Wollongong Escarpment Shading and Illawarra Solar Performance

The NSW Energy Savings Scheme (ESS) provides additional incentives for eligible Wollongong households. Wollongong's Illawarra escarpment may shade some properties on the western side of the coastal strip during afternoon hours, a shading analysis should be part of any solar site assessment for escarpment-adjacent Wollongong properties. The escarpment also creates some afternoon cloud formation that can reduce generation in the western suburbs. Coastal and north-facing Wollongong roofs typically perform better than escarpment-facing or westerly-facing roofs. A professional solar site assessment by a CEC accredited installer should identify shading impacts before system sizing is finalised.
