Final thoughts

Tesla pioneered domestic Energy Storage Solutions (ESS) with the Powerwall. Since then, dozens of companies offering competitive products have popped up.

Indeed, we are now living through a transitional phase when it comes to energy production — from fossil fuels to renewables. Moreover, we are moving from a centralized to a decentralized way of producing energy.

Thanks to the combination of solar panels and ESS, anyone can become a producer of electricity that can be self-consumed or despatched into the electrical grid.

ESS systems are becoming more affordable with the dropping price of LFP batteries. In addition, with the development of hydrogen technologies, their energy density and reliability will improve, making them an essential addition to every household in the coming years.

Really good informative article. We are a solar and wind company out of Cheyenne, Wyoming. We are often researching new products- this article was great, I sent it out to my crew and we will be discussing all these ESS alternatives to Tesla. Thanks again!

Kyle Browning

Hi Kevin, we are glad you enjoyed the article! :)

Paul Meagher

the equipment cost of a Powerwall is USD 7.5K plus an additional $1K of required equipment


If I already have AC panels via Enphase microinverters, I suppose I lose efficiency having to reconvert AC to DC for storage. Then convert again to AC for domestic use, right? A full extra round trip DC(panels)-AC(microinverters)-DC(MPPT)-AC(final inverter).

Kyle Browning

Hello Crevasse, yes that is correct. Naturally, you will lose efficiency when converting AC to DC, likewise from DC to AC again. The amount though depends on the equipment you are using.

Steven Wonder

Can any of these be set up to deal with a brownout condition? In other words provide that percentage of electricity that the local utility company is reducing to a home due to high demand? Thanks.

Kyle Browning

That is the purpose of energy storage systems such as the Tesla Powerwall and its alternatives.

People buy batteries for two main reasons:
1. They want to use solar energy later in the day when the sun is not available.
2. They want a source of backup electricity during emergencies such as brownouts/blackouts/”clouding” (when clouds block the sunlight)

That is why a lot of people consider hybrid solar systems.

Note: A Hybrid solar system combines the concept of both grid-tie and off-grid systems; it’s a grid-tied type setup with the added energy storage component for backup purposes.

In your case, it’s difficult to estimate how much electricity your utility will ration to your home each time a brownout occurs. Therefore, people typically get an energy storage system (ESS) that can support their essential appliances during a blackout (no power coming from the utility).


we have a Tesla Solar Roof… are all of these options compatible with it?

Kyle Browning

In principle, all solar panels should be compatible with any battery. However this should be done with caution. If you are going to handpick brands instead of availing bundles, you should be prepared to DIY.

Also, I have second thoughts about LAVO ESS since it is a hydrogen battery technology. You might need a special inverter for this.

Practically speaking, tesla is selling their solar panels as a bundle with powerwalls. You can choose to buy Tesla panels and pair it with other ESS but this will hurt your long-term relationship with your installer/service provider.

Most times it is better to avail the most cost-effective bundle in the solar plus storage market.


Interesting article, thanks. I’m wondering if an ESS system can reduce energy costs by letting it charge from the grid during the night (low price) and using the battery during peak hours (high prices) – so without solar panels. How big a price difference would you need to make it financially viable? how big a loss is there in charging an home battery? Here in Denmark electricity prices are fluctuating enormously, so I hope you can give some indications. :)


Romaine, you failed to mention that the Tesla Powerwall+ has an integrated 7.6kW PV inverter, and that the Powerwall can scale to 10 units, which is 135 kWh.
