Battery Day & Tesla's Shareholder Meeting tentatively scheduled for Sept. 15th

Tesla’s Shareholder Meeting usually takes place in June but, due to the global pandemic, Elon Musk just recently shared on Twitter that it has tentatively been pushed to September 15th. And as a bonus surprise, it will be the same day as Battery Day. My question- which I asked on Twitter but hasn’t received and answer yet- is if by owning Tesla stock you’d be allowed to attend both. That’d be super cool!

Everything you need to know about version 3 of Tesla’s new Solar Glass Roof Tiles

Last Friday - October 25 - Tesla presented the third version of its solar roof. Kyle Field did this nice write-up about it, here are my highlights:

  • The price of the Solar Glass Roof is less than a new roof plus solar panels. It doesn’t make sense to get it if you don’t need a new roof but if you do, consider this option
  • With this version, Tesla has dramatically reduced the number of parts and sub-assemblies by more than half
  • Power output and weatherization are covered for 25 years
  • Tesla has two teams competing with each other trying to find the best possible way of installing it. Elon was saying that Tesla is targeting to lower the installation time to eight hours, imagine leaving in the morning and coming back from work to a brand new Solar Glass Roof

First electric bill post-Tesla solar/Powerwall installation

A Reddit user shared their first electric bill after installing solar panels and Powerwalls. The cost of the system was $30k and in the first month, the bill went from $692 to $110. Even not sustaining these savings year-round, they should be able to pay back the system in under ten years!

Get your Powerwall referral credit

If you have the Powerwall referral reward and haven’t used it yet or you don’t know what to do with it because getting a Powerwall is not in your plans, it seems like Tesla is offering $5,500 of credit instead. This credit can be used towards service, vehicle accessories, as well as new Tesla vehicles.

In order to do so, reach out to Tesla ([email protected]) and Tesla energy, and they should be able to take care of it.

Overall, the largest system is still the same price as before the latest update when combining Solar and Powerwall.

Tesla cuts prices of solar systems to counter drop in federal rebate

On January 1st the tax credit for residential solar systems went from 30% of the solar system cost to 26%. Cleantechnica reports «Tesla responded to the smaller federal incentive by slashing prices across its four options — small, medium, large, and extra-large out-of-the-box solar systems. For example, the after-rebate price of Tesla’s small 3.8 kW solar panel system was slashed from $8,342 to $7,770, a 6.9% drop compared to the price of the system just last week.»

Remember that next year the federal rebate will go down to 22% and it will go away in 2022. If you are purchasing a new solar system from Tesla you can use our referral code to get $250 off the price http://ts.la/ignacio9266

Tesla issued a 'storm watch' alert ahead of PG&E's planned power cutoffs

Storm Watch is the alert that Tesla issues every time that some areas might lose power (e.g. because of a hurricane). If Storm Watch is activated, all the Powerwalls in that area immediately start charging to full using the grid so they can be ready to back up the house. In the US, during normal operations, Powerwalls connected to a solar installation can’t take energy from the grid. During normal circumstances, they are only allowed to charge from solar.
