It seems natural to set up solar kytoons supporting the solar cells. In this case the dynamic lift of the kite of each solar kytoons is added to the aerostatic lift generated by solar energy.
Thus a part of the received solar energy is converted into heat producing the aerostatic thrust (transparent and/or black envelope and with a reflective insulating part) while another part carrying the thin film solar panels generates the production of electricity which is conveyed by the tether.
When the night falls, the production of electricity stops, but the intermittency is predictable and therefore more easily manageable: batteries would be installed at the ground stations or, better, other energies would take over, or the surpluses would be exported, or partnerships would be made between countries located at the antipodes among other possible partnerships.
Of course the solar thermal balloon generates less thrust than hydrogen, although this thrust would not be negligible at altitude (less clouds, more radiation), but a larger balloon is not a disadvantage insofar as it supports more solar cells and more kite area which benefit from more powerful and regular high altitude winds. Moreover the thermal solar, which fits perfectly with the solar panels, does not involve the dangers of hydrogen and the problems of maintenance of all the gases lighter than air.
Airborne solar wind energy systems (ASWES) could be the family name of this devices, while solar kytoons (SK) would be their first name.
