After APS explosion injures 4 firefighters, Arizona cities enact battery storage laws for utilities, homeowners

There is an interesting, but non-technical, article in the Arizona Republic about batteries in PV systems.

Most of the major Phoenix area cities have documents that detail the requirements for new solar systems and it is likely that the cities will be updating their documents soon with battery requirements.

First Solar exits the EPC business

SEPTEMBER 20, 2019

Citing the wild success of its Series 6 module, First Solar has announced that it is closing its engineering, procurement and construction business in the United States in order to concentrate on scaling, developing, and selling modules.

There is no further news on the First Solar website, but this seems to be unwelcome news for Tempe.

Japan’s largest floating PV plant catches fire

This is not Arizona, but it is a lesson on how high winds can damage a PV system and produce a serious fire. Kyocera’s 13.7 MW floating project at the Yamakura Dam was damaged by 120mph winds the typhoon brought to the coastal city of Chiba. It appears that the wind caused some of the floating array to break loose and pile up such that there was a short circuit in the wiring that produced a fire.

Waste of good PV modules

The world's first solar road has turned out to be a colossal failure that's falling apart and doesn't generate enough energy

BUSINESS INSIDER has a good article on how NOT to use PV modules in roads. Inaugurated in 2016, in Tourouvre-au-Perche, France, this project has turned out to be a colossal failure.
