List each device → note its power (W) → estimate daily run‑time (hours) → compute Wh = W × hours → convert to kWh (Wh ÷ 1,000) and sum. Add 10–20% for “phantom”/future loads. Example (lean 2‑bed prefab): Look at the last 12 utility bills and note the highest‑use months (kWh).
The daily kWh generation of a solar panel can be calculated using the following formula: The power rating of the solar panel in watts ×-- Average hours of direct sunlight = Daily watt-hours.
