The 7 questions finance teams actually ask

CFO-grade FAQ

No fluff answers. If it can't be resolved with a number or a clause, it doesn't belong here.

Degradation modelled at 0.55% / yr (Tier-1 panels), tariff escalation at 3.8% CPI-linked, with a ±15% sensitivity band on every number.

End-to-end. Embedded generation apps for >30 kW take 45 days; we pre-lodge on day 1 of design to protect the timeline.

Our contracts include a performance guarantee. If the system under-delivers by >10% against modelled output, we remediate at our cost.

Yes — PPA (zero-capex), chattel mortgage and operating lease all available. We structure to match your FY budget.

No. Every installer, electrician and commissioner is employed by Next Phase Solar. Names are on the safety plan you get at signing.

Year-1 monitoring and quarterly performance reports are included. Extended O&M packs from $180/kW/yr with SLA-backed response.

We don't play quote-matching games. What we'll do: audit their scope line-by-line and tell you exactly where our numbers differ and why.
