My wife and I recently bought a new house. Our neighbor has a very large 5th wheel that he parks in his back yard. It is positioned so that it reflects the afternoon sun onto the back of our house and into our living room. We never had a problem with it until he took it for a trip this summer. Despite ambient temperatures being roughly the same as the week before, our house was MUCH cooler and our air conditioner cycled on fewer times. I would estimate about 6-7 degrees cooler.
So I decided to do try and build something to block some of the sun. I though about using trellis to obscure it but that would violate city ordinance for fence height. So I decided to make something that could be put up and taken down easily. Besides that extra heat reflecting off the 5th wheel will save us money in the winter. :)
My solution. PVC and sunshade or screen material.
What you will need:
1.5" PVC pipe cut to length (hereafter referred to as a vertical pole)(I used approx 10 ft lengths, one pole for every 5 horizontal feet of shaded area)
1.5"PVC Slip x Slip connectors (1 per vertical pole)
2" PVC Slip x Slip connectors (1 per vertical pole)
1.5" PVC Slip Cap (2 per vertical pole)
Screw Eye Hangers (2 per vertical pole)
Sun Screen Fabric or Window Screening (I used a 6' x 25' roll of Sun Screen)
Wood Screws (2 per vertical pole)
Drill or drill press & drill bits
PVC Cable Saw (~$5) Not necessary but very convenient
Screwdriver (Phillips or Thompson depending on type of screws used)
