JohnKester: wow, am more encouraged now. it now remains who would be the first to install this in a fresh build, it would be a radical departure from the usual, and many nay sayers would be on overdrive to discourage one. i think i wud put it on my sumo tank stand, or many above the sumo tanks, to prevent shading who has done a new build and incorporated this?, come gimme tips |

Reprobate:It was with Richmon74 but it had to do with stock pictures of solar products e.g panels, batteries etc and not passing off someone's installations as your own. There is a big difference as that is deceptive marketing and for a consumer a total misrepresentation. 3 Likes |

What is depth of discharge (DOD)? DOD, also known as “Depth of Discharge” is used to describe how deeply the battery is discharged or should be discharged. If we say a battery is 100% fully charged, it means the DOD of this battery is 0%. When a battery have delivered 30% of its energy and having 70% energy left, this means that the battery is at 30% DOD. A battery that is totally used is at 100% DOD. to read the full details on this, click the link below https:///swn8JT |

earthrealm: Mine is actually on a new building and central hot water supply system was already provided for in the piping design. I did not have much problem with the installation because the building has a concrete flat roof and I just installed it on the roof. It can be installed anywhere you have direct unhindered sunlight to it even if it is not close to the tank stand. All that is required is to pipe inlet supply to it and pipe outlet to the house and the rest is for it to work. It can be on its own tank stand, which however, should be below the level of the water supply tank stand, so that gravity can still supply water to the water heater. Note that having it above your tank stand would mean that you will require a pump to send water to it, or pump directly from the sumo to it. However, this may not function well as the tank may run dry, except of course you automate the pumping which may deplete your batteries if it happens frequently at night when there is no sunlight. The design of the solar water heater is such that once water is going into the house from the outlet, the inlet will automatically open to let in water to fill up the tank. You will achieve better result if water supply to it comes from your overhead tank that will not require power. Cheers 5 Likes |

My good people, anyone willing to share their PV generation in the last few weeks since the rains started? I am getting just about 30% of installed capacity at peak which gives me some concern. Most times, a miserly 10-15%... and it's not raining! Thanks o! |

battleaxe: How do you determine peak time, mid day or sun highest intensity for the day? |
Re: Solar Energy, A Complement To FTA by Chuckdee(m): 9:13am On Jul 31, 2017 |
battleaxe: If you say 10-15% when its not raining and with good sunshine, i think its poor. A visual inspection of your setup is a good place to start off trouble-shooting from. I have been pleasantly surprised getting some very handsome harvest all this season. I think the cool weather and dust-free panels are helping. I have seen 4,491W out of my 4,500W total capacity at peak sun intensity (11-1pm ish) 1 Like

dapsyra:Afternoon bro, How do you manage your heavy loads during bad weather? Do you play power police? I have also implemented the 8am to 4pm strategy on my Heavy Loads DB, but the challenge is during bad weather when my water pump kicks in, it pulls the battery voltage dangerously low. I'm looking for an energy management system that can energize certain heavy loads at different solar production levels. |
Re: Solar Energy, A Complement To FTA by dapsyra(m): 9:11pm On Jul 31, 2017 |
Barezzi: My charge controller has two auxiliary ports which can be configured to switch a relay on/off at preset battery voltages. I configured the Aux1 to switch on the relay powering the heavy loads DB when battery voltage hits 57.8V and switch off when battery voltage drops to 52.6V. This way, the opportunistic loads cannot drain my batteries even in bad weather. A programmable timer fires another relay at 4pm and switch the heavy loads DB to PHCN. It also switch the DB back to the inverter at 8am. 5 Likes |

battleaxe: What direction are your panels facing and what is the degree of inclination of the panels? The above questions are very important and I came to appreciate the importance about 2 months ago. My panels are installed, facing south, which is not a problem. That is actually the appropriate direction. The angle or degree of inclination should be between 6 and 10 degrees. The difference in performance of properly inclined panels and those not so inclined is much more significant than I appreciated before now. I observed not long ago that the direction from which sun rises had changed significantly to the extent that my panels installed at about 30 - 45 degrees inclination were almost backing the rays as the sun is rising and would remain almost like that for the day. It was then I actually noticed that my angles were wrong. So I dropped the panels to 6 degrees inclination and guess what? My 5.3kw pv arrays which before then would take till about 5.00 to 6.00 pm to fully charge my batteries, can now complete the charge at about between 2 and 3 pm! A difference of about 3 hours! There is a significant improvement in the yield. My batteries now float almost everyday, even when it rains sometime in the day. The beauty of 6 degrees is that whichever direction the sun takes, the panels have complete and direct supply as long as there are no shades! One more thing, You need to test your panels to ensure that they are all functioning. Also from experience, my second pv array of 2.25kw which is supposed to yield at least 3/4 or 2/3 of the yield of the first pv array of 3.06kw, was actually yielding less than half of the the first array. So I had to troubleshoot and in the process discovered that one of the panels in one string was not functioning. Fortunately, it could be repaired, which was done and the thenceforth the panels started performing to expectation! The effect of such a problem is that the entire string (in my own case made up of 3 panels) would not contribute any yield to the production of the array. So I had two strings functioning in a 3-string array. So you need to do an audit of the system to discover where the problem may be. Cheers 6 Likes |

dicksonadams: i had a similar experience like johnkester with my newly installed solar panels. after installation, i noticed one array was producing roughly half the power output of the second array and so i set out to troubleshoot. in the process i climbed to the roof only to discover that the mc4 connectors of two array strings were not properly closed. what that meant was that out of twelve panels, only six were producing thereby explaining why the output was half. i quickly reconnected them properly, climbed down from the roof, switched on the array breakers and voila! more amps than i could imagine started pumping into my cc. it was really a remarkable experience for me. 2 Likes |

dicksonadams: Some installers can really be frustrating & that is why I turned diy. A 450w should really yield more than 100w except u've paralleled ur installation if they're 150w panels or lower. Also, if u mix panels of different watt, CC tends to pick parameters of the lowest panel and limit production activities to protect the lowest panel thereby harvesting in that region irrespective of cloudy sky. I stand on all what previous gurus have mentioned because I had similar experience too. I the course of my diy experiments, I had four 150w panels installed in series of four instead of 2x2 or just 3 series. And on the 3rd day, it was really sunny, guess what? I heard a loud BANG! from rooftop. I never bothered to check until my harvest dropped to a shocking level. I had to audit the whole setup and discovered the last unfused panel in the series got cracked! Of course after disabling the culprit, my harvest returned. It is very true what johnkester said. The sun has moved to another limit due to earth revolution. And during an upgrade I reset my inclination approximately and got higher yields dispite the rains. By the way, I hold constant that ur cables/connectors, breakers etc are proper. If so, then tell ur location and let gurus close by do audit for you. Cheers |
