Let's talk more about battery, this is where most people have problems. There are 3 types, VRLA, GEL AND AGM. VRLA or wet cell or flooded if you like, are batteries with acid liquid like in your car. These batteries require periodic maintenance, like toping up the liquid with distilled water. I'm not telling you to use vehicle batteries, these are a NO NO NO for solar. Your car battery is a cranking amp battery, meaning its made to crank out high amp in a second to start your car. You will notice that should your car fail to start after a few trials, the battery runs down. Though they are a member of flooded/ wet type, they are not made for renewable energy. |
Re: Let's Go D.I.Y On Solar by 3276reliance: 11:12am On Oct 04, 2016 |
GEL and AGM are sealed acid, no liquid maintenance required. AGM however is the latest in battery technology. As a starter, you want to look for AGM or GEL. Care must be taken not to charge these batteries with standalone "smart chargers". They are sensitive to overcharging. |

3276reliance:How do one get critical current to the batteries. When panels are installed on the roof or within the premises, questions are, Are the positioned in such way to capture the full ray of the sun, No matter the number of solar panel modules one installed, hence a little shed either from a tree or nearby houses, falls across the panels your absolutely getting little to nothing. It's like charging a battery on idling generator. Maximum sunlight is all about solar energy delivery. |

You can deeply discharge your battery daily but you pay a price of short battery life. To have a longer battery life, the lowest you want to go is 50% DOD ( depth of discharge). If you can do 30-40%, the longer your battery is going to last. Charging your battery back up to full state after every use is important. This is not to say you have to oversize your panels to make up for some days of bad weather as some will advice you to. If the weather is bad for a day, simply reduce your load, it will save you money, rather than generating power that you don't use on good weather days (of which we have more in Africa) from your oversized PV array. The choice ultimately is yours. |

indigene: Sorry bro, I don't get you, I can't see where I said PV should be under a shade. Thank you |
Re: Let's Go D.I.Y On Solar by 3276reliance: 1:20pm On Oct 04, 2016 |
Because proper charging is important, we sure need to talk more about charge controllers. I earlier said I prefer the mppt to the pwm even for small applications, as far as I'm concerned, PV array over 200 watts for me goes with an mppt, yes there are low Amp mppt like 10, 15 and 20 amps. You don't have to buy the more expensive 40-60amp versions for a small setup, if you need these low amp type, hola me. |
Re: Let's Go D.I.Y On Solar by 3276reliance: 1:27pm On Oct 04, 2016 |
Let's see this scenario, you have a 200 watts panels to a battery, the best you can get is between 60--70% with a pwm cc, and that figure is a few hours of peak period, plus your battery has to wait every time there is less than 12 volts from the panels early in the morning or due to clouds, pwm is the last to start and first to retire. Now you're thinking of adding a 100 watts panel to the system. I will rather buy a small mppt cc instead of another panel. The mppt brings a balance here. At peak hours, you're going to be generating up to 95-98% of your panels capacity. The most interesting part is that your battery don't have to wait for each panel to put out 12v to start charging. The mppt allows for higher voltage input which it converts back to amps going into your battery. Next we discuss wiring the panels with pwm and mppt to achieve different result |

3276reliance:But are you aware that a shade thrown across installed panels whether on the roof, or within a premise ground decreases their throughput efficiency? |
Re: Let's Go D.I.Y On Solar by Chrismanuel: 7:46pm On Oct 21, 2016 |
3276reliance:@ the op, pls ride on. the layman here is enjoying your tutorial. personally I have passion for green energy but I need to know the least amount I need to have to start enjoying the power of green energy even if its just for charging of my phones and one bulb |

Nice thread op |
Re: Let's Go D.I.Y On Solar by anu3: 12:06pm On Oct 22, 2023 |
Hi... I've been doing diy solar since around 2016 for personal use.. I could answer basic questions if necessary... |
Re: Let's Go D.I.Y On Solar by Noah13: 3:04am On Nov 21, 2023 |
anu3:I'm looking at a small setup to pay small devices like lights, a standing fan and keep phones & power banks up |
Re: Let's Go D.I.Y On Solar by anu3: 9:11pm On Nov 21, 2023 |
Noah13: Except it's a standing fan, you need a lot more to power a regular fan: like maybe 50ah - 100ah battery, small inverter like 500 watt, solar panel of around 100 to 200 watt, and a common charge controller. But with a DC fan you may not need an inverter... |
Re: Let's Go D.I.Y On Solar by Noah13: 11:02pm On Nov 21, 2023 |
anu3:it's actually an old standing fan from qlink. How much do you think all of these would cost right now? |
Re: Let's Go D.I.Y On Solar by anu3: 8:26pm On Nov 22, 2023 |
Noah13: Ok, it may have a 12v DC port to power it. I use a mobile table fan (bigger size) that use phone charger for now. 100/150watt panel should be around 30-40k... I only got a used 80watt for just 8k a few years ago—from a house agent. But it should be around 18 to 25 then. I just got a 380watt panel (55k, but some may sell it around 70k above) for some more serious use recently. But this time, I needed a charge controller, not a car charger. The panel is 30+ volts, it should blow off car chargers (12/24v) |

