Question
Photovoltaic (solar power to electric power) solar panels can be mounted on the roof of your house at a cost per area of $1430/m². You have an electric car that requires a charge corresponding to an energy of 8 kWh for a day of local driving. The solar panels convert solar power to electricity with an efficiency of 10.7% and have an area A. Suppose that the sunlight is incident on your solar panels for 8 hours with an average irradiance of 600 W/m². How much do you need to spend on solar panels to give your electric car its daily charge?Explanation / Answer
power required= 8kWh power from solar cell = A * (600/1000) * 8 * 10.7 kWh equating we get A * (600/1000) * 8 * (10.7/100) kWh = 8kWh A = 15.57 m^2 so cost of solar panels = 15.57 m^2 * $1430/m² = $22274.14
