The formula to calculate the total solar panel area is:
\[ \text{Total Solar Panel Area (m²)} = \frac{\text{Average Daily Usage (kWh)} \times 1000}{\text{Average Sunlight Hours (h)} \times \text{Solar Panel Efficiency} \times \text{Solar Panel Power (W)}} \]
The formula to calculate the number of solar panels needed is:
\[ \text{Number of Solar Panels} = \frac{\text{Total Solar Panel Area (m²)}}{\text{Solar Panel Area (m²)}} \]
This calculator helps determine the total area and number of solar panels needed to power a house based on average daily electricity usage, average sunlight hours, solar panel efficiency, solar panel power, and solar panel area.
Let's assume the following values:
Using the formula:
\[ \text{Total Solar Panel Area} = \frac{30 \times 1000}{5 \times 0.18 \times 300} \approx 111.11 \text{ m²} \]
\[ \text{Number of Solar Panels} = \frac{111.11}{1.6} \approx 70 \]
The total solar panel area needed is approximately 111.11 m², and the number of solar panels needed is approximately 70.
