ThatFairGuy: Imagine this line of thinking @bolded. Pure undiluted tribalism, not for the sake of your tribe, but out of pure lust for power. Better IPOB, at least theirs seems defensive of their tribesmen. Tribalism is tribalism, though. But that of you uncouth Tinubu ers is becoming sickening. 1 Like |

Joylove2324: Hatred for Osinbajo? Me? ![]() Lol. You must really rate yourselves so highly. I don't feel hatred for him, please. Just disappointment. Tell him that's how Nigerians feel about him. I know you're his aide. Maybe he can still redeem himself... |

TheRareGem1: Same person as Joylove2324. Media assistants to Osinbajo. Go and tell him that we no longer have any belief in him or whatever he stands for. He has been given 8 years to change our history. But he chose to change his . Good luck to him. And Goodbye. 1 Like |

At first, they told us we needed a Sovereign National conference. At some point, constitutional amendment. Then GEJ held a National Conference, after which his government courageously allowed a little progressive change in the electoral system, and as a result of that change, lost power to them. They then ridiculed the National Conference to no end. They threw away the outcome of the conference, stated that Nigeria is okay as currently structured. That our only problem is corruption. That PDP's misrule for 16 years was our worst mistake. They said we do not need restructuring, that State Police is unnecessary. That our Police is enough. They defended Baba's 97%/5% policy. They made appointments dependent on what tribe's genes you carry. That merit doesn't matter when the President loves Nigeria, is well-intentioned, and is fighting corruption. At a point, an independent legislature became the scapegoat for our national problems. Because Baba needs the of everyone in government. Dissenting views aren't welcome. Today, Baba owns the legislature. Yet, for some reason, these legislators are still the problem, because they won't vote themselves out of existence. Now that it's clear that nothing is working, what do they tell us? That we need a NATIONAL DEBATE. Back to square one. National Please, how did they convince anyone that they'll be good for Nigeria? TheRareGem1: It's not a national confab. It's a national debate. We read that correctly. They are still trying to tell us another story again. ![]() Anyway, thanks for the attempt at clarification, but you cannot make addendum to Osinbajo's words seeing as you're not Osinbajo, nor are you his media representative. Or are you? ![]() 42 Likes 5 Shares |

LOAD. This means the electrical devices, machines and equipment plugged into the power supply. Think of the power supply as a donkey and the plugged in equipment as the load. If the load is too much for the donkey, it will collapse. And if you have just a little load, you don't need to look for the strongest donkey in the market. When all the equipment are plugged in and powered on, we say the circuit is on FULL LOAD. VOLTAGE This simply means the electrical force. It is measured in volts with symbol V, eg 12v. It can be AC or DC. AC is the type that comes from PHCN. DC is the type that comes from batteries. It is generally believed that DC does not shock in small quantities, while AC shocks even for tiny currents. But I advise caution with both AC and DC. Also, apart from shocking, there are several other risks associated with electricity which we'll do well to warn you of as we go. VOLTAGE RATING Electrical and electronic devices have what we call voltage rating. This rating describes the kind of electrical power needed to power the device. It specifies if the device uses AC or DC. It specifies the amount of voltage needed to power it. More on voltage ratings: To charge your phone, for instance, you have to plug your charger into the wall socket. This is because the charger uses AC. But the phone needs DC to charge its batteries. So the charger takes AC from the wall socket and gives out DC to the phone. So when you check the power rating of the charger, you'll see INPUT power and OUTPUT power. For other simple devices, they simply take AC and do their work. There is no output power. Take note of these small differences. 2 Likes |

In deciding what and what we need for our solar power, a number of things determine the kind of setup we do, chief of which is our budget. But keep in mind that as I noted earlier, solar power is accessible to everyone, not just the rich. I mean, everyone. Also, as we continue, I might be using some technical bogus-sounding which a number of us would be unfamiliar with. ![]() Not to worry. Ignore their big names. I would do my best to explain and break them down as we go. |

BaEnki: You would just need to buy an inverter with an inbuilt charger. You would simply plug in the inverter to the mains. However, you would need your electrician to ensure the inverter circuit is separated from the PHCN circuit. In everything you do, do not compromise your safety, please. NB: By mains , we mean power from PHCN. |

Elxandre: I will be explaining how to calculate your electrical load, so that you can on your own, make the decision according to your budget, and not depend on some professionals that are just out for massive profits. Just like in buying a car, you can spend 70 million, while another spends 400k. It's not really difficult, I assure you. |

Casemiro: ![]() Sure. Think of it like clothing. You can buy some for 500. Some cost 5k. Some cost 500k. Total even sells some solar devices for 12k. It all depends on what you want. Still laughing ![]() |

