Guy Installs 3KW of Solar in 11 Minutes

I install 3KW of solar panels on a DIY solar rack mount. These panels are used but still have plenty of life lift in them. First I use 4x4's sunk in the ground to make the base of the rack. Next I use 2x6's as the cross section atached to the 4x4's. Once this is done I make brackets from all thread and aluminum bar. These connect unistrut channel to the 2x6's. the solar panels have a spacing of 39". To get the panels on the unistrut I use bolts washers and nuts. My system needs the panels in series. To do this I simply take the negative of the first panel and insert it into the positive of the next panel.

Love the simple array. Based off experience with mine, you really need a center support for the unistrut. Even with a nice pitch on them they’ll sag in the middle. Having 3 headers would be the best bet.

[@LandtoHouse]

My very first array has 3 headers. Its rock solid. Any place with wind i fully suggest that way. Here we don't have much snow or wind. So far in 3 months the solar has done well with this setup.

[@GavinStoneDIY]

@@LandtoHouse good stuff. Keep up the good content. I really enjoy it.

[@land2cabin]

We have solar also and want to put up another set of panels. Thanks for sharing your setup. We have to set up a winter set of panels. Previous owner did not do set up the panels for best for all seasons. I like how you calculated that into the setup.

[@hayderalsalman7984]

Nice we wait connecting it with system

[@StakrCZ]

When connecting the panels, it is good to keep them covered and use dielectric gloves. 400V= is no fun and it can kill you.

[@wadebrewer7212]

Its more about the current, but eitherway it isnt the greatest. Have you ever been lit up by a spark plug coil on a car? 50k volts. Hurts like hell but won't kill you.

[@StakrCZ]

​@@wadebrewer7212 you need over 100mA and it won't be a problem with this solar array

[@wadebrewer7212]

@@StakrCZ ever been zapped by 120v from something grounding out or bare wire?

[@StakrCZ]

@@wadebrewer7212 yes i got zapped by 230V (i'm from Europe) and from 6kV (by charged line transformer and line capacitor) I luckly survive, but 2 my co workers was get kill by 230V from 100VA transformer. I´m electrician in heavy industry.

It is always about the amperes!

Nice job Seth !

[@LandtoHouse]

Thank you. This install was smooth.

[@huwzebediahthomas9193]

Excellent home tech education 👍

[@LandtoHouse]

Thank you. This is going to be much appreciated on cloudy days.

[@zanderboy]

i foudn your channel just a while ago and its so fascinating. i view in awe of all your space and sunshine ( live in northern england ). great content, very informative and youre great infront of a camera. love it. keep up the great work

[@LandtoHouse]

Thank you for watching. I have almost 10 acres here. The sun shines most of the year. not as much as when I lived in New Mexico. sunny all the time.

[@jimginnyohio]

Looks good Seth!

[@LandtoHouse]

Thank you. I am about to turn this additional 3kw on tomorrow to see how well it performs on a cloudy day.

[@J3llyBean423]

AVP sweet / I'll keep checking you out /

[@radoslavtomov9121]

Considering that these panels are there to stay for the next 25-30 years I see no reason to use wood. I would do concrete footings and zinc coated metal for the structure. Do it right and do it once.

[@trumpingtonfanhurst694]

Good stuff, nice work!

[@LandtoHouse]

Thank you. This setup has worked well!

[@shadowhawk1st]

Do the panels have to be grounded? How would you do that with a wood mount? I've never seen you mention grounding your system. Or does it NEED grounding anywhere?

[@LandtoHouse]

In order to ground the panels I have installed an SPD or serge protection device inside the house at a breaker. This has an earthground and a 600 V clamp.

[@shadowhawk1st]

@@LandtoHouse Ah ok. Thank you

[@michellesmith77777]

Do you by chance have a link for those solar panels?

[@RowanHawkins]

So it obviously took longer than 11 minutes how long did it actually take from lugging the lumber to just before digging the trench?

[@LandtoHouse]

When I build and film at the same time it takes forever. This was 4 days worth of work. I should think you could install this in 1 full day if you were focused.

[@BobBob-il2ku]

Not worth it to make the rack adjustable for winter/summer?

[@LandtoHouse]

It would take a lot if effort to make this many panels adjustable. With 6kw i have all I need to keep a 15kwh battery going.

[@AHMEDGAIUSROME]

GG Seth !

[@LandtoHouse]

Thank you.

[@JR-xw5dk]

Thanks for sharing. Where did you find the lowest place to get allthread?

[@LandtoHouse]

Turns out Lowes was the best around at $34 each.

Maybe you can use Midjourney or Dall-e to generate yourself a new logo? Keep up the good work!

Do you worry about hail?

[@LandtoHouse]

I have lived in this area for 28 years and only seen hail 3 times. 3-4mm so not too bad.

[@imacmacnerd]

you don't need concrete for the poles

[@LandtoHouse]

It's worth putting a little gravel in the bottom to help drain water. But those Poles should last for 20 plus years without concrete

[@energyconsultantsgroupllc7007]

Lol, oh boy our worst nightmare in our industry, diy

[@LandtoHouse]

I should think 99% of solar folks are not diy. Plenty of clients for you :)

[@elizabethmcgovern9731]

Nothing new as thousands of panels are mounted and connected thank you.

[@LandtoHouse]

This additional 3kw should make a big difference on cloudy days.
