For this system, Solar ATAP delivers about 79% of what NEM would have. You'd generate roughly 423 kWh a month, use 233 kWh yourself and export 191 kWh.

How system size affects your ATAP savings

Under ATAP, using your power beats exporting it, so the extra value of each added kWp shrinks as exports start to exceed what your bill can absorb.

Getting the most from Solar ATAP

  • Don't oversize your system. Unused credits don't roll over, so surplus export is worth less than it used to be.
  • Size your solar around your actual usage, not your roof space.
  • Consider a battery if you use more power at night, since using your own solar beats exporting it.
