Re: Solar Energy, A Complement To FTA by easyyoke: 7:03am On Feb 10 |
Hello guys, I bought some generic 300W panel from a Solar shop. 2pcs. It was during raining season so sun wasn't really out that period. I noticed on my 40A HQST MPPT charge controller, the panel wasnt giving me more than 80W out of the stated 300w. (The MPPT charge controller shows you how many volt and Amps that is coming in from the solar panel). So I thought maybe it is because we were in raining season that period. Fast forward to January with full sun, I was getting 105w max per panel to give 210w out of the supposed 600W I am supposed to get. So I concluded I have bought fake panels. Then I decided, this time around I will buy original Jinko 550w from an authorized dealer. So I went straight to Foauni store(one of the authorized dealers in Nigeria). On getting home, I noticed I was only 275w out of the stated 550w too. Foauni does not sell fake products so I know I did not buy fake this time around. So I was wondering, is this the normal way solar panels work. Delivering just 50% of their rated wattage even in full bright sun. And even when my battery is very low this is still what I get. I know most times, when batteries are almost full, your MPPT enters float mode and reduces the power coming in from your panels but even at low battery percentage, I am still not getting more than 50% of the rated wattage of the Jinko 550w panel in full bright sunlight. My MPPT controller tracks the wattage all day and tells you at the end of the day the highest wattage the panel supplied and the highest I got on the 550w panel is 280W. And my controller does not have any current limiting function. Is this how solar panels work in Nigeria because most solar panel reviews in the US that I watch on Youtube, those panels produce atleast 80% of their rated capacity. |

There are so many things that affects Solar yield.... orientation, quality of materials, distance etc... I want to point out to you that we are in a dusty weather right now, so your generation might not be out of place as most of us are battling with poor yields due to the weather.... easyyoke: 2 Likes |

kristien4: What brand is your 580w panel and where did you get them please. You are getting about 80% yield and that is a very good yield. Your panels are original panels. I am getting just about half of my own rated wattage. What brand is your panel please and where did you get them? |

oloet: My Jinko panel is clean. It is brand new. So no dust on it yet. Just 3days old and I have been taking the reading over the course of three days. Good shinning sunlight. Yet the max I am getting is 270w out of the Jinko 550W |

easyyoke:what is the orientation of ur panels? Cable distance and type of cc |
Re: Solar Energy, A Complement To FTA by TechGeek777: 10:32am On Feb 10 |
easyyoke: You didn't state the configuration, also is it 24v or 48v? Inverter model and CC info is required |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 10:34am On Feb 10 |

That's nice. I really like the mppt CC built in the inverter It shows the wattage and amps the solar is charging at and even shows that of AC input together. Most inverter out there don't give those details. Also i noticed it has a fast charging speed for AC. Drgreatone: |
Re: Solar Energy, A Complement To FTA by oloet: 11:50am On Feb 10 |
easyyoke:As I have said, I don't think you have a problem for now, how are the panels connected, are they properly oriented, what charge controller are you using? |

brightk: I dont really have much idea about orientation. I have not mounted it on my roof yet. I just placed it outside for now. I want to add one more 550w to it before I put it on the roof. The wire length from the panel to my MPPT charge controller is 10yards. I am using a 6mm pure copper wire. The panel current is rated for 13A under loads. To troubleshoot if it was my wire that was the problem, I actually took both my controller and my battery close to the panel and ran the original panel wire straight from the panel to the controller and I was still getting 275, 280W max at peak sunlight. So I dont think it is my wire. It is a single 550w Jinko Panel bought directly from Foauni stores. Here is the picture of where I placed it. There is no shading at all. Ignore those other two panels. Those were the first 300w panels I bought. Those ones too are giving me 100W max per panel. So I have been wondering what is the problem. Lets assume those 300w are fake panels, this Jinko 550w is definitely original as Foauni store does not sell fake things.

