essegis: Thank you very much for this. All the locations are actually somewhat southwards but the car port is in the shadows of the main house till about noon when the sun is overhead and moves to the west. Car port will be installed next week and the slope can be determined with the least slope. however, that doesn't remove the shadows of the main house from it. Unfortunately for me, the sun's orientation and shadow casting is being observed for the first time now just over the past month, so I don't know what it will be like as the year turns round. One thing is certain, the BQ has no tall structures close to it and may be free of shadows all year round. I looked round other houses today in the area, and noticed their panels are all installed along that direction with varying slopes anyways. Thank you for the charts on wire sizing, it's quite helpful. I will drill the installers to ensure we get the right things, in case they aren't aware. |

essegis: This is a beautiful set up. I shall study the sun and the shadows for the next week or two. I don't have the luxury of space as my compound is quite tight. Looking at your set up, I may need locations both A and B eventually as my system grows. I am presently installing a 3.5Kva, 48v inverter with only 4 units of 200mAH 12V batteries and only 8 units of 250W panels to start with. I did enjoy about 18 hours supply but now dropped to 12 hours from NEPA. but e get some times when they just shut down for days. The frequency of such down times is increasing and that necessitated the inverter I never planned to have. Lol at main houses roofs like 2 storey building na so oh... Quite steep! � � |

Good days Gurus in the house, i am planing on a solar project for my home, but being a newbie i am some what lost on what might be needed and an approximate financial estimate as i wont want to be stranded midway into the project. below is an approximate list of essentials electronics load. 1. 3 pcs television 2. 2 pc decoder 3. 2 laptop pc 4. 4 ceiling fans 5. 12 energy saving light bulbs (10watts each) i will be very grateful if the Gurus in the house can help, thank and God Bless. |

korban3134: Ok I remember your original post from here: https://www.nairaland.com/390522/solar-energy-complement-fta/780#91115856 In my opinion, I think 200w on a single 200ah battery is kinda high load considering the inverter inverter charging current may not be more than 11A. Ok, you may need to borrow a clamp meter to check the charging current of the inverter. But in the long run I think the battery may have sustained some damage due to poor charging and the heavy load. So I may encourage you to either lower the load or upgrade the inverter and battery numbers.

mctfopt: Each tile is rated 30 watts, the voltage isn't indicated though. But it'll be interesting to know if the efficiency at 30 watts is as good as that from flat panels currently in use widely. |
Re: Solar Energy, A Complement To FTA by crowbar(m): 9:29am On Aug 01, 2020 |
Penuelseun:thank you for your response, but like i said earlier, i am a novice in this area, pls how can i check the rating, is it on the labels of my appliances or do i need an equipment or test meter to do that? thanks |

ceaser: Looks cool. If everyone substitutes their roof to this, that will be something |
Re: Solar Energy, A Complement To FTA by ceaser: 11:06am On Aug 01, 2020 |
crowbar: It is also written on the appliance, but those are not very specific and vary under different working conditions. The best way to do it is by using a wattmeter (kill-a-watt meter as some would call it).

kiekie1: Ado-Ekiti is certainly a long distance from Ibadan, it's better to get installer in Lagos than in Ado. However @ayinba1 if you need an installer in Ado you can reach me. I have an electrician who I have worked with over time for solar set-ups; I talk the theory most times while he does the practical and now does set-ups independently. |

The job is in Ibadan. Not sure what the distance is. I plan to buy some of the needed components that may need to be imported. So, if you and your electrician will take a job in Ibadan, add transport and lodging - email me so we can talk more. ojeysky: |
Re: Solar Energy, A Complement To FTA by ceaser: 8:51pm On Aug 01, 2020 |
Private hostel: ✓ 20 rooms self contained lighting point (approx 40 lighting points) ✓ Pumping machine 750hp (better it is run during daylight hours) - controlled by float switch and a timer so programmed. ✓ Charging points in the rooms (1 usb AC socket per room) giving around 5 watts x 20 rooms = 100 watts. I'm yet to determine insolation and sun direction and also the distance from roof to potential site of inverter set up. My proposal: • 60 amp MPPT (1 unit) • 10mm duo core • 320 watts mono panel (12 units) to be in 3s3p • Felicity 48volts 3kva pure sine hybrid with 60amp MPPT to take the remaining 3 units of panels. • 48v 100amp Lithium battery What d'you think sirs? 1 Like |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:08pm On Aug 01, 2020 |
ceaser: You did not indicate the wattage of the bulbs which will better inform on whether 4800WH will be sufficient backup. That said I don't think there is need for the bold, get the felicity 48v 5kva instead and run 3s4p instead, if the 48v 3kva felicity can do 3s4p then that will be cheaper option. |
Re: Solar Energy, A Complement To FTA by ceaser: 9:33pm On Aug 01, 2020 |
ojeysky: Thanks a lot I think the LED bulbs will be better pegged at 5 watts per room + 5 watts per bath and toilet. That makes 10 watts per apartment and 200 watts total. If more economy is needed, the bathroom lights can be pegged at 3 watts which will give 8 watts per apartment and a total of 160 watts for the 20 apartments. By the Felicity 48v 5kva, will it be bad if the 60 amp MPPT or it can still go as an extra addition? (I really won't like putting all the eggs in one basket of Felicity or one basket of another MPPT CC. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 10:02pm On Aug 01, 2020 |
ceaser: On the assumption that all lights and charging ports are used (which is unlikely), 200w plus 100w from charging points makes 300w and about 4.2kwh (14hrs battery backup) which is still within your capacity. However I will suggest 48v 150AH and 200AH if you have large budget.
The reality is that if the felicity goes bad, the external MPPT is also useless as well as you will still need to get an inverter. So I don't see anything wrong with using the hybrid for the solar completely. Based on your load, I also think you should be fine with 9x320w considering that lights won't be on during the day, pushing things to 12 units is just to cater for days sun is not smiling. My setup is 280x9 and I generate up to 8kwh or more daily (if needed) with same battery capacity as yours (though my nominal is 25.6v which is about 5kwh) and I think it should be same norminal with yours if it's Lifepo4. My load is way above yours during the day and my battery is 100% by most evening In summary, if the 48v 3kva felicity can accommodate 12 units go for that, if it can't go for 9units but if there is funds and you want to do the 12unit then push things to 48v 5kva which I am certain can accommodate 12units comfortably. Alternatively @Valto put a 3kva high Voc inverter for sale, if you can ensure no shading on the panels then go for that and put all the 9 units in series. 2 Likes |
