That is not a great idea first of algae would probably grow like crazy,also temperatures would fluctuate too much
What are the dimensions?in preparation for moving I may have made a teeny tiny mistake/misjudgment in buying a 300 gallon double bow front tank and stand that for some reason without thought, thinking it would somehow fit inside my house (which it does not)
Exactly so think about how much worse it would be outdoors you would have to spend long hours scrubbing algae100% agree with @Tank seeker one of my old tank(tore down now) was in my house's sunroom, the light would shine right into the tank and there was always algae on the glass and on decorations, was not fun to deal with. Keep in mind, this tank had a full-grown bristle-nose pleco, so even tank placement inside your house can lead to algae problems due to sunlight
