All this is based on my reading rather than actual experience, but as long as the solar radiation is only being applied to the biodiesel as heat, the controlled use of that heat to rid WVO of water should present no problem. (Are you sure the time and temp you gave is correct? It sounds more like a method for pasteurization.)
Edward Beggs is correct that exposure to factors such as light and heat (and air) are not good for diesel-type fuels. If you are consuming as you produce, without prolonged storage, then you probably don't have much to worry about. Given your ambient temperatures and humidity, your biggest problem (if you encounter any) might be microbial activity, but if you use what you make reasonably quickly and have a good fuel filtration system, that shouldn't be reason to worry.
