So this is a business buying this? Interesting. That must make the figures
even better.

Cost of this installation?
Cost of local electricity per kilowatt hour?

It has already been spring for two of those
eight weeks.
In the summer you will produce more power than you
can use, but in January not enough.
I have about 3 m2 on the roof of my trailer. With LED light
fixtures and gas heat and cooking it produces
enough. After a few months of
operation the inverter died. I had to remove it (big job)
to repair it. When I repaired it, I found a design flaw
in the inverter. It needs to draw about 100 amps to power
the microwave, and the wires and connectors in the box
are not big enough. The connectors melt and produce smoke.
Solar panels are not zero maintenance. They gradually become
covered with dust which reduces the efficiency. They need to
be accessible for cleaning, and they need to be cleaned regularly.
Solar power pays in some places but not others. A person needs
to be aware of all the issues add things up carefully. Good
luck with your project.

Poor Planning, and believing the Sales-Droid hype, in the first place....
Anyone with any BRAINS, at all, knows that you NEVER run an Inverter,
over 1Kw from a 12VDC Battery system, and expect it to survive.....
UNLESS, it is a quality Unit like a SW, or DR, Trace or an OutBack....

No salesman talked me into this. It was an experiment. I guess you
think it is stupid to try something and report the results? Smart
people only spend their time cutting others down, eh?
The inverter was rated for it. It was not cheap. The
batteries were special and held up, but they are high maintenance
golf cart batteries.
The biggest problem was finding a low power microwave. Time after
time I found the power consumption numbers stated in literature
to be wrong. If I could have found a 550 watt microwave like I
planned, everything would have been fine. My first microwave
was that size, but they don't seem to make them that small any more.