TechGeek777: My system is a 12v system. I have a 200ah LIFEPO4 battery. A 40A HQST MPPT charge controller. I dont think inverter model matters here as I am not drawing any load from the battery while charging. Just purely charging the 200ah battery and I am only getting 275, 280wmax out of the rated 550w Jinko panel in bright sunlight |
Re: Solar Energy, A Complement To FTA by easyyoke: 12:47pm On Feb 10 |
oloet: It is a single 550w panel. I dont really know much about orientation. I just placed the panel outside. I am waiting to get one more before putting it on the roof. My controller is a 40A HQST MPPT Charge controller. Can you please shed some light on the orientation. Maybe that could be one of my issues |
Re: Solar Energy, A Complement To FTA by Penuelseun(m): 1:04pm On Feb 10 |
easyyoke:I would suggest you get another mppt controller 1 Like |
Re: Solar Energy, A Complement To FTA by easyyoke: 1:08pm On Feb 10 |
Penuelseun: Wawu. Not it is not my controller. My Charge controller. Is a quality controller made by Renogy in the US so it is a quality and expensive product ke. This cannot even be right. I have a clamp meter and I have measured the DC Amp directly from the panel’s wire as well as the Volt. It is giving me exactly what the MPPT controller is giving with just a little loss. So it is not my controller |

JoeSef0: Hmmm, this is not efficient, 300watts panel is connected to PWM CC on a 12V system. |
Re: Solar Energy, A Complement To FTA by Drgreatone: 1:21pm On Feb 10 |
JoeSef0:Running my top loader washing machine on it as i type. Advantage of the hybrid is u can oversize ur panels such that it powers ur load and still charge the battery which u sort of lose wit this pwm charger. I was goin to ask, whats the max panel input of ur pwm controller used? Looking like u connected ur 900watt panel to it directly? |
Re: Solar Energy, A Complement To FTA by Drgreatone: 1:24pm On Feb 10 |
easyyoke:Whats the specs in terms of maximum panel voltage, max panel input etc? |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 1:27pm On Feb 10 |
easyyoke: If a Jinko already produced 275W which is 50% of its capacity and your 300w were doing 100w which is 33%... it means your the Jinko already performed as Top Tier Panel. Your Charge controller is doing a bad job... Change it to another one.. Also note the Current Weather is very bad!! |
Re: Solar Energy, A Complement To FTA by AshipaEk0: 1:33pm On Feb 10 |
easyyoke: You won't get 50% output from those panels this period. Everyone is reporting much degraded output. Used to get nameplate, now max out at 45% ish Run these checks in 3 - 4 weeks when the bloody Harmattan is done 1 Like |
Re: Solar Energy, A Complement To FTA by dollarnaira: 1:44pm On Feb 10 |
easyyoke: Am sorry bro But I laughed out loud upon the above. Not dust on the panels o. But huge dust in the air above affecting everyone Jinko or no Jinko. Wait for the first or 2nd rain to wash the said Harmattan dust in the atmosphere off. By then, sun rays will fully hit your pv wella. Dust don chop better part of the sun comot. So bro, the sun you are feeling now is big fake. Leave your set up till March/April and check again. Cheers. 2 Likes |
Re: Solar Energy, A Complement To FTA by oloet: 1:44pm On Feb 10 |
easyyoke: Please wait a little while for the weather to clear ,a properly oriented panel will face the sun directly 80% of the time...my opinion though 🫣 1 Like |

easyyoke: Your roof slant too much? I believe Max 25 Deg is allowed for optimal performance of the panel. Btw, no be too much money dey make pv perform oh. |
Re: Solar Energy, A Complement To FTA by Obnoxious2001(m): 2:21pm On Feb 10 |
easyyoke: You have no problem. The panel is trying your concern should be to increase your cc. The 40A can only fend for 550w × 2. That if you don't have plans to install the 300w panels |
Re: Solar Energy, A Complement To FTA by easyyoke: 3:04pm On Feb 10 |
AshipaEk0: Thank you. This seem like a very logical answer. I will wait till after the harmattan is done. Thank youuuu |
