A couple months ago I posted a photo (not a very good photo) of a Phnom Penh tuk-tuk equipped with a solar panel and wondered what the panel was powering. Here is a birds-eye view of another tuk-tuk with another panel, a bigger one, so the idea is catching on. The question remains, though, what the solar power is directed to since lighting is an after-thought, a non-essential on vehicles in Cambodia. If you have lights front or rear, or both, that is fine. If you don’t have lights, that is fine, too. Notice that this tuk-tuk has a non-functioning light on its upper right.
