Tesla Powerwall: What Buyers Should Know?

When people hear Tesla, many of us automatically think of the innovative and easy on the eye cars. However, in 2015 Tesla stepped into the home energy storage sector and created a home battery product, the Tesla Powerall.

Tesla have always been at the front of the innovative game by introducing us to the incredible, self-driving automobiles. Their recent products in the home energy storage market leave us all in anticipation of how good they are going to be, as we are so used to Tesla consistently producing quality products. Below you can find out more information about their recent products and all the things a potential buyer needs to know about the Tesla Powerwall. Furthermore, you can find out more about the advantages and disadvantages of solar energy, find solar power comparison and compare solar quotes.

What is the Tesla Powerwall?

Like many people, we all thought that Tesla just made futuristic cars that we could all look at in awe. But now they have stepped into the home energy saving market and have set new goals for themselves as a company. Tesla described the Powerwall as a “rechargeable lithium-ion battery with liquid thermal control”, so in simple terms: it is a battery pack for home energy storage. Very few companies make small-scale batteries for home energy storage like this, it is a unique product that certainly has potential.

How Does Tesla Powerwall Work?

Tesla was originally looking at the battery life of their cars as electric car drivers had concerns. They were worried in case the electricity stored would run out during a journey and they would be stranded. Like any responsive company would do, Tesla researched the battery life more and discovered how their battery systems could be used in the home as well as in vehicles.

The Tesla battery pack is usually paired with a home solar panel system and has a unique way of storing excess energy from your solar panels. If you don’t already know about the advantages and disadvantages of solar power, take a look at some of the solar panel comparisons and compare solar panel deals to find the best one for you. As we know, the grid solar panel takes the excess energy and sends it back to the grid. The Tesla on the other hand stores the excess energy back into the battery pack instead of sending it away. At night, when your solar panels aren’t producing any energy the stored energy can then be used to power your appliances with electricity. An example of this would be, on a very hot summer day, your solar panels would be receiving a lot of energy from the sun, this, in turn, would supply the electricity in the house. However, with the best solar panel companies products, there would be more than you need. Later on, at night the house can still be powered thanks to the Tesla Powerwall and its stored energy.

Investing in Solar Panels

Before you invest in the Tesla Powerwall, it is important that you first do some solar power comparison research to see whether or not this is the right option for you. There are many advantages and disadvantages of solar energy and you should be fully aware of what these are as this is a costly investment. You will need to first of all work out your average energy output to determine how many solar panels that you will need for your home. It is also important when looking at solar panel deals that you won’t profit much from extra energy produced that is being transferred to a central solar grid. Take a look at solar panel reviews comparisons to try and find the best solar panels for you by comparing their quality, design, how much space they take up and also how much solar energy power they can generate. You can find accurate solar panel quotes online to give you a good idea of how much this is roughly going to cost you.

How Much Does the Tesla Powerwall Cost?

Looking to compare solar panel prices and the Tesla Powerwall? The Tesla Powerall 2.0 costs $5,900 and offers double the storage of the original Powerwall. However, it doesn’t stop there. An extra $700 will be added on for the equipment costs and then the installation fee can be anywhere between $2,000-$8,000. This why it is important to compare solar panels Australia and find the best solar energy quotes as you want to get the most value for your money.

If you are buying the Tesla Powerwall to link up with your solar panel system after receiving solar system quotes then it will depend on your systems wattage and how much you use. A 5kW solar system price Melbourne costs between $8,500-$16,000. This varies with the type of equipment you have and where your house is located. A potential buyer must consider the need for a product like this and the disadvantages of solar energy. You need to see if it would be worth the investment by finding out how much energy you use and solar energy quotes.

Where Can I Buy the Tesla Powerwall?

In 2015 there was a lot of hype over this product as people saw the capabilities in the product launch. However, after this, there were limited numbers on sale. The Tesla Powerwall was not on sale to the public until 2017 and after you have found the best quality solar panels in Australia and had them installed you can purchase the Tesla Powerwall online.

