Solar array output:
\[ \text{solar array output} = \frac{\text{electricity consumption}}{365 \times \text{solar hours in a day}} \]
Solar array size:
\[ \text{solar array size} = \text{solar array output} \times \left( \frac{\text{bill offset}}{\text{environmental factor}} \right) \]
Required panels:
\[ \text{required panels} = \frac{\text{solar array size in kW} \times 1000}{\text{panel output in watts}} \]
Area occupied:
\[ \text{area occupied} = \text{required panels} \times \text{panel width} \times \text{panel length} \]
