Problems with solar radiation and heat?
Probleme mit Sonnenstrahlung und Sonnen Hitze?

For two years now I have been struggling with the sun's rays and heat in my apartment. In summer, when the hot days come, it will be unbearable to live in my apartment. I thought about buying an air conditioner to solve this problem once and for all. But the prices are not cheap at all. I don't know what to do now.
Do you have any suggestions for me
