His appearance is somewhat the same as the other forms of BoBoiBoy, having cropped black hair and the same physical bodily features, but BoBoiBoy Solar sports a predominantly yellow/orange and white color scheme with his clothes. His cap that's angled with its bill slightly to the left is white in color with neon yellow swirl-like patterns on the bill, his insignia (a yellow star-like symbol) on the middle, the three 'dinosaur horns' decorating the top of the cap being yellow. His vest is mostly white with yellow/orange linings on the hoodie and front pockets. He also wears a white shirt underneath with the sleeves rolled up to his biceps. Unlike the other forms, BoBoiBoy Solar wears white gloves and his white/bright golden eyes rest beneath yellow/orange tinted sunglasses. His orange power band worn on his right wrist. Yellow/orange pants with horizontal wavy white lines decorating the upper half of the right pant leg and white sneakers laced with orange shoelaces to complete his attire.
Although none of Solar's personality has been shown onscreen, according to the fanmails, Solar apparently wears glasses to look 'cool', implying that he might be a suave and calm individual.
According to Nizam Razak, each of the two BoBoiBoy Forms will be polar opposites: BoBoiBoy Thunderstorm as aggressive and fierce while BoBoiBoy Cyclone as cheerful and happy; BoBoiBoy Fire as hot-tempered while BoBoiBoy Water as calm. Since BoBoiBoy Thorn is naïve and takes things literally, it is likely that BoBoiBoy Solar is smart and wise.
