Is The Powerwall Worth It

The Tesla Powerwall isn’t cheap, and whether or not it’s worth it depends on how you currently power your home. However, if you have solar panels or are about to buy them, the Powerwall is well worth considering. It’s competitively priced, well-designed, and from a reputable company.

If you don’t have solar panels, or you are buying them in the hope of lower energy bills, it’s important to calculate the savings before you buy one. A Powerwall will save some people money, but how much depends on the difference in rates between the day and night.

The reliability of your electrical grid is also worth considering. If you live in an area with regular power outages, you might find the cost of a Powerwall is worth it, even if it doesn’t save you money.

What Is A Powerwall

The Tesla Powerwall 2 is a rechargeable lithium-ion battery storage system, primarily designed to be used with a solar PV system. It stores excess electricity which can then be used when the sun isn’t shining i.e. overnight or on days with poor weather. This stored electricity can then be used to power the building once the sun has gone down, when there is poor weather or even during power cuts .

The Tesla Powerwall 2 can be used in virtually any building with a solar PV system, whether that’s a home, a commercial or a public building. It works best when there is plenty of excess day-time solar electricity that would otherwise be exported back to the grid.

The previous generation of this system was called the Tesla Powerwall, which had a smaller battery capacity and fewer features. Details of a forthcoming Powerwall 3 are yet to be announced by Tesla.

Do Solar Panels Increase Home Value

Yes! According to market research, solar installations increase home value by 3-4% depending on the size of the installation. This depends on your location, though, as the increase of value can vary widely depending on location, even where the same setup is installed.

In general, solar panels increase home value by $6,000 per kilowatt installed.

How Long Does It Take For Solar Panels To Pay For Themselves

Does The Tesla Solar Roof Make Sense? PowerScout Does The Numbers ...

The short answer is about 6-10 years. However, a lot of factors go into calculating the point at which you will break even for the cost of the solar installation.

  • Price of the system This is the price of the solar panels , along with necessary hardware, installation, etc. This amount will depend primarily on the capacity of the solar installation, but also on your location and the solar company you choose.
  • Incentives and rebates These can be in the form of federal, state, or local rebates, tax credits, etc.
  • Electricity usage The more electricity you use, the bigger the system you will need to offset the costs. At the same time, higher usage will ultimately create more opportunity to save money, and this means less time that it will take for you to break even on your solar investment.
  • Electricity generation Ideally, you want a system that matches your usage as closely as possible. If you buy too big a system, it will generate far more solar electricity than you can use. You will pay more for a bigger installation, only to waste a large part of what you are producing. With all this waste, it will take a lot longer for those solar panels to pay for themselves. On the other hand, if your system isnt big enough, you are not saving all the money you could. Your initial investment will be lower, but the system wont be able to generate enough solar electricity to make much of a difference.

How Good Are Tesla Solar Panels

Tesla currently installs Hanwha Q CELLS Peak Duo Black solar panels more specifically, the Q.Peak Duo Blk-G6+ modules which are not exclusive to Tesla.

This specific model has an up to 19.5% efficiency rating a pretty average figure, which doesnt quite match some of the best solar panels on the market, which have efficiency ratings of around 22%.

However, if youre searching for aesthetically pleasing panels, Hanwha might be the way to go. The panels sleek black body has no visible gridlines, and its concealed edges make it blend into the roof nicely.

Plus, Teslas mounting hardware uses 30% fewer anchor points on the roof, compared to a traditional installation, making the solar panels less prominent.

An additional feature that many solar panel owners will find useful is Teslas smart solar inverter, which has Wi-Fi and cellular connectivity. This means it can easily integrate with Tesla Powerwall and the Tesla app, and users can manage their solar system from anywhere in the world.

Final Word On The Tesla Solar Panels

If you are a Tesla fan, Tesla solar panels are a great choice and can easily be installed with a Tesla Powerwall home battery for a completely renewable house. But, Tesla solar panels are not the best option in the market in terms of panel efficiency.

SolarReviews recommends these brands if you choose to shop for solar panels based on efficiency.

Shop around and use our solar calculator to get a few competitive quotes before choosing a company and solar panel brand. After comparing costs, perhaps take advantage of Teslas price matching option if Tesla is your brand of choice.

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.

Tesla Unveils Latest Version Of Solar Roof While Dodging Big Questions

NEW Tesla âProject Dojoâ Will Make Them BILLIONS!

In a significant strategic shift, Tesla will begin working with outside roofing companies.

Staff Writer Greentech Media

Any type of solar roof tile you want, as long as it’s tempered glass.

Three years in, Tesla is beginning to publicly acknowledge the difficulties involved in creating and scaling a solar roof tile.

The electric car company turned clean energy provider has tended to downplay or ignore the long history of failures and disappointments in the solar roof industry. In October 2016, Tesla pitched the tiles as an aethetically stunning tool for a renewably powered future.

CEO Elon Musk is still envisioning a better future, but he’s now sharing more of the shortcomings Tesla has encountered in its product development so far. That started with revealing, in a quarterly earnings call this week, that the first two versions of the solar roof were not ready for the big time.

He promised to reveal the third generation the following afternoon. On the following afternoon, he tweeted that the unveiling would take place the next day at 2 p.m. “California time.” The next day, at 2:30 Pacific, Musk followed through on his promise.

The third version of the solar roof reflected continued refinements rather than a clear transformation from the previous versions, which were never widely released.

Other aspects of the new product still remain fuzzy.

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.

