Solar Panel Weights
Will I have to reinforce the floor when I put in a 300l/80Gallon(US) hot water tank?
Hi I’m think of putting in solar panels and I will have to put in a 300l/80Gallon tank on the second floor of my house. the problem is it will be resting on wooden joists and its about 1/2 a meter to a meter away from the brick supporting wall under neat will this be too much weight as i estimate in will be about 300kg when full will this be too heavy for my celling. also how would I go about reinforcing the floor if I ran a couple of thick joist along the floor would this spread the weight enough
I’m guessing you’re in oz talking kg and meters. If the centre of your tank sits 1/2m from the wall and the joist run the same way as that wall, you’d be sitting over the top of a joist more or less, just buy a 2.4m x 1.2m sheet of form ply 18/20mm cut it in 1/2 so it’s 2 1200mm square, put one on the other. If you slide the ply against the wall it will sit on 3 joist which will take that load easy.
If the joist run perpendicular to that wall just place that same ply over at least 2 joist and it will take the load.
P.S. I don’t believe you’d need to strengthen the floor because 300KGS isn’t really that much, but for the cost on a sheet of ply, I guess it’s better being safe than sorry
