Step 4 cover the ends of each wire with electrical tape a plastic bag or a rubber terminal cover to prevent physical contact should the wires become live.
Safely disconnect solar panels.
Typically the company from whom you originally purchased the panels should perform the work.

Remove any electrical cabling and wires from the roof.
Furthermore installers and solar companies will carry insurance that allows them to cover any damage that occurs in the event of an accident.
Moreover once the solar panels are installed the system is grounded via copper wire to avoid any possibility of shock hazard from touching solar panels even if they are installed in a 1 500 v pv system.
A home solar system that is connected to the utility grid is known in the industry as grid tied and is the most common most simple and least expensive type of home solar system.
Any solar installer or solar company can remove panels for you in order to complete the work safely.
You completely ensure that the system will be totally out and that you will be able to safely access the batteries.
If you live in a developed area with standard electric service and you just want to offset some or most of your conventional energy use with solar electricity you most likely will install a grid tied system.
Disconnect all individual panels from their micro inverters or disconnect the strings from the single inverter.
Remove mounting hardware from the roof.
Remove solar panels from the rooftop mounting hardware and lower them carefully to the ground.
Some larger systems use a solar power disconnect switch for added safety in case one of the solar panels gets exposed to light during maintenance.
Solar safety is just as important as every other subject covered on this site actually much more important.
