Tubular solar water heaters have spaces between the tubes. When the sun has a high transverse angle to the collector, this is not a problem, since barely any light escapes through the cracks. However, when the sun is perpendicular to the collector, more light escapes through the spaces between these tubes. Adding reflectors to your collectors will reflect the majority of this missed light back up into the back of the tubes, thus adding to the amount of sunlight collected.
