I keep seeing studies like these that show that solar electricity is not that cheap.

Looks like solar costs the most and produces the least.
Which is precisely what I have been saying all along.

The only time solar becomes some what competitive is when it's installed on an existing structure that already has power hooked up to it.
To take a bare field and turn it into a solar plant you are looking at $3 per kwh over the life of the system.

I'm trying to do it for about $2 per watt installed.
I could do it cheaper than that but I want a specific type of power inverter. The sunny boy grid tie with secure power supply.
A normal grid tie inverter is useless when the power goes out. The sunny boy SPS will allow you to use up to 1600w while the sun is on the panels, it will take raw solar power and convert it to 120v 60Hz power with no batteries.
The catch is it costs about 3 times as much as a normal no thrills grid tie inverter, but it's a fraction of the price of a hybrid inverter and system.

Simple grid tie inverter = around 10 to 15 cents per watt of capacity
Secure power supply inverter= around 20 to 30 cents per watt
Hybrid = over $1 per watt by the time you add batteries.
