The cost per watt-peak of solar power fell from $ 10.80 in 1998 to $ 7.50 in 2008:

However, most of the solar power until now has been provided by silicon panels. Silicon was initially chosen because we already had factories for silicon semiconductor. We are now making materials optimised for solar cell performance, like cadmium telluride (CdTe) and CIGS (Copper Indium Gallium (di)Selenide).
First Solar has built a CdTe power station at about $ 3-3.50 per Watt-peak. It costs them about $ 0.85 to manufacture a Wp of panel:

So to get your
So to work out your cost, multiply your power output in watts-peak by about $ 3.50 (US). Hawaii probably gets something like 2000kWh/Wp-year, so it depends on how many solar panels you think you need.
