There are some fantastic apps to help you locate the path of the sun all year round. You can calculate A at the equinox, summer solstice and winter solstice using the second set of formulae if you know your latitude (the number of degrees north or south of the equator that your site is). With the formula above all you need to know is H (the height of the thing casting the shadow) and A (the angle of the sun at midday). Do some mathsīy taking a few measurements you can calculate the exact length ( L) of the shadow cast at midday by any object such as a tree, wall or building. Take note of where the shadows are and which part of your garden is in shade and which part is in sun. Take a camera with you and photograph your site at mid morning, noon and mid afternoon at midsummer and mid winter. Here are seven of the best ways we know to better understand the movement of the sun at your place. If you want to maximise plant productivity, minimise your energy use and ensure everyone is comfortable all year round your permaculture design must take into account the position of the sun in the sky.īy creating even a basic map that shows the areas of year-round shade and year round sunshine you can place of all kinds of elements into your design with confidenceīut how do you find out where the sun moves in relation to your garden & home. It’s not just our gardens and our homes that can benefit from thoughtful solar design, animals like winter warmth and summer shade too.īeehives, chickens, fish ponds, livestock and even our family pets appreciate sunshine in winter and shade in summer. Solar hot water panels are exactly the same and every home outside the tropics can benefit from having more winter sunlight entering the living spaces. Solar panels need maximum exposure to the sun to harvest the most energy they can. Other elements of your permaculture design need sun too. If you want to design a resilient future & permaculture life for yourself, bring it on, we’re ready to help you get the skills. This how-to is part of the resources from our Permaculture Living online course with Milkwood founders Kirsten Bradley & Nick Ritar & permaculture co-originator David Holmgren. If you want healthy veggies or sweet fruit, you need to place your gardens, greenhouses and orchards where they will get adequate sunshine for the parts of the year that they are growing or fruiting. When you’re creating a permaculture design, mapping where the sun falls on your site at different times of the year is central.
