Just knocked this up bit of waste pipe and a 100w flexible panel I had spare
It’sWhere’s the pics Del???
Got to be honest. Monkey see, monkey do. Thanks so the support. Not sure if it will hold the panels upI was amazed at the difference between flat and tilted. When reading the post phil and rae did. So think if you can do it. Well worth the effort
Tracking the sun as well for best results.
But whatever latitude you find yourself in, Add 10° in the when the clocks go Fwd, Take away 10° from your Latitude when the Clocks go back. As a kinda guide.
Hi ya,Is there any mathematical basis for this?
The maths does involve latitude and time of year but is far more complex than this. The are many solar elevation calculations on the net, but I suggest that these are a bit much for our use.
The best performance at any time; any season and any location is to have the sun's rays hitting the panel at 90°.
So just set the panel so it points at the sun at midday. Repointing it every hour would be better but a bit of a chore.
For best results you need a swivel and tilt mount not just tilt. Maybe time to look for a discarded Captains Chair.
By the way mine is flat on the roof!

Mike Lacey got back to me. Just over £100 a pair for stainless. Half that in steel.How many struts for that? Did you try www.gasstrutengineering.co.uk ?
I must admit I like that set up. We'll talk later.Del just use an actuator like this and you can put it at any angle you like from the ground .I think it was only 35quid and 16quid for the remote View attachment 95401
No maths needed just point and play it’s as simple as that .Is there any mathematical basis for this?

Looking at the picture again Jeff, I see you are still using a gas strut or two.Del just use an actuator like this and you can put it at any angle you like from the ground .I think it was only 35quid and 16quid for the remote View attachment 95401
