Yes, here in South Limburg in the Netherlands a lot of homes have these installed and I guess keeping the sun out is the best option, whether it be awning or roller shutter.

We have solar reflecting blinds, and keeping windows and filters shut helps quite a bit. Solar reflecting blinds are still heating up the window panes though. Temperatures inside still up to 30°C (86°F) in heat waves as we also have a flat roof that we insulated last year, heat build up day by day. We went checking on awnings, but good ones are quite expensive, we went earlier this year for a split unit AC.

We also use a sun umbrella on the balcony door which has the largest window pain, it definitely helps, maybe a cheap/quick solution instead of awnings.
