Connect the wind turbine to the cold solar panels.

Perpetual motion machines have never been accomplished.  Not likely to be
accomplished in our lifetime either.  It goes against a well established
body of physics, both theoretical and experimental.

Heatpump is not against the principles of physics.
All I need to have heatpump to generate enough energy to self-power it.
Where do you see anything against the physics ?

If efficiency of heatpump is 300% , so I only need to use 200% to power
the heatpump on itself.

Right there is your flaw.

If a heat pump takes 3 kWhr to move 15 kWhr between two temperatures, you
can *NOT* get 3kWhr from *any* heat engine operating between those same two
temperatures with just 15kWhr of energy.  To get the 3kWhr to run the heat
pump, you need a heat source/sink that are hotter and/or colder than the
ones your heat pump can produce.

*IF* everything could be made perfectly 'reversible' (no friction, and the
temperature difference from the freon on the heat pump side to the
heat-engine side is zero), then you can *just* (theoretically) get it to
work.  But you would have no energy left over to put into your house.  Made
anything lately that has zero friction?  How do you get heat transfer with
zero temperature difference?

You must consider just how much mechanical work you can extract from the
temperature differences created by the heat pump and the 'heat' that it
'pumps'.  You will always come up short.

if efficiency of heatpump is 300% or more it should be still feasible to
have a heatpump operated by heat energy it self generated
if electric energy operated water and heatpumps are not feasible in this
case, so mayby one powered by "heat" , heat-engine ?
