Place I used to work had a copper shop, making electrical switch-gear for ships. they used tallow for spinning & drawing, butter for tapping, full fat milk for drilling, turning & milling (in summer the apprentice had...
You can stack them verticly (upside down so they drain) as long as you have a corner or a steel coloum to attach/strap them to, no need to drill or weld :welder:
Piped together it gives nice big reserve for a small footprint. :clapping:
I often wonder what these writers (& politicians) have betwen their ears, do they think there's a big tank where the grid stores all the "surplus solar electric generated midday in June for use at midnight in Dec ???
The problem with solar & wind is it tends not to be available when we need it...
Whit is 55° UNC is 60° so although they will go together if you tighten them up the contact line is so small the threads distort, such a combination only has about 25% strength of proper nut & bolt.
BA =47½°, mm = 60° so that has less contact area - think 10% of strength :o

Civil is the last word I'd chose to discribe war, but the pics are wonderfull.
Viability depends on your expectations of - avalabilaty/reliability of service, return on capital, conveniance of use (max generation is 10am-3pm), % of power actualy used,.....
Do you have figs for that, or is it just a gut feeling :dontknow::confused:
:doh: You can not conect a DIY system to the grid !!!!! It is dangerous to line workers & ileagal. (Heavy fine & disconection + posible prison if some one gets hurt :o)
Solar isn't viable without the FITs, end of.
tigler
The FITs are paid to the instalation so if you move in 5yrs there are 20yrs of garenteed income that you tack on to price of the house (& you get your cash back quicker). :clapping:
If you DIY, you can't connect to the grid & you can't get FITs :( so it will never pay back. :vsad:
Only partly, the fits payments are indexed linked to RPI/CPI =4% (Av30yrs) with electric fuel +1 = 5% but fuel prices are to volitile to be acurate long term
If fuel goes higher the returns get better :clapping:
NOT true :o absolute lies & rubbish :fighting:
Without the subsidies, a £10,000* 4kW system will pay back in aprox 78 yrs
Then you are into profit :whistle:
*(alowing that all component will have to be replaced 4 times)
:mad: :fighting: Not annoyed or offended :flame: but.... :laughing:
30° is good for South Spain
at Latitude 52 degrees a roof of 48 deg gives the best year round solar output
If you want to adjust the tilt of your panels four times a year, you can use these figures to keep capturing the most...
:hug: No probs, You are correct in saying south is generally best.
In UK 40° is the best roof angle, my system is on the w/shop roof @ 15° but still gives acceptable figs
:doh: Not true :o play with that calculator & see!!
you get a suprising amount from East or West, even on cloudy days, the panels work on visable light not heat, (in fact above 50°C they become less efficant).
A bright overcast day will produce as much as a hot sunny day :D
On my roof in Anglesey, I went for a 4kW system.
Acording to mates who've had these for several yrs, you generate 15-18% more than the local area estimate :clapping:
See-

just put your postcode in (you get more in...
