Installing racking system for solar panels on composite shingles roof.

[@johnlittle3410]

The first video i have seen with someone that understands what he is doing thank you

[@jkepps]

Excellent video! Thanks for the tips!

Could an electronic wall locating sensor tool be used to locate the location of rafters as well?

[@SolarEngineering]

Maybe commercial grade that can shoot signal deep. The cheap stud finders will do nothing.

[@StéphaneLaporte-o7u]

In order to finder rafters, Would a tool like this work ? BOSCH Wall and Floor Detection Scanner D-TECT 120 ; The Bosch D-Tect 120 Wall and Floor Detection Scanner features Spot Detection technology to accurately detect objects behind walls, floors, and panels.

Thank you for this very detailed video. What design software tool are you using to generate the solar panel layout that you showed in the start of the this video?

[@SolarEngineering]

I'm designing a system in opensolar.com, and then ordering permit packages from the tech design company.

[@rajs8472]

Thank you. I’m in the process of planning for installation. I bought my solar panels already. Instruction videos like yours are really helpful and give us the confidence to DIY. Thanks again.

@@rajs8472 good luck with the installation!

[@peterxyz3541]

What type of sealant or caulking is that? Is it an adhesive or is it a waterproofing?

[@SolarEngineering]

Chemlink M1, waterproofing

Hmm, I wonder if it could be a good idea to drill from underside/inside attic when you install on this kind of roof. Then you dont have to miss any rafters and less holes. But usually in norway you never see different distance between them. It's by code a set difference according to the angle of roof to secure that it has the strenght to hold snow in winter. I have same type where I live, but sadly have isolated and paneled on the inside of the roof. There is no regular attic but a loft.

[@SolarEngineering]

IMO missing rafters is not a big deal with this kind of mount. Drilling from the attic will increase installation time a lot, because marking panels layout, and straight lines across all rafters could be a real challenge.

[@AJourneyOfYourSoul]

These houses with a low pitch roof have very little room in the attic. It would be too difficult and time consuming to do the layout and drilling in the attic. The latest mounts don’t even require you to mount to the rafters at all and just to the deck. Some even mount directly to the panels and have no rails at all.

Awesome video, great explanation, could you also explain how to do grounding? And where ground polls should be located. Btw i like the rus-en conversion with your buddy.

[@SolarEngineering]

grounding wire will land in main electrical panel, you can find more details here: kzbin.info/www/bejne/nofdcn6Aq92FoK8 and thanks for the feedback

[@sorrelwe]

Dude come to TN to install panels on my roof!

[@lamartravis1]

Can you provide a link for the low profile roof jack??

[@jimginnyohio]

Great tips! Thank you!

[@HenrikBentel]

Great content! I notice in videos you always use mounts with flashing. Any opinions on Ironridges flashless mounts (Halo Ultragrip). Would be great with a video comparing the different mounts(fladhvue, flashfoot, halo ultragrip) :)

[@peterxyz3541]

Thanks, useful.

[@kesleicarvalho4062]

Uau, os telhados aqui do Brasil são bem diferentes e bem mais desafiadores pra instalar painéis solares. Os telhados aí são bem melhores pra nós que trabalhamos no setor.

[@samfish6938]

someone else measures 48 on all roof then uses hammer he only drills once and uses small flashing

[@tvguide4khv]

Why your teammate speaks in English but you reply in Ru?

[@SolarEngineering]

he understands Russian but finds it difficult to speak it

[@tvguide4khv]

​@@SolarEngineering sounds so strange ) his speech so clean )) say hi to his ru grandma ))))

Geez.. So many better ways to find the solid wood

[@SolarEngineering]

please let me know a few
