The secret is out.

Tesla, the California based Electric vehicle and high technology company lead by the “future tech entrepreneur” Elon Musk, is making final plans to release a second generation Powerwall—its home energy storage system—this summer of 2016.

The tech website Electrek reports that Elon Musk made this breaking announcement during an exclusive event for Tesla owners in Paris this past week.

“We are coming up with the version 2 of the Powerwall probably around July or August of this year, which will see further step changes in capabilities.”

Talk of a cliffhanger.

The report adds that he didn’t reveal much but his choice words (“step change”) suggests that this update would not simply be an aesthetic fix but a complete technology upgrade to the current storage system.

Last year, we all remember that the first generation Tesla Powerwall sold out in less than a week. The system racked up over 38,000 pre-orders at $3500 for a 10kWh system and $3000 for a 7kWh system. Maybe this second version will beat the record.

Lets review the specs of the current Powerwall:

Each Powerwall has a 7 kWh energy storage capacity, sufficient to power most homes during the evening using electricity generated by solar panels during the day. Multiple batteries may be installed together for homes with greater energy needs. A 10 kWh weekly cycle version is available for backup applications.
