All power plants have maintenance costs.

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 Â* there's Â* inverter Â* maintenance,and Â* if Â* storage Â* batteries
used,battery maintenance. Â* Plus,the hazards of Â*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. Â*Pretty cool, especially with this heat, you can imagine
all the air conditioners it's running.

"POURS" electricity? Â*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. Â*The article says it's enough power to power
200 homes.

You need to know that is MWp (p= peak)

No I don't.

So much less in cloudy weather. Nothing at night.
They may achieve peak output for four hours on a good day.
One hundredth of that when there is heavy cloud or rain.

So?
