Hi Hizir,
 
	Understood the mechanism and I can insert the right price for each panel, then it calculate the whole array's price correctly.
 
	But if I change to mode "by Wp", the price for each panel (USD/Wp) is not correct.
 
	You can see my attached photos (and try yourself with 02 different panels in one project): 
 
	- Panel 660Wp: 137.94 usd/pcs (0.209usd/wp)
 
	- Panel 665Wp: 138.98 usd/pcs (0.209usd/wp)
 
	Switch to "By Wp" mode, the total value is still correct, but the component price is displayed wrong:
 
	- Panel 660Wp: 0.11 usd/wp > wrong.
 
	- Panel 665Wp: 0.10usd/wp > wrong.
 
	We can still make it correctly by insert price to the panfile, but I think you guys should check and fix this in the next version.