What to Teslas new prices look like? Check out our table below to see what solar energy systems offered by Tesla will cost:

How Much Is The Tesla Powerwall

The Tesla Powerwall costs $10,500 when purchased directly from Tesla. If you need more than one, the price goes down with quantity. You can currently purchase two Powerwalls for $17,000. If you’re not purchasing solar panels, you will need to find an independent retailer, and prices vary.

It’s important to note that while the price above includes installation, it doesn’t include any necessary adjustments to your home. For example, if your electrical panel isn’t compatible, you may be required to pay an additional fee to replace it.

Provided you’re using the Powerwall with solar power, you may be able to get a federal tax credit of 26%. This can make the Powerwall more affordable but it’s only applicable if the Powerwall gets 100% of its charge from solar panels.

Depending on the state in which you live, additional rebates may also be available.

Who Should Buy A Solar Roof

How Much Does A Tesla Solarglass Roof Cost

The initial appeal of the Tesla Solar Roof will target the wealthy, tech-savvy homeowner with a passion for renewable energy. Due to the solar roof cost, the purchaser of a solar roof will have a deep passion for aesthetics.

There is certainly a risk-reward aspect of being one of the first owners of a Tesla Solar Roof. The reward is obviously being able to be one of the first owners of this beautiful technology. The risk is the same. Being the owner of the first version of anything comes with the risk of having to be patient while kinks are worked out.

If you want to be an owner of the Tesla Solar Roof you will need a large amount of expendable cash and an even larger amount of patience as it could take years for the solar roofs to get installed.

Solar Roof Vs Solar Panels

There are two major differences between a solar roof and a traditional solar panel system complexity and price.

Talk with any roofer or solar company that has worked with the solar shingle product, well bet theyll tell you that the Tesla solar roof is one of the most complex and intricate roofing systems that they have ever seen. An average 8kw solar roof will have around 460 solar shingles, which means there are 460 wiring connection points on your roof . On the other hand, a traditional solar system for this size will include around 25 solar panels, meaning 25 connections.

With a traditional solar system, you can also get panel level solar monitoring so you would know exactly when a panel is underperforming while being able to pinpoint exactly where the problem is in your system. This level of monitoring just isnt available yet for the solar roof, making it a challenge to quickly address any issues when they come up.

Next on the list is price. Teslas Solar Roof website has a slick calculator that takes your address and uses Googles Project Sunroof to automatically generate a Solar Roof solution for your home. While the tool is fun to play with, the prices and energy savings it estimates dont impress us when compared to traditional solar panels. Lets take a deeper dive into price differences between the Tesla Solar roof and traditional solar panels.

Pros Of Tesla Roof Tiles

Design: The most noticeable difference between solar panels and the Solar Roof is design. Tesla offers four different styles to choose from textured, smooth, Tuscan, or slate styled solar roof tiles. The tiles mimic the look of a traditional roof so your neighbors wont even know you have solar on your house . If you want to maintain the aesthetics of your rooftop, the Solar Roof tiles are a great option for adding solar energy to your home.

Warranty and durability: Tesla roof tiles are made with tempered glass that is more durable than standard roofing tiles. Tesla stands behind the durability of their product with an infinite warranty . We dont know the full details of their warranty, but thats quite a bold offer.

How To Calculate How Many Solar Panels You Need To Run Your House

The number of solar panels you need to run your house depends on several factors, with the most important being your energy needs. You may have a big house but with very few appliances that require electricity.

This means you might not need a large number of solar panels. Conversely, you may have a small house but your energy requirements are high, meaning you need many solar panels to meet your energy usage.

A typical home requires between 20 and 25 panes to offset electricity usage. If you want to calculate the exact number of solar panels you must consider the following factors:

  • Panel rated power
  • Energy consumption habits

Heres a breakdown on how to do the math:

The average annual electricity usage in America is 10,649 kWh while solar panel wattage averages at 320 watts.

Production ratio, which is the energy output of a system in kWh ranges from 1.3 to 1.6. Heres the formula used to estimate the number of solar panels required

Annual electricity usage average/ production ratio / panel wattage

10,649 kW /1.3 kWh /320 W = 25.6 solar panels

Does Tesla Manufacture Solar Tiles

As well as traditional solar panels, Tesla also supplies solar tiles, which blend into your roof seamlessly.

Whilst the Tesla website insists that the company creates solar tiles in its factory in Buffalo, New York, there has been a lot of scepticism around this claim. In fact, in a bid to figure out how accurate this claim is, PV Magazine looked into the tiles origins and found that they were shipped from China.

How Much Does The Tesla Solar Roof Cost

With the new complexity categories explained above, its a bit difficult to fully estimate the cost of a Tesla Solar Roof. The cost varies significantly depending on whether your roof is simple or complex and depending on the square footage of your roof. If you have a fairly small and not too complex roof that you already need to replace, the price of a Solar Roof will probably be fairly comparable to that of a new asphalt roof installation plus solar panels. However, as you increase the size and/or complexity of your roof, you can expect this number quickly skyrocket.

For an 8.18 kilowatt system in California, Tesla estimates that the solar roof will cost $45,300 before incentives if you have a 2,000 square foot roof. However, Tesla estimates that you could spend up to $16,095 more on your Solar Roof, depending on your roofs complexity. Additionally, if your roof is 2,500 square feet instead of 2,000 square feet, the price jumps to $53,000. You can dig further into these calculations in our comparison of the cost of the solar roof vs. standard panels.
