Pls what direction is best to place a solar panel?
Note: am not an installer just been curious.

You see am looking forward to even really talk about this thing.

Many people just buy panels and install, not all roofs are effective for solar panels, I mean not all slants are good for best or highly efficient conversion of power, some roofs are very slant that it’s almost that you can’t climb except you use a belt hold at locked at the top, (almost strait roof), but we see people place many panels on such roof, certainly it won’t convert effectively, only iff more panels are added to it or a better construction is done on the floor or on the roof,

Slants

Every slope position as an overall effect on the conversion of each solar installation, so there is an exact slope that gives most accurate or almost-best results ( luckily some roofs are just great)


Note: in respect to your the position of sunrise and sunset in the area

So while venturing into solar please watch out for your angles, for proper and efficient conversion.

Wow, I can’t believe it!

Someone should please run a test on this batteries. They seem too good to be true.

7.5kwh of lithium for 600k?

Anybody in the house using them?

GeorgeD1:


lolz. yes oh. I full ground remain, my brother.

and I can guarantee you that most other peeps you mentioned earlier are also around.
the fact that we don't post regularly does not mean we have gone away.
besides, apart from the marketers who make a living selling renewables, most other members
here have day jobs which keeps them occupied.

How is your solar system?

You really inspired a lot of us here. Even looking back at some of your earlier solar harvests today, is still breath taking.

I hope you haven’t given up on solar.

so, am planning ahead about building my house, am considering where best to locate the power room cum study in a duplex.
i am thinking of having an extra room in the duplex dedicated solely to power/inverter battery installations etc. and the space will also serve as my study. since am not sure yet of the type of battery i would be using, but likely 12 to 16 pieces or equivalent of 12v 200ah fla batteries, wi would think such weight would be better suited on the ground floor, and not subject the decking to the stress of carrying such a dead weight, however,..i would prefer my study to be upstairs, hence my dilenma. so hoping the house can throw useful suggestions on what they think is the best location with reasons.

thanks

If you must use the top floor then don't go for lead acid, go lithium and you will only need 6 to 8 200AH Lifepo4 and the overall weight will also reduce significantly.

Its better you have your power room downstairs, and separate from the building(power house).
Considering the type and number of batteries

Downstairs
Reasons:

1. Usually cooler compared to upstairs, unless you've got some bad ass roof design and ceiling that takes off the heat that comes from the iron roofing sheet.

2: Sturdier in terms of weight bearing.

3. In the event of fire, no one hopes for that, you'll stand a higher chance fighting fire on downfloor than up.





I'll suggest you create a small space downstairs for the inverter and other things. Then still have your study upstairs.

In this country its best to place them tilted towards the south. Your angle of inclination is also best if slight, let's say not greater than 15°.

I hope this helps.

Thanks for your kind reply

When you do analysis with numbers the crazy bot bans you. I don't even understand the algorithm that gets triggered by calculations.

I got banned here twice when I posted this-https://www.nairaland.com/390522/solar-energy-complement-fta/715#88405614 , had to resort to attaching a picture to get my point across.

Am trying to process this from the attached images I could reduce that:

1. The setup was 2x200AH which is 400AH 24V Lifepo4
2. At a nominal voltage of 25.6v that should be over 10kwh in capacity
3. At 90% DoD just about 4.4kwh was achieved.

So can we then say that the batteries are actually 100AH or at best 120AH each?

Ah, No oo

2x200AH is 24V 200AH or 4.8kwh

So the batteries are still in good condition under that load test.

Note: it's Lead Acid oo not LifePO4.

I don't understand that calculation Sir, could you provide further clarity. You got 2 units of 24v 200AH batteries and then connected them in parallel. That should give 24v 400AH

Edit: Okay I see you've updated to indicate it's lead acid test.

Impressive.
I also like the way you arranged the display meters.
Is there a way to connect a display to show incoming watts and cumm daily watts/harvest using a similar display?.
I finally installed the el cheapo Powmr CC and it only has instantenous watt display, no daily cummulative.

Also anybody using Makeskyblue CC?.
Does it display cummulative daily harvest /store harvest logs

Yes, you can connect as much meters as you need,

Just put Shunt in between Solar to the controller and/OR in between Controller and batteries, then connect the meters.

I know your mind is now set to LifePO4, you don forget we still dey use Lead Acid.

No worries, we go reach LifePO4 level sooner or later

For now Lead Acid will just do with proper and calculated set up.

I also Added 600watts panels to the mix.

Set up summary
Luminous 1.5KVA Solar PWM inbuilt
1140w panel (600 + 540 in parallel)
2X 200AH 12V (4.8kwh)

Makeskyblue shows the total harvest on the lifespan of the SCC. Eg today may start with 466kwh, at end of day you have 471kwh. That means you got 5kwh for that day No individual daily logs. Annoyingly, for Version 118 (dunno if they've changed it for later versions) you cannot reset this log. So you are forever stuck with the lifetime log, all you gotta do is subtract from old to get new SCC is just about $100. You can't get all 'em bells and whistles. Lol.

The 12v would have been of more use to me for Top Balancing. Too bad I missed out. Can you kindly share the link?

If you are still interested I can now sell the 12v I kept for myself

MakeSkyBlue displays the cumulative, which does not reset at the dawn of a new day. So it keeps accumulating until it gets to somewhere 9/9/9/kwh (not so sure right now) something.

The PowMr does not display cumulative. But it's cheaper than MakeSkyBlue now which is getting unbearably more expensive for an offering in that range, even for the fact that the two CCs are of the same form factor and similar performance.

By the way, did you just take delivery of the PowMr, ante-covid or it has been with you pre-covid?

idris4r83:
from my experience i noticed that only mppt controllers can effectively charge LifePo4 batteries. Pwm's dont charge them .

Pwm c.c charges LiFePO4 you'll need to do some adjustments on your charge controller then maybe your panels are also not sufficient enough to get it filled

Your normal 5 white bulbs, 2 Yellow bulbs and 2 colored bulbs, 1 Tv and 1 table fridge and 2fans.

Two 150ah batteries,four 150W panels,Hybrid 1kva inverter if your fans are not ceiling fans.This would serve effectively

She mentioned 2 yellow bulbs and 2 coloured bulbs. I'll wager those are incandescent lights like 100 watts each or at best 50 watts each. That's not to mentioned the 5 white bulbs she wrote which are likely CFL each likely 25 watts each - that makes 125 watts and then with the 4 incandescent bulbs (400 watts). That totals 525 watts on illumination alone.

525 watts will power 5 small sized deep freezers.
