Still figuring out what to do for power.

Im trying to lower my electric cost from the grid.
130 buck in the winter and over 400 in the summer per month.

I have to get a 7 year return or quicker on the cost or its not worth it to me.
I have many neighbors with comerical solar installs and they are break even at best.

My ideas of what to do.

1. Complete stand alone solar powering separate sub panel.

2. Use a battery bank and use the grid to charge it off peak and power a seperate sub panel.

3. Or solar and batteries stand alone.
I would install secondary ac units off the sub panel

I think Ican do all of the above without a liscensed sparky.

4. Grid tie, i dont know what they will alow me to hook up and what they wont. Seems this is the easiest but the most expensive.

5. Install a sub panel and automatic transfer switch between the electric panel and the sub panel and be able to run the sub off the grid or diy electricity.

I feel exactly your pain since your e-bill is very similar to mine.

I'd advise you start by your power bills on one hand, and the different scenarios you envision on the other. At some point in time, one scenario will become less than your situation today and vs the other scenarios.

For our house, I have a 14kW backup diesel genset, therefore no need for batteries, so grid tie it is. You should also consider this scenario in my humble opinion as batteries easily double any setup.
