint to maximize the existing light.
Would a wind generator as used on boats be an option for charging?
Or perhaps a petrol generator to provide lighting and also power for tools

Yes a wind generator would be a good idea. At least to work along with the solar panels
I have a petrol generator but it's a bit loud to have on all the time

HI
i live in greece and have 7 x 240w sharp panels controlled by a 1700 w sunnyboy grid inverter
It gives a readout of power produced at the moment and over the day.
I rarely get more than 1000 w max at one time.
It is producing 10, kw a day at the moment about the maximum it will produce in full sun. I can change the angle of the array to follow the sun, up and down so monthly not round and round ie dayly.
I think your 500w system should produce
the wanted 1000w per day.
You can get an inverter that will accept both panels and wind together.
If you go for more panels later they must must be identical. Not only in Watts but type and make.
Adding dissimilar panels is like adding one extra flat battery to say a torch, what happens is the flat battery works like a big resistor. this is what dissimilar panels do.
