The Powerwall is a home battery developed by Tesla. The price of a Powerwall can vary depending on several factors, such as the country you are in, possible subsidies or tax benefits, installation costs, and the selected configuration. It is important to note that prices can change over time, so it is best to obtain the most recent information directly from Tesla or from authorized dealers.

For reference, in September 2021, the Powerwall had a price of approximately €9,600 in the Netherlands, excluding VAT and installation costs. However, please note that this is only an indicative price and the final price may vary based on different factors.

To get accurate and up-to-date information on the price of a Powerwall in your specific situation, I recommend contacting Tesla or an authorized dealer near you. They can provide you with the most recent price information and help you determine the total cost of the Powerwall installation.
