You do have Surya Gharan dosha but not in the 5th house, but 10th house, which is the karamstan or the house of profession. Your lagan is Aries and Rashi is also Aries. Moon is under kemadrume Dosha, which is not good.
You should be doing the below given remedies.
1. Keep fast on Mondays
2. Recite Mantra “Om Gruni Suryaaya Namaha” 108 times daily
3. Surya namaskar
