Add each appliance with its power rating, quantity and how many hours a day you use it. The calculator keeps connected load (the power your equipment draws) separate from energy consumption (the electricity you actually use over time), because those are two different things and solar sizing depends on the second one.
| Appliance / Equipment | Power (W) | Qty | Hours / Day | Energy / Day | Remove |
|---|
| Connected load | Running power, in watts |
| Daily / monthly use | Energy consumed, in kWh |
| System size | Generation capacity, in kWp |
| Panels needed | Modules at the rating you chose |
| Battery storage | Capacity for your backup window |
Connected load tells you whether your supply is single-phase or three-phase. Consumption tells you how much energy solar has to replace. Solar sizing follows consumption, not connected load.
A calculator is a good starting point, but it cannot see your roof, your shading, your structure or your tariff. Send us your estimate and we will turn it into a proper design.
