    nice project but why you don't put a 100w LED instead of strip LED is was more efficent because that Le d 100w run on 30v and drau about 3 ah and whith a step-up is was good this just my opinion i m not a big electric inginer i learn everything my self

    @GreatScott Why did you run the conduit up to the junction boxes and leave a gap? Why not run them into the junction boxes for full protection?

    Eh, this is quite a nice video about a small solar system. Too bad it just reminds me of the fact that I'll probably never be able to build something like this, because the dirty scumbag utility companies would never allow anything like this near their systems, not even an independent parallel run.....

  • Jean-Luc Coulon

    The solar panel would have a better efficiency if slanted (about 40 to 45° in Western Europe) and with a South orientation.
    The difference with an horizontal panel is really huge.

  • Bitelaserkhalif 555

    the only problem is the panel

    Would recommend using same wire size from solar panel to controlled for the controller to battery. Then biggest cable you can add from battery to inverter.

    free advice.

    I've worked with an electrician before. He said those orange and clear adapters on the inside of wiring kits start fires. Maybe you should remove them.

    If you angle your solar panel to the angle = to your location's latitude degree, that will be best efficiency angle for non-rotating solar panel.

    Hey Scott, Is it safe to use Modified Sine Wave Inverter on LED TV's, LED Bulbs, Fans? Everytime i plug my TV on my MSW Inverter, it produce little noise at the back of the TV. Btw, I only use my Inverter for 2-3hrs power outages.

    Hey Scott. Watching your videos I came across some ideas. Would a combo of a small 5v Solar panel + 5.5v 4F Supercap be enough to power an 5v or 3.3v Microcontroller (via buck/boost converter) over a long period? Could I also power a small 5v Servo Motor with that?

    Never ever mount a solar panel flat on the roof. Rain water and dust will not run of the panel. Even a 1 or 2 degree angle would be better than this.
    This also helps with the heat.

    Oh, and that bitumen won't hold it, as the frame of the solar panel expands and contracts every day.

  • John Ridley

    Up through the battery and charge controller it's not bad, but that wiring up around the LED strips, and just having the strips hanging there with no protection, is incredibly sketchy. I wouldn't allow that in my house or garage.

  • J Bishop
    J Bishop 8 days ago

    You really need to elevate that solar panel off the roof. Running it with no ventilation will make it exceptionally hot between panel and roof. Aside from a potential fire hazard, it will not generate as much power, as PV panels are more efficient at lower temperatures.

    Is is to do with coupling b/w the two as in would the AC induce an emf superimposed onto the DC wires?
