  • You can harness the power of the sun's rays to charge your electric vehicle. Here's how many solar panels you'll need to do it.

The article from MSN discusses how to determine the number of solar panels needed to charge an electric vehicle (EV). It explains that the calculation involves several factors including the EV's battery capacity, the average daily mileage, the efficiency of the vehicle, and the local solar insolation (the amount of solar energy received per unit area). For instance, if an EV has a 60 kWh battery and you drive 30 miles daily, with an efficiency of 3 miles per kWh, you would need about 10 kWh daily to recharge. Assuming each solar panel produces around 300 watts under optimal conditions, and considering you need to account for losses and inefficiencies, you might need around 12 to 15 panels to cover this daily requirement. The article also touches on the importance of considering seasonal variations in sunlight, panel degradation over time, and potential future increases in driving needs. Additionally, it suggests looking into local incentives for solar installations which could affect the financial feasibility of such a setup.
