My new house has a few big windows facing southwest, taking much sun heat
in
the afternoon. Have to keep the heat pump working till after midnight to
cool down.

I went to HomeDepot and hoped could find some kind of window film that can
block sun heat - something like we put on minivan window glass.

It is not clear why you prefer tinted glass to:
-- exterior shade, as by an awning;
-- interior shielding: we fitted Venetian blinds to all
windows facing south.
