Tesla home solar systems
How do Tesla's solar systems compare to traditional solar panels?
Tesla has a unique ability to capture media attention and generate excitement about its products. This not only applies to their electric vehicles, but also to their solar roof and powerwall tiles.
- In contrast to a conventional solar module system, theTesla Solar Roofit has photovoltaic cellsbuilt into the shingles. There are no visible panels and many homeowners prefer this look.
- There are many home batteries on the market, but the Powerwall has some of the best specs, especially the new oneTeslaPowerwall+.
Considering a Tesla Solar Roof and Powerwall?
When trying to decide between traditional solar panels or a solar roof, each option has advantages and disadvantages. In any case, you can use household batteries, which means that your choice will not affect the availability of energy storage.
Read on and we willcompare both optionswith a simplified example. Accurate pricing is only possible with a professional home appraisal, but the numbers below can give you a general idea of what to expect.
Daniel's Tesla experience
In February 2021 we experienced the great winter storm here in Austin, Texas. We lost natural gas (heat) completely for a week, and water and electricity intermittently. Because it was 48F inside we had to leave our house for a week as we had a newborn son.
I decided I never wanted to experience that again, so I took a few steps to avoid it in the future. We got a 12 kW solar system from Tesla and 3 Powerwall batteries. From contacting Tesla to installation took 4 1/2 months.
We are now literally our own power factory and power outages are a thing of the past as our entire home is secured. Since our heating is based on natural gas, we now have some space heaters that our electric walls can just turn on when needed.
It is now early December 2021. Since our system start in early August we have been generating8,07 MWhwith our solar panels. In the same period, our house consumed only 6.48 MWh and we fed 1.23 MWh into the grid, which shows asCredits on our electricity bill. Some might say that we are literally helping to feed our neighbors and reap the financial benefits and peace of mind that there will be no more blackouts.
Update from Daniel, 11/30/2022:
“I have to say my Tesla solar panels and powerwalls are working beautifully! During these colder months, our electricity consumption is drastically reduced as our heating is with natural gas. With 3 Powerwalls, our 4,000 sf home gets through the night and we still have 50% reserve left that charges instantly with solar power at sunrise. The way I see it, powerwalls are insurance against power outages. It's especially reassuring to know that a power outage won't affect our ability to keep our homes warm. In fact, we don't even use the electricity grid in winter unless we have two or more cloudy days in a row!”

Daniels Tesla Solar Panels 2021
Traditional solar panels with energy storage system
As of 2021, you can expect to pay $3,000 per kilowatt of solar panel capacity, including other system components and their installation. You'll pay around $15,000 for a 5kW system and $30,000 for a 10kW system. Expect to spend around $10,000 to upgrade the system with a 10kWh home battery. When combining this battery with the 10kW solar array, the total price is around $40,000.
Thanks to the two-year extension of the26% federal tax credit, you can deduct $7,800 for the solar system and $2,600 for the battery. Please note, however, that only the battery is an issueif you ONLY charge it with the solar panels,and not with electricity from the grid. The potential tax credit that can be claimed is $10,400, bringing the net cost down to $29,600.
In April 2021, Tesla decided to bundle its products andyou can no longer buy them individually.
- This means you can buy a Tesla Solar Roof + Powerwall for your home or your regular solar panels + Powerwall. Unfortunately, Powerwalls can no longer be purchased individually.
- If you already have solar panels installed, your only option is to buy a different brand battery.
- But that's not a problem, because there are excellent alternatives, such as the 9.3 kWh LG Chem RESU and the 10 kWh sonnenCore.
Use of a Tesla Solar Roof and Powerwall
Since solar shingles also function as a roof, they are more expensive than solar panels. Unless your home has a very basic roof design, you can expect to pay upwards of $6,000 per kilowatt of power.
- From an economic point of view, this can make sense if you are building a new house or replacing a damaged roof. There are cases where you have to pay for a new roof anyway.
- On the other hand, if you want to maximize your ROI and don't plan on changing your roof, traditional solar panels make the most financial sense.
Assuming a price of $6,000 per kW, a 10kW Tesla solar roof would cost you around $60,000. Add the $10,500 Powerwall and the total cost of the project increased to $70,500. Compared to the previous example, this project is 76% more expensive for the same capacity.
Tesla offers a discount when purchasing multiple Powerwalls, which makes sense in larger homes with a higher project budget. A single unit costs $10,500, but the unit price goes down as you buy more:
- 2 Powerwalls for $17,000 ($8,500 each)
- 3 Powerwalls for $23,500 ($7,833 each)
- 4 Powerwalls for $30,000 ($7,500 each)
A Tesla solar roof gets that too26% federal tax credit, but cannot be deducted from the total price. Since you are paying for a new roof, all you can do is thinkComponents for solar generationby deducting the tax credit. The exact calculation depends on your roof construction, but the tax credit is comparable to a conventional solar system of similar capacity.
Instead of getting a $15,600 tax credit (26% of $60,000), the value is closer to the $7,800 we estimated in the example above. The Powerwall can get the full 26% ($2,730) as long as it only charges from the sunroof and not thenetwork. Using these assumptions, the tax credit is approximately $10,530 and the net cost is $59,970.
How is the Powerwall+ better than the regular Powerwall?
Tesla Powerwall and Powerwall+ have a usable storage capacity of 13.5 kW, a round-trip efficiency of 90% and a depth of discharge of 100%. However, the Powerwall+ has a higher power rating, which means it can power more devices simultaneously:
|continuous power||5 Kilowatt||In the web:7.6 kW Con Sol Pico, 5.8 kW Sin Sol|
From the web:9.6 kW Con Sol Pico, 7 kW Sin Sol
|The pinnacle of power||7 Kilowatt||From the web:22 kW Con Sol Pico, 10 kW Sin Sol|
The Powerwall+ has a built-in inverter, while the regular Powerwall requires an external one. The additional features of the Powerwall+ also make it heavier and slightly larger: the Powerwall+ weighs in at 343.9 lbs., while the regular Powerwall weighs 251.3 lbs. Both types of Powerwalls are smart devices, which means they can optimize their charging and power delivery to maximize your savings on your electricity bill.
The Tesla Solar Roof is an alternative to traditional solar panel installations as it combines photovoltaic cells and roof tiles in a single product. If you are not planning on re-roofing and want to maximize your financial gains, the best option is to use traditional solar panels.
If, on the other hand, you need a new roof for a new building or a major renovation, the Tesla solar roof combines ittwo installations in one. However, you should still get quotes for both options to make the best decision.
The Tesla Powerwall is one of the best home batteries available, but as of April 2021 it can only be purchased bundled with a Tesla Solar Roof or traditional solar panels. If you are looking to add a battery to an existing solar system, consider other leading battery brands such asLGÖSonne.