Casemiro: Your questions are welcome. It's fine. Solar power has many uses. I have seen someone set up a solar system just for his POS terminal and laptop in his shop. From what he told me, it cost him less than 20k. The cost of your system is determined by the expected use. The five components I listed is about everything you need for it. So, you can make adjustments to the capacities of each of them as necessary to fit what you need it for. As I have suggested, don't look for complete packages, especially if you are on a budget. Consider the costs, component by component. Soon, I'll explain how to make the necessary calculations in getting your components. 2 Likes |

feelme3: The rule of thumb is this: If more power is coming in than the one being used, the battery charges. If more power is being used than is coming in, it discharges. For instance, if I have a 200w solar and it is sunny, while I have a total load of 100w on, the battery will be getting more power than it is giving out. It'll be getting charged. If the total load is about 200w, it won't get charged, but won't get discharged either. But if the total load is about 300w, it will be getting discharged. That's the general idea of how it works. 9 Likes 1 Share |

Casemiro: I use monocrystalline s. They are actually more efficient than polycrystalline s. Though they cost more. I really have not looked into solar manufacturers, maybe because solar s have a long lifespan, as much as 25 years. I really can't check mine, cos I'll have to climb the roof ![]() But below is a picture of the solar controller I use where I am at the moment, somewhere up north. I use it with a 1200VA mercury inverter, a 100AH battery, and two solar s, each 18V 100W.

Now let us continue with setting up our solar power generator... It's time now to hang our solar s and connect it to our battery. The solar s need to be placed in a position where they can get maximum sunlight throughout the day. In that spot, there should be minimal casting of shadows on the . Also, we need to avoid placing them in positions where they can be tampered from time to time. This is why the roof is the preferred spot for hanging solar s. So, we carry our to the preferred spot and place it, with the dark crystalline surface facing up. We will then connect our cable ( the 16mm cables we purchased?) to run from the solar to the solar charge controller. Under the solar , there is a little box as in the picture below: There are two wires sticking out of the box, one marked (+) and the other (-). Connect the red cable to the wire marked (+). The length should run all the way to the solar charge controller. Then connect the other black cable to the wire marked (-). If both your cables are the same color, then mark the cable connected to the (+) wire. You can do this by putting a cellotape round both ends of the cable. This is important as we need to ensure we do not mix up the (+) point with the (-) point. Secure your in position so that it cannot shift or move about. A strong wire can tie it down or you use another method. This depends on your unique circumstances. Run the other end of the cables to your solar charge controller. Recall the six points indicated on the controller earlier? It's reproduced again below. Connect the red or marked cable to point marked 1 as in the diagram, on the controller. Ensure it is firmly connected, then connect the other cable to the point marked 2. Fasten it properly too. The solar controller is an "intelligent" device. It will automatically read the battery capacity and the solar ratings accordingly. The display on the controller should come up. You do not really need to change any settings on it. They're intelligent enough to make regulate your charging automatically. Now your solar generator is all set up. Enjoy.

Casemiro: A mono 100w solar might cost about N20k to N22k. A poly 100w , about N16k. I recommend looking up the prices on online stores before buying from our local retailers. And when checking online, ignore the outrageous prices some sellers put up. As for solar charge controllers, a 30A PWM solar controller should cost between N9k to N10k, or less. Don't pay more than that. |

Back to our solar generator set up... After connecting the battery to the solar controller, and the battery to the inverter, it's time to test the connection. It's simple. Just push the inverter power button!! The power indicator on the inverter should light up. Plug in a phone charger on the socket at the back of the inverter. The phone should begin charging. You can go ahead and plug in the inverter load selected for you by the electrician. The inverter is ready for use !!! One thing though - we are yet to connect the solar . You're almost through, though. ![]() |

greenhulk: While it sounds cheaper to get a 120k generator to power all the items you listed, you might need to sit back, and recalculate the real cost of running that petrol generator. I own a 4.4kw generator. While it can do everything you listed, I found out the hard way, that it did so at enormous cost. First of all, at minimal load, it consumes a liter of petrol per hour. With the utilities you listed plugged on, the consumption skyrockets. I know this because, mine runs my washing machine (LG side load machine, I believe it's power efficient), my microwave cooker, my refrigerator, lighting and fans, TV and decoder, and all other small devices like chargers. But I would also tell you that I really paid good money to keep it running. Petrol, engine oil, servicing, plugs, rope etc. At a point, it appeared we lived to serve the generator, and not the other way round. We would spend some nights in the dark because it was in servicing. I can tell you, without a shadow of a doubt that spending 250k on the solar power was one of my best decisions. For almost two years, I forgot I had a generator. PHCN filled in just fine. My brother, my brother, when you enjoy the convenience this system brings, you'll not turn back again. Even when we had just the petrol generator, we do not put it on just to run the refrigerator or washing machine. If we needed it, it was for lighting, the fans, charging our devices and watching TV. All those were additional benefits, which come with increased fuel consumption. On the other hand, with my solar power, I spent 250k and that was it. The only thing renewable in it was the batteries. After 2 years. If I spend 100k on that, it could take me another 2 years again without hassles. That's 350k in four years. 450k in 6 years. That's real cheap, bro. I chose to increase the battery capacity. To get my present system to run my refrigerator, I would simply buy a 3.5kva inverter. That will cost me 160k. Same thing your generator will cost you after 2 years. But while I'd go in and sleep afterwards, you'd be at the fueling station buying petrol. Lastly to set up a system to take all those things would cost me about 850k, assuming from scratch. If I decide to buy from China directly, it'd be cheaper. And I'll be fine for about 3 years. Then buy batteries for a cheaper amount. Because the cost of batteries will keep decreasing, not increasing, unlike the cost of generators. 6 Likes |

