bx is for indoor use only.

[hermancando]

this dude is scarry  bad info

[reddawn5297]

Solar Panels are cool. I'm building one to have a back up generator. I'm thinking about putting money away so I can use the money to get off the grid.

[WDArizona]

For DC circuits, BLACK is ground & RED is positive. I might use the NM cable, labeling each end of it as carrying DC Voltage. With NM cable I would use BLACK as the ground & WHITE as positive. I would wind some RED electrical tape around each end of the NM cable's WHITE wire to indicate it is the POSITIVE wire of a cable carrying DC voltage.

The alternative would be to use CONDUIT, BLACK for ground, RED for Positive and a ground wire attached to the panel's frame to a good earth ground.

[TheElectricpablo]

Black is positive! White is negative! Wow! How many violations -_-

[mrtruthify]

@TheElectricpablo

In working with Direct Current [DC].. Black is your NEGATIVE, & or GROUND, while Red is your POSITIVE.. just as on your CARS 12 volt DC system [12VDC].

There is no white, typically.

Ball park fig, how long do solar pannels last

I am a master electrician and I was looking for advice for an upcoming project involving a photovolaic system, but this video is a total joke. The MC cable is not rated for exterior use (among other issues with his install method) Also everyone seems to be wrong about the ratings, no. 12 conductors are rated at 20 amp max, all conductors for line voltage systems (120/240 volt) are actually rated at 600 volts. Regardless, this is simply the wrong material for the project.

[solarpanels3]

The cable this guy is using is rated 110 volt max 15 AMPS

Does it tell you somethink ..............

[solarpanels3]

the only reason I would not use mc cable becouse its expensive and reistance (one string)

[solarpanels3]

This guy have maybe max 20 amps max from his panels @ max 40 volt.

People you dont know what you are babling about.Seal the conection with some silicon

ground the shield and you are OK.The only think that can kill you is loosing your balance. Mc cable are not for outside use becouse it is for 110 - 220 Volt.

40 Volt DC max 20 amp is perfect. 100 of times I been hit by 25000 volt from tv picture tube and I still living..

And learn about OHMS LAW,

[amberjacksolar]

Thank you very much for sharing this video. It was extremely informative.

[MrNightro]

690 in the NEC is topic specific to Solar Photovoltic systems & the section I mentioned in my earlier post describes the cables suiteable for use. SOOW is fine & can be used since it is both sun & wet locaction suited.

[WizzRacing]

You can look it up in the NFPA 70, Class1 Div 2 NEC. 501-4 suitable for wet locations and outdoor use. when used with a water tight connector or L5 plug on a NEMA 3R or 5R Junction box. this is allowed in California which is the most strict of all the states on NEC codes.

[WizzRacing]

Might try using SJO or SO cord, with a nema R rated cord cap and encloser. using MC cable out doors is asking to get killed. you can be liable for giving bad advise even on Youtube. try reading the NFPA code on NEC codes on electrical.

Just a thought

[MrNightro]

@WizzRacing You can't use junior sevice cable (SJ) for this, go for rubber cable rated for sun resistance as well as wet locations.

[WizzRacing]

@MrNightro Maybe I should have been more clear, SOOW is allowed for outdoor permant use, where the "W" means suitable for wet locations. under the 2008 NEC code. it does not violate the 400.4 since it is named in the table.

[MrNightro]

@WizzRacing That's better, I will have to check the update in the 2011 NEC but I am not due to get it until Monday. (I think it should still be the same though) For the 2008 NEC look at 690.31 (B), (C), (D).

[VooDooAssassin2]

hmm building code in my area requires white to be + black - and green to frame

[SmallWindTurbines]

Our Small Wind Turbine kits have both wind and solar as a hybrid energy kit. Solar never charges at night or on cloudy days. Wind power kits are a great way to reduce or eliminate your home energy bill.

[MrSolarenergy]

where can i order the clamps an tracks to mount my panels on the roof

[centralscrutinizer76]

wow dont do like this guy .Those connections arent going to last long out in the weather . I give it 2 months before the connections are green with corrosion and fail . You need to make good connections in a weatherproof box .

