How Many Solar Panels to Charge a Car?

Solar panels are the best option for charging an electric vehicle (EC). As they are easy to use, several people go for this option. Ev required solar panels, a maximum of 12 and a minimum of 8, to charge itself. Solar panels requirement exists in various formats, i.e. it depends on multiple factors.

So now the question arises, what is the need for solar panels? Solar panels with EV charging stations provide several benefits and are inexpensive.

They are used to charge various electronic items because solar panels are eco-friendly and provide an inexhaustible energy source.

How Many Solar Panels Needed to Charge a Car?

5 to 12 panels are required to charge EV. Let’s consider an illustration to understand the concept ~

It is obvious that we require 9.96 kWh of electricity per day to charge, so by this concept, we get to know how many panels are the requirement to charge an EV.

Above all, we must find out how much electricity a single panel produces. The ratio that we obtained is based on the wattage of electricity of the panel and the amount of time light of the day it receives each day.

The formula to calculate is ~

Per day – Hours of daylight x wattage = Watt-hours per day

By this, we get to know about the output of a panel per day, the output ranges between

250 to 400 watts.

But 400 W proved to be considered standard one.

Sun hours each day range from 3.5 to 6 in the US on average, 4.5 hours a day or more in other countries. We will use 4.5 to be conservative

  • 5 hours of sun presence per day x 360 Watts = 1,620 Watts per day, or to be considered as 1.62 kWh per dah

Now we get to know how much electricity can be produced by a single panel, now we can easily find out the number of panels required to charge an EV, and the equation is ~

Finally, divide the kilowatt hours of electricity required by the daily kWh output of each panel to obtain the number of panels needed to charge an EV.

9.69 kWh per day / 1.62 kWh per panel per day = 5.98 panels

Manufacturer and Type of Solar Panels We Choose

Several solar panels are available in the market. Some of them are:

  • Monocrystalline Solar Panels (Mono-SI)-
  • Thin-Film: Amorphous Silicon Solar Panels (A-SI)

Solar Panel and EV Charging systems

A photovoltaic (PV) panel absorbs solar radiation and converts it into electrical energy to power electric car batteries. A vast array (300) of electrically linked solar panels would be set up at rapid EV charging stations to produce the requisite electricity to charge electric cars in a day.

Charge an EV With a Solar Panel

1. At Home

One way to do so is to install a panel at your home to start supplying energy to your equipment using solar panels. You can then charge the battery during the day using solar energy.

2. At Publicly

We can charge our vehicles with solar batteries. The excess energy of solar panels can be stored in the solar battery and later charge your electric car.

Energy for EVs is Required to Get Fully Charged

The measuring term is kWh. If you consume 2kW of power for 2 hours, you consume 2kWh or 2 units of electricity.

Battery Size For an EV Sample

The average electric automobile battery capacity ranges between 60 to 100 kWh. Automakers are extending battery capacities to unbelievable numbers like 130 and 200 kWh. EVs with 16 or 20-kWh batteries can’t compete anymore.

Solar Panel Efficiency

Solar-cell efficiency is the percentage of sunlight energy a solar cell can convert into electricity using photovoltaics. The effectiveness of solar cells in a photovoltaic system is affected by latitude and climate.

Pros of Solar Panels

It has numerous benefits it helps to charge our various electronic items, that can be possible because it contains high wattage of Electricity to run different appliances, especially on the summer days its wattage increases, the sun produces more heat and energy that is beneficial for all of us to work with solar panels more accurately on the summer days.

Cons of Solar Panels

Everything has pons and cons with them It also has some cons that solar panels are laid on the roofs of the houses, Indian climates are not the same throughout the whole year, so in the summers there are no issues because the sun shines brighter all day long but In raining season water and hailstorm damage the panels a lot which can only be replaced and add on the extra amount on the shoulders of the individual.

Solar Panels to Charge a Car – FAQs

1. How many solar energy storage batteries are recommended?

Ans: We require 4 to 5 solar energy batteries in our household to charge our electronic. types of equipment and electric vehicles

2. How to get the power from your solar panels to your car?

Ans: When you already have a solar system in your home, you only need to establish a home electric vehicle charging station.

3. How much electricity do leading EVs require per charge?

Ans: The measurement is done in kWh. If we start consuming 2 kW of power for 2 hours that means you consume 2 kWh or 2 units of electricity.

4. How much solar power does it take to charge EVs?

Ans: The answer is simple it required 5 to 12 panels were required to charge EV.


Sometimes, it proves to be costlier but it decreases the harmful impact of carbon emissions on the environment and helps to maintain the environment green and clean. It also saves the money which is earlier used for fuels in automobiles. The amount of energy we will require for EV is based on various factors such as size, and number of miles driven each day, but Using solar panels to charge your automobiles with your home panels will help you save a lot money. Its initial cost sometimes remains high but ultimately impacts the environment and our wallets by reducing the dependency on fuel to run automobiles.
