Solar Install with Net billing with Utility

I live near Vancouver Canada and am being bombarded with companies wanting me to install solar.

The interesting part is that the Canadian Govt will provide a $40,000 interest free 10 year loan
to do it.
I have no idea of what it might cost although I do understand solar as I personally installed a system in my motor home.
So here are the facts I have so far.

we use 30000 KWH per year.
I have a south facing roof of 1170 sq.ft The roof is only a few years old and metal so no worries of re-roofing in the near (of far?) future.

I would be interested in comments about how many panels would be needed to provide the required power.
There would NOT be storage involved(i.e. batteries)

This has to be done by a qualified installed(no DIY here)

Your input would be appreciated.

Regards
Fred

Do you know what percentage is your total usage occurs during sunlight hours?

May be a good idea to measure but generally it's around 40-60 percent depending on heating or cooling climate.

Do you have net metering available? Because if you do you can just size to offset 100% of your consumption

You can use this calculator

Yes net metering is available.
