We've been going slowly at this, but have finally plastered inside and outside.

The next important step - and I really need some expert advice - is how to close the space between wall and solar panels.

I'm inviting, in no particular order, spyder880 mufutau55 skimanski abdulwastecx EgunMogaji mavverick segcymoor erico2k2 n3xt FastShipping segzy14 KolaShangOne and more to please lend me their minds for a few minutes as to how to solve this issue.

I really didn't want to use traditional wood, because I think steel and aluminium would do the job better in terms of stability, ability to deal with panel weight, as well as longevity. As a result, I'm in this quandry, as I am loathe to start hammering nails into metal. I initially thought we could just apply plaster and fill up the holes, but that would leave the beams exposed, which can allow water to trickle inside.

I've considered true2home's advice that "a light weight parapet will work. The only obstacle will be that the panels will have to be removed to allow for the parapet crown around the perimeter of the wall, then the panels can be lay inward by sitting on the top of the wall, not the top of the parapet."

Wish I had considered this part earlier before the panels were placed, but is that really the only solution, that we have to remove the panels and (essentially) start all over? I was thinking of nailing 2x2 wood all around the top wall,right underneath the panels and then using that as a base to attach fascia planks or a foam parapet that can later be sputtered with plaster...

Any thoughts please, as the lack of fascia is letting a lot of water into the building when it rains.

The spiral staircase that inspired our design, and the fabrication. Our welder/engineer did a fantastic job to create a minimalist, yet safe spiral staircase. All the rungs are properly spaced, angled down at 1-2 degrees to run off water, and the supports are not visually intrusive.

By the way, we're already producing an average of 30kWH of energy per day. This means we can keep the lights on, charge our phones and laptops, as well as run an efficient fridge indefinitely, without caring about PHCN or fuel scarcity. I personally designed and manufactured the highly-efficient (prototype) LED lights we're using, and I'm proud that they've run without issues for weeks now.

(I'll post pictures soon)

You may want to try using Aluminium fascia cladding used in one of our project in 2012.

However, you'll need to ensure it was properly attached to the trusses and the wall to prevent water from entering the building.

You can actually do an aluminum cladding and external ceiling with aluminum. Eaves angle at the top, use 2x3 wood to run the nogging. You can drill a hole in iron and then drive a nail with washer to hold iron and wood.

OR

Use light steel angle iron to to the nogging and them cover with aluminum.

This looks like a good idea... I'll give it plenty of thought and consult with a pro on the ground. Thanks

Preparing the H-beams that will support the panels. Each of the 5 beams is supported by 6" legs that will be put into the hollow blocks. Then we pour cement mix into these holes to hold the beams solidly. The beams are all angled 5 degrees from the front of the building to the back, which aids in water runoff.

Please what is the dimension of this H-BEAMS (length & thickness) and how much do they COST?

Tnx.

The beams you see are 22 feet (we bought 6 20-foot beams and cut the 6th into pieces to weld unto the other 5 and for the legs). 150mm wide. My records shows we paid #15.5k per beam in Delta State (includes transport). Labour to cut, weld, and paint the beams was extra.

Thank you for your response.

Would you be aware of the "thickness" (not Width/wideness! ) of the beam?
I am referring to its "thickness", if you hold a 'flat side' of it with your "thumb and fore finger"!


Tnx.

Good idea!

If it were me, l would use A Power Drill to make/drill holes in the Aluminium part of the Solar Panels and use Aluminium Screws to bolt the whatever l need to "nail" to it, after plugging plastic holders into it.

I sometimes wonder how a house built with concrete burns so robustly in Nigeria...[/quote]
Boss!!! I hail o!
If my memory serves me right, the American building code's factor of safety and load allowances are higher than the British which we were using . So, their structures are usually more robust. Sharp practices don't help too.
The idea of what works too is detrimental too. People can latch on to the idea that something worked somewhere without thinking of /knowing the thought process behind such decisions and they just copy n paste.

[quote author=nextstep post=The site we have planned has a very deep water table, and in fact, it's very difficult to reach it with a borehole. It's also on relatively high ground, and during the rains, water flows away. Why use foundation techniques designed for Lekki and PH when we can put the foundation right on the ground? Especially when the slab size is planned to be only 6m x 6m. I can't find it right now, but I thought someone on Nairaland did something similar...

