Of course there are alternatives. But in the event of oil running

When the oil runs outbecomes rare/expensive and all energy costs more,
solar panels will be even more viable because they need no oil to run.

At the same time as they become more expensive to make and buy due to
the increased cost of the energy used to make them.
If you build an oil fired power station you need oil to build it and
oil to run it.
With a renewable energy source you might need oil to build it and then
nothing.
That is what TurNiP can't/won't get his fat head round.
My PV panels will last 25 years without further expense.

Keep that statement in mind when they fail before that. *Even if the panels
don't the control gear will.

The drop in efficiency is less than 1%/year.

assuming you get up to clean them on a regular basis.

Unnecessary unless they are (near) horizontal. The rain washes them
clean.
They will still be producing free energy when fossil fuels cost ten
times what they are now.