[stevegoff420]

while I admire your ingenuity, the same can not be said for you adherence to the NEC electrical code. That MC cable you're using is not suitable for outside location. Sealtight/Carflex NM is required.

[bergsteinlife]

@stevegoff420 i was wondering why he wasing that BC cable outside ?

This is the type of "self proclaimed" expert that will teach you enough to get in trouble and burn your house down.

There is no electrical inspector on earth that would pass this installation.

Before you take any pointers from the "self proclaimed experts", check with your "NABCEP Certified" experts and ask if the installation is going to fly.

[Klippencott]

jschez5258: I will be hooking up my roof panels in a couple of weeks. Can you make a video showing the proper way to do this?

[123kkambiz]

unfortunately anybody who has a camera , have become expert in their own field, specially people who work with solar installation, almost most of self proclamed expert in this field do not know much thing about the solar system and the regulation need to follow, even inspectors do not know the rules and regulation of NEC 690,

[blademon7]

Type UF (underground feed) rated for direct burial in ground and all outdoor locations, and waterproof connectors to box and panel, as well as splice/wire connectors APPROVED for D.C. might improve this setup. And don't fall off the roof.

[largohoss]

adds to cost of system and the insurance agencys would love to disqualify homeowners and disallow your claims.Duh perhaps after spending so much or any hard earned money one should invest in qualified installiation . Inspections and insurance may be requisite to authority having juristidction being notified and bank loans may be tied to this as well as rebates and tax credits/beware

[largohoss]

the flexible bx/mc cable is not rated or suited for outdoor wet or damp locations and the splices are not either/further the connections should have been made at the other end first for personal safety and equipment protection, oops,

[madjam002]

With my solar project, I got a small battery trickle charger for £10 of ebay, 12v car battery from scrapyard for £8 and 150watt inverter for £10 off ebay too. Wired it all up, and I got mains electricity!

[tomhop16]

hi there,

this is like to my set-up!

i got 3 trickle chargers linked them in parallel.

what is your panel 1w or 1.5?

[madjam002]

I have a 1.5w solar panel

[tomhop16]

cool,, take u a while to charge it up lol

[madjam002]

No it charges really quickly!

I thought it would be slow though

[tomhop16]

wow cool,

im looking to upgrade mine

[bergsteinlife]

guys dont use rx wire outside. use TEC wire

[SayNo2ClosedMinds]

As per previous comments, why not connect using a waterproof box. Also to cut down on dangerous voltages whilst installing why not cover the panels with black plastic bags, surely this would reduce the output considerably and the danger of shocks.

[tomhop16]

sorry to question you, im new to all this but surely if this is a 12v battery charging panel, the most voltage from the panel gonna be about 30vDC?

[63vetteguy]

Installing in the sun with no cover is not the best idea, cover the panels. Thhn is not a good wire, for DC, multi-strand wire you get less loss, better performance. dwdavis is right, voltages, after 20 yrs. seen "installers" end up shocked, falling off roofs, 1 electrocuted to death. So at least get some education before attempting an install on your own because your life depends on it. trying not to be negative, I did not ask if you had combiner boxes, disconnects, fuses, grounding.

[dwdavis]

This is a perfect example of why solar electricity should be installed by a knowledgeable electrician. Flying splices up on the roof with exposed wire nuts and no weather proof box? BX cable used outdoors? Are the wire nuts used even UL listed for DC voltage? On some grid tied systems, roof top voltages can approach 600 and are commonly above 400 volts. Those voltages can throw a 40K degree arc 4 inches. Don't burn down the building.

[raaveratilan1234]

i have a scientific project and i decided to do a small solar house. i will like to turn on a small light with solar light. if you can help me to do this and to connect the solar cells together i will thank you very much. the house is made of wood.

[hugarooster]

Thanks, keep up the good work. Very good video to get handle on basics. Love the detail you slowly explain.
