Try $6-7 per watt with the current technology. You might break $5/watt if you're installing a 2 megawatt system, but you're not getting anywhere near $1/watt.

Solar Panels - Sunelec : Solar Panels $1/W, PV Systems $2/W

does offer under $2 per watt systems.. the Solar panels are running around $1 a watt..




if you buy cells yourself and make the panels yourself, you can get cells around 50cents a watt..

a) Those prices are for material only- unless you're pretty talented, you're not going to want to mess with building a solar system yourself.

b) They're not complete- they don't include mounting systems and other components, so it's not like you just buy the system from them and "poof" you're ready to go.

c) The low cost systems don't have batteries storage or inverters, so you can't store power.

The $6-7 figure I quoted was for a turn-key system, furnished and installed, with inverters and battery storage, which is really the only way to go if you want to get the maximum benefit from the system. A system without storage will take forever to recoup its cost.
