ViewSolar in Adelaide Hills: questions
Do bushfire zone rules affect my solar install?
Yes - Hills properties classified BAL-12.5 or higher require non-combustible cabling protection (steel conduit) and specific isolator placement. Your installer should handle this in the design phase.
Is off-grid worth considering in the Hills?
Yes for blocks more than 200m from the grid or where the SAPN connection quote exceeds $30,000. Off-grid Hills systems often pay back faster than the grid connection cost.
Will tree shading kill my solar yield?
It will reduce it. Microinverters or DC optimisers help manage partial shading (the worst-shaded panels no longer drag the rest down). Tree trimming and panel placement are the other levers.
