Hi Roger, well it sounds like it is doing a great job.
Where we live 21 degrees is as hot as we like our place to be, if it gets above that we open windows.
I did buy some plastic adhesive mirror material once on ebay. Maybe some of that stuck to a flat board or maybe even better to corrugated roofing, would work well.
You may get complaints from passing aircraft about the reflections though.
Is the large tunnel the air collects in insulated. If it were well insulated then it may make an even better heat store.
nice work
