How Many Solar Panels Does It Take To Charge an EV?

Charging an electric vehicle (EV) with solar panels is one of the most cost-effective and environmentally-friendly choices available today. By harnessing the power of the sun, you can significantly reduce the cost of charging your car while also contributing to a cleaner environment. However, the question on many homeowners’ minds is, “How many solar panels does it take to charge an EV?” This is a great question, and the answer depends on several factors, such as the type of EV, driving habits, and the solar panel system itself. In this guide, we’ll break down everything you need to know about charging an electric car with solar power in Arizona.

How much energy does it take to charge an EV?

Charging an electric vehicle (EV) requires a specific amount of energy, which is typically measured in kilowatt-hours (kWh). The energy needed to fully charge your EV will vary based on factors like the battery capacity of your vehicle and your typical driving habits. For instance, most electric vehicles require anywhere from 20 to 100 kWh of energy to fully charge. A small city car may need around 20-30 kWh, while a larger vehicle with a bigger battery, such as an SUV or luxury EV, could require 60-100 kWh.

How many solar panels do you need to charge an EV?

Charging your EV with solar power depends on a number of factors, including the size of your solar panels, your car’s battery capacity, and the number of daily driving miles. On average, a single solar panel can generate around 300 watts of electricity per day, which is about 1-1.5 kWh of energy. If you drive around 30 miles a day, you’ll need a solar panel system that can generate at least 10 kWh of energy per day to fully charge your EV. This typically means installing around 6-10 solar panels, depending on their efficiency and your vehicle’s energy requirements.

Everyone’s solar EV charging situation is different

One of the top reasons to charge your EV with solar panels is the environmental impact. By relying on solar energy, you reduce greenhouse gas emissions, making it an eco-friendly option compared to charging from the grid. Additionally, solar energy is renewable, so you’re tapping into a long-term, sustainable energy source. Over time, solar charging can also save you money, especially with federal incentives and rebates available for installing solar panels.

Why charge an EV with solar panels?

Charging your EV using solar energy is far cheaper than relying on grid power or public chargers. The average cost of solar electricity is between 6-8 cents per kWh, while grid electricity typically costs about 16-17 cents per kWh. This means that solar charging is up to 50% less expensive than using grid power. Additionally, public chargers can cost as much as $0.40 per kWh, making them five times more expensive than charging with solar energy. In the long run, choosing solar power for EV charging helps you save thousands of dollars annually.
