In brief
- A mounting crew's experience shows in pull-test records, anchor schedules and signed wind calculations, not in a panel count or a price.
- Ask for the fastener type, embedment depth and roof build-up in writing, then check the first row against that document before the rest follows.
- On a new roof, fix the mounting method at design stage so the roof build-up and the support loads are set together.

Solar mounting experience gaps in Burao can leave panel supports that look finished but do not hold. The gap is easy to miss because the array itself is visible while the anchors, rails and roof fixings that carry it are not. Owners and electrical supervisors can close the gap before work starts by asking for the records and calculations behind the support design.
What does a solar mounting experience gap look like in Burao?
It looks like a crew that can install panels but has never fixed supports to the roof build-up used on this project. Mounting work carries wind uplift, thermal movement and the weight of the array into the roof or ground. Salt, high daytime heat and dust may be part of the site conditions, and the project engineer should confirm which exposures apply and what they mean for the fixing detail. A crew whose experience comes from ground-mounted frames may not have set anchors into a concrete slab, a purlin or a masonry parapet. Ask the supervisor which fixing detail the crew has installed before, on which roof build-up, and for how many years it has held. If the answer is vague, treat the mounting package as unproven for this project and say so in the pre-start meeting.
How do insecure panel supports fail on a Somaliland roof?
The failure usually starts at the fixing, not the panel. Wind lifts the array, the anchor works loose in the slab or the purlin, and the rail moves. Water then enters through the disturbed fixing and the leak appears at the ceiling, far from the array. A support that is too light for the span can sag, crack the roof sheet or pull the parapet coping. Ask for the wind load the design used and the source of that figure. Ask the relevant municipal or planning office whether it holds any records for the plot, and ask the project engineer to confirm the design wind speed and exposure for the site against the project's specification. Confirm anchor type, embedment depth and edge distance with the structural engineer before drilling begins. Nothing in this paragraph replaces the project specification or the engineer's instruction.
How do you check solar mounting experience before you sign?
Check the record, then check the first row. Ask for a method statement that names the rail, the bracket, the fastener and the roof build-up, and for pull-test results or previous test records on the same fixing type. Walk a recent installation by the same crew, look at the fixings from below if the roof allows, and ask the building owner how the supports have behaved through a windy season. On site, watch the first row of supports go in. Check the drill depth, the anchor seating, the rail alignment and the clearance between the rail and the roof surface against the approved detail. If the first row does not match the method statement, stop and correct it before the crew repeats the mistake across the array. Write the fixing detail into the contract scope and check what your contract allows for inspection and hold points.
What to do next
Before the mounting crew starts, request the method statement, the anchor schedule and any pull-test records in writing. Ask the project engineer to confirm the wind load and fixing detail against the specification, and agree a hold point where you inspect the first row of supports before the rest of the array is installed.
Frequently asked questions
Can I check solar mounting quality after the panels are on?
Only partly. Once the panels sit on the rails, the anchors, embedment and roof build-up are hidden. Agree an inspection of the first row before the array is closed up, and keep photographs of the fixings and the drill depth.
What records should a mounting crew provide in Burao?
A method statement naming the rail, bracket and fastener, an anchor schedule with spacing and embedment, and pull-test results or references for the same fixing and roof build-up. Ask for these before work starts.
Who confirms the wind load for a roof array in Burao?
The project engineer confirms the design wind speed and exposure for the site against the project specification. Ask the relevant municipal or planning office whether it holds any records for the plot that the design should account for.
