My workshop is powered by a 80kw system with 3 phase inverters.
Anyway on seeing this thread I’d thought I’d post as I want to convert my house to solar using s/h cells. I’ve no urge to have my trousers pulled down by some package deal installers
I’m thinking of forklift batteries for storage. I remember at Fords a battery moving a 8 ton forklift would last all shift
My experience of forklift batteries is from forklift and tug operation and I like them@pressbrake1
this guy has been going for years using lead acid like what your thinking
this is more like forklift batterys
also worth a watch as uses both solar and wind power

I'm offering to help a member with my knowledge or ask the people who know
For information, typical second-hand ex-EV lithium battery prices:i know that lithium are the bees knees but at what cost, i was investigating battle born batteries, £881 for a single 100ah battery lead acid £70 for a 100ah ok you need 2 to compensate for the 50% depth of discharge limitation on a lead acid so its £881 for lithium or £140 for lead acid
The problem you will have is that on dark damp winter days the output from the panels will be a flat zero, or very near this. So how will you get over this? A similarly sized (to the panels) wind turbine would help, maybe a small diesel or petrol generator as standby?my original plan was to roof mount the solar panels on the stable roof that is on the left in this picture

i watched the sun today and although the roof is south facing it dident really get the full sun all day so my thoughts turned to ground mounting them that way i can make them face anyway i like, this expanded a bit more to mounting them on a turntable or pole that could turn and follow the sun, i thought about how to make the whole array follow the sun but gave up deciding it was far to complicated to track the sun i mean how would you do that .......... google is a dangerous thing lol turns out its pretty easy and if what i am reading is right you can expect somewhere between 20 and 40% more output from a tracking array, or 40% less panels for the same output
anyone got any experience of tracking arrays ??
It really depends on load, which is not really specified. Big flat batteries are no better than little flat batteries. A generator would be a must I believe.^^^ no matter what you need a backup generator, it's silly not to
other than that, 3 days storage worth of batteries will see you though all but the very harshest years
thank you, i dident realize secondhand ev batteries were so readily available they look complicated with a lot of connections and £4400 for ten is still quite pricey but way better than the battle borns at £8800For information, typical second-hand ex-EV lithium battery prices:

theres 2" polystyrene sheets
well i started with 100mm in mind but was talked out of that by a heating engineer who said 50mm will give the same insulation and the extra 50mm would be better in concrete to give a bigger mass to heat, its hard find out accurate information as everyone has different ideas, the ground under the concrete floor is about 400mm of tarmac chippings there is no water of damp there, but can change to thicker polystyrene if thats the way to go as the floors not going in for a while as i need the main field dry to bring a concrete lorry down with out sinking
