Early in the year I posted “The Sun Will Come Out Tomorrow” – to say that I’d be sharing with you the progress of our solar power installation and the ‘handover’ of that project to operation.
So, here’s a quick update on our solar power installation.
This week we got our system online and generating power! So far we are averaging over 20kWh per day. Vivint, the company which installed the system, has an app which provides details including the savings (earth savings, such as reduced carbon use). See the screenshots below:
We had hoped to be generating power weeks ago, however a new standard was established in our town regarding the position of AC and DC runs into the system (see photo, with highlighted area of the two inputs which had to be swapped).
The installers were not aware of the new town requirement. So the system failed inspection (even though it worked perfectly and would have passed if the inspector hadn’t happened to have gone through a seminar just a couple of days ago).
So, Vivint had to come back and re-wire the system, which they did fairly promptly, but now the town had to schedule a re-inspection.
Bottom line: this cost 3 weeks of unexpected delay.
This is a good example of estimation optimism bias. There are also some communications issues here, right?
However, the good news is that the system is up and running and I hope to follow up next with an ability to talk about the monetary aspect of the project. Yes, we did this for the right reasons: economic and ecological. We have started to see the ecological benefits, but as they say: show me the money!
I should have that update in a month. Or.... am I being too optimistic in that estimate?
