1kw/m^2 is the "standard" rule of thumb for heat energy from solar irradiation. I'm unsure whether OP has done the calculation (in which case, credit to a well built system) or simply cited the standard rule.
There are some large Stirling engines out there that operate on hot oil. With a large diameter piston, quite a bit of torque can be generated with even small ∆T. Oil can be heated as with traditional solar water heaters (i.e., with no concentration), though concentration doesn't hurt.
- remipch 2y agoI have developed a simple simulator [0] to estimate the theoretical power received by the target for a given hardware configuration: - the global position on the planet - the date and time - the size and position of some background elements - the number, size and position of the panels in the grid The solar power estimation uses : - the Python code provided in this article [1] to estimate position of the sun (thank you John Clark Craig) - the simplified formula [2] to estimate the direct insolation from the sun position - a custom light projection implemented using Panda3D game engine [3] [0] https://github.com/remipch/solar_concentrator/blob/master/software/simulator/README.md https://github.com/remipch/solar_concentrator/blob/master/so...
