This Is The Way Tesla Power Walls Work

Recent reports suggest that the cost of renewable energy sources such as wind power or a solar installation has fallen below the cost of traditional energy sources such as coal. However, one of the biggest problems with harnessing solar power is storage. The solar cells can only produce electricity during the daytime and that power needs to be stored somewhere in order for it to be used in times of need.

This is where the Tesla Power Wall comes in. You must have heard of Tesla, the electric car company. It is the company that is spearheading the race for electric vehicles and it is the biggest electric vehicle maker in the world today. In 2015, the company announced Tesla Power Wall which is a battery for the home.

In simple terms, it is a rechargeable lithium ion battery similar to the batteries you have in your mobile phones that can be recharged hundreds of times. This rechargeable lithium ion battery can be hooked up to solar panels or the electric grid in order to be charged. In other words, think of the Tesla power wall battery as a huge mobile phone battery that hangs off the wall.

Once the battery is fully charged, it is capable of feeding the energy back into the electric grid in case there is an excess or just store the energy in order for you to use it at a later date. Currently, the battery is available in two variants, 7 kWh and 10 kWh.

For a regular home, the 7 kWh battery should suffice. The company claims that it will charge during off-peak hours and the stored energy can be consumed during peak hours. The bigger battery is aimed at bigger homes as well as businesses. In case you have a bigger requirement, you can always buy multiple batteries and hook them up together in order to meet your needs.

The company claims to have sold thousands of these units to homeowners all around the world. As far as the cost is concerned, you will need to check online in order to figure out the cost of this battery in your location. You will also need to pay for the installation of the battery and that will add to the cost. In order to calculate whether investing in this battery makes financial sense for you, you will need to calculate the cost of energy in your location and then compare it with the savings you will make by investing in this rechargeable lithium ion battery.

One of the biggest advantages of this particular battery is that this is guaranteed by the company for 10 years which means you won’t need to replace the battery for a period of at least 10 years. Therefore, when you are calculating your costs, you need to take into account the fact that you are making an investment for 10 years. Most estimates available online suggest that owners should be able to breakeven in around five years. However, your breakeven point will depend on the cost of energy in your area.

There are also some concerns by prospective buyers whether this battery pack will look good in their home. It is a very well-designed unit that just hangs off the wall and looks great. So, you do not need to worry about the looks of this battery packs.

Overall, the Tesla power wall batteries work like just any other battery. The biggest difference is that these batteries are guaranteed for a period of 10 years which makes them financially viable for most households and hopefully, spark a rise in the number of solar power installations.

Tesla Power Batteries

Despite having fewer rebates and lesser feed-in tariffs than previously, much more households are setting up solar power systems to cut back power bills and make their houses more eco-friendly.

In other interesting information for potential – and present – solar panel-owners, the release of Tesla’s Powerwall home battery implies homes can get a lot more from their solar power systems.

What’s the Tesla Powerwall?

Tesla talks about the Powerwall as a “rechargeable lithium ion battery with liquid thermal control.” It’s among the few firms in the household energy storage market which makes small-scale batteries for house energy storage. The first-generation Powerwall released in April 2015, and an upgraded Powerwall 2.0 was introduced around October 2016. The cost of a Powerwall 2.0 battery (excluding installing expenses) is $5,500.

Tesla battery packs are a perfect pairing for solar panel systems, particularly in the event of off-grid projects in which homeowners require or wish to become completely independent of their power. The solar storage option such as the Tesla Powerwall enables you to sustain a power supply in the daytime or night.

One big constraint of solar photovoltaic (PV) systems is they do not produce electricity in the evening (naturally!) thus they are still dependent upon connection to the grid for night-time power and when the solar array or inverter breaks down for whatever reason. However the Tesla home battery could store the solar-generated electrical power to be used later.

The idea of a home battery storage system is not new; they have been around for a long time, like those coming from Solar Australia. Some other electrical power storage systems (battery as well as other technologies) are made for large-scale industrial or commercial use. However Powerwall might be a game-changer for the electricity sector.

How much it cost?

The list cost to get a new Tesla Powerwall 2.0 battery, that provides two times the storage capacity of an original Powerwall, is $5,500. Supporting components gives one more $700 to the equipment expenses, which gives the sum of $6,200. Installation can also add from around $2,000 to $8,000 to the overall bill.

It’s important to remember that the list costs you see do not cover the expense of installing your Powerwall in your property. Tesla quotes that particular installation will put $800 to $2,000 into your bill. Then again, this estimate does not cover the expense of electrical upgrades, permit fees, taxes, or connection costs. EnergySage customers have claimed installation expenses which add anywhere from around $5,000 to $8,000 (prior to any financial incentives are applied). The total number will be primarily based on the particulars of your installation.

If you wish to install the Powerwall as part of the solar-plus-storage system, battery expenses are simply one portion of the equation. A typical 5 kilowatt (kW) solar energy system rates anywhere from around $8,500 to $16,000 depending upon your geographical area and the kind of equipment you select. That might appear to be a lot of cash, however installing a solar-plus-storage system could be a worthwhile expense.

Why is Tesla’s home battery different from others?

Compared to other Tesla technology, Powerwall is open patent, that will enable competitors to create the same or even much better products. Thus even though Powerwall isn’t the first such system to show up, this could be the one which makes battery storage systems a standard feature in houses.

For an average house, Powerwall and a solar array altogether can turn into the primary source of power, having the grid connection serving just as a back-up and top-up for extended periods of low sunshine. Nevertheless, the system can also let total self-sufficiency for a few houses.
