PV?

Pretty low maintenance costs.

solar uses a lot of water,gotta keep the panels clean.

Just watched a video.
Every 2 weeks:
Wipe off dust with dry towel.
Wash with towel dampened in water, vinegar, detergent.

That doesn't sound like a lot of water.

then there's inverter maintenance,and if storage batteries
used,battery maintenance. Plus,the hazards of battery chemicals and
lead,along with fire hazard.

Just looked up maintenance procedure for a solar panel
inverter.

"replace every 10 years".

Anyway, it mostly just sits there and pours electricity into the
grid. Pretty cool, especially with this heat, you can imagine
all the air conditioners it's running.

"POURS" electricity? how big a plant is it? how many MW?

1.2MW:

It probably runs THEIR AC and maybe the building lights.

The building is pretty big. The article says it's enough power to power
200 homes.
