| ## How This App Works: | |
| - The app asks for the number of each device (Fans, ACs, Lights, etc.) and their wattage to estimate load. | |
| - Based on your inputs, it suggests the number of solar panels, battery capacity, inverter, and DC cable requirement. | |
| - Three system types are available: **On-Grid**, **Off-Grid**, and **Hybrid**. | |
| - The app takes into account whether your building is a single-story or two-story structure for more accurate recommendations. | |
