Tesla’s Solar Panel Woes And What Really Is Going On
The complaints about fires due to Teslas Solar panels have not been limited to just Walmart stores and Amazon Warehouses. Homeowners have also complained about Tesla Solar panels causing fires.
Henkes has reportedly been pushing Tesla to take action for years
Henkes was Teslas Solar field quality manager. He claims that a lawsuit on Tesla from November 2019 said the company had been aware of fires from the very beginning. It was said in this lawsuit that Tesla learned that aphemol H4 connectors were installed on the solar panels which may have caused the fires. According to the lawsuit, Teslas solar panels have been installed on 60,000 houses and 500 commercial and/or public buildings.
Henkes was fired from Tesla
Henkes was fired from Tesla. It is being widely reported that Henkes was fired because he exposed Teslas solar panel issues. It does seem that there is some validity to the idea that Tesla needs to improve their solar panels. Walmart sued Tesla over the solar panel issue.
Tesla has been under fire lately for other issues
They have had to face the NTSB which has been threatening Tesla with more regulations due to crashes that occurred. Tesla has also been accused by China of having cars that spy their military bases. Tesla was again accused by consumer reports of having cars that dont alert the driver, and then will spy on the driver. Many Tesla loyalists do not agree with how the media has been portraying Elon Musk and Tesla in recent weeks.
Tesla Solar Prices Decline To Near The National Average
Recently, Tesla announced a new price cut and philosophy in its solar panel business. Sanjay Shah, Teslas head of solar, said that the reason they were able to reduce pricing is in their new methodology, which includes standardized system prices and having homeowners photograph and upload images of their electric meters, breaker boxes, and other equipment to reduce the need for individual site visits. We spent hours and hours and days and days on the process, he said. It adds cost. It adds time. We needed to have a very streamlined process.

A Tesla Model 3 With A Solar Roof
Below is a neat video of a Tesla owner charging his Model 3 with the power of the sun. Cameron, who has the YouTube channel The Tech of Tech, shares exactly how he achieved this in his video.
I am charging my Tesla Model 3 from the power of the sun through solar panels that are on its roof, he said in the video. He later explained that the solar panels are not permanently attached to the vehicle. These are portable solar panels that I literally laid across the top. Each is 120 watts of power, Cameron explained.
The solar panels are made by Bluetti. The panels feed a 2 kWh power station acting as the go-between for the panels and the Model 3. Theres no way to get DC power from solar panels directly into the Model 3s battery, he said.
Cameron noted that this wasnt a cost-effective or an efficient setup but if anyone had the tools to set it up, its pretty simple to do. This is something that would be great for camping or use as a backup portable charger, one that would work when the sun is out. While charging his vehicle with the power of the sun, Cameron explained that he is doing his absolute best to reduce the amount of power, including turning off features such as Sentry Mode and everything except for the car itself.
Cameron explained that although Bluetti made the setup, the photovoltaics on the panels are from SunPower.

How Many Solar Panels To Charge A Tesla Powerwall 2
Tesla Powerwall 2 energy storage has a capacity of 14kWh. Lets assume that it is completely discharged and needs to be fully recharged with solar.
Using the average US irradiance value of 4 peak-sun-hours, then the calculation is as follows:
Solar energy required = 14000/4 = 3500 watts
Number of solar panels = 3500/300 = 11.66 panels, each 300 watts
Note: To take into account solar system losses, the power rating should be multiplied by 1.44. In this case, the number of solar panels required will be 17 panels, each rated at 300 watts.

How Many Solar Panels To Charge A Tesla Car
The answer to this question depends on the size of the battery in your Tesla, and how far you drive your car on an average day. A Tesla Model S, for example, has a 75 kWh battery, meaning youd need a whopping 75 kW of solar panels to charge your drained Tesla battery fully, every day.
In general, youd need around 3kW of power, or ten 300-watt solar panels to charge a Tesla car for daily use. Advertisements
On average, a Tesla car can drive for a mile on 100-watts of charging, with the daily average for most commuters being 30-miles per day. Naturally, if you drive further on average per day, youll need more power and thus more panels.
What Do You Need To Install A Solar Carport For Your Tesla Car
Let us say, for example, you drive an average of 50 miles each day. Then, by using the table above you will require 24 solar modules with 400 Watts capacity. Then, you will also need a steel carport structure to keep your solar panels in place. Here is the list of materials you will need to install this carport.
Is A Solar Roof On An Electric Car Something That Will Be Common In The Future
When the video above first came onto our radar, our first question was, “How well does it work?” We know that it’s possible to add some range to an EV via a solar roof, but not really enough to be worth the cost. Hopefully, as technology improves and costs come down, this will become more commonplace going forward, but it’s going to be a while.
This Tesla Model 3 owner didn’t permanently attach solar panels to the roof of his car. Instead, to see how it worked, he just laid them over the car. Obviously, this wouldn’t work for use while driving. However, if you’re going camping and your car will sit for a long period of time with no access to a charger, this might do the trick. It certainly can’t hurt.
A few cars are available with solar roofs, but they’re mostly a novelty rather than something useful. For example, when Hyundai completely redesigned the Sonata Hybrid for the 2020 model year, it added a solar roof as an option. It’s only on the top Limited trim, which costs about $8,000 more than the base model, and it can add about 2 miles of range per day.
Since the Sonata Hybrid isn’t a plug-in hybrid Hyundai eliminated the Sonata PHEV as part of the 2020 redesign the added range really just means saving some pocket change on fuel costs. With over 600 miles of range, the Sonata Hybrid doesn’t need the 2-mile bump.

