GreaterFuture: For home, you can have 10 panels of 160watts each. That's 1.6kw. 2 big tubular batteries 240ah each. Big inverter and fairly big charge controller. Everything will cost over a million naira including fixing. It powers standing fridge and deep freezer (but you don't put on both same time to conserve energy). Televisions, home theater, decoder, fans, up to ten bulbs, blender etc. During harmattan, it can be on virtually 24/7. At night you leave only standing fans on till morning. Ceiling fans waste more energy. If you must use AC then you should buy inverter AC of 1.5hp. pressing iron draws a lot of energy too but you should buy inverter iron. However, to use both AC and iron effectively, you may have to increase the capacity to at least double of this i.e. 18/20 panels and 4 tubular batteries. Batteries can't take up so much space if you're living in a 2 or 3 bedroom flat. For office, it depends on the size. If it's just a single office, only 4 panels of 160w each and inverter battery of 200v can serve it. Then small inverter and small charge controller. Costs around 400k then. It can power basic things like two fans, a television, a decoder, laptop, and 2 bulbs till closing time. I understand that panels and batteries are more expensive now due to exchange rate. 2 Likes |

DryMouth:oga lumec is a power company on its own, their partnership with MTN was a low class version they were trying to use to get into more homes and business......they have other bigger sets.....I spent about 1.8M minus 100k for installation......you think it's the small panels that could only power one bulb and fan I will go buy for the whole house.....I had to buy those circular iron rods to hold up the solar panels then used the under as a shed for my gen.....they could not set it well on the roof, make them no go fall die for my hand I told them to install it in the compound. |

leokid866: Once in a while get a mop and bucket of water and clean the panel surface. Dust reduces the efficacy of the panels if left unchecked for a long time. |

leokid866: There are a lot of charlatans posing as if they know what they are doing. You have to research immensely to enjoy solar power in Nigeria. I have been using mine for over 5years now and apart from battery changes, the solar panels have been superb. I just got them cleaned last weekend to maximize my charging. 1 Like |

DryMouth: Solar panels are very durable. I have 8 panels of 300watts each and they were installed 5years ago. Once I notice a fall in the charge rate I clean the panels. Dust build up on the surface of the panels will reduce charge efficiency. 1 Like |

MrEverest: 20 x 160 w panels not enough for a/c load carrying. In fact, an average home needs about 20 x160w to run the home uninterrupted, unless you want to be turning off some things, while others are turned on. If you make it 10kw panels, you can run a/c and freeze to death if you like If u can run a/cs at night would depend on battery size. Its simple maths, available battery power divided by load = hours online. 2 Likes |

Decentlyproud: Both belong to the same lead-acid chemistry Gel, AGM are maintenance free until they die, as they are dry cells. Tubular require electrolyte top-up since they are wet-cells everynow and then. Who has time for that? Lithium is better than both, but way more expensive and riskier. Can burn down ur house if you joke with it. 1 Like |

Jennynexx22: 20 solar panels of 160w can easily power AC alongside other appliances in the home. 20 x 160w = 3200w or 3.2kw. You will buy an inverter AC, they have power input of 1.2kw. 1.6kw is enough to power every other household appliance comfortably such as freezers, televisions, fans, bulbs, blenders etc. Electric cooker and pressing iron draw lots of energy and should be avoided but you can buy inverter pressing iron, it's manageable. Also ensure that all your appliances are brand new or inverter for appliances like fridge, AC, Iron etc. You don't make use of second hand imported appliances that are not energy smart. Of course, nobody abuses solar system energy supply. So, you only put on appliances when they're necessary. For instance, you don't leave television on when no one is watching it or keep freezers on when it's already fully iced. At night you switch off all appliances not in use and leave only the AC or fan. Again, you don't use several high input ratings at the same time. E.g you shouldn't use AC, fridge and blender all running at once otherwise they will overstretch your battery. I have used solar system for many years so I'm talking from experience. 1 Like |

Jennynexx22: I switched to tubular batteries two years ago and haven't topped up the electrolyte even though I have it standby. The indicator is still on the green side. It's not like you change it every week. |

MrEverest: And me? I don't speak from experience right? 3.2kwp panels will not give you 3.2kwp on the dot in terms of power YOu're just doing divide and minus. Energy calculations don't work like that sir. Have you calculated for inefficiencies * 0.7? Energy Losses? Power factor of 0.8 ? Insolation? You'd be suprised that 3.2kwp will only deliver 2k+ish power at the battery terminals. Minus 1.2kwp from that and one slight cloud cover that last for a couple of mins; and your battery is in soup. You were just quick to respond. I said an `average home`. Why do i have to turn off the fridge/ac because i want to blend? Haba if you want to do off this, to use that, then after using this, off it, and on that. it's shitty An average home doesn't turn off the a/c or freezer just to blend. or turn off the freezer to use the washing machine. That's what i meant. 1 Like |

MrEverest: I never mentioned everyweek; besides you having them for 2 yrs don't mean they are better and should be recommended. I had 16x AGMs for 5 years, yeah u head right, 5 yrs in one bank; before a few of them started showing signs of degradation; so the whole pack had to vamoose. |

Rubyjade: You said in summary "dump pure sine wave inverters, go for hybrids" Aren't you aware that "pure sine" is a type of electrical waveform and thus, even hybrid inverters can be pure sine wave; or modified sine wave (a cheaper and worse alternative to pure sine wave) ? I am even yet to see a hybrid that is modified sine? Arent you aware that a hybrid inverter is simply an inverter + charge controller together in one? Instead of having to buy 2 separate units? thus the word "hybrid" as against "off-grid" or even "grid-tie" you were just mixing terminologies you don't even understand. 1 Like |

MrEverest:Ok.... For the first part, I would want something that powers all devices at all time, not doing permutation combination calculation, so as to manage energy.... For the batteries space, what if it's a duplex with boys quarters, duplex with up to 5 rooms. And say a few Shops... What's the battery space gonna be. NOTE: You wanna have power full power 24/7 without having to calculate what to On or Put off? (Sorry for the late reply) |
