We often see three mistakes on many solar and storage projects. These mistakes affect the long term operation quality and safety of the system. Perhaps since they don't have an immediate effect on the project close out, it's not on the list of priorities for developers. Hopefully by pointing them out, you can get them on your radar conduits in the working space.

We often see three mistakes on many solar and storage projects. These mistakes affect the long term operation quality and safety of the system. Perhaps since they don't have an immediate effect on the project close out, it's not on the list of priorities for developers. Hopefully by pointing them out, you can get them on your radar conduits in the working space.
The code is clear and so are pure powers drawings. You must keep conduits out of the working space in front of equipment. Yet installers still take shortcuts, ignore the drawings and code and install conduits in the working space in front of inverters and panels. This is a trip hazard for those working on the equipment. Enforce the design and codes and keep the conduits out of the working space.
Installers commission their own work. There are obvious conflicts of interest with this, even if the installer is 100% honest and putting the developer's needs ahead of their own companies. There are inherent reasons why they aren't well suited to commission their own work. First commissioning is a different skill set from installation. Second, if they knew they were making a mistake, hopefully they wouldn't have installed it this way in the first place.
Third, it is difficult for installers to objectively test and assess their own work when it comes to their budget and perhaps their employment as a build string is not accurate. It may not have an immediate construction or close out, but it will cause problems for anyone that needs to repair or maintain the system over the next 25 plus years.
This is a big deal, but it doesn't seem to get the respect that it deserves since it's not readily visible. Perhaps this is because the installers know they will be long gone before anyone notices and the developer really has other priorities that they have to take care of at the end of a project. The time saved by not recording actual as build conditions will we paid for ten times and increased own them costs over the life of the solar and storage system.
Hopefully by pointing out some of these big mistakes that are made on projects, pure power can positively impact the longevity of your solar and storage system.
