Question

How much electrical energy we can produce by solar stirling engine and how we can make lense for that?

Answer 1

Your question is very confusing. Please clarify.

Answer 2

A stirling engine (like most heat engines) will convert about 30% of the heat energy on it into motion.  That motion can mostly be converted to electricity.  

A fresnel lens or a parabolic reflector could focus the energy, and if the lens is rotated around a fixed engine, there need be no flexible tubes or wires to the engine.
