I hoping you can help me decide if I should go ahead with the SolarCity contract. I am aware that I will not be saving money, but I am willing to pay some extra amount to 1) be a part of the Tesla revolution and support the company, 2) have a backup for power outages (my alternative choice is a whole house generator) 3) generate some of my own energy
My house is in a very wooded area. I am willing to take down some trees (we have a ton of them and I need some firewood). The Tesla rep is proposing a 6.5kw system with an estimated production of 4,129 kWh (i guess that's yearly?) with usage offset of 25%. I may be able to up this with the removal of a few key trees.
The system cost is $37K with two powerwalls. I am getting two because I want to be able to power my house for an extended period of time if the power goes down. We have had a few multi-day outages in my area.
My average utility cost before solar is $231. My average energy cost after color they estimate at $422/mo. Hardly seems worth it. I am paying $200/mo for the system. I also get a $11,100 tax credit.
I could also go with one powerwall bringing down the cost of the system to $31,700. the monthly cost after solar will be $384 with a $9700 tax credit. This is much better, but how will I fair in an extended blackout?
My ultimate goal will be to offset my electricity, power my Model 3 when I can finally get my hot little hands on it, and have power in a blackout.
Does anyone know what I should be trying for with cutting down trees? What would be a good system size? How well will the powerwall be as a generator alternative (with me being in conservation mode during a power outage)? I am hoping I can generate power during the day to run the house at night (weather depending). I am worried that the wall will be empty after a day or so and I will be in trouble.
I am clearly new to all this. I do appreciate any advice you can give me.
