Tesla Solar Battery Flaws & Alternatives

The Tesla Powerwall, a lithium-ion battery, has been in the news lately and has gained the interest of California homeowners. Likely due to the brand awareness that comes with its name, many folks who are interested in home energy storage systems have tried the Tesla solar battery in recent years.

The Powerwall has garnered its fair share of purchases, and has also left many unsatisfied buyers wondering, “Could I have gotten better value elsewhere?”

As experts in this industry, we’re here to give you our honest assessment of the flaws associated with Tesla solar batteries and recommend an alternative product that meets the mark without compromising on price or quality.

The Cons of The Tesla Powerwall

As with any major purchase, having all of the facts is an important step all buyers must take before making the leap to solar. While the Powerwall has great press surrounding it, there are certain drawbacks that many remorseful customers admit to having overlooked when they chose to go with Tesla over its competitors. 

We’re here to dive into the three core flaws we’ve identified in Tesla’s solar battery so that inquisitive dealers or homeowners can make informed decisions about their solar energy storage solution. 

In the world of cutting-edge home energy solutions here’s where Tesla falls short:

High Installation Costs

While the Powerwall itself boasts a reasonable price tag at first glance, many homeowners don’t take into account the installation costs associated with its purchase. On its own, a Powerwall costs about $9,200. However, since buyers are required to use a Tesla Certified professional to install it, that price tag jumps up by 25% to $11,500. 

Even with tax credits, there are certainly more cost-effective options out there. If you’re thinking about adopting Tesla’s solar battery, you should be prepared for the potential financial implications beyond your initial purchase. 

Need For Multiple Units

If you’re looking to live off-grid or totally energy independent, the Tesla Powerwall likely isn’t the right choice for your needs. In truth, for you to do something like that, you would need multiple Tesla solar battery units, as just one likely won’t have the capacity to power your home past the bare essentials. 

That means shelling out another $11,500 on top of the last $11,500 that you spent just to have enough power to live your regular lifestyle without interruption. As we’ll go into, there are plenty of one-and-done alternatives that easily alleviate this issue. 

Poor Customer Service

Especially as of late, a lot of negative feedback has surfaced regarding the Powerwall and its customer service team. These communication issues highlight a consistent theme with Tesla solar battery products – it’s difficult to get help when you actually need it. This has been going on for years too. 

In fact, a 2021 article by Business Insider highlighted this exact issue, even going so far as to say that Tesla has left calls and emails from some customers unanswered for months on end. And the popular brand has not yet found a solution for their customers’ dissolution.

Alternative To The Tesla Powerwall

As we’ve detailed above, Tesla’s Powerwall falls short in three main categories: cost, capacity, and customer service. At NeoVolta, we believe there’s a better way to run on solar. The NV14 is our alternative to the Tesla Powerwall that will set your power consumption projects apart:

More About the NV14

NeoVolta’s NV14 has your back. Our namesake solar battery stands tall where the Powerwall falls short. See for yourself:


Compared to Tesla’s price tag after installations, the NV14 comes in at a similar price but packs much more of a value. While the total cost depends on your solar configuration, the NV14’s cost generally falls below the median residential storage cost, and its performance is hard to beat. That means if you have the budget to purchase a Powerwall, you can certainly buy a superior product in the NV14 without worrying about whether or not your purchase was worth the price. 


When it comes to capacity, our battery can provide up to 32 amps of continuous, always-on power to bypass peak rates or grid outages, compared to Tesla’s 21 amps, which requires homeowners to stack multiple units in order to get more amperage. With the NV14, homeowners no longer need to worry about an insufficient energy supply. Our innovative battery storage system keeps energy ready and available for use for a longer period of time, resulting in electricity savings, and increased energy independence.

Customer Service 

And finally, we have customer service. At NeoVolta, we take our clients seriously, and are committed to helping them find the solutions they’ve been looking for in a timely, convenient manner.
