We can barely avoid blackout with the grid we have now and...
If you need 1,000kWh electric power per month (the current average), then you will need 1,000/36 panels = 28 solar panels. A single 300w panel measures 3.5 feet by 5 feet so you will need nearly 400 square feet of roof space to install a system of this size, and you should expect to pay around $22,000 for the installation and equipment. and then add maintenance and repair.
400SF = 20 x20' .and this is a roof facing the right way, south. likely only half one's roof faces that way and many houses don't have a south-facing roof.
That average electric usage is with most homes using fossil fuel for home heating. Adding home heating would about double the demand, so we likely need close to 30x30' (28.3x 28.3) space, facing south.
Cold hard facts nobody seems/wants to tell.
