    Default solar panel frame build..

    hi i got to build solar panel frames for my roof its gona be a fix tilt.. got a question on size of material i should go for . each fram will holes a 345w panel but want to make it for 410w incase the future changes.
    so stainless is expensive but dream to work with and no rust coating needed
    Aluminum i cant weld have to bolt it but no rust coat needed
    then there is steel that after fabricated it i goto galv it.

    asking for those people you has build them before and learned which is better

    and size of metal needed i can calculate the lengths

    Just buy a mounting system from any of the major solar suppliers.

    They bolt together, no welding etc.

    Also looking at this and I'd say riveted aluminium would be cheapest and fastest and lightest.

    Adding panels to your roof is bad enough: adding extra frame weight might not be ideal.

    This extrusion in pic will work fine. Allow the extra 50mm in width and 100mm in length for the bigger panels. As the mounting in length is not at the end of the panel just allow for the extra width. Click image for larger version.

    @ 25kg each per panel excluding the frame, you really should check your roof construction.........

    Connect-it with 25 square tube. and rivet some angle to tubing frame which will hold the panel. Rivet/bolt panel to angle iron.

    Hinges on the one side of the frame and drop locks to keep down during travel

    roofs construction is 100%.. only downside is that we got slate tiles not the those ordinary tile so attaching to the roof is fun but i got plans to do that with hout drilling many holes but i was asking to get material sizes of what people are using .. so I don't over build it as I do with everything else.

    If you carefully calculate all material cost not forgetting accessories and consumables, then the ready made mounting systems on the market is not that expensive at all.
    Plus should structural COC, insurance compliance etc. ever come in to play, you'll be much better off with professionally designed and manufactured mounting systems.

    Exactly. This industry is now quite mature and there are purpose designed and made extrusions and fittings that really are easy and nice to use. Boer maak n plan solutions can cost just as much in the end and come back to bite you in the long run.

    Slate tiles I have done two installations.

    1/. Slate is removed where the panels go. Pic's attached. (Before and after)

    2/. Slate stays in place and holes are drilled in the slate. Pics attached. (the 5x3 arrays)

    East west works nice for home/residential use.

    I recently put up 6 x 330w panels (2mx1m), on a flat roof, I used 30x30x2.5 angle iron,,,with enough support/gussets sections I think I used 7x 6m lengths...lets say it's 6kg /length overall combined weight of the complete setup average 180kg that is spread out on 10sqm. I did keep the strength of the roof structure in mind and in the middle of the roof the wood beam rests on a wall - so that is the solid point - I worked from that as the frame lies with its center point on that beam, I further used anchor cables(electric fence cable) from each corner rawl bolted in brick wall - if the wind wanted to move

    In the past week we had a big storm with hail and the neighbor's 30 year old tree was blown over...my panels did not move,,,so I am happy.Click image for larger version.

    Very nice... I may move my panels in future, I just cant decide if its financially worth the extra few kWh of PV generated per month (estimate 10%) and my install will probably end up looking like yours.

    An issue arises when your panels do blow over, get damaged by hail etc. and you try put in an insurance claim. Then the structure is questioned, engineering signoff etc. At least with a purchased (and hopefully certified structure) one has some chance of winning the fight.

    If you not looking to use off the shelf mounting structures, use Unistrut.
    It is an approved mounting method for electrical equipment and is also galvanized, so should last a long time.
    The normal solar anti theft brackets also works great with these.

    When not mounting flush with the existing roof, please also look at wind loading.

    Look at www.valsa.co.za for mounting structures manufactured locally.

    See below ground structure from them I installed this week for a borehole.

    I am not affiliated or get anything for mentioning them.
