Problem

An off-grid cabin’s refrigerator requires about

1.0\,\text{kWh}

of electrical energy each day. Identical solar panels each deliver a steady

150\,\text{W}

for

6\,\text{h}

of peak sunlight per day. Neglecting all losses, what is the minimum number of panels needed to meet the refrigerator’s daily energy requirement? a)