Installation

Tesla Powerwall 2.0 will ideally be stored beside the electricity metre. The main battery unit should be close to the gateway, if not the installation costs will increase. The best place for the Tesla Powerwall 2.0 to be installed would be in a garage with the metre and fuse board inside. Typically, it will take up to a day to install.

What Is the Warranty and Battery Life Like?

Unlike the 25 year warranty, we are used to with the best quality solar panels Australia, Tesla offer a 10 years warranty for the Powerwall. Like any chargeable product, the more you use and charge it the more unreliable the battery becomes. Compare your new iPhone battery with your old iPhone one and notice the difference and the toll the battery takes over the years. The Powerwall battery will deteriorate in the same way as your iPhone battery over time. This is definitely a factor to consider before purchasing. The Tesla Powerwall 2.0 has a 10-year safety net warranty therefore, it should last at least 10 years.

Price Increase

The first part of your Tesla Powerwall price investment would be $5,900. When first released it was $400 dollars cheaper, meaning it could be bought for $5,500. Experts believe that energy storage prices will fall as battery manufacturing increases. However, since the original price increase, Tesla has not increased the price anymore, but they could increase the Tesla Powerwall price in the future.

Mercedes Benz “Competition”

After witnessing the success of the Tesla Powerwall, automobile competitor Mercedes Benz decided to dip their toe into the home energy storage market. In 2015 Mercedes Benz introduced their version of the Powerwall, aimed to rival Tesla’s product. After designing the energy storing product, Mercedes Benz has decided to kill their own product. A Mercedes spokesman said “It’s not necessary to have a car battery at home: they don’t move, they don’t freeze. It’s overdesigned.” They believed the product was “over-engineered” and too expensive for the market.

Who Can Rival the Tesla Powerwall 2.0?

There are two home battery storing products that can potentially rival the Tesla Powerwall 2.0:

  • Sonnen eco
  • LG Chem RESU

Sonnen eco

The Sonnen eco is an energy storing battery from Germany which has been available in America since 2017. Similarly to the Tesla Powerwall, this is a lithium phosphate battery that is created for using the best quality solar panels. Sonnen has given the eco a self-learning software which can manage time of use electricity rates and can increase solar self-consumption for homes with solar panel systems.

Many people will be interested in the Sonnen eco because not only does it have a 10-year warranty (like the Tesla) it has a 70% capacity, meaning that the eco will maintain at least 70% of its storage capacity over the 10 years. This being said, it does have a smaller storage capacity than the Tesla Powerwall.

LG Chem RESU

LG have a product to rival both the Tesla Powerwall and the Sonnen eco called the LG Chem RESU. The RESU manufacturers are based in South Korea and is one of the more popular solar storage systems in Europe and Australia. Again, just like the other two, the RESU is a lithium-ion battery that comes in three different sizes. This also offers a 10-year warranty and has a 60% guaranteed capacity.

Capacity 13.5 kWh 4 kWh 3.3-9.8 kWh
Price $5,900 $9,950 $6,000-$7,000
Warranty 10 years 10 years 10 years
Guaranteed Capacity N/A 70% 60%
  Tesla Powerwall Sonnen eco LG Chem RESU

All three are very impressive products and each has their own unique selling points. The guaranteed capacity from the eco and the RESU do make them stand out from the Powerwall; however, the sheer size of the Powerwall capacity and price compared to the others edge out the competition that it faces.

Tesla Future Plans

Tesla have started to sell solar roof tiles to the public and not just the selected few. The solar roof tiles are an incredible design that makes the roof look like any other tiled roof, however, it has solar panels in it. The cost is high as it is $21.85 per square foot, however, Tesla believes that the solar roof will pay itself off in the future, it also has a lifetime of the house warranty and 30 year power generation guaranteed.

Summary

To summarise, Tesla are creating the future. They are taking normal ideas and making them extraordinary. From their self-driving cars to their solar panel tiles, they seem to be covering it all. This article has looked at the Tesla Powerwall, what it is, how it works, how much it is and many other aspects. I have also discussed the future plans and Tesla’s potential competitors. Tesla are creating for the future and it will not be long before other solar companies follow in their footsteps and start producing more innovative technology.
