Opal Diffuser Canopy, 80 × 50 ft.
A designer steel canopy roofed in V-LITE® opal diffuser solid polycarbonate — a milky sheet that turns hard sun into even, glare-free daylight. The frame is iron square tube throughout: 2 × 4 in for columns and main beams, 1.5 × 3 in for rafters, purlins and the array sub-frame. Sixty solar panels sit on the east half in three rows.
What the model is built from
| Plan size | 80 ft east-west × 50 ft north-south4,000 sq ft covered. The 80 ft face is the south front, so the roof slope and the array both look at the midday sun. |
|---|---|
| Roof sheet | V-LITE® Opal Diffuser, solid compactA single dense polycarbonate layer with a light-scattering pigment. No flutes, no hollow cells - it diffuses rather than streaks, and it keeps solid PC impact strength. |
| Roof fall | 16 ft at the front to 13.5 ft at the back2.5 ft over 50 ft, a 5% fall into a concealed gutter on the north edge. |
| Primary steel | 2 × 4 in iron square tubeColumns are built up from four 2 × 4 tubes on a 10 in box with 1.5 × 3 lacing, and the main beams are shallow Warren trusses with 2 × 4 chords. That is how these section sizes carry a 16 ft bay - and it is what gives the frame its line. |
| Secondary steel | 1.5 × 3 in iron square tubeRafters, purlins, the west fin screen and the array sub-frame. |
| Solar array | 60 panels, 20 across × 3 rows2278 × 1134 × 35 mm portrait with 25 mm gaps. The array measures 23,155 × 6,884 mm - 155.0 m², 1,668 sq ft. |
| Array tilt | 22° facing southAt 22.72° N that is within a degree of the year-round optimum: about 100% of the sun on the panel at equinox noon, 92% in June and 91% in December. |
| Array position | Set to the east edgeA row of twenty is 75.97 ft, so it sits inside the 80 ft front with 4 ft to spare. The west bay stays clear opal roof. |
| Design moves | Fins, planters, concealed lightingVertical 1.5 × 3 in fins on the west elevation cut the late sun; linear lighting under the main beams turns the opal roof into a lantern after dark. |
Clear polycarbonate throws hard shadows and hot spots. The opal pigment scatters the beam inside the sheet, so what lands below is even light with no glare and a lower surface temperature.
Solid compact has no cells to hold dust or condensation, takes a tighter radius and reads as one clean plane from below - which is the whole point of a designer canopy.
Four 2 × 4 tubes laced into a 10 in box carry far more than one fat section, weigh less, and read as a slim shaft from across the floor. The hollow centre takes the downpipe and the cable.
Lifting the array on its own sub-frame keeps the opal sheet below continuous - rain runs clear, cleaning access stays open, and no fixing penetrates the weather surface.
