Greetings,
I am buying my first solar system ever and I need some help in making sure what I order is going to be enough for the house. I also wanted some recommendations on solar panels. I'm looking for a panel that will last 15+ years in very cold weather and starts with 19% efficiency.
The items I am looking to use for my house are as follows. My highest load day ever is usually 12 kwh in the winter where I use electric to heat my home. The average days are around 7-9kwh.
My questions are
1) How much KWH would I need to go grid-less with my current needs based on few calculators I've used are 8kw of panels needed per day.
2) Do the items I am purchasing make sense or am I missing something below?
3) How many inverters can I use for a 8kwh system? The reason I'm thinking this inverter would be enough for whole house is I know the inverter can be smaller than total solar panel build. Please share your thoughts. Do I need two or one inverter?
4) Any recommendations on residential solar panels at the moment and where to buy them?
Thanks for the help. Again, just looking at if I'm over doing it for my very small house in Vermont. I oversized some due to sunlight issues and not optimal sun facing house.
Plan:
$8000 for two 12 KWH solar battery: https://bigbattery.com/products/48v-kong-lifepo4-233ah-12kwh/
$3000 for two all-in-one inverters https://watts247.com/product/lv6548...erter-4kw-250v-mppt-bms-ul1741-built-in-wifi/
Lastly, I'm looking for recommendation for a .50 cent per watt solar panel for this system. There's no limits on size or weight that the system can be.
