## Important context

- The estimate is illustrative, not a guaranteed performance result.
- Metro Manila Core uses a typical 15–25% soiling-loss range and can reach a 30% ceiling only when the user selects heavy soiling.
- The calculator does not assume an additional nano-coating generation uplift.
- Actual losses vary with weather, shade, system condition, panel angle, and the type and distribution of dirt.
