Solar storage was previously a discussion about the distant future. But Elon Musk’s introduction of the Tesla Powerwall battery system transformed it into a discussion about the here and now.

Without a question, the Powerwall is an excellent home energy storage system. It has several amazing features and is reasonably affordable. Is it, however, the finest solar house battery to compliment your solar panels?

Latest news on the Tesla Powerwall

Tesla discontinued offering Powerwalls for private purchase in early April 2021. Instead, anyone interested in a Tesla Powerwall would have to additionally install a brand-new Tesla solar panel or solar roof system. That implies no retrofits for current solar systems, which is a real disappointment.

Tesla CEO Elon Musk later tweeted that all Tesla solar panels and solar roofs will include a Powerwall. As a result, when you buy solar panels from Tesla, you must also buy a Powerwall.

How much does the Powerwall cost in 2021?

The total cost of installing one Tesla Powerwall+ battery system in June 2021 is $10,500. The more Powerwalls you put up, the less expensive they become. This is due to the fact that the installation labor costs are spread over two batteries rather than just one, which reduces the overall cost. Remember that Tesla no longer sells Powerwalls separately. So the total cost will be a Powerwall plus a new solar panel system. Tesla no longer offers a breakdown of the Powerwall’s price; instead, they only disclose a total installation price.

Contrary to Tesla’s claim in September 2020, the price of the Tesla Powerwall will drop in half within three years. The Powerwall’s price went up twice since that announcement in September 2020, to its current price of $10,500. Fortunately, some areas offer battery rebates to help offset the installation costs, which is a welcome relief.

Not only can you benefit from the 26% federal tax credit, but some states and utilities also offer rebates and incentives. In certain circumstances, incentives such as California’s SGIP incentive and Vermont’s Green Mountain Power’s Bring Your Own Device Program can cover over 90 percent of the total cost of installing a Powerwall.

You may order a Powerwall directly from Tesla’s website or through a qualified Tesla installation.

Key features of the Powerwall

The Powerwall offers one of the highest useable capacity ratings of home solar batteries on the market, with a capacity of 13.5 kilowatt-hours (kWh). That is enough energy to cover almost half of the average US home’s daily energy consumption.

With the Tesla inverter and system controller pre-configured, the Tesla Powerwall+ installation is quicker and easier. Aside from the improved installation configuration, the Powerwall+’s power output is now slightly higher than industry norms. When connected to the grid, the Powerwall+ can supply 7.6 kW in daylight and 5.8 kW at night. This implies that the battery can power items like lights, outlets, and small 120-volt appliances.

However, depending on the conditions, the Powerwall+ may discharge additional power – between 7 kW and 9.6 kW – for off-grid applications. As a result, when your Powerwall is not linked to the grid, such as during a power outage, it can power a few additional appliances in your house. Output power varies from 10 kW to 22 kW when the sun shines on the updated Powerwall. The peak power capacity of a battery is the absolute highest amount of power it can provide in a very short period of time. When multiple appliances are turned on at the same time, or when the power goes out and then comes back on, the battery’s power capacity peaks.
