    Hey Bibs, what, “work,” are you going to do! I’ve had a 1.4 kw array for 14 years, it’s never needed any work. I brush snow off of them, and trim the trees south of the array every few years. Other than that they don’t need anything. If you suspect you have a bad panel, and you want to check the Voc (volts open circuit) or IMAX (max forward current) on individual panels, simply turn off the array either at the charge controller or array combiner box, and open the junction box on the back of each panel, one at a time. Then with the proper meter you can check each panel to see if your voltages and current are close to the ratings on the panel data plate. If you’re not sure what meter you need, call tech support for the manufacturers and ask them for advice on testing your particular panels.

    You can keep the array all wired together, no need to disconnect individual panels, with the array shut off and one junction box open the maximum voltage you’ll be subjected to is the one panel you’re measuring, usually less than 38 volts. If you find a bad one, there’s generally nothing you can do to repair it, short of checking the connections or replacing the entire panel, there isn’t any other work to be done in the field.

    If your working on the array mounts or other external hardware, don’t worry about the wiring, it’s no more dangerous than a 100 foot extension cord in the yard. Take care Bibs, Rudydoo.

    treat as if it is live wear lv gloves if your worried. tag off all isolators,know the open circuit voltage of the cell and the array you are working on.

    Depends on the solar panel.

    It it is installed, it will depend how it is installed... and how much power is involved.

    If it is sitting in storage waiting to be used... that would not be unsafe.

    I have a small "emergency solar panel" that can charge cell phones, portable radios and rechargeable flashlights. It does not put out enough power to be dangerous if I needed to "work on it".

    I have a 160 watt flexible panel in my garage, not connected to anything. There is no power going in or out, it is on the ground, hence, "safe".

    I have 15 solar panels on the roof of the house. The are "grid tied" and when it is sunny, they can provide a lot of electricity plus there is danger going on the roof because of the falling hazard...

    So... it depends on the solar panel. We don't know anything about the one you're asking about.
