SolnergyPower: ![]() ![]() ![]() Thank you for your prompt supplies over the weekend. It seems You have really improved your poly panels. Their production/performance @ 3x2 out shines my previous mono of 3x2. Am really impressed and thoroughly satisfied with your after sales services too. I will not underrate poly panels again. Thank you. |

TSHIRT2: With the current technology used in panel production, There is no difference.. poly tend to perform better nowadays.. The only advantage mono has is the wattage per surface area.. But it's an advantage on poly more surface area seems to be more wattage.. 3 Likes |
Re: Solar Energy, A Complement To FTA by babaegun(m): 7:33am On Aug 31, 2017 |
Dam5reey: Great to know that Poly Panels are equally good now. So what about the size of poly panels as compared to mono panels? if it is still slightly bigger, what matters is where you intend to install it. If you have more space, no issue but with limited space comes the "challenge". But am sure the technology will surely merge one day, improve on current production and get smaller.. |
Re: Solar Energy, A Complement To FTA by bodeface: 8:18am On Aug 31, 2017 |
There is currently a very thin gap between the Poly and Mono PV panels nowadays, gone are the days when the mono used to be the king, with more research and improvement in production process of the Poly Panels, the gap between the two - efficiency of conversion which boils down to the area required to generate the same energy (e.g. 300W) has been closed up and very soon, Poly will become the king when the gap is fully closed and the wining advantage for the Poly will be the cheaper production cost compared to Mono. For an example, lets me use the SUNTECH PV Panels to show you what I am talking about, Mono-crystalline 325W and Poly-crystalline 345W, these two panels has same dimension, the same wattage, their difference currently is just that the efficiency of conversion of Mono-crystalline is 17.7% while the poly-crystalline is 16.7% and if you do the calculation just 1% efficient than the Poly-crystalline, apart from the efficiency everything is same. Please see the links (copy it as a whole into your browser) http://shangde.fanyacdn.com/imglibs/files/iec_stp325_vfw(mc4_325_320_315).pdf http://shangde.fanyacdn.com/imglibs/files/stp345s_vfw(mc4_345_340_335).pdf Currently, I use SUNTECH Poly-crystalline PV Panel and the performance has been extremely satisfactory, my advice though is know what you are buying, in Nigeria most vendor over rate the panel they are selling for you, 250W are re-branded as 300W and so on, so be careful, but there is little or no difference in Mono and Poly PV Panels performance. 4 Likes |

bodeface: Wow !! Just confirmed it. And the dimensions, completely the same Ahhggghhh! That nailed it. The price will soon be the determining factor in choosing a PV and Poly panels will surely carry the day. But am sure the Mono Panels researchers will not just fold their arms. Well, whatever the case, it is the consumers (us) that will benefit at the end of the day. Renewable Energy is the way to go... 1 Like |

Mr JUO man of the year, God bless you brother, keep up the good work. As for the controller war, are we saying the classic beats the Tristar,cos according to oga George's review Tristar lost the fight. Can we rank controllers according to brand. Of course we ll need more reviews, over to the house pls. Who ll giv us review on the schineider controller. |

Hello house, I am looking for inverter brand recommendations based on people's usage experience - something below the price of the premium Magnums & Victrons & Schneiders but a solid performer regardless with professional repairs & maintenance presence in Nigeria. I currently have two 48v Mustpower type inverters 5kw & 3kw respectively alternating day and night duty via manual switchover but these are crazy power guzzlers with 230w & 130w idle consumption amongst other issues. I need something that can take a continuous 3kw to 4kw load without shaking and low idle consumption (below 100w) with ability to withstand my solar charge controller's charge/equalization voltage up to 62v. Suggestions/recommendations & sales pitches are welcome - u can PM me privately if need be... 1 Like |

@Dunka - This is the very advice I would have given as well were it not for my cash constraint. I also believe there must be a mid-range option that is excellent value for money and definitely someone in the house must be in the know ![]() With Victron & Magnum 4-5kw range selling for 800k plus - those are not friendly prices at all after I already invested in ~20kw worth of L16 batteries, 6.3kwpanels & MorningStar CC. I am looking for a value/mid-tier option - to use a car analogy, I want a Toyota Prado SUV which is a solid performer vs. A Mercedes or BMW or RangeRover SUV which are all excellent premium/luxury options.

