OT I know, but I have googled and can't find the information. I am trying to find the angle that is required for slats on a pergola to allow winter sun, but not summer sun. Outer South East suburbs
Melbourne. Hope that makes sense? Thanks in advance,
John

If I was at work I could tell you. Google anything to do with solar advantage/energy efficiency and you should find the answer.

Make them adjustable! Then you get the best of both worlds. Spring and Autumn can have extra warm days with sun lower etc.
Or look here

Mate of mine has an electrically operated vergola roof. Brilliant bit of gear! He lives in
Hobart ( up nera the mountain) where the weather can be challenging at times, even on supposedly fine days.
The fact that it can form a waterproof roof has saved many a bar-b-que from disaster.Effectively makes another room for his house.
(ps: I have no monetary interest in Vergola!!)

John,
This is the complete opposite of what your asking, but at the Hall in
Birdsville, they have erected awnings on western side of the hall, using "Zed" purlins as the shading material.
Lets plenty of light in, but adds a lot of shade, without "storing" the heat underneath. Don't know if you could use this idea at your place, with all the info you've obtained above.
Something on TV today about 6 star homes in
Melbourne, all very solar friendly.
Hooroo,
Bob.

Hi John, Just a different look at the same thing.
In
Perth, we have an outdoor spa with an open pergola, which we have covered with a Wisteria 'vine'. It grows a full foliage in summer giving us cover from the sun and loses its leaves in winter allowing the winter sun through. Probably a lot cheaper than movable pergola slats. You just need to keep it trimmed. It also looks good most of the year.
