Hi there,I'm curious if folks could share their experience with decommissioning existing ground mount residential solar arrays? Do you typically cover the panels with blankets or tarps while doing this to ensure very low voltage? I'm just curious what the best practices are!
Hi Riley,The key thing to check before working on any system is if there are any faults. Check all strings.If you find no faults, you can safely work without covering the array. But never touch any frames, metallic structures, etc. before you have first checked for ground faults, etc. (this goes for any array you are working on for whatever reason). If there are faults, then you may want to cover the array with black plastic or make key array electrical disconnections after dark.A lot of older PV systems that were installed 20+ years ago were never code compliant, so decommissioning can be a bit more sketchy for these older systems and you should be extra cautious.Generally PV systems are going to work ~30 to 40 years before they need to be decommissioned.Stay safe
Wow! That's incredible to hear about. I just read the Wikipedia article as well and was impressed with all the entities that came together to pull that off. And the fact that each battery was 1200 pounds! Things really have advanced quickly in the last 40 years, that becomes clear when I read stories like that one. I definitely would have been afraid of decommissioning that as well - I find the little systems a little scary, let alone the ones with big battery banks. You've had quite a career in solar it sounds like - and have gotten to see a lot of things. I don't think I know what EVA is also.And, UV inhibitors are some sort of chemical additive in the PV cell creation process I take it?Interesting stuff, I appreciate you sharing.Riley
