RGBW LED Strip Light for Slat Wood Panels Wall

I'm planning on building a wall with slat wood panels. The slats will have a profile on the side which will house the RGBW lights. I'll need around 30 runs of 2.4m RGBW strips so the total length would be approx 80m. What's the best voltage to use on such a long length? Should I go for 12v? Also, can I power everything with just a 1500w power supply? 

Unfortunately, we do not currently sell RGBW LED strip light products at this time. Further, our LED strip light products have a maximum run length that varies between 16.4 ft (5 meters) for our 12V products, to 32.8 ft (10 meters) for our 24V products.

Due to this, our products would not be capable of being powered in a combined run of 80 meters.
