PV Grid-tied System options
I'm new to this forum and seeking advise on adding a PV system to my house. Actually, I have too many questions but the main question I have is if I should proceed with this project since it does cost a good amount to get started. The basics first: I have a 13 yo home that is well built - 2,800 sq ft living with about 3,800 total area. My bills run between $250 to $450 per month. Cost of power is currently 16.1 cents per kwh. In July i used 2,900 kwh. Live in south Texas (lots of sun).
Can I get a decent invertor like the Xantrex 3.8 GT and connect only about 4 panels of 120 to 200 watts each to get started? Later, as budget permits I would like to add more panels - like 4 at a time.
Thanks in advance for any advise. I do appreciate it.
