A preliminary surface water study was undertaken as part of the project’s feasibility study. The results showed that surface water traversing the site is generally slow, shallow and wide spreading. Given that the solar structures are elevated 2m in height and supported by poles, the large clearance underneath the structures will ensure that water can flow through without any issues. Any weeds found around the solar panels would be controlled on a regular basis. Sheep grazing within solar farms, which is common practice around the world, is the most effective and environmentally friendly way to control weed growth. In addition to grazing sheep, Waroona Solar Farm would also employ labourers from time to time to manually clear and control the weeds.
