95% of everybody that is not a ritualist actually want Messi to win this one. Anyone who is against Messi winning this match is either a witch or knows someone who is a witch.

5kw inverter is the same as 4000w, so get 8KW or do 2 5kW in parallel.

after battery full, the energy from pv will power house load, so far your house load is not bigger that the available generated energy from pv

since the battery is already full, the inverter takes energy from panels to power house loads.

EPOMA:
You can make this simple , with a 15KWH if you use 1Kiliwatts per hour , that means you will get 15 hours of electricity out of it .

For inverter aircon, they consume on average 500 watts per hour, If you run the 3 aircon , that will be 3 times 500 watts = 1500 watts per hour, soon a 15 kwh battery , you will get 10 hours of electricity.

SINCE YOU PLAN TO BUY most items yourself, why not consider buying the lifepo4 cells from china and have someone build the pack for you for a small fee................or you buy the ready built packs by the guy in jos, his 48v 300ah pack was 1.5m last time i asked.

I believe the advise of DIY build is a good one, many users here run their system on them

1. The battery is direct from suppliers
2. You can add on it the BMS you like for your max. Power demand
3. You get to shave off extra cash and add to other items

On this you already got some decent advice/calculations from previous contributors. But let me add that you stick to 3-5w bulbs and for TV 25w or less. Also identify the actual wattage of the so called "inverter AC or heater". A heater is usually 1000w or higher, so what is the rating of the solar type. I would generally not use any appliance exceeding 80w on my inverter except when the sun is at its peak and my inverter on bypass .
Thanks very much for taking time to reply. @bolded.. really? But even inverter AC I believe is more than that. I am looking at a system on 15 - 20 KWh and the plan is to have at least 2 - 3 1.5HP AC on it.


The flatter the roof the better. A slight 10-20% inclination is desirable depending on your area.
However the "hidden" is a disadvantage, as the parapet will cast a shadow most hours of the day except at midday when the sun is directly above.
Also your building is skewed facing SW. But you want your Panels facing South for optimal results meaning your panel orientation will be skewed to your building when installed.
Lastly if your flat roof slopes to the back of your house, it means the direction of slope of your roof is counter to the desired inclination of your panels. So to install on that roof you need to design a platform for your panels with the desired inclination.

Hmm, quite true about the hidden roof. Though my own place is right at the middle of the structure (3rd House) so I am thinking it should have the least shadow impact. I may be wrong though, we will see how that goes.


A heater is usually 1000w or higher, so what is the rating of the solar type.
I do not think the Solar Water Heater uses any Power at all. This is why I have decided to go for Solar Water Heater. I believe the water is directly heated from the heat of the Sun and consumes zero electricity. That is my current understanding of it's operation sha.

The 20 panels is just a start, minimum to charge your batteries alone, considering your loads you will need. More panels. -300W + will be better

If you haven't roof your house yet kindly consider a flat roof this will be better for a solar install.

And plan ahead of time to get your plans scalable and flexible (since your loads, are not properly define yet)

earthrealm:
300 WATTS X 12 PIECES IS 3600WATTS, ASSUME 3HRS OF SUNLIGHT EVERYDAY, so you wud be getting approx 10kwh back from the panels.

the big question is your loads, kindly compute your loads , if your daily avg load is more than 8kwh, then you would be better off getting more panels...

is the setup offgrid?..no phcn charging??

Was waiting for this video of my mentor. Thanks so much for the link

Do yourself a solid, read the previous pages leading up to this one. You wouldn’t ask this question if you had.
