Summer-Solstice Solar Arc of Trees for Free Harvest of Shade & Cooling

See how this ideal orientation of home and landscape trees (in water-harvesting basins) to the sun—plus appropriately sized equator-facing roof overhang—maximizes the on-site potential to freely/passively harvest cooling shade in summer, generate rooftop-solar power & solar hot water year round, while also maintaining ideal solar access in winter.

Compare this Summer video to the “Winter-Solstice Solar Arc of Trees for Free Harvest of Sun & Heating” video to see how this orientation of home and landscape works for all seasons.

Note 1: Spacing from east wall to east trees is 10′ (3 m). West wall to west trees is 10′ (3 m).
North arc of trees ranges from 13′ (4 m) to 20′ (6 m) from the north wall.

Note 2: This video is for 32˚ N latitude.
For sun and shadow paths and angles for other latitudes, plus additional strategies for the free/passive harvest of sun and shadow, see the book Rainwater Harvesting for Drylands and Beyond, Volume 1, 3rd Edition available at deep discount direct from the author.