Re: Solar Energy, A Complement To FTA by DUNKA(m): 7:59am On Sep 01, 2017 |

Re: Solar Energy, A Complement To FTA by Saipro(m): 11:38am On Sep 01, 2017 |
zeestone99: Pretty good controller. Sturdy. I have one. I will volunteer just three comments: 1. Pretty dependable but somehow tend to give issues shortly after expiration of warranty (typically 5 years). Customer service support is fair. 2. Performance-wise, it's just about another option out there. Nothing really outstanding asides coming in different flavours. 3. Pretty pricey. Not sure the cost justifies the performance. For roughly the same price, I'd rather you go for an Outback or preferably a Midnite. One would need a cost:benefit evaluation. By and large, if your array is 1kW or less, generic brands are okay (marginal difference in power conversion; longevity is a different matter). If 600W or less, you could save money by getting a PWM controller instead (Midnite brat is quite versatile but has DIP switches - a minus of sorts for me). |
Re: Solar Energy, A Complement To FTA by Saipro(m): 11:49am On Sep 01, 2017 |
DUNKA: The problem is the cost. Once again, cost:benefit evaluation comes into play. Nothing black or white here. It's true when you pay peanuts, you get monkeys. At the same time, one must be shrewd. I have two flavours of MustPower PowerStar inverters. Both 3kW (24V and 48V). Yes, they both have an idle consumption of about 100W (which curiously reduces as you load them). Both are remarkable performers and have taken everything I've thrown at them. Believe me, I've taken them to the limits and beyond. I did a little splurging on panels and batteries to compensate for the idle consumption difference (and still had money left over, had I gone with the option of a premium inverter). A win-win if you ask me. Sadly, I have no more than 2.5 years worth of experience. As the years tick by, I'll volunteer more info. 2 Likes |

DUNKA: I can second the Prag solution. I have a Prag 5 KW /6.5 KVA running for 4 years now without being switched off except Xmas in office Handels the LED lights ( 1 .5 KW) laser printers, Photocopiers and one AC without any issue. My earlier SUKAM used to make loud fan noise on the same load and I chose PRAG as the FAN comes on only when boost charging. The only model I know in market which is rated at 3 times rated surge power Also, Has a power saving mode so You can throw it in Power saving when not using to allow it to charge batteries when NEPA is available without depleting batteries But it is also climbed in price now that I checked on Konga 550 K https:///prag-48v-v-series-pure-sine-wave-inverter-2787585 |
Re: Solar Energy, A Complement To FTA by Saipro(m): 12:01pm On Sep 01, 2017 |
bodeface: Very true. In fact, those quoted percentages are lab things. Real life application and harvest lowers the difference further as neither is usually maxed during NOC. In my limited experience, there's no real difference (size or otherwise for the same panel ratings). Labels can be misleading though. Bear in mind, some manufacturers actually understate their yield (a weird paradox) in order to oust the competition with "equivalent" products. And my low-light yield is high is higher for my polys (once again, not to be mistaken for multicrsytalline panels). Undisputably though, mono has a longer lifespan. That has remained a fact. Yield deterioration with aging (let's call it diminishing returns) is also lower for mono. Result? Poly might start faster and better but mono will on the long run not only catch up (2 - 3 years down the line) but outlive and outshine poly. Literally. Or so my enthusiast friends have proven. |

I agree bro - with my MustPower 3kw I can use the microwave (1.5kw) and water dispenser hot water OR iron and dispenser hot water and 1hp AC simultaneously! - been doing so for two years now without issues. With the 5kw used mostly during the daytime I can run 2hp and 1hp AC & Washing Machine & other loads concurrently without issues. MustPower load carrying capacity is legendary for the price point - where they have failed me is the mains/charging interface - both became very finicky and unstable within one year of use and eventually I had 2 disconnect them both from the mains & go to strictly solar charging with an external telecomms charger as power supplement for cloudy days - a suboptimal workaround as you can imagine - to my chagrin, I changed boards for the 5kw and it still refused to charge with the mains - always sensing high voltage where there was none and tripping off due to 'overload'. I use a Prag 10kva servostab plus I have two Fluke multimeters amongst other power monitoring tools so I verified there was no high voltage coming through. Anyways, that's why I am in the market now for a new inverter with the ruggedness of the MustPowers but where the mains charging won't fail - I plan to dispose the 5kw and keep the 3kw as a backup and use only the new inverter for all my needs going forward - it should work perfectly provided the idle consumption is low enough - with this I can equalize my battery bank reliably on a regular basis with PHCN or Gen vs. chasing perfect sunny days to use my solar charge controller for equalization.

Re: Solar Energy, A Complement To FTA by DMerciful(m): 7:49pm On Sep 01, 2017 |
@ Dunka, if his reason for wanting to discard the mustpower inverter is high idle consumption, mind telling us the idle consumption of the premium brands you recommended? I use mustpower but i also have a small inverter i use for light loads(lights & electronics) that consumes about 10w idle power. I only use the mustpower during the day or when powering refrigerator n microwave/iron ![]() DUNKA: 1 Like |
