Narrative: My mom had a shelter that was originally a sandbox. It was just about perfect for what I am trying to do, except it was in the shade.
The craftsmanship was pretty bad, but this shelter withstood hurricanes and weather for over 30 years. I took several pictures of the structure in hopes of rebuilding it. After playing with the design for several hours I figured out how the size came to be. He started with the roof, it’s in 2′ increments with sheets of particle board.
As you can tell it is two sheets of plywood per side. One sheet is ripped down the middle with a 2’x2′ section cut out of one piece.
The original design had a 2′ rise over 6′ distance which is an awfully large amount of stress on the truss with no vertical support in the center. I want to add 200 Lbs of solar panels and I want the angle to be equal to the latitude of Ocala which is 29 deg.
Given c=6 and ∠α=29°,a = 2.90886b = 5.24772∠β = 61° = 1.06465 radh = 2.54414area = 7.63243perimeter = 14.15658inradius = 1.07829
circumradius = 3
Raising the center will greatly reduce the stresses and give us the proper angle for the 600Watts of solar panels.
Need an unshaded area near the house. Trouble is all the trees are huge! The golf cart has 80AH at 48V ~4KW which is a tremendous amount of stored power. 600W of solar panels producing 3KW/Day is also a lot of power. (Enough for a small refrigerator.) But certainly enough to charge their phones and watch some TV.