Great thinking Sir ! Sorry, I'm late here,but what if for some reason drains around your area gets blocked and flooding happens for say just 1hr after some heavy downpour like u have in gra Ikeja n some areas in Surulere? Some of these things are based on factors of safety, in such an event the man with 1 course of block around perimeter is not at peace as much as the man with 3 courses of perimeter blocks is. People throw things indiscriminately into drains here, some even build on them.

Hello, how much did you spent on panels and what's your total square foot?

Each panel was about #80k, and I bought 28 of them for a total of #2.24 million.
The dimensions of the building is 400 sq ft (20ft x 20ft square), which was covered by the 28 panels. Each panel is about 5.25ft x 3ft.

As arranged, we have 7x3ft = 21ft in rows, and 4x5.25ft = 21ft in columns. This way there's a 6" overshoot on all sides of the building.

The company I got them from is Solynta ( http://solynta.com.ng/ ) which is owned by Nairaland user barcholder https://www.nairaland.com/barcholder

It's an excellent solar products company that provides outstanding customer service, and the team that installed our panels, batteries, wires, etc. were very professional. They were also willing to learn and work with us on this original roof design which had never been done before.

They also offer a payment plan so you don't have to pay upfront for an entire solar solution.

Sorry I did not read through all your thread. But why does the panel have to be on the roof? There is a general misconception that panels have to be on the roof to perform well.. which is not always true in fact ground mounted panels (if u have a shade free space to mount them) out performs roof mounted for the following reasons:

There are more efficient: One of the biggest causes of power loss on a panel is heat. in fact the higher the temperature is about 25c the less efficient the panel is. Mounting panels on the roof allow it get really hot has heat from the roof is transferred to the panel which can reduce efficiency by close to 40%. this losses also occure when you should be getting pick sun harvest. Ground mount though have less problem with heat. they are easily cooled by natural breeze due to the allowance between panels and ground.

Ground panels are also much easier to maintain than roof mounted panels: the dust situ in Nigeria means u have to clean ur panels at least once a month. For an installation of your size, that means having someone do it for u (more overhead) but a ground mounted system is much easier to clean. heck on a very hot afternoon you can easily hose down the panels with water. (I did and got almost 10% increase in my yield.

Lastly it is easier to achieve the right panel tilt and direction when there are ground mounted, there is that flexibility. Panels in Nigeria get their optimum yield when facing true south at an angle of 81 degree vertical tilt. This is way to mount your panel for optimum yield all year if you are in Nigeria. It is easier to achieve this in a ground mount than roof mount.

sizeof your PV means u can string them in series and have enough voltage to give u flexibility to find an ideal shade free space to mount the panels. the high voltage would help over come resistant thus reducing wiring loss and cost spent on wiring u.

if you have space around ur construction which are shade free then consider a ground mount. You can use this site to calculate sun path and shadows all year round which would help u simulate the best place to sight a solar farm. http://www.suncalc.org/

These are really good points, and after going through all this hassle, I totally concur. I have pondered dedicating a part of the site just to solar panels, and in light of what I'm experiencing - and your logic - I just might remount these panels on the ground. How would you keep them secured to the ground so they don't develop wings and walk away? Weld them?

I don't have a traditional roof, so I thought I'd save money by making the panels the roof (note that there is no traditional wood and sheets roof on this house). I was also going for the "wow" factor of having a radical type of roofing, but what a pain in the ass it's been.
Re: Building A Solar-powered Hostel - A Learning Experience by bigrovar(m): 4:46am On May 29, 2016
Just get a wielder to make something. You can also use wood. The wielder would use angle bar for the panels. It can be screwed tight to the panels to prevent flying. Check on YouTube too.

Learning loads on Nigerian context as it relates to solar on this thread.

I'm going to be having my solar panels on the slope roof of my North facing accessory building, so this is going to be interesting to get them facing South without looking grotesque (absolutely not having ground mount).

I'll have to add hosing down the solar panels to the list of tasks for the Mai Guard.

OP, I don't know enough to guide you on rectifying the roof issue. I would never use a solar panel directly as the roof cover.
