    Finally, the start of my 25kw Ground Mount grid-tie system

    How would I go about calculating the peak productions on a multi-oriented system? I currently have 45kw facing directly south, however I am looking at adding on to a garage that will have a fairly large E-W facing roof. I'm still in the design and thought phase of the garage, but I want to take...

    Finally, the start of my 25kw Ground Mount grid-tie system

    Another day without issues. I'm loving the data that I've logged within HA. I'm thinking of building an addition on our detached garage that will have a roofline at about 20ft high. I was able to use projections from suncalc.org and then use data from last year to see at what point it would...

    Today it worked as expected, so hopefully just a weird series of things that tripped that error.

    I was wrong. I just logged in and it shows warranty to OCT 2032, so 10yrs from install/registration. I'll probably know of it becomes an issue by then. Ha.

    At this point, that is my thought. Fingers crossed, otherwise expensive and a PIA. I did register them, but can't recall what the supposed warranty is. Warranties are always a pia and pretty much are granted the way you would expect. Edit: I think a 2yr warranty is the standard warranty...

    Finally, the start of my 25kw Ground Mount grid-tie system

    Just happened to look at my solar prod in grafana today and noticed inverter 2 wasn't producing. It received an error 427, which has basically no description in the troubleshooting information. Is all I can find is hardware fault/error. It did this on startup this morning so it was never...

    @wattmatters Great summary! Way better than mine. ha. We are doing well. Just a bunch of logging going on in the area and demo work. A home here and there being rebuilt already. I've been occupied with all of that and then I've also been working largely on a heat reclamation system I built for...

    Finally, the start of my 25kw Ground Mount grid-tie system

    I'll get some numbers up soon for anyone curious, but 2023 yielded 61.98MWh with the projected range of 57-63 from pvwatts at the time a made that print out. I got the highest voltage at the inverters I have seen to date today. It is -10F outside right now. They hit 800vDC give or take a volt...

    It is crazy and awful. Thank you for sharing.

    Finally, the start of my 25kw Ground Mount grid-tie system

    We are ok now. It's more or less just processing everything. It doesn't quite feel real even though you see it with your eyes. We look across the lake where the vast majority of the homes were lost and it is just brick chimnies and foundations. It looks like a warzone.

    Yeah, it was pretty crazy. We could not have been any closer to the fire without burning ourselves. I'll have the reported numbers for august, I just haven't had the time or energy. I'm a bit drained physically and emotionally. Fingers crossed you guys do well.

    Finally, the start of my 25kw Ground Mount grid-tie system

    It's been a crazy last couple weeks. I almost lost my home and the solar field from wildfire. So many of the homes on our lake, friends and family, were lost. The fire burned right up to my property and stopped. I attribute this to three things, the adjoining property just mowed their...

    Finally, the start of my 25kw Ground Mount grid-tie system

    @wattmatters I like the setup! looks great. It looks like a good solar day too on that day. We get a season of pollen here too. We don't get much rain in the summer here. It usually rains a couple times. I'm pretty much just counting on that to clean the panels. It's just not worth the time...

    Finally, the start of my 25kw Ground Mount grid-tie system

    I think I came across pylon when I was going my property, but I didnt 'have the premium sub. I get hit with some tree shading in the winter on the last 1/3 of the day or so. Thus far I'm happy. It's running well. I haven't cleaned the panels once nor had to do anything else. This fall I will...

    Wow. I definitely missed some posts. great charts and info! July numbers are in: Projected: 7.86MWh Actual: 8.75MWh Over produced by: 11.3% I adjusted some things on PVwatts to hopefully give an even more accurate representation of production through the year. Once I have a full year of data...

    Alrighty, another monthly performance update on the system. Projected: 6.37MWh Produced: 7.87MWh Overproduced by 23% Best day in May about 310kWh.

    Sail boat mounted panels 4-6 roughly 500w - suggestions?

    I have since realized that would not be the way. lol. I have changed the thread title. The thought process of having each panel individually "controlled" vs putting them in series seems like the most ideal though since if he has a panel go down or get damaged then it wouldn't only affect that...

    April numbers (wrong, see below): Projected: 6.3x (don't have the sheet in front of me) Actual: 6.15 Missed by about 150-200kwh. IMO the month was a bit cloudy. I never had a single "perfect" solar day. I had one that was kinda close. For some reason there were always "whispy" clouds in the sky...

    Sail boat mounted panels 4-6 roughly 500w - suggestions?

    I have a friend that is going to be replacing the really old panels on his sailboat and he wants to go with a DC install size of around 2kw. I'm thinking that micro inverters would be best due to shading from the sails and not necessarily being able to control this aspect. It would also add a...

    Does solar panel clamps affect snow removal?

    @rhino I have my panels mounted in portrait (2 high) on a ground mount system. I have found that the clips don't keep the snow up there. The snow still hangs at the base of the panels from the frame. I only went out to clear snow off them one time to try out the removal squeegee and being in...

    If I put up a shop I'd like to put standing seem metal roof on it and put solar on it!

    hit about 5.7MW this month out of the projected 5.05MW. I think next month's projection is about 6MW.

    About as perfect as it can be and still made just about exactly as the snow covered ground day on March 7th. March 23, 288kWh I'm taking a look at your link now.

    @pilotdrh how do you like the philippines? Were in the the states prior to moving there?

    Finally, the start of my 25kw Ground Mount grid-tie system

    Absolutely. I'm certainly getting bifacial gain now even with the snow gone, but it's more or less giving some sort of comparison between a white ground and natural ground and my light colored rock below/around the arrays.

    Finally, the start of my 25kw Ground Mount grid-tie system

    For anyone curious. The snow is gone now. This is almost a perfect day and much more perfect than my previous "best day" since going live in Oct. The first day, March 7th, the ground was covered in snow. Today, March 17th, there is no snow on the ground. Even though the power production through...

    I'll do ya one better! Edit: @pilotdrh has some awesome panels. If I were doing it again I would have definitely seen if I could make the ones he got work.

    Finally, the start of my 25kw Ground Mount grid-tie system

    I've definitely noticed that. With the current sun elevation the max continous I will see is roughly 14kw/inverter. On days where clouds are sorta in an out or passing by I'll get the inverters to max. I'm excited to see the data throughout the whole year.