anu3: please bros hiw can i get a solar system to give me mini 4-6hrs at night... with a budget of N130 - N150k |
Re: Let's Go D.I.Y On Solar by anu3: 9:33pm On Nov 23, 2023 |
Immortal99: I guess you might need a bit more ... 100ah battery: 80k A single unit 350/380w panel: around 70k maybe 500/1000 inverter: 15 - 25k Charge controller: like 7-10k pwm type (but quality mppt type with better performance is around 40 - 60k or more) Lastly, wire... Modified If anyone sees something wrong, pls tell... |

anu3: Thanks bros.. what of a solar generator i can charge with nepa..that can power my pc for 8hr min non stop |
Re: Let's Go D.I.Y On Solar by anu3: 2:53am On Jan 07 |
Immortal99: Not sure if you meant a laptop, the set up above is fine. To charge with nepa, I bought a 20a battery charger, good with 100a battery... Note: I usually order such things from jumia, so the last time I checked that battery was no longer 80k but 105k... |
Re: Let's Go D.I.Y On Solar by anu3: 2:57am On Jan 07 |
Immortal99: Not sure if you meant a laptop, then the set up above is fine. I think... For a desktop, well maybe 3-4 hours, not sure. Someone used the setup to power a big freezer for 3hours... I read that on customer review... To charge with nepa, I bought a 20a battery charger, good with 100a battery... Note: I usually order such things from jumia, so the last time I checked that battery was no longer 80k but 105k... |
Re: Let's Go D.I.Y On Solar by Immortal99(m): 9:41am On Jan 07 |
anu3: Thank you. I was looking for a portable solar generator that has everything ... just to add panel .... I move a lot ..so i prefer portable things |
Re: Let's Go D.I.Y On Solar by anu3: 1:10pm On Jan 07 |
Immortal99: Then I think you need a laptop power bank. I think you find some on konga/jumia. There's also a seller know on this platform. But you must be willing to pay upfront before shipping... **The inec type: small and big sizes. Your type of need should go for around 150k (8 or 10 hours). Or 100k for 4 - 5 hours... But I prefer using platforms like jumia/konga these days. Cos you could possibly return your item even by merely changing your mind (jumia). Not sure if there are many regular sellers like that. I first got a small power bank from a seller here... Nepa and Sunlight have been regular for a few months now, so I've not been using that new battery I mentioned very much. Cos Nepa and my new 380watt panel have been doing well with the small powerbank. But later during rainy season, there maybe less nepa and Sunlight... |

Re: Let's Go D.I.Y On Solar by JMonster18(m): 8:26am On May 20 |
Hello, new to the thread here, i'm thinking of setting up a solar connection just for computer setup (not connected to the house). I'm assuming 18- 20hrs of power without nepa power supply and on a full charge. This is my plan below 1x Gel Solar Battery (150ah or 100ah) 1x 900VA Pure Sine Waver Inverter 1x Solar Panel 150W/200W 1x 30ah MPPT Charge Controller please do you think this setup is going to be okay for my needs? i think my computer setup takes around 12 -20W |
Re: Let's Go D.I.Y On Solar by CreepyBlackpool: 2:08pm On May 20 |
Hello everyone. Please I was given this quotation for a 3.5kva set up. I want to know if these are the appropriate equipments for the setup. 2 x 220 ah tashatubularbattery 4 x 400 watts tashaenergy panel 1 x 60 amps tashaenergy solarchargecontroller 6mm solardc cablepermetre Battery rack Trunking pipe, aluminum rails, nails and accessories SPDs, breakers, changeover switch and AC cables 1 x 3.5 kva Viltransformerbased inverter Are the solar panels enough to fully charge the batteries in a day? Is a 3.5kva inverter okay for 2 220ah batteries abi it's too much? Would it be better to use a hybrid inverter? What would you add and what would you remove please |
Re: Let's Go D.I.Y On Solar by bankoleabiodun3: 2:49pm On May 24 |
CreepyBlackpool: The panel will be enough. Yes hybrid inverter will be better |
Re: Let's Go D.I.Y On Solar by bankoleabiodun3: 2:51pm On May 24 |
Increase the panel. 300W JMonster18: |
