Installation cost difference for PW-2 through a licensed installer vs. TSLA

edited November -1 in Energy Products
I am having a really hard time getting Tesla to engage / respond and act upon our request to get a PW-2 installed (with existing solar).
I am wondering if I should go down the route of working with a local licensed installer to get PW-2.

Do you know what a typical $$ difference would be between TSLA installing the PW-2 vs. a licensed installer?
Any experience or anecdotal evidence?

we're in North CA. 4KW existing solar. PGE utility. Looking for 1 PW-2 installation.

    Should not be much difference in pricing. Suggest calling a few authorized PW dealers in your area for quotes.
  • You may be unaware of the SGIP rebate program for folk who install storage batteries. Tesla, I understand, has exhausted their “allocation” of SGIP rebates. Yes, they are for installers to pass along. It can be pretty substantial, I.e., 35-45% of purchase price. Contact other installers in your area & go with them if they still have the rebate to offer you. BTW is 1 PW enough, given that you’re a PGE customer, as are we. We installed 2 and should have installed 3.

    Certified Installers take advantage that you could still get SGIP thru them and "adjust" price accordingly. That being said, you should talk to all certified installers in your area. I found quite some price differences between them for the same job. Also, if you get 2 PWs, the overall cost is higher, but price per kWh stored is lower.

    @david_gelfand and @m3noice,
    Thanks for your input. I thought of getting more than 1 PW, but wasn't sure if a 4KW solar array will be sufficient to charge the 2 PW setup.

    It depends, summer time will produce more than winter.
    In average, a 4kW system will produce ~6,000 kWh per year.
    That’s an average of ~16 kWh per day... So, in average, two batteries is too much for a 4kW system...

    However, two batteries will allow you to backup the whole house due to a maximum output of 10 kW instead of only 5 kW for a single battery... it’s your call!

    Agree with Passion - two PWs will provide a lot more continuous power, backup energy, and use case flexibility - even with a small generator. On a previous thread we were comparing notes and discussing the use of 1 Powerwall for every 5 kW of generation capacity as a good general rule-of-thumb. More units are usually OK s if one is looking for more backup reserve capacity.

    I had my PWs installed by Tesla. Having a hard time getting Tesla to engage is a warning that you should heed. Tesla Energy customer service is not good. I recommend you go 3rd party. My anecdotal evidence is that the earliest appointment offered with a technician to look at my inoperable PWs is over four weeks away.
