I am trying to size the right solar system for our home here in Hawaii. I do not want to invest in battery storage at this time and I plan to pay up front for the system vs leasing it. Our utility company requires a curtailment meter on the system if it produces more electricity than we use on a average basis. Since recently installing AC in the house our usage has gone up 30%.
So if we average 900 to 1000 monthly KWH we can go up to a 3.5kw system without needing curtailment according to their requirements. I got a bid for a 3.4kw 10 panel system and the price seems good and it gives us the option to expand the system and add a battery if we choose later on.
Of course I would love to just go for the full solar pkg with a Tesla battery and 20+ panels. But other repairs and upgrades to this home are in the works so I want to stay on budget. I am trying to keep the solar investment under $20k and the 3.4kw system is just the right price at around $17K.
Now after plunking in my info on pvwatts I am trying to decide if the small system is worth the savings we will get out of it. Pvwatts says it will produce on average 4500 to 4900kwh/year with a value of $1637.
I would appreciate anyone's opinion/advice.