Do Teslas Have Solar Panels
Solar panels and electric cars seem to go hand and handtheyre both better for the environment and it seems like solar panel technology would supplement all of the electric cars on the market today. So, do Teslas have solar panels then?
Currently, Teslas do not have solar panels on their roofs. Although Elon Musk has claimed their inefficiency, we may see them incorporated in the coming years.
Over the years, Teslas CEO has reportedly spoken out against using solar panels on electric cars. However, other electric car manufacturers have remained more optimistic.
Not only are solar panel-covered cars being developed by manufacturers like Toyota, but solar panel roofs are being used by other manufacturers to supplement auxiliary power needs. Tesla themselves might actually be closer than we think to roll out a Tesla with solar panels.
This is a very exciting space and sure to continue evolving over the coming years. Stay tuned.
Why Arent Solar Panels On Electric Cars
Solar panels arent found on electric cars because they are very inefficient. As stated above, one hour of being placed in the sunlight will only yield 3 miles of charge. Since the batteries and the motors are the main things that need power, a solar panel system placed on the car would not be able to support the amount of power needed.
Solar panels are also extremely expensive to make, and car manufacturers would not waste their most valuable resources, like money, on something that could be replaced by another charging option that is cheap. Having solar panels on the car would cost an extra $6,000, not including maintenance costs. When an electric car needs about 400 kWh a year, it would be a monumental task to get enough charge for your car every day.
Another reason that electric cars dont have solar panels is that there is not enough surface area on a car to catch the amount of sunlight needed to produce an efficient charge for the car to run on. The only place solar panels could be put on the car is the roof, and maybe the hood. There is not enough surface area to catch the sunlight, which means it cannot be converted into much energy.
Since solar panels are very inefficient, in many different ways, youd think those car companies would not want solar panels on their cars, but many continue to work on better results. Researchers are trying to make them more efficient so they can be better for the environment.

Own A Tesla Or Other Electric Vehicle Nice If You’re Interested In Charging It With Solar Here’s How To Calculate How Many Solar Panels You Need
Many electric vehicle owners also happen to be interested in solar electricity. That makes sense, because if youre an early adopter for either of these technologies, helping the environment was probably one of the factors in your buying decision.
If you have a Tesla now or youre planning to get one, you might want to know how many solar panels will you need to install on your house to charge it. In this article, youll learn that its not a straightforward answer, but depends on a few key factors:
This article will go into the details of this so that you can you make your own personalized calculation for your Telsa .
First off, lets start off by discussing the energy efficiency of a Tesla.
Can I Charge My Tesla Car With Solar Power
This question is very common among homeowners who bought electric vehicles. Yes, you can charge your Tesla car with solar panels. A Tesla car is a vehicle that does not require a drop of gasoline to operate. It uses electricity instead to power its electric motors that drive the cars wheels. Its electricity source is a pack of batteries that are placed safely inside this EV.
What is an electric vehicle, though?
An electric vehicle is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or maybe self-contained with a battery, solar panels, fuel cells, or an electric generator to convert fuel to electricity.

Tesla Solar Panels And Powerwall
A Powerwall needs at least ten 420-watt Tesla panels to charge it fully, and you can always add multiple Powerwalls if you require more power for your daily needs.
The Powerwall works just like any other battery storage option, although uses premium-quality lithium-ion batteries, and can handle very large power loads the system contains a 13.5 kW battery with 5kW continuous and 7kW peak capability.
Also, the Powerwall has an integrated smartphone app, allowing you to track and customize your power usage.
Does Tesla Manufacture Its Own Solar Cells
No, Tesla is not the manufacturer of its solar cells.
As noted above, until very recently, Tesla had a partnership with international electronics giant Panasonic to create Tesla solar panels. The partnership was based around using the highly-regarded Panasonic HIT cells to create Teslas solar panels.
With Panasonics departure from solar cell production for Tesla, it is not yet known what Teslas plan is to replace solar cell manufacturing. SolarReviews will monitor the situation for further detail as we are sure Teslas CEO Elon Musk has a plan in place.
Because of lower-than-expected demand for Tesla solar panels, Panasonic would produce solar cells in Teslas factory and then sell those cells to overseas customers. This turned out to be an unprofitable partnership for Panasonic, leading them to part ways with Tesla.

Home Ev Charging Options For Your Tesla:
A regular outlet will allow you to charge at roughly 4 miles per hour.
220v Outlet or EV Charger that will allow you to charge at roughly 20-35 miles per hour.
Homeowners who get an electric vehicle and charge at home will see an increase in their electricity bills. They are swapping the cost of paying at the pump to paying for higher electricity costs. A survey conducted by CleanTechnica of more than 2,000 EV drivers in 28 countries showed that 28-40% installed solar on their homes.
One Tesla S owner in Tustin, California, quickly found that charging his home was adding $75/month to his electricity bill. John, another homeowner in Huntington Beach, California, with a Tesla X and a Tesla Model 3, saw an increase of $125 / month on his electricity bill per month.
Both homeowners were considering solar for their home for quite some time. What finally allowed them to take the plunge was that they realized when it came down to selling their home, the solar panels would raise his homes resale value. On top of the generous federal incentives, solar panels can help increase your homes resale value. Plus, solar panels can improve the speed at which your home sells. They found that even with a solar energy lease, they could be saving more money on electricity costs than doing nothing.
How Many Solar Panels Does It Take To Charge A Tesla Overnight
Solar panels cant store electricity so a battery bank will be needed to charge at night. The size of the battery energy storage system can be calculated using the value of battery discharge in kWh.
In the case of a 60 mile commute for a Tesla S, this is 11kWh
Energy required = 11kWh/charging time = 11000/8 = 1375Ah
Number of batteries required = 1375/200 = 6.87 batteries each 200Ah
Cost of batteries approximately $3000
