Simulated Seasonal Profile
Define theoretical consumption based on appliance models or manual estimates.
| Appliance | Power | Hrs/Day | kWh/day | Months Active | Actions |
|---|---|---|---|---|---|
| Refrigerator | 150 W | 24 h | 3.6 kWh | All Year | |
| Air Conditioner (1 Ton) | 1200 W | 8 h | 9.6 kWh | 5 Months | |
| LED Lightsx8 | 10 W | 6 h | 0.48 kWh | All Year | |
| Television | 100 W | 4 h | 0.4 kWh | All Year | |
| Microwave | 1000 W | 0.5 h | 0.5 kWh | All Year | |

Complex Scaling
Scales the single apartment profiles to the full building.
Solar Assumptions
Daily hours of equivalent full sunlight (e.g., Mexico averages ~5.5h).
Accounts for inverter losses, wiring, dirt, etc. (typically 75-85%).
Rating of a single solar panel you plan to use.
How it's calculated:
- We calculate the annual average daily Watt-hours based on your monthly profiles.
- Multiply by 20 apartments.
- Divide by peak sun hours (5.5h) to get RAW required solar output.
- Divide by efficiency (0.80) to compensate for real-world energy losses.
