Audited planning profile
This team ten-year profile applies a 8× editable baseline across 120 model periods to the home lighting breakeven model.
Compare the break-even period with the time you realistically expect to keep or use the option. Use measured team throughput and include coordination time and unavailable capacity. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten years.
Local tariffs, taxes, seasonal efficiency and regulated charges are not inferred automatically.
Check a recent bill, device specification and current tariff before committing to a purchase or retrofit.
