Hallo Technicians

I have already installed my solar panels as per picture I have provided.

All information is stated in my picture. I didn't put in the grounding cables before installing 

My questions are as follows:

1. As the grounding holes (5) are hidden underneath the panels, how do i access them to install the ground cables, is it a must to ground them through the grounding holes provided?

2. I don't want to drill new holes as they will compromise it's warranty

3. Since I use the Aluminum rails, aluminum clamps, can i just connect it via the rail only, using the ground lugs?

4. What other advice can I get from this

I am looking forward for good advices since yiu are helpful in this group

Thanks

Every panel has to be individually grounded to a grounding wire (according to regs), so you will either have to drill new holes to fit a grounding wire to each panel or take it apart and add the grounding wires to each at 5.

Does this ground go to DB or earth spike?

Both will work. 

If you choose an earth spike, make sure the earth spike is bonded to your DB (installation) earth so that there is only one earth.

Thanks. A bit off topic but if you say bonded i'v got a 2 bedroom cabin 10m from my house connected by a doubled 4core 4mm surfix cable. Is the thin earth wire connected to the house DB  enough?
