I second your question. Is the y-axis (~ @ 4:00 onwards) a %, or is it W/m^2? What does that US$ 0.5/Wp mean (top right hand corner). Using Wp = slope x Cost, we should have Wp = 0.2 x US$, or US$ = 5 x Wp. (/m2 cancels out.)
Okay, maybe I get it. The y-axis is Efficiency as a %, with reference to a base test case of 1000 W/m^2 of solar irradiance. So, with the 1st dashed line (from lower left to top right corner) at 100% we get 1000 W output (/m^2) at a cost of $ 500 (/m^2). At 80% eff we get 800 W output at a cost of $ 400 (all figures in /m^2). So, this line represents a cost of 0.5 $/W. Lines with steeper slope imply lower cost/W, lesser slope implies higher cost/W.
A very good series!
thanks
Amazing course
Really u r explaining like a God...thank u for ur deep explanations sir...I m n love with my research after seeing these videos
can you redefine of efficiency please ?
