June 3, 20224 yr with installation on my panels the company only ground my panels with the power utility ground in the box and not through a spike outside in the ground. is that correct or not

The SANS spec states explicitly that the panels' earth must be separate.
March 27, 20233 yr This is quoted from Sans 10142-1 Solar panel frame and structure shall be bonded to the consumer earth | Clause 7.12

If you bond your earth spikes to consumer earth it means you are using the consumer earth ....

Is there a difference between earthing and bonding? Consider also what the purpose of the earth is, exactly what is being mitigated. Edited March 28, 20233 yr by YellowTapemeasure typo
March 28, 20233 yr Google Mike Holtes on you tube regarding earthing and bonding. Very good explanation. He regognise that few people understand the difference. You kinda have to understand electrical theory to understand how it works he states. Also, lightning protection is different to earthing and bonding. I Agree, the question is what are you trying to achieve.

I Agree, the question is what are you trying to achieve. Yes, I am familiar with Mike Holt's training videos, they are excellent. In fact, I watched his grounding and bonding video a few times, eventually made some notes 😁 Edited March 28, 20233 yr by YellowTapemeasure
April 24, 20233 yr A very belated answer. BUT. The standard do not state that. Para 7.12 has many sub paragraphs and none of them state what the guys above says. I hate it if someone pretends to quote a paragraph and he obviously has not even read it. (YellowTapemeasure, where in 7.12 ???) I have just done an intensive study of 10142 specifically with this in mind. The deciding factor is that panels are double isolated devices, which means there are sufficient separation and makes that a useless exercise.

Hi Marius (love your very helpful videos) - I have a remote (Cederberg mountains) install coming up where Inverter/battery and solar array will possibly be 100m removed from each other. The array is quite exposed to possible lightning strikes. Are you saying that an array grounding will not be required? Also, what would your opinion be on the positioning and earthing of the DC Protection box installed at the array vs installed at the Inverter/Battery/DB location? The electrician will have to install a grounding rod or equipment at the inverter/Battery/DB location. Any assistance from yourself or members will be appreciated.
May 4, 20233 yr Regarding your question, the method of grounding your solar panels will depend on the specific requirements and regulations of your area. However, it's common for solar panels to be grounded both to the power utility ground in the box as well as a spike outside in the ground. If you have concerns about the grounding of your panels, it's always a good idea to consult with a licensed electrician or solar panel installer who can assess the installation and ensure that everything is done according to the necessary standards. In terms of fixed energy tariffs, there are many companies in the UK that offer this type of plan. Fixed energy tariffs are beneficial because they provide a stable price for your energy usage, which can help you budget your monthly expenses more effectively. Some popular energy providers in the UK that offer fixed tariffs include EDF Energy, ScottishPower, and British Gas. I hope this information helps!
