When the OP suggests he wants less dependence on the grid...if this is grid tied will it work if the grid is down? Most systems don't and yet many people don't realize this.
No standard grid tie system will work when the grid goes down. Some will partially work if the string inverters have the Secure Power option like SMA.
The only other type of grid tie would be a hybrid that includes a battery system which will cost a lot more that the prices the OP is getting.
Less dependence can mean a lot of things. It could mean just reducing their electric bill by generating a % of their own power. It does not necessarily mean being off grid or being able to generate power when the grid goes down. Most cost efficient way to do that is use a generator.
