Navajo Nations first solar project is producing enough power for about 13k homes (azcentral.com)

It appears the cost was about $2.20 per watt: it cost $60M and is rated 27.3 MW (https://nativenewsonline.net/currents/kayenta-solar-project-...)


Seems kind of expensive. Isn't more like $1/watt the norm?


You've got to compare solar powered apples to solar powered apples.

The article reads as though the $60 million is fully installed and commissioned.

Sounds like your $1/watt is for the panels only?


$1/watt is the current price for modules and installation, etc. can bring it up to $2-3, but for a large-scale installation of this size I would expect that you could get a discount on the panels and the total cost could be under $2 although I was not able to find any current figures for the going rate Arizona.

What I might be more concerned about is that their agreement to sell power is only for two years. Without storage, they may have a hard time getting good prices for mid-day power in the near future.

Edit: Probably $1.50/watt for utility scale: https://pv-magazine-usa.com/2016/09/29/nrel-u-s-utility-scal...


That chart shows cost per watt for a 100 MW utility scale project. Smaller projects like this one tend to have higher costs per watt even if they're also in the multi-megawatt "utility scale" class.


Module cost this year is about $.35/W.


Right, but the solar panels aren't much use to anyone sitting in a dispatch bay at the manufacturer in China.

You'll probably want to get them freighted to the installation site, screwed down to a support frame, wired up to an inverted, connected to a load and / or the grid.

This may drive the price up somewhat.


> The contractor hired and trained about 200 Navajos to build the plant, said Deenise Becenti, a spokeswoman for the tribal utility, leaving a qualified workforce for other projects.

This will be interesting to see how it plays out in future projects. I also wonder what they received for training / certifications. It was probably a requirement of their TERO.