maxjax: It is quite workable, and can serve. However, it can only replace the inverter unit. You will still need the other components of the solar generator. Also, you will need to make certain adjustments to the UPS circuit, as it contains some circuit breakers and other such stuff. On another note, getting an inverter off the shelf is a lot more cheaper than this, and more effective. |

@agarawu23, @fashrola, the mppt solar controller works better than the PWM, and is actually more expensive. Ournolly chose to buy the best of what he needed. It could be his personal preference or as advised by his technicians. It will serve him in good stead whenever he decides to upscale his generator to say 5kva. So, at this point, I'm happy for him and pray he derives maximum benefits from it. We'll also appreciate it if he can update us with his experiences from time to time to guide most of us starting up on the solar journey. After his second year, he'll be the one dishing out orders to the technicians, I'm sure ![]() 5 Likes |

Now, it's time to setup our solar controller, inverter and battery. A typical PWM controller has 6 points as indicated in the diagram below. There are six points on the controller labelled 1 to 6. On the battery there are two points labelled (+) and (-). On the inverter, there are two points, red and black. Now do this carefully: Using the cables, connect, point 4 on the controller to the (-) point on the battery. Then connect point 3 on the controller to the (+) point on the battery. I'd advise you first connect the solar controller end, then the battery end. When you connect the second battery point, there might be a spark. Expect it. It's normal. Note to tighten the connections properly. Loose connections can cause partial , leading to power loss, battery drain and can damage your equipment. Next, we'll connect the battery to the inverter. Connect the red point in front of the inverter to the (+) point on the battery. Then connect the black point in front of the inverter to the (-) point on the battery. Double check that your connections are tight and not shaky. See below a picture of the recommended battery connection cables. 2 Likes |

After buying the equipments needed for the solar power generator, our next task is to prepare our home for the solar power system. We'll now carry out an activity known as LOAD SELECTION. This is quite technical, so you would want to hire an experienced electrician to do it for you. The objective is to select the lighting points, and the devices expected to be powered by the solar power generator. The electrician will open the junction box, identify your lighting points, fans, as well as designated sockets for the solar system. Those points will then be disconnected from the general power grid and rerouted towards your inverter. They are all to be connected to an extension head that will fit into the socket behind the inverter. You can check out the inverter picture in my earlier post for reference. Very important: The sockets selected should be clearly marked. Every member of the household should be made aware that on no is any high power appliance to be plugged into those sockets. For the purposes of our low-budget generator, only phone chargers, laptop chargers, or clippers can be plugged in. In fact any other device with a power rating above 10w should not be plugged into the socket. If there is any doubt about the power rating of the device, don't plug it in. Plugging a high power device on the system can lead to burning of the inverter and reduction of battery life. 5 Likes |

Ournolly: Congratulations on crossing over to the league of independent power generators/consumers. At some point, you would not understand it when people ask you, "you get light for your estate?" When I decided to begin using solar power, a friend of mine recommended that MTN solar device that costs 4500 monthly for 5 years. After looking at it, and seeing they were clearly ripping Nigerians off, I decided to explore solar energy on my own. The biggest impediment to having solar power was the tendency of the solar power resellers to place a high price on otherwise cheap items. They offered me a 1.2kva/100ah installation for 300k. I ignored them, struck out on my own and eventually set up a 2.4kva/200ah system, for about 250k inclusive of cabling and installation. These included two monocrystalline solar s of 250w each. The only extraneous cost was that of hiring a scaffold to take the s to the roof. When I decided, after two years to upgrade my batteries, I got two Viforce batteries 210ah each for 190k less shipping costs. That is 95k apiece. I have ordered for another 250w at 36k. Little by little, I can simply get another inverter, and add my refrigerator to the circuit. ![]() I have also observed these resellers servicing people's inverters monthly and I know they are just exploiting their customer's ignorance. In case you don't understand, servicing an inverter is like servicing a television. They don't need any servicing. This is partly why I am posting this thread. If people know they can generate their own power cheaply, we would be able to set off our own micro industrial revolution in Nigeria. Our offices, hospitals and schools will benefit. Our dependence on government for power will dwindle. Our homes will have cleaner air. Our night sleep will have less noise disturbances caused by petrol generators. All at a meager charge to our wallets. I wish you the best of luck on your solar power journey. Encourage others to hop on the train too. Hopefully, one day our country will be better than Korea... 29 Likes 1 Share |
