- Page 9 Collector Position Avoid significant shade from trees or other buildings falling on the solar collectors three hours before or after midday. Minor shading from antennas or flues will not affect solar collector performance. Mount the solar collectors as close as possible to the hot Latitude water storage tank to minimise pipe runs and heat loss.
