How Many Solar Panels To Charge A Tesla?

Solar energy has grown in popularity as a way to provide environmentally friendly power to one’s home over the last decade. People have discovered significant value in being able to add to their electricity costs. And also contribute to an environmental cause, and even be more self-reliant by setting up electrical systems that are actually off the grid because of this accessibility.

Tesla has filled one of the most significant gaps in the automotive market by developing one of the most widely used electric cars on the road today in conjunction with this major shift among consumers to renewable energy.

Tesla has created an all-electric vehicle that is faster and more luxurious. Many of its gas-powered counterparts through remarkable engineering achievements. Elon Musk, the entrepreneur who also launched other green-forward and society-benefiting firms, is not stopping at electric automobiles. 

Elon sees the creation of a green energy future state that empowers people to power their homes and cars. Using renewable energy sources on their own as a key step toward achieving this objective. One of the most important methods to get there is to enable a system where consumer solar panels help Tesla charge, effectively lowering the cost of driving tesla to zero.

Can You Charge The Tesla With The Solar Panel?

Many homeowners are asking if they can charge their Tesla automobile with solar panels, and the answer is yes. Solar energy may be stored in an electric vehicle such as a Tesla by using its battery. Musk has described his newest objective, which he claims can be accomplished with his one-two punch solution for homes seeking alternatives to fossil fuels:

  1. Install solar panels on your home to produce electricity by utilizing the power of the sun.
  2. Take that solar energy and charge your Tesla Model S with it.

Before the Tesla-SolarCity merger, was this all feasible? Of course. A Chevrolet Volt or a Nissan Leaf driver did not require Elon Musk’s “master plan” to see that electric vehicles may be utilized with solar power. However, perhaps Musk’s most significant contribution was his insight. That solar panels and electric cars are mutually beneficial rather than competitive goods that need to be compared.

You might be able to construct a scenario where a tablet and a phone are seen as substitutes. But Steve Jobs successfully shifted demand away from tech’s power users and toward consumers who need both. Similarly, Musk’s latest action is intended for the average homeowner, going beyond clean energy’s early adopters. Who years ago linked their Nissan Leaf or Tesla with solar panels at home.

How Far Does An Average Person Commute To Work?

The energy needed to charge a Tesla with solar panels is not precisely the same as the energy required to keep it charged. For some vehicles, it might be around 100 kWh, which is an enormous amount. To put it another way, a US home’s average monthly energy usage is about 90 kWh. We should not assume that a Tesla battery will ever be entirely depleted in real life; this does not take place.

According to the American Automobile Association, the typical US commuter travels only 30 miles each day. The Tesla Model S has a range of 402 kilometers, which means that 30 miles are about 6.5 percent of its entire battery capacity. Let’s double this to be safe and use a 60-mile journey. Or 12% of a Tesla Model battery capacity of 85 kWh, or 11 kWh. The solar panel array needed to charge a Tesla Model S should be able to provide 11kWh worth of electricity.

Tesla Design Parameters

We must first figure out how much energy is consumed when charging a Tesla before we can determine how many solar panels are required to build a closed-loop charging system for one. To figure out how much power will be needed. We must first establish the following parameters: State of Charge, battery capacity, and the desired Tesla electricity demand.

State Of Charge

The State of Charge is a measure of the battery’s health. For example, a Tesla owner’s usual range maybe 20% to 80%, which implies a depth of discharge of 20% and a charge limit goal of 80%. Of course, the State of Charge will vary based on each individual’s specific driving demands. A Tesla owner who drives 10 miles to work each day will have a significantly different charge requirement than a Tesla driver who travels 40 miles to work each day.

Battery Capacity

Tesla’s battery capacity is another important point to consider. Tesla’s Model X, for example, has a 100 kWh battery, whereas a kind of the Tesla Model 3 comes with a 50 to 70 kWh battery. Due to the capacity difference, meeting a State of Charge of 20% to 80% will require more energy for the Model X versus the Model 3 since it has a larger capacity. Although Tesla’s claim of “100 percent” charging efficiency may appear to be true, 100% is not the case. As previously stated, all lithium-ion batteries have an expected charging efficiency of less than 100%. This means that while a 75 kWh battery may be rated by Tesla. A driver may only get 90% effectiveness or 67.5 kWh of usable energy out of it.

Solar Panel Overview

A solar cell, also known as the photovoltaic cell, is a device that converts energy from the sun into electricity using an electrochemical process. Solar cells capture photons generated by the sun’s rays and transform them into electrical power through an electrolysis mechanism. When we charge lithium-ion batteries, we are able to store solar power as electrical energy. In this way, electricity generated by photovoltaic cells can be used to charge the Tesla battery. Owners of Teslas may use solar cells to collect solar energy and convert it into electricity, which can then be utilized to charge the car’s battery.

How Much Will It Cost To Charge The Tesla With Solar Panels?

For example, Barb’s new Tesla Model S has a 31 kWh per 109 MPGe capacity. We may calculate that if Barb drives 25 miles each day, her Tesla will burn 7.75 kWh each day (about 2,829 kWh per year). We can then apply our old annual energy production value of 303 kWh/year to calculate that Barb will need to add around 9 more solar panels to her system in order to fully cover her new Tesla and get the seal of zero-emissions approval.
