Recent shed solar panel install

[ericfx1984]

I recently installed solar panels on my shed the shed is really small about 5 ftw by 7 ft

I also built action effectively double d available space for solar panels

The plan is to have, 3 rows of 3, for a total of 2250 watts

Have you calculated the uplift force and leverage due to the cantilever at the top? You have a lot of cantilever and a very tall lever.

I will be less than a foot overhang on the east and west sides... But you are correct the bracket up on the top is quite a lever but it's not really a problem there's very little wind in this area and open back side as a lot of wind blocked on the back of it due to a bunch of cedar trees either way I've had no issue with having cameras just setting out so this should be fine. But I supposed to answer your question yes we calculated at one time and we were comfortable with it... My friend is an engineer who designs large sports stadiums and he did not seem to have any concern with the plan

In fact he said if the wind is bad enough to carry that away... But he believes I have other more important things to worry about

I mean when you consider that I've had two 300 w solar panels up on the roof of my RV or the last year or so and have them tipped at a 45° angle and made it through 60mph I'm just not too worried in that particular situation

Finally with the way this thing is locked into the roof and locked into the rafters.. it's going to have to carry away the entire shed before it takes these panels off

The other thing to keep in mind is that if the wind comes at it from the south it will have to lift and rotate the entire unit... Since it's less than 1/3 of the total length... Plus its going to be pushing down... So it's unlikely to build enough force

If the wind comes from the north there are many cedar trees which offers wind break... Even though the create a sail .. it would still need to push the entire unit into the ground or break the lean-to

The area you see right now is about 22 square feet... What's the additional panels are put on they will be mounted directly to the roof the total increase would be 62 square feet.. so really only 10 more square feet from where we are now

And the other panels that are being added or mounted to the roof they will only have about 11 in of cantilever

Bold. I like it. If something happens, it can be fixed.

One thing I have considered to strengthen everything up... Taking free holes on the north side of the building and filling them with concrete and sticking metal poles in them, been filling that up with concrete and bolting the holes to the bracket on the roof this would add quite a bit of strengths and probably be Overkill
