Simulated Seasonal Profile
Define theoretical consumption based on appliance models or manual estimates.
| Appliance | Power | Hrs/Day | Months Active | Avg Day Wh | Actions |
|---|---|---|---|---|---|
| Refrigerator | 150 W | 24 h | All Year | 3,600 Wh | |
| Air Conditioner (1 Ton) | 1200 W | 8 h | 5 Months | 4,000 Wh | |
| LED Lightsx8 | 10 W | 6 h | All Year | 480 Wh | |
| Television | 100 W | 4 h | All Year | 400 Wh | |
| Microwave | 1000 W | 0.5 h | All Year | 500 Wh |
Real Utility Data (Baseline Apartment)
Input actual historical utility bill data to compare against your theoretical model.
Values are entered in total Wh per month to match standard utility bills.

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.
